Know the Following

STUDY GUIDE SCIENCE TEST

Know the following:

 What is a variable? o Listing variables in an experiment

 What is a controlled experiment? o Changing one variable and testing how it affects your experiment

 How does a variable affect: o Pendulum system o Lifeboat experiment o Flipper system o Flight of FOSS plane (all experiments were done in class)

 Characteristics of a controlled experiment o Example: What affect do the size of the back wheels and the shape of the front end of a model race car have on the speed of the car? . Wheels: big and small . Front End: round or pointed

 Catapult system o Parts of a catapult system o What things might you do to a catapult system to make an object go higher or farther?

 Independent and Dependent variables

 The affect mass has on the distance a FOSS plane can fly

 Relationship between the length of a string and the number of swings a pendulum makes

 Graphing data from a “T chart”

o Predicting outcomes using a graph
