Energy Transfer in Matter

Lesson Grade 6

Students learn that thermal energy always flows from warmer to cooler objects, explore the three methods of heat transfer (conduction, convection, and radiation), and apply these concepts to everyday phenomena from cooking to clothing choices.

Natural Selection in Four StepsFour panels showing how natural selection works using beetles on light ground: variation in color, bird predation as selection pressure, differential survival of camouflaged beetles, and inheritance producing more light beetles in the next generationNatural Selection in Action1.
