A while back I wrote about turning my classroom into bakery. Here’s the original post: Let Them Eat Bread  Since then, I’ve had a lot of people ask for the document I used for the yeast lab. I apologize that it took me forever to post it, but better late than never. So here it is: YeastLab. I have my students do a formal lab report with this one. Their initial hypotheses are usually all over the place, and someone always says the salt will kill the yeast.

This year I used both the yeast tube lab and the bread baking in our cellular respiration unit. I started the unit by having them write in their journals in response to “Why does bread dough rise?”. It was important to emphasize to them to just write whatever they thought. This gave me a good idea what their pre-conceptions were, but also allowed me to show growth throughout the unit. After baking the bread, they had a one question quiz. “Write one paragraph explaining why bread dough rises.” They had to include the words cellular respiration, yeast, glucose, and carbon dioxide. I graded them not by marking their answers right or wrong, but by asking questions. Then I put them into pairs based on their scores and had them revise together to raise their scores. I feel like they got a lot more out of it this year.

If you try it out, let me know what works and what doesn’t. I really appreciate your feedback!  Happy Baking!!

Political Biology

Today I’m sharing another one of my quarter projects, meaning my kids work on it once a week for 9 weeks. I really like this one because it gives the students the freedom to dive into a topic that they really are interested in. It requires them to find out what is happening in the real world and decide for themselves what the best solution is.

Each student chooses a biological topic (ie. global warming, animal conservation, organic foods) and then researches political connections. The end product is a letter to a politician explaining what the problem is and what they feel the government should (or should not) do about it. In some cases, the government is not involved at all but the students can take the side that it should be! They can disagree or agree with what is already being done (which means they have to actually know what is going on). Here’s the student instructions and research questions: Politician letter   I’ve done this project with my freshmen bio and with my upperclassmen bio 2, so there are modifications for both levels. My freshmen all write to President Obama. My upperclassmen have to choose their own politician (anyone but Obama).  They edit each other’s letters, and then I edit again if needed. I do actually mail their letters (well, the ones that meet all the criteria). We always get a response from the White House (though it takes a few months). I post the letter in my room, and the kids really get a kick out of it. Some of the other politicians will respond as well, and I give those letters to the student who wrote them.

Here’s what’s great about this project:

-They have to think for themselves. They can’t defend their solution with “my parents say”. We also do a discussion day where they tell the class their problem and solution, and then the class gets to ask questions to make them strengthen their defense.

-Writing a letter that will actually be sent gets them to put in more effort. It gives the whole project a purpose beyond “it’s good to know”. It does make them feel important and show them their opinion is valued.

-It’s great way to teach about credible sources and even bring in primary literature if your students are ready for it!

Teachers Travel, Too!

IMG_0907

This summer seems to be flying by… even faster than most! I’ve been fortunate enough to travel a lot and visit places I’ve never seen before. But the highlight happened at a professional development last week. That’s right, a SUMMER PROFESSIONAL DEVELOPMENT.

I spent five days at the Centers for Disease Control and Prevention (CDC) in Atlanta for their Science Ambassador program. I joined 31 other high school and middle school teachers from around the country (and 1 from Canada) to build curriculum aligned to the Next Generation Science Standards. The curriculum will be published (after revisions and the final clearance by the “powers that be” at the CDC) sometime in the future, but in the mean time feel free to check out the work that previous Science Ambassadors have done here.

We worked in teams of 4 and each team had a CDC Subject Matter Expert (SME, the CDC is huge on acronyms). My team is working on a lesson on radon and its link to lung cancer. We had an incredible expert from the CDC Comprehensive Cancer Control Branch.

While the curriculum building was the main goal, here are some of the other highlights from my week:

All of us Ambassadors!

All of us Ambassadors!

The whole week was a lot of work, and at the end of it my brain was exhausted (as were my feet, Atlanta is hilly!). But this was such an inspirational experience. Everyone we met there is so passionate about their work and you truly get the feeling that they are in it for the greater good. It also made me realize the influence that us lowly teachers have when it comes to public health. We really have a chance to make a positive change. My very strong suggestion to you is to keep an eye on this program and when applications open for next summer, APPLY! Here’s the info: CDC Science Ambassador Program

The Dream House Challenge

Our last unit of the year in freshmen bio is the environment. It is really one of my favorites because there are just so many great, hands-on ways to teach kids. Last year, we built compost containers (I wrote about them here), but this year we just ran out of time. But have no fear- we did another project that I loved and hope to be able to do again in the future.

