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 do research on the internet to see if the company who builds the covers tells if they are transparent or translucent on their website.
She can turn off the lights and try to see through the cover, deciding if the objects on the other side look clear or not.
She can interview the workers who installed the ceiling, asking if they use transparent or translucent covers.
She can take off one of the covers and shine a light through the cover, looking at the light carefully on both sides.
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
Cloth
On his way home from school, a student notices a car with dark, tinted windows. He wonders if the windows he is seeing are translucent or opaque, and plans the following investigation to find out:
Step 1 - Shine a laser pointer at the window from outside the car.
Step 2 - Look through the window to see if the laser’s light is shining inside the car or not.
Which of the following choices would improve his investigation?
Change step 1 - he should use a flashlight instead of a laser pointer
Change step 1 - he should look to see if he can see through the window
Change step 2 - he should look to see if he can see the laser on the outside of the window
Change step 2 - he should look at how the laser pointer’s light looks from inside the car
Jonathan wants to build a doghouse for his new puppy. His puppy will be living in the backyard. He uses a flashlight to test the following materials: frosted plastic, wood, and glass. He wants to make sure the material he uses will keep his puppy shaded and cool during the day. Below are his observations from his flashlight test.
He should use glass because it allows all light to come in, therefore, there will be no blocked light, so it will remain cool in the doghouse.
He should use frosted plastic so there is some light that can come in to keep the doghouse cool, but not too cold.
He should use a combination of all three materials to allow different amounts of light in to keep the doghouse cool.
He should use wood because it blocks all light from coming in, and this will keep the doghouse cool.
Students want to explore how light interacts with different materials. Which of the following investigations would BEST allow students to see how light interacts with different types of materials to classify them.
Take three different types of flashlights to see the amount of light that shines through a piece of construction paper.
Take three different types of flashlights to see the brightness of light when turned on in a dark classroom.
Take three different types of materials such as: aluminum foil, plastic wrap, and white paper to see the amount of light that shines through it when placed under a flashlight.
Take three different types of materials such as: cardboard, wood, and a thick blanket to see the amount of light that shines through it when placed under a flashlight.
Students conducted an experiment to classify different types of materials as opaque, transparent, or translucent. Which of the following charts correctly classifies the materials?
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?
Warming metal under a heat lamp.
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 lost its thickness, and light was able to travel through it.
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 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? Here is his plan for the investigation:
Step 1 - Place a target on the wall across from me.
Step 2 - Place two mirrors around the targets.
Step 3 - Shine a laser pointer at mirror #1. The light will reflect to mirror #2, and then to the target.
How would you help this student refine/improve his investigation to hit the target?
The student should increase the size of his 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 light
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 look in mirrors at different angles
The student should compare different types of mirrors.
The student should look at the same piece of glass during the night and day time.
The student should look into different substances with smooth and rough surfaces.
The diagram shows the ways light travels or behaves when shone into water. Which beam of light is the result of refraction?
A
B
C
D
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 the 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.
Light is not able to bounce off 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
Four
A student sees the following image 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 1 - He should not use only clear-looking materials.
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 Erica’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.
The sunlight stops traveling the moment it reaches the prism since different media make the sunlight stop moving.
A student in the cafeteria brings a large clear plastic 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 appear broken because light travels through water differently than water.
The water bends the straw. Once the student takes the straw out of the water, the straw will still be bent.
The light from the straw will bounce back to the students’ eyes so it will appear that there is no straw in 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.
