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:
Overall, I’m really happy with the results! Questions, comments, concerns? Leave them below!
