Science Heat review (1c.)

1. Susan wanted to build a container to keep her lemonade cool as she played volleyball on a hot sunny day. She did an experiment with different materials in order to decide what she should use in her design The results are in the table below.

Which material should Susan choose to build her container and why?

• Material #2 because it did not allow the heat to pass through easily.

• Material #2 because it allowed the heat to pass through easily.

• Material #3 because it did not allow the heat to pass through easily.

• Material #3 because it allowed the heat to pass through easily.

2. A solar cooker is a device that can be used to cook food outside using heat from the sun when electricity is not available. Ernest is going camping and wants to build a solar cooker to cook his hot dogs. Below is a table showing the choices of materials he can choose for his solar cooker.

What can Ernest conclude about his choices and which option should he use to cook his food the fastest and why?

• Choice #1 is the best insulator so he should use that.

• Choice #1 is the best conductor so he should use that.

• Choice #2 is the best conductor so he should use that.

• Choice #2 is the best insulator so he should use that.

3. Ashley is trying to earn money by opening a sno-cone stand in her neighborhood, but she is having a problem with the sno-cones melting in the hot summer sun.

Ashley has a large box to keep the sno-cones in while she tries to sell them. She also has these materials to choose from to put in or on the box:

How could Ashley create a device to keep her sno-cones from melting in the sun?

• She should create a box with tin foil and black paper to block the sun’s reflection.

• She should create a box with styrofoam and cotton balls since these materials are insulators.

• She should create a box with black paper and styrofoam since conductors and insulators built together can prevent the cones from melting.

• She should create a box with black felt and black paper since black is a conductor.

4. Riley is going to sell hot chocolate at the football game. What type of cup should she use to make sure that the hot chocolate stays hot for an extended period of time?

• Cups that conduct heat well using metal, so the cup will become warm.

• Cups that are made out of chocolate, so the buyers have a lot of chocolate

• Cups that insulate heat well using styrofoam, so the heat will stay inside the cup.

• Cups that are made out of paper so they are inexpensive, which means Riley will earn more money.

5. Two students were building a solar oven to bake chocolate chip cookies. They tested different materials by placing them in the sun for 1 hour and recorded the data in the chart below.

According to the data, which material should they use for the inside of the solar oven?

• Cardboard because it is a commonly used material.

• Aluminum foil because it is the best conductor.

• Styrofoam because it is the best insulator.

• Wood because it is heavier.

6. Students in Mrs. Williams class are tasked with using common materials to create a device that will keep ice in their container for the longest period of time. Students will be competing with their classmates to create their device. Which group of students will MOST LIKELY result in maintaining the ice the longest period of time?

• Group A puts ice inside styrofoam and then wraps the styrofoam with aluminum foil.

• Group B places ice inside cardboard and then wraps the cardboard with a black jacket

• Group C places ice inside a bunch of cotton balls and then wraps the cotton balls with styrofoam.

• Group D places ice inside aluminum foil and then wraps the aluminum foil with black construction paper.
