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.

Which of the following materials should be used to keep his puppy as cool as possible during the day?

• 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.

Ginny and Marshall are using a rubber band, 2 markers, and a box to learn about pitch. First, they stretch a rubber band around a box. Next, they place markers under the rubber band. They can move these markers to make the section of the rubber band that’s being plucked shorter and longer. 

Marshall makes a sound by placing the markers as seen in the picture below. He plucks the rubber band with his finger. 

             

Ginny wants to make a higher pitch sound than the one that Marshall made. Which picture shows how she should place the markers so that when she plucks the rubber band, it will result in a higher pitch?

Fourth grade students all created different ways to investigate sound.

Group 1

Wrapped rubber bands around a shoe box.

Group 2

Hang a ruler off the edge of a desk.

Which of the following will both groups encounter when producing sound?

• Only group 1 will hear sound because rubber bands are used to create vibrations when pulled on.

• Both groups will move an object that will create a response with a sound and vibrating objects.

• Only group 2 will hear sound because the ruler will vibrate and create a sound.

• Both groups will hear a sound, but only group 1 will observe vibrations.
