A solid is matter that keeps its own shape. A rock stays a rock. A spoon stays a spoon. Solids do not flow like liquids. They do not spread out like gases.
Solids have properties. A property is something you can observe about an object. Some solids are hard, like a rock. Some are soft, like a pillow. Some bend, like a rubber band. Some break, like a cracker.
Solids can be big or small, heavy or light, rough or smooth. You can describe a solid using many properties at once. A marble is small, smooth, hard, and round!
Because solids keep their shape, we can build with them. Houses, bridges, and towers are all made of solids. This week you will explore solids and even build with them!
1. What does a solid always keep?
2. What is a property?
3. Name a solid that is soft.
4. Why can we build houses out of solids?
Write what each word means in your own words.
Write two properties for each solid.
| Solid | Property 1 | Property 2 |
|---|---|---|
| Rock | ||
| Pillow | ||
| Rubber band | ||
| Ice cube | ||
| Sandpaper |
Write T for true or F for false in each circle.
Draw a hard solid, a soft solid, and a bendy solid. Label each.
| Question | Rock | Sponge |
|---|---|---|
| Hard or soft? | ||
| Heavy or light? | ||
| Can it bend or squish? |

6. We can ______________ towers and houses with solids.
You need: blocks, boxes, books, cups, or other stackable solids.
Build the tallest tower you can with three different solids. Which solid worked best at the bottom? Record your results!
| Solid I used | Where I put it | Did it work well? |
|---|---|---|
You will drop solids into water to see which sink and which float. Start collecting small solids to test. Ask a grown-up which ones can get wet!
