Seed that have been exposed to a Cobalt-60 source are used to demonstrate the effects of varying degrees of radiation. Squash preparations of root tips show distinct disturbances of the normal mitotic pattern. Somatic changes brought on by irradiation are often clearly visible a short time after germination begins. The set contains an untreated control packet and packet of seed exposed to various levels of radiation (50; 150; 500; 4,000 Krads). At least 50 marigold seeds per packet.

Rated 4 out of 5 by from Good overall 1) A few of the seed group results showed growth in groups that should not grow or vice versa: evidence that the seed packets may be mislabeled or that the seed contents were switched during the packaging process. These results can bring up an opportunity to question students about the cause of such results. 2) In the past, I have advocated adding a few seed groups between the middle dose (500 krads) and the extreme dose of 4000 krads.
