Objects and Materials
Name one material something can be made of?
What is metal,wood,plastic.
What property describes how something feels when you touch it?
What is texture.
If you cut a big piece of playdough in half, does the color change? (Yes or No) Explain.
No. Color stays the same when size changes.
What do we mean when we say "light passes through" something? Give an example of something light can pass through.
Light passes through = you can see light travel through it (example: clear plastic, glass).
Tell one object in the classroom and the material it is mostly made from.
What is a desk — wood; chair — plastic; water bottle — metal.
Name a property that tells us how heavy something feels.
What is Mass (or weight).
Which properties change when you make an object smaller: length, color, mass? Circle the ones that change.
What is Length and mass change; color does not.
Name something that blocks all the light and something that lets some light through.
Blocks all light: metal, wood; lets some light: wax paper, thin fabric.
True or False: An object can be made of more than one material. Explain your answer.
What is True. Many objects are made of more than one material (example: a toy with metal axles and plastic body).
Choose an object and describe its color and texture.
What is any reasonable classroom example (e.g., red, bumpy).
You have a big piece of sponge and a small piece of the same sponge. Which one has more mass? Which physical properties stay the same?
Bigger piece has more mass; color, texture, and ability to dissolve (if same material) stay the same.
If you put more sheets of the same paper on top of a flashlight, what happens to the amount of light you see? Explain.
Less light will get through as you add more sheets — light becomes dimmer.
Give two different materials you could use to make a toy car. Explain why those materials might work.
What is a plastic body (light), metal wheels (strong), rubber tires (grippy).
What property would you use to tell two rocks apart? Give two properties you could compare.
Examples: color and texture; size and weight; hardness and flexibility.
Give an example of a property that does NOT change when you cut something into smaller pieces, and one that DOES change.
Does not change: color; Does change: mass or length.
Choose a material that lets some light through (for example, wax paper). Describe how you could test whether more of that material makes less light get through.
Example test: place flashlight behind 1, 2, 3 layers and observe brightness; record results.
Look at a spoon. List the materials that could make a spoon and say one physical property of each material (for example: metal — shiny; plastic — light).
spoon — metal (shiny, hard), plastic (light, smooth), wood (light, rougher).
A fabric smells sweet and another fabric has no smell. Which property is being described? Give another example of that property.
Smell (odor). Example: flowers have smell; soap has smell; stones have little smell.
Two pieces of the same material are different sizes. Design a simple test you could do to show which properties stay the same.
Example test: compare color and texture by sight/touch (stay same); weigh both pieces to show mass changes.
You have three identical boxes made from the same material but with different amounts of holes cut in them. Predict which box will let the most light through and explain why.
The box with the most holes will let the most light through because more openings allow more light to pass.
