Variation is the fuel for Natural Selection. Without a variation of a trait within a population there can be no change....
When there is a variation of traits within a population, it is likely that some variations will be more helpful in surviving.
You will investigate two variations among peanuts
- length of shell
- number of seeds per shell.
50 peanuts in shells, metric ruler, pencil, data table, graph paper
- Count out 50 peanuts in their shells.
- Use a metric ruler to measure the length of each shell in millimeters. Put a check mark in Table 1 in the space indicating the length of the shell.
- Open the shell and count the number of seeds inside. Put a check mark in Table 2 in the space next to the number of seeds that you counted.
- Repeat steps 1 - 3 for the other 49 peanuts.
- Set up two bar graphs
using the headings from each table
as the axes for each graph.
- Plot a bar graph from the data in each table.
