Variable | anything in an experiment that you can change that might effect the outcome |
Independent Variable | Variable that is changed by the experimenter |
Dependent Variable | Variable that will change due to the independent variable changing |
Constant Variable | Variable that is controlled not change |
Controlled Experiment | When one variable is change |
Standard | Basic procedure used in a controlled experiment, before changing any variables |
Capacity | Greatest amount of fluid a container will hold |
Density | amount of matter that will fit in a given space |
Archimedes | Used displaced waterto reveal characteristics |
Galileo | First to propose that pendulums could keep track of time |
Wright Brothers | Invented and flew the first plane |
Bessie Coleman | First black woman to get her pilots license |
Chuck Yeager | first pilot to break a sound barrier |
List the steps of the scientific method | 1.Ask a question 2.Form a hypothesis 3.Design experiment 4.Analyze results 5.Draw conclusion |
What variables were tested in the pendulum system | Length of string, drop height, mass of pendulum bob |
What is the relationship between the length of string and the number of cycles a pendulum makes | The longer the string the less swings |
What variables affect how many pass. can fit in a boat in the boat experiment | Capacity of boat, condition of water, and placement of pennies |
what is the relationship between the capacity of the boat and the # to sink a boat | Greater capacity the greater the pennies |
What is the relationship between the mass of the plane and the distance it can fly | The more mass the less distance |
Explain what determinds weather an object will sink or flat |
