- 2. Multiple ChoiceIf I want to change a liquid to a gas, I need to -remove thermal energyadd thermal energydo nothing; it happens automaticallyadd mechanical energy
- 3. Multiple ChoiceElectrical circuits are comprised of a power source, wires, a load and a switch. What physical property of the wire makes it function?solubilitydensityconductivitymagnetism
- 4. Multiple ChoiceIn order to generate electricity, something has to turn the turbine which powers a generator. What type of energy would be needed to turn the turbine?LightMechanicalSoundElectrical
- 5. Multiple Choice
What behavior of light do the arrows in the picture show?TransmissionReflectionAbsorptionRefraction - 6. Multiple ChoiceA car runs on gasoline and also uses a battery. The battery powers the lights, windshield wipers, radio etc., while the gasoline allows the engine to function. If the battery is allowed to run down, what is one thing that could happen?The radio will play louderThe windshield wipers will work better.The power windows will not workThe brakes will be better
- 7. Multiple ChoiceAn electric hot plate creates thermal energy for cooking. What type of energy powers the hot plate?MechanicalElectricalLightThermal
- 8. Multiple ChoiceA girl sees her reflection in a lake while she also sees a rope tied to a boat that looks bent in the water. What behaviors of light is she observing?her face is reflection and the rope is refraction.her face is refraction and the rope is reflection.both are reflection.both are refraction
- 9. Multiple ChoiceA student wants to test the effect of a force on an object. He changes the surface type of the ramp and rolls different cars down the ramp one at a time. What is wrong with his experiment?He has too many hypothesesHe has too many variablesHe has too many carsHe has too many ramps
- 10. Multiple ChoiceUnder what conditions can electricity flow successfully through a circuit?When the circuit is closed and has a power sourceWhen the circuit has a power source and is openAny time you want it to, just flip the switchWhen the circuit is closed and has no power source.
- 11. Multiple ChoiceWhich of the following best demonstrates refraction of light?Looking through a large glass window.Looking at your image in a mirrorLooking at a star through a telescopeLooking at a light bulb glowing in a lamp
- 12. Multiple ChoiceWhich of the following is NOT an example of why using a camera to take a picture of the mountains is a good example of refraction of light?You can see your own face in the camera.The image in the camera is smaller than the real thingCameras are made of lenses which refract lightYou can see through the camera, so its not reflection
- 13. Multiple ChoiceStudents were testing force and motion in a class room. All of the following are good examples of testing the effects of force and motion EXCEPT-throwing a baseballtwo teams playing tug-o-warmeasuring the size of 2 marblespaddling a boat backwards
- 14. Multiple ChoiceWhich of the following could complete the chart?SpoonSmooth lakeHand lensShiny metal key
- 15. Multiple ChoiceStudents tested the effects of forces that act from a distance causing objects to move. They discovered that two forces affect objects in this way. The two forces are -friction and gravitygravity and magnetismmagnetism and frictiongravity and density
- 16. Multiple ChoiceWhat is shown in the image?The force needed to use a pulleyThe path light takes when it is refractedThe flow of an electrical currentThe path light takes when it is reflected
