2nd grade Science Experiment: Make It Balance!

Here are the science standards we learned in the Make It Balance experiment:
  • Create and use representational models to demonstrate stable balanced systems.
  • Communicate observations and compare stability and motion, using precise vocabulary.
  • Analyze and interpret observational data.
Equipment List:

Cardboard hand, clothespin(s), flexible wires, and pencils.

WE ARE SCIENTISTS!

I can balance my item using a counterweight.

You have to put the clothespin in just the right place to find an objects balance point.

It's so exciting when I get it right!

I found the center of gravity by balancing my cardboard pencil.

We all got it now!  















The new balance challenge:  Can you balance your pencil using a wire, two clothespins and a pencil?


I used counterweights.

Sometimes the pencil really leans out until it finds its balance point.  Kind of like a surfer leaning to stay on his board, while riding a wave.  Its all science!



We got it!


Josiah's favorite subject is Science!



I can balance the pencil on my foot!



This is my "I got it" face!  Go Cash!
