Forms of Energy
Five Forms of Energy There are five forms of energy that we’ve discussed so far. Can you name and describe each of them ? (Refer to your science notes, if needed). 1. Light energy 2. Thermal energy 3. Electrical energy 4. Mechanical energy 5. Sound energy
Light Energy is… a form of energy which our eyes can detect
Heat/Thermal Energy is… energy related to the temperature of an object
Electrical Energy is… energy that is absorbed or delivered by an electric circuit
Mechanical Energy is… energy of motion or movement
Sound Energy is… energy produced by vibrations
Conductors and Insulators • Conductors- allows electricity and heat to flow through • Insulator- does NOT allow electricity and heat to flow through Which spoon(s) would be an insulator and which would be a conductor? Explain. https: //www. youtube. com/watch? feature=player_detailpage&v=u. Cn. Zhzv. WFo. Y
Draw a T-chart in your notebook and sort the items as conductors or insulators with your neighbor conductor insulator Copper penny Plastic spoon Metal spoon Styrofoam cup Copper wire Rubber tires Metal paperclip Styrofoam ice chest Wooden block
Create a Venn Diagram in your notebook and compare and contrast conductors and insulators with your neighbor. Let’s see who can include the most facts in their diagram after 5 minutes! GO! conductors insulators
Force What is force? Force is a push or pull that can change the position or motion of an object/material How to use a spring scale (optional video): https: //www. youtube. com/watch? v=AFu 1 adv. Enhw How is force measured? Force is measure used a spring scale. Force is measure in Newtons (N).
Force Continued… Balloon Powered Car Lab https: //www. youtube. com/watch? v=3 Dw 6 N 0 Tn_s. U Discuss: • What would have happened if the balloon had more force (bigger balloon)? • What would have happened if the balloon had less force (smaller balloon)? • Does the amount of force applied affect the speed of an object?
