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.
