Complementary Option: Can the Air Bend Too?!
This is a wonderful topic for K-2 grades! As volunteers who assist thousands of teachers in providing a true hands-on component in their classrooms, we can attest that young students love to explore matter, comparing what can bend to what cannot. We've presented a science demonstration for close to 20 years that remains very popular. Students can pass around a play with models of what's in the AIR!. It turns out that some of the air can bend and jiggle. That's what makes the greenhouse gases special and different. Most of the air, including the part we need to breath to stay alive (oxygen) can't bend. Great subject!
