what is step two of the scientific method
What is propose a hypothesis
100
After making a testable question and a hypothesis, this should be done before doing the experiment.
What is plan an investigation
100
These would be the parts of the lab that never change in the experiment.
What are the control variables?
100
An investigation was done to see if keeping the lights on for different amount of time each day affected the number of eggs the chicken lay.
Independent: The time each day Dependent: Number of eggs laid.
200
This is used to measure meters
What is a meter stick
200
what is another way to say hypothesis
What is and educated guess
200
After recording data onto a table, you should always find a visual way of representing the experiment. This visual uses the X and Y axis.
What is a graph.
200
there is only 1 of these in an experiment and it ask: What are we changing in the experiment?
What is the independent variable?
200
The time it takes to run a mile depends of the amount of exercise a person gets.
Independent: The amount of exercise. Dependent: The time it takes to run a mile.
300
This is how you measured liquids in your 4th experiment
What is milliliters
300
When writing a hypothesis, looking after the word IF in an IF, THEN, BECAUSE statement will let you know which variable this is.
What is the independent variable.
300
When using an experiment involving measurement this should always be the first measurement to show change.
What is initial mass?
300
There is only one of these in the experiment and it ask: What are we measuring in the experiment?
What is dependent variable?
300
Five groups of rates are fed identical diets except for the amount of cheese that they receive. Each group gets a different amount. After 3 weeks on the diet, the rats are weighed to see if the amount of cheese received has affected their weight
Independent: The amount of cheese Dependent: weight of the rats
400
When making a graph, this is what the X axis will have
What is the independent variable?
400
This is what you are measuring in the experiment.
What is the dependent variable?
400
This is the part of the experiment where you ask "What could you change in the experiment?" It is usually at the end of an experiment.
What is a conclusion
400
what is the dependent variable
What is the variable that changes based upon the independent variable.
400
Students in science class carried out an investigation in which a flashlight was pointed at a screen. They wanted to find out if the distance from the light to the screen had any affect on the size of the illuminated area.
Independent: The distance Dependent: The size of the illuminated area.
500
This would be the X axis, the Y axis, a title, a unit of measurement on the x axis and a unit of measurement on the y axis
What is the 5 parts of a good graph.
500
what key words must you have in your hypothesis
What is if then and because
500
This would be what you are changing in the experiment.
What is the independent variable.
500
what is the variable that stays the same throughout the experiment and there can be more than one.
What is the controlled variable
