13. 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.

14. Color Code Alpha Rock – Red Beta Rock – Orange Gamma Rock – Silver

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.

16. 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- ProtonsWhite 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 e - Gamma 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.
