Fair Test Fails!

Mrs Tatman has clearly had an exhausting week! She tried to come up with ways to explore investigation questions this afternoon, but seemed to get in a complete muddle!

        

Do girls skip faster than boys? Why wasn't this a fair test?

             

Can taller people drink more quickly? Was this a fair test? Why?

                 

What was wrong here? What did you decide would make it a fair test?

                                     

Which ball will bounce the highest?

                

                              

We then thought of ways to answer Mrs Tatman's final question.

                      

What did you decide?
