Goal: To design and construct a rubber ducky launcher that can land in a giant IKEA leaf from 4 meters away.
1) draw the design
2) construct the launcher
3) test the launcher
4) record the results of the trials
5) adjust based on results
We LOVE failure. When we fail and adjust, we act like scientists.
The upper graders met and agreed on rules to make things fair:
1) You must only use the materials given, but you do not need to use all the materials.
2) You may use your own strength to pull the ducky back, but you may not use your strength
3) You are allowed 3 trials.
4) The launcher must be able to be used multiple times.
5) No ducks may be harmed in the process (no cutting the heads off the ducks).
When you adjust your design, leave the original design in your lab. Don't cross it off, don't erase it, leave it. Write about how you changed your design so others can learn from your failures and adjustments.
Well, that explains my near-duck experience yesterday! I'm excited to see some launchers!
ReplyDeleteOh my goodness. This math lab has been all the buzz around our house and the kids can't stop talking about their launchers and their ideas. So fun. I'm also excited to see the launchers. :)
