Experiments

Testable Question: Do plants grow taller under a green, red, blue, or natural sunlight?

Can be turned into a hypothesis…

IF_______________________, then

______________________________.

Hypothesis• A prediction that answers the question in an

experiment.

• Testable Question: Do plants grow taller under a green, red, blue, or natural sunlight?

Can be turned into a hypothesis…

If I place plants under green, red, blue, and natural sunlight , then the plant under the red light will grow faster.

Variables and Controls

Independent Variable: Something the scientist changes during the investigation.

Dependent Variable: Something that changes and can be measured as a result of the independent variable.

Control/Constant: Something that stays the same in an investigation.

Variables

Jane Goodall began studying Chimpanzee’s in the 1960’s. Jane moved to Africa and began making close observations of Chimpanzees in the wild and in captivity. Because of her investigations we now know that chimpanzees are meat eaters, use tools, and hunt Capuchin monkeys for food.

Max wants to help plant the school garden. He is interested in planting species of plants and flowers that will attract birds and butterflies. Max decided to go to the local city garden. Max made careful note of the animals that visited the gardens. When he was finished observing he recorded the names of the plant species that were planted there.

Jason is on the track team, and he wants to run faster. While watching TV, he sees two different commercials for energy drinks that promise to give you more energy. He times himself running 1 mile on Monday without any energy drink. Then he times himself running 1 mile after drinking 16oz of Red-Bull one week later. Finally, he times himself running 1 mile after drinking 16oz of Monster energy drink a week later. After analyzing the data, he infers that energy drinks do not make him run faster.

Mark works for the National Forest Service. He is concerned about the effects of forest fires on the species plants and animals in the mountains where he works. Mark decided to visit the north side of Sleeping Ute Mountain where fires were very rare. He recorded observations of the plants and animals. Mark then traveled to the south side of the mountain that had recently experienced a wild fire (cause by lightening). Mark recorded his observations of the plants and animals there.
