Time Frame
1 class periods of 60 minutes each
Summary
Students will grow radishes and experiment with the critical amount of water that they need to survive.
Materials
Background for Teachers
Time Needed: 50 minutes for the set up and 10 minutes daily for observations and follow up during the next 2-3 weeks.
Instructional Procedures
Procedures for application lab (A):
- You may wish to sprout the radishes ahead of time or allow the students to do that. The seeds need to be kept wet for several days on a paper towel or soil mixture to germinate.
- Students should work in groups and each group will grow three seeds in the varying amounts of water.
- Students should write their observations and when the results become clear, the experiment should be ended.
- Compare the results from each group. Hopefully, enough groups will agree to the amount needed for radish growth to draw a conclusion.
- Allow time for students to complete the analysis and conclusions.
Procedures for inquiry lab (B):
- You may wish to sprout the radishes ahead of time or allow the students to do that. The seeds need to be kept wet for several days on a paper towel or soil mixture to germinate.
- Read the introduction with students and allow time for them to develop a question related to what limits the growth of radishes. You may wish to have them put their question on a white board and share and discuss them with the class.
- Students may use a variety of materials that you can supply or they may bring things from home also.
- Allow time for set-up of the lab and follow-up observations. Students can make observations for as long as changes keep occurring.
- Have each group present their findings before the analysis questions are answered.
