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). Light energy Thermal energy Electrical energy Mechanical energy 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

energy that is absorbed or delivered by an electric circuit 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=uCnZhzvWFoY

Draw a T-chart in your notebook and sort the items as conductors or insulators with your neighbor Metal spoon Plastic spoon conductor insulator Styrofoam cup Copper penny 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? How is force measured? Force is a push or pull that can change the position or motion of an object/material How is force measured? Force is measure used a spring scale. Force is measure in Newtons (N). How to use a spring scale (optional video): https://www.youtube.com/watch?v=AFu1advEnhw

Force Continued… Balloon Powered Car Lab https://www. youtube 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?

Balloon Powered Car Trials Help to chart the balloon data! Be sure to label the axis’ before charting! Force Applied Time to travel 5 m 1 N 6 seconds 2N 4 seconds 3N 2 seconds Title Title

ANSWER KEY! conductor insulator Metal spoon Plastic spoon Styrofoam cup Copper penny Metal paperclip Metal spoon Copper wire Plastic spoon Styrofoam ice chest Rubber tires Wooden block Styrofoam cup Copper penny Copper wire Rubber tires Metal paperclip Styrofoam ice chest Wooden block

ANSWER KEY! conductors insulators Does not allow heat and electricity to flow through Rubber Plastic Wood Allows heat and electricity to flow through Metal Can be placed in a circuit Made of matter
