Cheap plants in three even groups
Three similar sized containers
A ready supply of water
A modern microwave
A ruler
Measuring cup
Record book
After the all the equipment is bought, the first step to replicate this experiment is to place the three plant group in each of the containers, filling the container to around three quarters of the way up, not covering the plant. In my case the plants I used were spinach sprouts, with two sprouts in each ice-cream container. A good idea I wasn’t aware of during my experiment is to poke holes in the bottom of the container and put them in larger containers to catch any excess water. Once the main part of the experiment is set up, use your record book to draw a table. This table will be the key to a successful result and a reference point to make any findings on. A simple table is all that is required until you can present it. It should have 4 columns and 11 rows, one row for each day of the experiment and an extra for the identifier of the plants. For the purpose of simplicity the plants are named a, b, and c. Now you must choose which plants will be exposed to what. Note: you must keep a control sample to see how the plant would grow without the radiation. My choices were as following: •A: Control sample

B: Exposed to radiation directly
C: exposed to radiation indirectly
Once labelled, you can begin the cycle that must be repeated every day for the next 10 days. First will be sample a, the control. Nothing else should be done but watering the plant exactly 15ml, this is where the measuring cup should come in handy. Now is sample b, which will be directly exposed to radiation. Heat it in the microwave for 30 seconds, wait 5 minutes, then water with 15ml. lastly is sample c, to be indirectly exposed to the electromagnetic radiation. Heat 15ml of water in the microwave for 30 seconds, pouring on sample c immediately after heating. With the plants tended to, you must...
