Students used flashlights on different materials and recorded their results. Which material demonstrated a reflection of light?
Students can demonstrate reflection by doing which of the following?
Enlarging an image using a hand lens.
Measuring a shadow made by the Sun.
Observing their own image in still water.
A student held a smooth piece of aluminum foil near his face and could see himself. Then, the student crumpled up the foil, opened it back up, and looked at the foil again. He could not see himself this time. Why was he unable to see himself in the crumpled piece of foil?
The foil was uneven and trapped all of the light that traveled toward it.
The foil was uneven, and the light that hit it traveled in many different directions.
The foil absorbed the oils in Joshua's hand, and the oil caused the light to stop at the foil.
A student is planning an investigation to answer the following question: How can I use two mirrors to make a beam of light hit a certain target? The picture shows his plan. How would you help the student refine/improve his investigation to hit the target?
The student should decrease the size of his target.
The student should change the position of the mirrors.
The student should use a flashlight instead of a laser pointer.
A student is planning an investigation to answer this question: How will a mirror reflect light that strikes it at different angles? As she investigates this question, what should she change in each trial to answer this question?
The type of mirror
The location of the mirror
The location of the light she shines at the mirror
A student is planning an investigation to determine why we can see our reflection in some materials and not others. Which of the following investigations can the student perform to see the difference?
The student should compare different types of mirrors.
The student should look at the same piece of glass during the day and the night time.
The student should look into different substances with smooth and rough surface.s
The diagram shows the ways light travels or behaves when shone into water. Which beam of light is the result of refraction?
Beam A
Beam B
Beam C
A card with writing on it is viewed through a jar with water in it. Part of the writing on the card appears to be changed. The change in appearance of the writing is the result of which of the following?
Not all of the light that strikes the writing is reflected.
Light rays passing through the water are bent.
Light rays are absorbed by the glass of the jar.
Four students are planning investigations about how light is affected by different objects.
Student #1 is investigating how light interacts with paper.
Student #2 is investigating how light interacts with aluminum foil.
Student #3 is investigating how light interacts with eyeglasses.
Student #4 is investigating how light interacts with water.
How many of these investigations will cause light to be refracted?
One
Two
Three
A student sees this picture in his science textbook. He plans an investigation to see if other types of objects will produce the same effect.
Step 1 - I will get three other items to try shining a laser pointer through like this: a small bottle of hand sanitizer, a small container of clear slime, and a small piece of clear glass.
Step 2 - I will shine the laser pointer one time at each object. Each time I will shine it at a different angle.
Step 3 - I will look carefully at the path of the laser to see if the light was refracted and draw what I see.
Which step of the investigation should the student change to improve his investigation, and why?
Step 1 - He should not try the investigation with three different objects.
Step 2 - He should keep the same angle of light for each object.
Step 3 - He should not draw the results of the light's path.
Erika has found a prism in her dad's office. She takes it outside to play. As she does, sunlight hits the prism. Explain what happens as the sunlight passes through the prism.
The sunlight bends as soon as it goes through the prism since it is a different media.
The sunlight is bounced back from the prism back to Erika's hand since the prism is reflective.
The sunlight continues to go in a straight line through the prism since light travels in straight lines.
A student in the cafeteria brings a large clear cup filled with water. The student places a bright pink straw in the water. What observations can the students at the table make about the straw once it touches the water?
The straw will go in the water and there will be no difference in how light affects the water and air that the straw is in.
The water bends the straw. Once the student takes the straw out of the water, the straw will still be bent.
The straw will appear broken because light travels through water differently than water.
A student is sitting at her desk one day, and notices that the lights in her classroom have a cover over them. She wonders if these covers affect the light in any way, and decides to plan an investigation to find out if they are transparent or translucent. Which of the choices below is an investigation and will give her accurate results?
She can take off one of the covers and shine a light through the cover, looking at the light carefully on both sides.
She can interview the workers who installed the ceiling, asking if they use transparent or translucent covers.
She can do research on the internet to see if the company who builds the covers tells if they are transparent or translucent.
Students observe how light interacts with different materials and record what they see in a data table. Which material would be entered into the empty box on the data table?
Cardboard
Glass
Metal
