Science Presentations

In Term 2, Room 8 had to choose a topic to do with forces, (flight, buoyancy, wind, friction etc.) and demonstrate an experiment with a buddy or by themselves…

The topics Room 8 had to choose from were:

- Wheels.

- Cogs.

- Planes and flying.

- Electricity.

- Magnets and magnetism.

- Wind.

- Sound.

- Buoyancy.

- Cars, trucks, motorbikes etc.

- Friction.

- Toys.

- Forces we can see, and forces we cannot see.

Before we demonstrated our presentation, we had to learn about our topics, and all forces.

For example, we had to learn why wheels had cogs, and match the parts of a bike to it's correct place…

Some of Room 8 had to do it in their own time, because the experiment wouldn't have worked if we didn't have the right equipment.

Here are some photo's of the great presentations students in Room 8 did…

FRICTION - Macy, Sophie, Sam B.

FRICTION - Sophie, Macy.

FRICTION - Brylee, Kaleb.

TOYS - Sara, Maria.

BUOYANCY - Paul, Shayla, Becky, Cassie, Sorraya.

BUOYANCY - Eggs.

MAGNETISM - Alisha.

TOYS - Sara.

TOYS - Sam.

FRICTION - Jordan, Lily.

Room 8 have been looking at forces for Inquiry in Term 2 and we found and experiment to do with a force which was flight, it was called a Balloon Rocket.

The three questions we had to find out about were:

- What makes the rocket go slower?
- What makes the rocket go faster?
- How could you measure the speed?

We found out that by cutting the straw it made it go slower…
So therefore, having a longer straw would make it go faster.
We used a timer, but we figured that you could also use a phone,
computer or anything with a timer on it.

Everybody in Room 8 thoroughly enjoyed doing this experiment, and it was a fun way to learn about flight.

Here are some photo's of Room 8 doing the experiment…
