Activity
Pretend you have been given 3
radioactive rocks; 1 alpha, 1beta and
1 gamma. You can get rid of one rock,
pocket another and hold the last one.
Which would you throw away?
Pocket? Hold? Turn to your neighbor
and discuss the answer to this
question.You have three (3) minutes.
Color Code
Alpha Rock – Red
Beta Rock – Orange
Gamma Rock – Silver

There are three forms of radiation. Alpha radiation cannot penetrate solid surfaces and causes the
least amount of damage to the body. Beta radiation can pass through light surfaces and can harm body
cells. Gamma radiation can pass through most solid surfaces and damages body cells.
Create your own radiation
Using only the materials in the beaker, you are to create atoms
and demonstrate them going through all three types of radioactive
decay. Keep all materials on the placemat provided.
In the center nucleus:
Red Legos- Protons
White Legos- Neutrons
Yellow Legos- Gamma rays
Beans- Electrons (e-)
Use the periodic table to determine # of protons, electrons,
neutrons.
Make elements 1-10 with each going through:
Alpha decay- remove 2 protons, 2 neutrons
Beta decay- remove one neutron, add a proton, give off an eGamma decay- give off gamma ray-no change in mass
Demonstrate to another student this process, obtain a signature
for all 10 atoms going through all three forms of radiation.
