Other seeds are dormant because certain slow chemical reactions must take place within them before they are ready to germinate. In this chapter, you will watch seeds germinate and investigate factors that affect germination. 1 Watching Seeds Germinate Materials: paper towels seeds (lima bean, corn, squash, pea, and others) large, clear drinking glass newspaper water You can watch seeds in a glass germinate in much the same way that they would in soil. Line the walls of a large drinking glass with several paper towels as shown in Figure 2.
In which soils do the seeds germinate? In which soil do the seeds germinate first? In those soils where seeds germinate, continue to water the growing plants with equal amounts of water. In which soils do the seedlings grow into mature plants? Measure the heights and count the leaves on the plants in the various soils every other day until they mature (produce flowers). Record your data in your science notebook. Compare the growth rates and the number of leaves on the plants in the different soils.
That means there are two groups treated exactly the same except for the single factor that you are testing. Any factor that can affect the outcome of an experiment is a variable. In a controlled experiment, all variables are kept the same except for the one the experimenter wants to investigate. For example, if you want to investigate whether green plants need light to grow, two groups may be used. One group is called the control group, and the other is called the experimental group. The two groups of plants should be treated exactly the same: They should receive the same amount and type of soil and water, be kept at the same temperature, and so forth.
