HOW TO TACKLE RELIABILITY QUESTIONS?

HOW TO TACKLE RELIABILITY QUESTIONS?

To ensure reliability, the experiment needs to be conducted at least 3 times until the results are consistent.  In this article I will share with you two question samples on how to tackle questions involving the reliability of the experiment by using "3 RE" Strategy (REliable- REsults-REpeat). (i)   Why do we repeat experiments a few more times? If you conduct an experiment just once, you could get an anomalous (uncertain) result.So, when we repeat the experiments and find the average of at least 3 sets of consistent data, the results collected will be more reliable.  (ii)   Reliability question is often expressed in the following format: Variant 1: Why is there a need to repeat the experiment a few...

HOW TO TACKLE CONTROL SET-UP QUESTIONS

Control Set-up Questions

Experimental-based questions are regularly tested in Primary School Science examinations.
In this article I will share with you three question samples on how to tackle control set-up questions by using "3C" method (Control-Compare-Confirm).
