Fair testing!!!

 

Fair Testing Science!

Purpose- Describe what is needed in a fair test.

We watched a scientific variable video to answer a set of questions, about all the different variables you can have in a science experiment.

First there is a independent variable, in order for a experiment to be fair we can only change ONE thing.

Next there is the controlled variable, the things in the experiment that need to be the same are the controlled variables.

Then there is the Dependent variable, the things in the experiment you are trying to measure are called the Dependent variable.

 

 

We used this video clip to help us prepare for the upcoming science fair