We spent a good deal of time talking about traditional and alternative energy sources. Students worked in groups and each did a brief presentation to the class on one type (ie. coal, hydro, solar, nuclear). We talked about recycling, composting, and zero waste. Then I set them loose to design and build a (model) dream house. The dream was to be as eco and environmentally friendly as possible. Some made it known that wasn’t THEIR dream house… but too bad for them.

They worked in groups of 2 or 3, which I let them pick… sort of. I split the class into 2 or 4 groups and they had to choose someone from another group. I strategically put all the “hands-on” kids in one group, the creative thinkers in another. Each student was given the instructions and the rubric (which included due dates for each step) on GoogleDrive.  Here they are: Dream House Challenge    DreamHouseChallengeRubrics

They had about 2 weeks total to work on this, which really could’ve been longer… Here is how we approached it step by step:

Step 1: Pick the location of your home. I was more interested in the type of environment than a place (at first, some picked California… which I pointed out could mean lots of different environments). They have to think about the pros and cons of that environment (ie. temperature, seasons, rainfall, sun/shade).

Step 2: Research ecofriendly homes and design your own. I really encouraged them to be creative, it didn’t have to look like any house we’d ever seen.  They had to make a blueprint and calculate square footage. We measured my classroom as a reference point. Students used the app Floor Planner on Chrome to create their blueprint. It’s a free app, but you can only save one design at a time and it’s not collaborative (only one account can work on it). Beware- this app is ADDICTIVE! If you were ever a slave to The Sims (yep, I was) this can suck you in.

 In the meantime… I had a local solar power installation expert come talk to my kids. Each group came up with 3 questions ahead of time, which helped a lot. He was great…. Check out his blog!

Step 3: Use your blueprint to build the model of your house! They could use whatever supplies they wanted, but it had to match the blueprint (which means the inside had to be visible). In addition to the model, they also had to turn in a written explanation of their choices (ie. “we are using solar panels because….” “our house is in a forest because…”). And their model had to show whatever was in the explanation.

Step 4: Present your model to the class and convince us it is the ultimate ecofriendly, environmental dream home. Here’s what I really loved- they graded each other’s models. The rubric is divided into “Peer Review” and “Teacher Review”. After everyone is done presenting, a rubric is put next to each model. The students go around and put a tally mark for whatever grade they think it deserves. Then I average the scores.

Here are some of my favorites:

They built a tree house for a rainforest... and included a sloth sanctuary.

Cut & Paste- Old School Style

So many people have responded and pinned my first post on how I use notebooks in my classes that I thought I would give you an update. I still use these notebooks for both freshmen biology and Anatomy & Physiology (upperclassmen). I am using the same setup as discussed in the previous post. I love having them grade each other’s (according to an easy to follow rubric). It saves me time! Having said that, I don’t really check for “right” answers. Most of the work we do in the notebooks in enrichment/explain in your own words type work. I will walk around and help while they are working and from time to time do a spot check by grabbing a notebook out of the box. But honestly, I’ve never had an issue with a kid not at least trying. And when they have questions (which they often do because some of the activities require them to think differently than they are used to), THEY ASK! So here are some of the types of activities we used this past school year. Some of these are from workbooks, so I can’t post them here, but I will share whatever I can…. feel free to “reinvent” them for your own students!

Pre-unit Assessments: Have the students take some sort of little assessment at the start of a unit to see what they really know. It’s just as much for them to see their growth as for me, so why not share the results with them? This particular example was at the very start of the Anatomy class. They have to label which section of the body each part is in (A,B,C,D,E). By the end of the year we cover them all.

IMG_0631

Enrichment/Check for Understanding Activities:

Organelle Flip Books: Pretty simple. Fold strips of paper so that they fit inside of each other. Label the flaps. Staple them at the top and glue the booklet in to the notebook. Then on put a description and a picture above the label. I try to push them not to copy the description out of their book, but to put it in their own words.

