Melts in Your Bag, Not in Your Hand

In this activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation. Learners compare the melting rate between chocolate left in the sunshine and chocolate left in the shade outside for twenty minutes on a hot sunny day. Use this demonstration to introduce learners to solar radiation as well as the importance of summer safety and sun protection. Although this works best on a hot sunny day, this activity...
