Fair testing

Angela wanted to find out if radish seeds would sprout if she watered them every day about as much as it
rains usually. "I think the seeds will not germinate if I water them too much." She thought to herself "/
wonder what experiment I could do to find out the answer and make sure it's a fair test?"
Angela bought a packet of radish seeds and then collected some containers and some garden soil from
her father's garden shed. She decided that she would test two different amounts of water to see which
amount made the seeds germinate/sprout quicker. Angela worked out that she needed 500ml a day to
keep the soil moist in her containers. So, she decided she would use 500mL in containers marked sample
A and 250mL in the containers marked sample B.
