|
|
|
Which of the following shows light being reflected? |
A. Cat looking in a mirror B. Sun shining through clouds C. Thermometer in a glass of water D. Flashlight |
|
|
A picture of a glass of water with a spoon inside is pictured. How is light behaving in the picture? |
A. reversed B. reflected C. refracted D. absorbed |
|
|
Which of the following would reflect rather than refract light? |
A. a small lens B. a shiny mirror C. a dull black paper D. a magnifying glass |
|
|
Sam completed an experiment to see what color absorbs more light. Here is the data: Color of Fabric % of ice melt in 15 min Yellow 20% Red 40% Black 68% White 10% Which color absorbed more light? |
A. yellow B. red C. Black D. White |
|
|
Describe the evidence that proves the color your chose absorbed the most light. Explain why it absorbed the most light. |
Evidence 2pt The black fabric melted by 68% in 15 minutes. Reasoning 2pt Because Black absorbs all the light and so it absorbs all the light energy so it gets warmer. |
|
|
You shine a white light on a wall. You see that the wall is blue. Why does the wall look blue? |
a. the absorbs blue wavelength b. red wavelengths bounce off the wall c. the wall absorbs white light d. blue wave lengths bounce off the wall |
|
|
What happens when light strikes a smooth shiny surface like a mirror? |
A. the light is refracted B. the light is absorbed C. The light is reflected D. the light is transmitted |
|
|
White light is... |
A. the absence of all light B. All the colors mixed together C. Light that travels faster than other light D. Light that travels slower than other light |
|
|
Check all statements that are true: |
Light Travels in a straight line X Light travels slower than sound Light can travel through wood Light does not change speeds when it moves from one medium to another Light can travel in space X Light travels at different speeds X |
|
|
Which of these words describes the material in a stained glass window? |
A. Opaque B. Transparent C. Translucent D. Refractive |
|
|
Which type of object does NOT create a shadow? |
A. An opaque objects B. A transparent objects C. A translucent object D. A luminous object |
|
|
Draw the sun where the shadow would be the shortest |
Look for an example in your notes: |
|
|
Checkmark all the objects that are transparent |
Dog Glasses X apple glass of water X Magnifying glass X lamp window X stained glass window soccer ball |
|
|
There is a picture of a glass of water and a pencil inside. Explain why the pencil looks broken. |
The pencil looks broken because light moves from air through glass then into water. When light moves from one medium to another it changes speed and that makes it look broken |
|
|
Which question is testable? |
A. Does the angle of the light affect the temperature of the object? B. Why does black absorb more light than white? |
|
|
Explain why it is testable? |
A testable question can be measured and you can do an experiment to measure the temp of an object. Question B is a research question. |
|
|
A boy is looking through a periscope. Draw arrows and explain how the light rays move so that this boy can see through the periscope. |
Light shines on the apple. The apple reflects the light into the top of the periscope. The light is reflected on the top mirror to the bottom mirror and then reflected into the eyes. |
|
|
You have a picture of a tree and the shadow is right in front. Draw the sun where it should be to create this shadow. |
The sun should be to the left top side of the tree. |
|
|
There is a picture of a boy on the left and a girl on the right tossing a ball back and forth. The sun is shining over the girl. Draw arrows to show the path of the light rays so that the girl can see the ball. |
Arrows should go from the sun to the ball to the girl. |
