Arcadia

Well the big day finally arrived and the hall was packed with arcade games made from recycled boxes and materials. The Year 3/4 students hosted the Preps and Year 1 students, demonstrating how each game worked, talking about the forces involved and letting the younger students play. The whole hall buzzed with excitement as the students explored so many fantastic games.

Magnets, Gravity and showing our learning.

We created ‘floating paperclips’ to explore the size and direction of the force associated with magnets and gravity. As part of the ‘explain’ session of our unit on forces we had to create a simple role play that used small and large labelled arrows to show the direction and size of the different forces. We had lots of discussion about what forces were actually involved.

To bring all our learning about forces together we are preparing for ‘arcadia’. Using ‘Caine’s Arcade’ as our inspiration the Year 3/4 students are working in groups to create arcade games. Each group has to design their arcade game, explain the forces at work in it, create a prototype and finally build the game. They have been amazingly creative with their ideas and found that some things needed to be changed during the building of the prototypes.

Friction from different surfaces

Now it was time to investigate the effect of different surfaces on friction. We tested concrete, carpet and the table. We all agreed that concrete gave the most friction (we needed more force to push the box) but that the table and carpet were very similar. We had lots of discussion about why they might be the same.

There’s a fraction too much friction!

Our next exploration into force was to investigate friction. To get the students thinking about friction we played ‘tug of war’ all in the name of science! We had to observe the pull forces and the movement of the rope with the forces. Next we put on gloves to see what difference it made to the pull forces. When we added detergent to the gloves there was less friction between the rope and our hands. It was so hard to hold the rope and pull!IMG_2886 IMG_2888 IMG_2889 IMG_2890 IMG_2892

Rolling Cans

As we explored force further the 3/4 students investigated the effect of different size forces on tin cans. They gave their cans little pushes and BIG pushes to find out what would happen. They then used the vehicle of a storyboard to show their findings. At the end of the lesson we could claim that a little push (a smaller force) resulted in a shorter distance. A bigger push ( a large force) resulted in a longer distance.IMG_2856

The Year 3/4 students are a creative bunch! They thought of so many ways to move a marble as we began our new science unit on forces. We finished off the lesson drawing an annotated diagram to show our thinking about forces involved in games.

Comments Off on Dairy packages

Dairy packages

Well we finally reached the stage of creating our dairy packages. We had completed the background research and it was time to draw our designs, create the prototype, build the final package and then TEST IT!!

We decided that yoghurt was easier to design for, as trying to seal all the edges for milk was really hard! However we all learnt so much about materials and packages through this unit and were very proud of our final packages.

The year 3/4 classes have a challenge. To create a package to transport a dairy product to the Home Eco room. The product has to be stored for at least 24 hours and then the package easily opened to use the dairy product. Before they can begin the design the students are exploring all different things about package construction and the materials that make up packages. They have decided their packages might need to be made from waterproof materials that also have some strength.

Finishing Bats

Well the 3/4 classes have finished their unit on Living Together that ended with a focus on bats. They became science researchers, collecting information on the different microbats that live in our area and finally created models of their bats. The local Landcare group ran a ‘Batty night’ and the students work went on display. We are now bat experts and ready to look after the microbats in our environment.

Going Batty

The Year 3/4s are becoming experts about bats. They are doing scientific drawings, researching diet and habitat and role played using echolocation to find food.