IMG_0651IMG_0650

Labeling Diagrams: I use these a lot in Anatomy. After we’ve been working on the parts for a few days I will have them try to label a blank diagram (and usually not the exact one we already went over) in their notebook. I tell them to try without their notes first, but of course use them if they really need them. It’s another way for them to assess their own learning and see where they need to study more.

Here’s one of the docs: Carpal Tarsal Labeling

IMG_0648IMG_0647

Describe the Function: Sometimes (like the digestive example below) I will print out all the parts of whatever system we are on and pass them around. Each student takes three and has to describe their functions. The second example is a little deeper, they have to describe the parts of a part in the flip book. They also had to draw the part themselves!

IMG_0649IMG_0633

Body Part Relationships: In this example, they have to give three pairs of muscles that work together. They give the names and the functions of the muscles. You could do this with any body systems.

IMG_0643

Word Maps: There are two ways I do this. The first is to put a concept map on the board, or give them a paper to copy (I only make enough copies for one class and can reuse them each year). Sometimes they have a word bank, sometimes they don’t. They have a few minutes to fill it in and then we go over it or I make them show it to me before they can put their notebook away.

The second, and their least favorite way, is I give them a list of words and tell them to create their own map. We usually do this type of activity at the end of a unit, so they are important terms for the upcoming test. They can organize the words in whatever way makes sense to them, but they have to be able to explain it to me.

IMG_0642IMG_0645

Review Questions: Another end of unit activity, I come up with several short answer questions and pass them out. Each student takes three and answers them in their notebooks. This is a good way for them to judge how well they understand the topics and how prepared they are for the test.

IMG_0644

Information Scavenger Hunt: I put questions in the boxes. It is usually information from the notes we did the day before. They have to go around and get the answers from each other. They put the initials of the student who gave them the answer in the box.

The example below is for the reproductive system. I really love it for this topic because it gets them more comfortable saying the words out loud… and that’s half the battle!

Term Scavenger Hunt

IMG_0639

Review Worksheets: Lots of fill in the blanks and crossword puzzles. These are activities they can do in the first few minutes of class.

IMG_0638IMG_0636

Word Parts & Examples:

We set two pages aside at the start of the year for word parts. We add to the list as the year goes on. The anatomy list includes terms of movement. Each student gets a few pictures (we did these ones the year of the winter Olympics) and has to identify three movements using our terms.

IMG_0641IMG_0634

Of course I am always looking for new activities and ways to improve my notebooks. I recently came across a blog post on Interactive Notebooks with some great ideas! Two things in particular I love are the Parent Reflections and Teach Someone Something forms. It makes me nervous for students to take their notebooks out of the room, but I know that it would be a valuable activity and I love letting parents in on what they are learning.

As always, let me know if you have suggestions, questions, or comments!

 

“Today we made pee….” 

Last summer I attended a workshop through the University of Illinois’s extension campus. It was called “Mellow Yellow” and it was simply wonderful. Not only did they refresh my knowledge of kidney function (and dysfunction), but they gave us several hands on activities that were ready to use with students. The concepts that tied it all together were osmosis and diffusion, making it a great way to hook freshmen general bio students (face it, they’re interested in pee).

But what I am sharing today is a simulation that I use with my Anatomy & Physiology students. Again, this is in no way my own creation…. But I tried it with my students for the first time this past week and not only did they like it a lot, but I saw so many “ah-hah light bulbs” going off over their heads that I’m convinced it’s too good not to share.

Students obviously have to have a basic understanding of anatomy and I gave them an internal kidney diagram to look at as we went throught it. You use cheap, easy to find materials. I listed the specifics in the doc at the end, but the beads in water represent different components within blood, cups for blood vessels, a bowl and Latch-hook canvas are the kidney parts. 

Here’s how it works: 

IMG_0381  IMG_0383

Start with all the beads and water in the Renal Artery cup. Put the latch-hook canvas over the bowl (AKA the nephron and glomerulus) and pure the “blood” over it.

IMG_0385

Right away the large blood components (red blood cells, white blood cells, and proteins) are caught in the filter. Move those into the Renal Vein cup. 

IMG_0387IMG_0389IMG_0390

Use the correct transporter proteins (colored spoons) to move the glucose, amino acids, and some of the salt out of the kidney and into the Renal Vein cup. This models reabsorption by the body (AKA diffusion). Stress that each spoon can only move that one specific molecule… That’s how it really works! This will take the kids a while (I have them work in pairs), and they’ll be amazed that your body does this so quickly in real life. 

