Experimental Investigations Review

Angelina set up an experiment to see how the mass of a ball affects the distance it rolls off a ramp. Identify the independent variable.

• Distance traveled by the ball

• Height of the ramp

• Mass of the ball

• Who set up the experiment (Ms. S, etc)

Kreedence wants to know if birds prefer to eat in one place over another. She makes three feeders out of 2-liter bottles and paints all of them red. She fills each of the feeders with the same amount of mixed birdseed, and plans to keep the feeders out for 10 days before measuring how much seed is eaten from each feeder. She puts each of the feeders in her back yard: one feeder in a large dead tree, another feeder she sits on the dog house, and the last she sits in a small bushy tree.
What is the dependent variable?

• Length of the birdfeeders

• Amount of time feeders are outside

• Amount of seed eaten

• Location the feeders are put in.

The part of the experiment that does not contain the independent variable. Used for comparison.

• Control Group

• Experimental Group

• Results

• Data

2 ways that scientific investigations can be retested are:

• measurement and control

• repetition and replication

• defining a problem and hypothesizing

• concluding and analyzing
