Hey 61 M again I'm back to tell you about the science chapter we did.  The chapter was heat and matter so hear are some things.  I learned how convection, conduction, and radiation works I also learned how a microwave works and we learned how a laptop was cooled.   The thing i liked best about this chapter is the popcorn lab it was fun and the popcorn was tasty.  I know that some sources of radiation is a microwave the sun and a camp fire what are some more?
