How does a wind-up toy work?
That was the important question for the quest of the day.
First, we looked at the outside of the toy and drew it on our lab report.
We each came up with a hypothesis as to how it works.
Another hypothesis.
Then we got out the screwdrivers and did some
reverse engineering.
We learned how to use Phillips screwdrivers.
We used flathead screwdrivers to pry them open.
When we got inside the toy, we discovered another box
that needed to be opened.
As we opened them up, we laid out the parts,
drew them, and labeled them.
With a lot of twisting and turning and prying,
we discovered the most important part - the torsion spring!
Notice the sprung torsion spring.
We tried to put them back together and had no success.
What a wonderful, complicated, fun little toy!
So many skills practiced. Here are a few:
- curiosity
- prediction
- observation
- small motor
- innovation
- filling out a lab report
- collaboration
- analytical/critical thinking
These skills might come in handy
for when we come up
with our own inventions!
