Spark the children’s interest by showing the picture of a bike with a flat tire. Ask this question: “What do you know about a bike and a flat tire?" Record their responses on a smartboard or whiteboard. Ask the students for evidence that supports their responses. This should lead into a conversation that connects the contribution of the tire to working bicycle.
Once the students come to this realization, then show them a plant that has a missing part. Let them tell you what they know about this plant. Divide the students into groups of two and give them time to brainstorm how the plant would be effected with a missing part. The students should work together to record responses and evidence to support their thinking on the dry erase boards.
When finished, each group should go to the Class Graph and color in the appropriate box that matches their missing plant part. Pull the students back together and allow each group to share their thoughts. Record answers on the smartboard or whiteboard. This activity entire activitiy should take about 20 minutes.
Assessment: During the investigation, the teacher will monitor to see if the students are able to understand and demonstrate that the missing part might change its structure, its ability to get what it needs, or even cause it to die. Overall, they should be able to recognize that all of the parts are needed to complete the plant.
Students love working together. It provides support for those students who need it and it also allows those more confident to assume a leadership role. When students work together they are able to share a wealth of knowlege with each other. In this activity the students should be able to work together to figure out what part of the plant is missing and draw conclusions about how the plant will be affected.