IMG_0393

Last step… I ask what’s missing from the “blood” in the Renal vein. Thankfully, most of them notice there’s no water! Use the pipette or an eye dropper to simulate osmosis and move water from the nephron to the renal vein. 

IMG_0395

And that’s it. What’s left in the bowl is urine! It travels through the ureter and into the bladder. I finish up by asking what would happen if the glomerulus had a hole and that brings us to the next lesson on dialysis…. Which I’m hoping to actually have time for in next year’s class! 

Here’s my document with all the instructions if you want to save it:  Kidney Simulation

Florida and Grad School and Facebook, Oh My!

I’m coming up for air just for a quick post. It’s been a BUSY month, and it’s not slowing down anytime soon. First up, I was in Orlando for a meeting with the Life Science Teacher Resource Center. You all know how much I love them, but this sealed the deal. I want to tell you all about it, but that will have to wait until I have time to do that post justice.

Mickey and Me!

Mickey and Me!

The following week I started grad school. I am getting my Masters of Science Teaching Biology from the University of Illinois (online). EVERYTHING about this terrifies me. I know online classes are not my “ideal learning style” and it’s not like I had a whole lot of time to kill to start with. I felt a little selfish when I first started for taking so much time away from my family and students to work on assignments (grading can wait), but now I see that this is already making me a better teacher and allowing me to make new connections through information with my family and friends. I just finished my third week (1 day early, by the way!) and I really love it. I am currently taking Sustainability and Global Change, and want to share some of the awesome resources with you here.

How Wolves Change Rivers: YouTube video, under 5 minutes, about reintroducing Yellowstone wolves is such a simple, but powerful example of a keystone species. I shared that video with a friend of mine who teaches geography, and she showed it her class then next day (the timing just worked perfectly!).

How Many People Can Live on Planet Earth: Another youtuber, this one is 45 minutes. But it is SO very interesting! I love that they point out the importance of educating women as a part of the solution. I’m planning to show this one  to my freshmen this spring.

And finally, podcasts. Yes, just podcasts in general. I started listening to them and the one that has me hooked is Horizontal Transfer. Those of you familiar with Bozeman Science will recognize Paul Anderson. At the end of each episode they give their “TWIL” (This Week I Learned), so  this week I started a “TWIL” activity in my HS bio classes. On Friday, each kid shared something the read, saw, or discussed with the class (anything related to biology). I also shared with them what I had read about for my grad school assignment. I have a refreshed perspective on what it’s like to be a student and want to share with them that I am still learning too. I hope they realize learning is a life-long process and will take that with them when they leave my room.

Last thing! Over winter break, I started a facebook page for this blog! Since I rarely find time to write whole blog posts, it’s a way for me to share little tidbits I come across. I’d love for you to check it out!

The Ultimate Bubble Blowing Champion

IMG_1516

Today’s my last day of winter break. I’m sure my students are just as excited to go back as I am (and are also secretly hoping for a snow day). That first day back is always a tough one. They (and I) have been staying up late and sleeping in for two weeks. With all those visions of sugar plum fairies dancing in our heads, there’s little room for biology. And BAM! We’re back to school.

I give me freshman a pretty easy transition back to class. We have a bubble blowing contest. But it’s not all fun and games…. they have to do a lab report. It’s a great way to review concepts we used last semester (ie. control variables, hypotheses, graphing) and get them a little sugared up to get through the day. Here’s the lab template my kids use:   Lab Write Up Template  They have this glued in to their lab notebooks so that it cannot get lost. Usually they write their reports on a separate paper but I think I’m going to have them type them on a GoogleDoc and share it with me this time.

I go to the dollar store and buy a bunch of different types of gum. Then I put them in groups of 2 or 3 and each group has to come up with their own hypothesis. Some will test different types, some different people. I even have had groups test the number of chews before blowing a bubble. Once each group has figured out how to blow their biggest bubble, the groups compete for the title of Ultimate Bubble Blowing Champion!

Last year's winner!

Last year’s winner!

So simple  and they have a lot of fun with it. Try it for yourself! Have other activities for the post-winter break blahs? Share them in the comments!
