Teacher Notes for Transparency: Solids, Liquids, and Gases Matter is made of particles. These particles are arranged differently in solids, liquids, and gases. These arrangements give these states of matter certain physical properties. Solid particles are packed together. They move back and forth (vibrate). These particles never change place with each other; hence, the reason solids do not change their shape. Liquid particles move more than solids. They vibrate and they “slide” over one another inside a container. This is why they take the shape of any container. Gas particles move around the most. They not only vibrate, but also move around to bump into each other so they can fill any container. States of Matter are different because of the “stuff” inside behaves differently. On the transparency, use a transparency pencil or pen and place dots inside the colored circles. Label them. Inside the solid, the dots will be very close together. In the liquid, they will be farther apart. Draw an arrow on each little dot. This will indicate their “sliding” ability. In the gas, draw a shape on the end of the circle to represent the end of a balloon. Draw a string on this. Students will associate a gas with air inside a balloon. These dots can have little “spinning arrows” to indicate they spin and bump. Explain to the students that the physical hoola hoop activity will be done as the drawings on this transparency. Have the students draw and label these states of matter in their science journal. When they transfer these entries to the word processing for publishing, let them experiment with different drawing and painting. Their creativity with this will translate into their participation in the game.
