We're circling back to teamwork as we close out our fourth grade year.

With a partner and the rules to the right, how high of a structure can you create with 100 index cards and 24 inches of tape.

It's fun to see how far we've come in our planning, executing, revising, problem solving, and teamwork skills. This sort of challenge was very difficult at the beginning of the year, but now that we've grown as thinkers, mathematicians, scientists, fourth graders, and partners, this was a lot of fun...whether our tower was the highest or not!

This week we've explored how waves are a transfer of energy from one place to another. A tsunami is formed when an earthquake disturbs the ocean floor; the energy creates a wave that travels through the water. A sound wave is similar. We explored sound waves created by different instruments, and then made our own sounds. Varying wavelength and amplitude changes the sound!
