Gases-Expanding Possibilities

      Expanding possibilities:

WALT:write a procedural text in the form of experiment?

This activity is trying to see how increasing pressure affect gases.

                Hypothesis:

When we pour hot water at the end of the bottle it will create  bubbles.

Materials:

• bottle
• plastic container
• glass jug
• bowl
• straw
• blue tack
• litre jug

 

Method:

1. Put the  straw in the bottle so the flexible end is sticking out.

2.Fill a cup about ¾ full water.

3.Hold the bottle near the top end while a partner pours hot water over the bottom end of the bottle.

4.Watch the end of the straw in the water.

Conclusion:

We have proved that when there is  increase pressure by warning the air inside the bottle affects gases.It produces bubbles.
