Can there be 2 experimental groups?

Can there be 2 experimental groups?

The experimental group is the set of subjects exposed to a change in the independent variable. It’s possible for an experiment to contain more than one experimental group. However, in the cleanest experiments, only one variable is changed.

What do you need to observe to develop a good experimental research design?

• Step 1: Define your research question and variables. You should begin with a specific research question in mind.
• Step 2: Write your hypothesis.
• Step 3: Design your experimental treatments.
• Step 4: Assign your subjects to treatment groups.

How do you do light experiments?

Instructions

1. Get a sheet of paper, and draw two arrows on it. One arrow near the top and one arrow near the bottom. Make the arrows point in the same direction.
2. Fill a glass with water.
3. Slowly lower the piece of paper behind the glass of water.
4. Look through the glass of water and watch what happens.

Why do images flip in water?

Refraction is the bending of light. In addition, the water acts as a magnifying glass, which bends the light toward the center. The light comes together at the focal point and beyond the focal point the image looks reversed because the light that was on the right is now on the left, and vice versa.
