Children are born scientists – they are innately curious about the physical environment and naturally open to making meaning through their exploration and conversations with others. Science teaching and learning has a place in all early learning services.

Children are born scientists – they are innately curious about the physical environment and naturally open to making meaning through their exploration and conversations with others. Science teaching and learning has a place in all early learning services.
Science teaching and learning is about introducing children to the ways scientists think about and investigate the physical environment. Scientists do this in two ways.
They explore and confirm ideas about the physical environment we live in through investigation and exploration.
They form hypotheses or “working theories” to make sense of the physical environment and identify these as science knowledge.

What We Did

Room 12 explored how water pressure works.

Introducing the Resources

We needed

2L empty plastic bottles
Straws
Hot glue gun
Water and food colouring
Balloons

Modeling the Process - Part 1

I made a small hole in the bottle.
A straw was inserted so most of it stuck out.
It was sealed with a hot glue gun

It will shoot out of the straw.

Introducing Scientific Thinking - Part 1

Predictions - We thought about what would happen when we filled the bottle with coloured water.
Hypothesis - the water would flow out of the straw.

Modeling the Process - Part 2

We filed the bottle with water

Introducing Scientific Thinking - Part 2

We observed that the water stayed in the bottle and did not flow out of the straw.

Maybe we should shake the bottle.

What would happen if I blow up a balloon and fix it over the top of the bottle?
Hypothesis - the water would flow out of the straw.

Why?

The air is pushing the water out.

The students now know scientists predict, observe and record.
