The Effect of Polonium-210, Strontium-90, and...

Project by group pbchsbartenslagerspring2020

Explore Pea plants grow an average of 3 feet. Water plants once a week and never let soil become dry.
Research Question We want to test if the radiation will help the pea plants grow more than the pea plant control group. We decided to use radiation because our research said that UV-C radiation would help boost the growth by altering the genetic material. We are testing to see if these other types of radiation will have the same effect.
Predictions It is predicted that Strontium-90 will make the pea plants grow the most because it has the longest half-life (28.8 years), then Cobalt-60 (5.26 years), then Polonium-210 (138 days). The control group will grow the least because it has no external factors helping it grow.
Experimental Design IV- different types of radiation (polonium-210, strontium-90, cobalt-60) DV- how much the pea plants grow after 1 month and a half and when they germinate constants- classroom conditions, amount of water,amount of sunlight Label each group (group 1-3 and control) using pea plants. There will be 30 pea plants in each group. Groups 1-3 get 3 different types of radiation. Put the radiation disks in the middle of each group and keep them separated so that the disks don't affect other groups. Water pea plants deeply once a week so the soil is never dry. Seeds should sprout in 7-14 days. Mark down when each seed sprouts and germinates. Measure the growth of all groups every 2 days and count the leaves. Continue to record observations for one months and a half. After one months and a half, dig up each group and measure root hairs.
