SCIENCE - FAIR TESTING

In science, we are inquiring into how solids, liquid and gases can change.   

As part of our inquiry, we have decided to test five different liquids.  Cooking oil, sea water, tap water, white vinegar and milk.  In our first investigation we are trying to answer: Which liquid evaporates the quickest?

To do this we got some of each liquid in five different containers and planned to measure the liquids level each week. 

As a whole class we learnt about fair tests and why we need to make the test fair.  To test these fairly we thought we needed to :

• Have the same size containers.
• Have the same amount of liquid.
• Measure the same each time.

We now want to answer these questions in our next Science Investigations:

• Which liquid makes the biggest puddle?
• Which liquid will boil first?
• Which liquids will freeze?
• Which liquid will boil first?
• Which liquids has the coldest/hottest 'little lumps' (molecules).
