LESSON 4.1 · SC.3.P.10.1
Forms of Energy Learning goal: Identify light, heat, sound, electrical, and mechanical energy.
What to know Energy appears in different forms. A single object can involve more than one form. Identify a form from observable evidence such as light, warmth, sound, or motion. 🔎 Think like a scientist A ringing flashlight may use electrical energy and produce light, sound, and some heat.

What to know Mechanical energy can move objects. Heat can change temperature or state. Evidence of energy includes motion, sound, light, warming, and other changes. 🔎 Think like a scientist A stretched rubber band can launch a paper ball: stored energy causes motion.

What to know The Sun, flames, and many lamps produce both light and heat. Not every hot object gives visible light. Use observations safely; never touch a possible heat source. 🔎 Think like a scientist A lamp can brighten a surface and make the nearby area warmer, showing two forms of energy.

What to know Friction is a force that resists sliding surfaces. Rubbing changes some motion energy into heat. More or faster rubbing often produces a larger temperature change. 🔎 Think like a scientist Rub your palms safely for ten seconds; their temperature rises because friction produces heat.
