Grade 4 energy and electricity
Forms of energy, circuits, and where our power comes from. Here is what we have for Grade 4.
Lessons
Winter Science: Ice, Snow and Staying Warm
Why roads get salted, which mitten really works, how a seal stays warm in icy water, and why a mouse is cosier under the snow than on top of it. Four hands-on lessons on ice, heat and insulation.
Simple Circuits: Make It Light Up
Light a bulb with one wire, hunt for materials that let electricity through, find out why string lights all go dark at once, and build a burglar alarm. Four hands-on lessons on closed loops, safe and cheap.
Keep It Cool: Ice, Insulation and Staying Comfortable
Why salt makes ice melt faster, which wrap keeps a drink coldest, how a seal and a fennec fox each keep their body temperature steady, and how to build a cool box that beats the heat. Four hands-on lessons that start from a freezer and work in any climate.
