S, L, G Stations
Third grade Chemistry lesson

Liaison: Sadhna Vora
Date: 03/02/99
Group Members: Mary-Beth Muchmore and Julie Kalos
School: Tobin
Teacher: Mrs. Burgess

Materials:

various samples for stations; we chose:
Stations:
1. toothpaste
2. efferdent in water
3. water
4. cornstarch
5. oobleck
6. balloon—blown up
7. jello/last week’s slime
8. soda
9. poster gum
10. moisturizer
11. cotton
12. bar of soap
13. rock

Procedure:

1. Finish up talking about last week and the slime handout. Have them answer the question
at the bottom. Also, make nametags again. (5 min)
2. Pass out sheet and talk briefly about what they think solids, liquids, and gases are.
Have them fill out the chart as best they can with general characteristics. (i.e.,
solids are hard, can’t be smushed; liquids have fixed volume, but move and conform to the
shape of their container; gases spread out, and just b/c you can’t see them doesn’t mean
they’re not there (5 min)
3. Break class in half. One half will do demo with moving around as the atoms in solids,
liquids and gases (talk briefly about converting between states of matter: add heat; talk
about ice melting). Other half will do the stations, defined as above.

Handout:

Solids, Liquids, and Gases

Last week we talked about slime, and how it was like both solids and liquids. Today we
will talk about other examples of solids, liquids, and gases. The questions we want to
answer today are: How do you define solids, liquids, and gases? What makes them different
from each other?

Part 1: Write down what you think makes solids, liquids, and gases different from each
other.

Solids Liquids Gase
