| Hypothesis | I think a pendulum will take longer to complete one swing if the string is made longer |
| Dependant Variable | The class built several paper airplane designs and then threw them to see which went the farthest. We then measured the distance flown by each airplane. The distance the airplanes flew would be an example of... |
| Controls | If you are testing whether the length of a pendulum determines the time it takes to swing, you must keep the weight and position of the pendulum always the same. The weight and position would be examples of experimental... |
| North and South | magnetic poles that attract each other |
| Gravity and magnetism | cannot attract and repel |
| Neptune | Planet that feels the least pull of gravity |
| Length | the variable that caused the period of the pendulum to increase |
| Steel, Nickel and Cobalt | materials that are attracted to a magnet |
| Poles | strongest part of the magnet |
| Weaker | as maganets move farther away the force gets |
| Less Bright | IN the light lab, as light got farther away from the board, the brightness became |
| Larger | In the Inverse square light lab, as the light got farther away fromthe board, the area of brightness became |
| Trials | number of times we take each piece of data |
| Procedure | the typical design of an experiment with a detailed list of step by step instructions |
| Analysis | use of math, charts or graph to see how data answers the original purpose |
| Conclusion | a specific statement about what you found out about the hypothesis |
| Purpose | the thing you wanted to find out in the experiment |
| Independent Variable | part of the experiment that we change |
| dependent variable | what we are trying to measure |
| scientific method | an orderly method of gaining, organizing and applying new knowledge |
| pseudo science | information given based on unreliable observation, one time occurrences, not found to be repeatable |
