                                        An Aimsir/ Weather

This week the weather has been very cold with a lot of snow all over the country. We decided to do some experiments as follows.

 

 

Does water and Sprite both freeze at the same temperature?

 

You will need:

2 matching measuring beakers

2 Thermometers

Sprite

Water

 

What to do:

Pour 50mls of water into one of the beakers.

Pour 50mls of Sprite into the other beaker.

Place a thermometer in each beaker and place both beakers outside overnight.

 

 

 

 

Results:

The following morning we checked the two beakers.

All the water was frozen solid.

The Sprite was still in liquid form although the temperature had dropped below 0.

 

Experiment 2

To demonstrate that salt water has a lower freezing point than water.

You will need:

4 matching measuring beakers

Salt

A teaspoon

 

 

Checking the ground temperature
