Because the two groups were treated exactly alike except for light, increased growth of plants kept in the light would allow you to conclude with confidence that more growth is a result of the one thing that was different: the availability of light. Two other terms that are often used in scientific experiments are dependent and independent variables. The dependent variable here is growth, because it is the one you measure as an outcome. Light is the independent variable; it is the one the experimenter intentionally changes.

The dandelion seeds will detach themselves from their parachutes and develop into seedlings. Observe your seedlings as they grow, and be sure to keep the lint or paper towels moist. Write your observations in your science notebook, noting the time and date and a description of what you see. FIGURE 4: A dandelion plant has airborne seeds.

In a field of uncut grass, the dandelion will have a long stalk.

Science is much more than that. Science is the study of the things that are all around you, every day. No matter where you are or what you are doing, scientific principles are at work. You don’t need special materials or equipment to be a scientist. Materials commonly found in your home, at school, or at a local store will allow you to become a scientist and pursue an area of interest. By making careful observations and asking questions about how things work, you can begin to design experiments to investigate a variety of questions.
