Exciting Energy

This week we have been learning about light, heat, and sound energy. We discovered that our sun is our greatest sort of light and heat for our world. We created a circle map where we drew pictures of items that give off light. Then, we covered our pictures with glitter to illustrate the light that they give off.





Then, we studied about heat energy (thermal energy) and took this fun opportunity to use a heat source to make hot chocolate. We also used our hot chocolate to melt candy canes and discussed some of the effects heat can have on objects.







Finally, we learned about the science of sound and how sound energy can be used to make music. We learned about how our vocal chords work and felt them vibrate. Then, we explored musical instruments made out of recyclable materials. We also created our own shakers and had a sing-a-long. Here are some videos from our explorations with sound:
