Independent variable/Manipulative variable
What is the variable you (the scientist) intentionally change?
100
The first step in the scientific method
What is Identify the problem?
100
These are things that remain the same in an experiment.
What are constants?
100
Changeable elements of an experiment which can affect the outcome of the experiment.
What is an independent variable?
100
This is a technique used by scientists to answer questions
What is the scientific method?
200
Constant
What are things that are kept the same?
200
The third step in the scientific method
What is form a Hypothesis?
200
This is the normal group in an experiment and is used to compare the results too.
What is the control group.
200
The number of variables that should be allowed to change in a well designed, controlled experiment.
What is one?
200
This is something that has been supported by lots and lots of research and fact and is probably always going to occur (hint: evolution)
What is a theory?
300
The variable you observe changes in (what the experiment is about)
What is the dependent variable or experimental variable?
300
The fifth step in the scientific method
What is make Observations?
300
This is a statement that is used as a prediction before an experiment.
What is a hypothesis?
300
The______________ variable is the variable you are observing and that changes in response to the ______________variable.
What is the dependent variable and independent variable?
300
To gather information using your senses
What is to observe or to make an observation?
400
The dependent variable in an experiment testing the effects of fertilizer on plant growth.
What is plant height? The scientist was testing to see if fertilizer affects plant growth
400
The final step in the scientific method
What is Communicate your results?
400
This is a prediction based on your senses and opinions.
What is an inference?
400
Four groups of rats are first massed and then fed identical diets except for the amount of vitamin A they receive. Each group gets a different amount. After 3 weeks on the diet, the rats’ masses are measured again to see if there has been a decrease. What is the IV, DV, constants, and a control group.
IV- Vitamin A DV- Mass of mouse CO- type of mice, diet, health CG- Mice with normal food
400
This is the first thing you should do before preforming an experiment
What is read all of the directions?
500
The independent variable in Mr. Krabbs' Krabby patty experiment
What is the type of sauce used? Mr. Krabbs was testing to see if his new special sauce would help reduce the gas problems in town.
500
This is the step where you will most likely have a table and/or graph
What is the 5th and 6th steps, make Observations and draw Conclusions?
500
This is when you make a prediction about data outside a graph. This is when you make a predicition about data inside a graph.
What is extrapolation? What is interpolation?

Lisa is working on a science project. Her task is to answer the question: "Does Rogooti (which is a commercial hair product) affect the speed of hair growth". Her family is willing to volunteer for the experiment. Explain how she will do this.
She will have to first measure the hair growth before using the shampoo, then measure it after using the shampoo.

Explain and name the process used to find the volume of an irregularly shaped object.
What is Liquid Displacement? Take an initial volume of a graduated cylinder, place an object in the graduated cylinder and take the final volume. Subtract the initial volume from the final volume, then convert to cubic centimeters.
