Magnetic Science

Rather than a run around on the school field, Room 5 delved into a magnetic field to learn about magnets and compasses.

This links to our mathematics focus of giving and following directions and our science focus of investigating to extend our experiences and personal explanations of the physical world.

What do I know already about magnets?

They stick together, they are helpful and sometimes annoying - Skylah

They pick up certain metals and they have a North Pole and a South Pole (positive and negative) - Donald

Where can you find magnets?

The fridge, on a roof, a shop - Skylah

Fridge, whiteboards and more - Mac

Big cranes use magnets to lift heavy metal - Nick

We learned interesting vocabulary about magnets such as North Pole, South Pole, positive, negative, attract, and repel. We put some of these on our word wall. We sorted what is magnetic and what isn’t around our classroom.

We used a POE to Predict, Observe, and Explain what happened when we combined the following materials: small magnet, large needle, plastic container, water.

We had the following predictions:

I think the needle will become magnetic - Stacey

It will attract I think - Dion

The needle and magnet won’t connect - Fergus

I think it will be a floating needle - Cameron

It will break the magnet. I think it will not stick - Skylah

We had the following observations:

The magnet controlled the needle and made it move - Stacey

It started to move when you put the needle and the magnet in the water - Maraea

I saw it wiggling when I moved the magnet - Dion

The needle connects to the magnet - Fergus

It was very cool because when the magnet was in the water, you put the needle underneath and the magnet still moved - Skylah

After our observations, we rubbed the needle onto the magnet. When we put the needle into the water, it sunk. Then we decided to put it through a small cork. This made the needle float. When we rubbed the needle again, it seemed to turn in the water. We compared it to a real compass and saw that it matched the direction it was pointing. It was North.

We had the following explanations:

We can use a magnet and a needle to make a compass - Stacey

We can use a pin and magnet to make a compass - Maraea

A magnet and a needle can make a compass - Jack

The magnet connected with the pin in the water - Fergus

We can use a magnet to make a compass - Cameron

The magnet makes the needle into a compass - Skylah

It was great to see the Key Competencies of Participating and contributing and Using symbols and text in action during our science lesson.
