Friction

This afternoon we have tested the effects of friction. We wanted to see which surface had the least amount of friction on for walking. We tested 5 different surfaces: wooden floor, grass, concrete, tarmac, laminate and carpet.

Which surface do you think will have the least amount of friction?

Testing water resistance

This afternoon in science we tested whether or not our boats would float. In teams we worked together to create our boats , using plastic bottles, and other  materials. Most of our boats floated but one which had holes in the bottle started to sink. So as a class we discussed how we could improve the boat and came up with the solution of covering up the holes, which would help the boat float as no water could get inside.

Whats the best material to make a boat with?

Testing Water Resistance

This afternoon, we have been busy designing a boat. We have learnt about the different types of forces that are affected within water resistance. Water resistance slows objects down when they are trying to move through the water.

We have designed this boat because it is light so it will float and it is streamlined so it will glide in the water.

Planting

This afternoon, we have visited our greenhouse. We used Slido to make predictions on which plant is going to grow the quickest, ready for our plant sale.

Which plant do you think is going to grow the quickest?

The direction that different forces act

This afternoon, we have tested how air resistance acts upon a force. We have learnt that as an aeroplane files through the sky, it has to push through the air around it. Friction between the air and the plane slows the plane down, which is known as air resistance.

We tested our paper aeroplane designs and measured which aeroplane travelled the furthest.

Coding Earth and Space

This afternoon, we have learnt how to code different shapes. We linked it to our earth and space topic. We changed the sprite to a planet and chose an appropriate space themed background.

Did you know that the earth orbits the sun?

Australian Aboriginal journey sticks

This afternoon, we have been creating journey sticks. This week in literacy, we have focused on autobiographies. Today, we story mapped our plan, focusing on the key events in our lives. This afternoon, we spent creating a journey stick of our life so far.

What would you include in your journey stick?

Reversible or irreversible changes

This afternoon, we were investigating the difference between irreversible and reversible changes. Reversible means being able to form its shape again and irreversible means its the change cannot be undone.

We carried out a experiment using a variety of different food types: toffee, potato, chocolate, eggs and butter. We had to decide whether these types of food where reversible or irreversible.

Can you think of any more food types that may be reversible?

Science week

Starting this weeks science week, we were investigating which material would be the best insulator. We were testing out different materials for a new lunchbox lining. We found that plastic was the best material because it kept the ice-cube the coldest for the longest. We tested fabric and foil too.

Which material would you have predicted?

Farming award

This afternoon, we have been busy building on our knowledge and skills in order to complete the farming award. Focusing on the principles of plant growth.

Do you know the main principles for plant growth?
