  2. The Scientists:

A researcher is developing a treatment for cancer.

Problem: ______

She looks at the results of previous treatments and sees what didn’t work.

Research: ______

A cream is produced to apply to the tumor

Hypothesis: ______

She gets three patients with similar cancer and applies the cream

Experiment: ______

She measures the tumor over four weeks and records her data.

Observation: ______

From the data, she notices a significant decrease in the size of the tumor

Conclusion: ______

She believes the cream caused the tumor to shrink

Accept/Reject/Change Hypothesis: ______

She shares her findings with pharmaceutical companies so the cream can be made available to a larger population of cancer patients.

Communicate: ______

  1. The Average Person:

A student walks into the cafeteria and needs to buy a lunch

Problem: ______

He looks at the choice that are offered

Research: ______

The student picks the meatball surprise

Hypothesis: ______

Communicate: ______

  1. Experimental Design:
  2. Scientists use experiments to determine cause and affect relationships in nature. They design an experiment so that changes to one item cause something else to vary in a predictable way. These changing quantities are called variables. And experiment has two kinds of variables: independent (manipulative) and dependent (responding).
  1. Independent (manipulative) variable ______. There can only be ______independent variable in an experiment.
  2. Example:
  3. Dependent (responding) variable ______
  4. Example:
  5. Constants are parts of the experiments that ______throughout the experiment.
  6. Examples:
  7. Control: A base experiment that uses the standard conditions ______
  8. Fill in the chart below

Vocab Word / Definition / Associations
Variables
Independent Variable
Dependent Variable
Controls
  1. Most experiments can be set up in the format:
  1. Write a hypothesis for the following variables.
  2. IV- sunlight, DV- plant growth
  1. IV- exercise, DV- heart rate
  1. In the chart below, the first blank represents the Independent Variable and the second blank represents the Dependent Variable. Controls are the things in the experiment that must be kept the same so you that you are only testing one variable at a time in the experiments. See the examples below

Question / Independent variable / Dependent variable / Controls
How does the amount of fertilizer affect the plant growth? / Amount of fertilizer / Plant growth / Type of plant
Amount of soil
Amount of sun
