Explore Together (indoors): Build Ramps
STEM Key Concepts: Understand that a ramp, or inclined plane, is a surface with one end higher than the other; Recognize that an object placed on an inclined plane will roll, slide, or stay put
ELA Focus Skills: Predicting, Speaking and Listening, Vocabulary
Educator Prep: Select an indoor area where children can build ramps. You may choose to have ramps built facing a wall so that rolling objects will stop at the wall, or you may want to use a cushion as a bumper. Noticing the distance that objects roll after leaving the ramp is an important part of exploration, so finding adequate space and opportunities for children to do this is valuable.
Tell children that they will work with a small group to build more ramps. Explain that a ramp is also called an inclined plane. Assign groups an area where they can build a ramp.
Allow children to freely explore the materials. Encourage them to notice how the objects are alike or different (size, shape, texture, etc.) before they send them down the ramp.
Observe children closely as they work and notice what captures their attention so you can engage them in conversation. Discuss what they are making or doing and what they are noticing and wondering. Ask questions such as,
- What do you think will happen if you place the marker pointing down on the ramp? Can you find other objects that move like that?
- What did you notice about the way the box moved when you made the slanted plane steeper?
Encourage children to use vocabulary such as ramp, roll, slide, inclined plane, fast, and slow as they share their ideas and ask questions. Take pictures (or have children take pictures) of the ramp constructions or have children draw a picture of their ramp so they can revisit the structures even after they are dismantled.
Reflect and Share
Have children share their ramps and discoveries. Show some of the photos and have children describe how they are being scientists. Prompt discussion by asking questions such as,
- Why do you think the box slid to the bottom of the ramp but the rock didn’t slide all the way to the bottom?
- What did you notice about the way the pinecone moved down the ramp?
- How did you get the tin can to go faster than the cube?
