Directions
Observations and Conclusions
1.	Fill one or more container(s) one-half to three-
quarters full of individual types of rock and soil.
2.	Insert a straw so it nearly touches the bottom of
the container and blow. Take note of how easy or
hard it is to blow air in the straw and how gas
might travel through the soil.
3.	Record your observations.
4.	Form a conclusion about how radon, a radioactive
gas, might move up through the
5.	different types of rock and soil.

1.	Fill a beaker with water.
2.	Fill a dropper with water from the beaker.
3.	Place several drops of water on the individual types
of rock and soil. Observe whether the rock and soil
absorb the water. Permeable rocks and soil allow
liquids and gases to pass through them.
4.	Record your observations.
5.	Form a conclusion about which types of rock and
soil might slow or block radon's movement.

1.	Fill a beaker with water.
2.	Pour the water over the different types of rock and
soil in the container.
3.	Insert a straw so it nearly touches the bottom of
the container and blow. Take note of how easy or
hard it was to blow air in the straw and how the
gas might travel through the soil.
4.	Record your observations.
5.	Form a conclusion about how ground water might
impact radon's movement up through the ground.
