Use the rose experiment to answer the question. what are the independent and dependent variables? (site 1)

List what you know about plant growth.

How the Independent Variable of Light affect the Dependent Variable of Plant Growth  

Independent Variable- Amount of Light; Dependent Variable- Plant Growth; Controlled Variables- temperature, humidity, container, soil

1. Plants need light to grow. Learn more about photosynthesis and chlorophyll

What effect does the amount of light have on the growth of a plant?

Note that the question identifies two variables: amount of light and growth of a plant.

Note that both variables are changed. You control the change in the amount of light and

you will be observing how the change in light affects the growth of a plant.

Note that both variables are measurable.

Cause-Independent Variable: amount of light

Effect- Dependent Variable: growth of plant

2. Plants have stems that grow upward and roots that grow downward. Learn more about geotropism.

What effect does the angle of growing medium have on the direction of plant stem and root growth?

3. Plants have green leaves because of the presence of chlorophyll. Learn more about chlorophyll and other plant pigments.

some scientists like gregory adcock agree with thorne's theory of regional continuity.

others, like chris stringer and ian tattersall, believe thorne's results may be contaminated or misinterpreted.
