The students will use movement to act out the molecules in the three states of matter.
- Graphic organizer
- Large area (such as outdoors)
The students will identify and model the molecular structure of a solid, liquid and gas.
Whole group instruction: Create a chart with solid, liquid, and gas as the headings. Have students add to the list everything they know about the states of matter. Take a bar of soap and discuss all the physical properties of that solid. Add water to the soap to turn it into a liquid. Discuss properties of a liquid and how it is different than a solid. Blow a bubble with the soap and discuss the properties of a gas and compare it to the solid and liquid.
Allow the students to use their bodies to show the molecules in the three states of matter.
Solid: All the students try to stand in a four square area.
Liquid: The students walk slowly with their elbow at their waist. They must touch another student at all time and stay within a given area.
Gas: Students move out and cover the entire area.
Play a game of “I Spy” describing physical properties of a solid, liquid, or gas. For example: I spy some that has a shape of its own and has molecules that are tightly packed together.
Students will draw a picture of a solid, liquid, and gas in their science journals. The students will then add what the molecules look like in each of the three pictures and write a few sentences to describe what they drew using their new vocabulary words. Use a rubric to grade based on neatness and understanding of the content.
