Milk Art

Today we had very small class due to district athletics. We also had some visitors from Room 10. We had a whole lot of fun by creating art in milk! We used blue top milk, food colouring, and a little bit of dishwashing liquid. The dishwashing liquid causes the bonds in the fat of the milk to break and move around. By adding food colouring, we can see this movement! Have a look at some of the creations in the photos below.

Term 3 Rocket Launch

Here is the video of the rocket launches we did as a class. Not all of them were captured and many have had to be shortened for time. It was a great way to end the term and our learning about rockets!

Planets in Room 4

In Term 3 we made planets for a newly discovered galaxy (Locus IV). Here are some pictures of the process we went through to create them.

Our Favourite Hubble Pictures

Yesterday in Science we started learning about Rockets and Space. We had a look at different rockets that have been used for different purposes. We also discussed the distances between objects in space. Did you know that if the Earth was 10cm in diameter, the moon would sit 3 metres away from it! It certainly doesn't look like it is too far away at night!

Below is our slide show of our favourite pictures from the hubble telescope. There are some truly amazing things in the universe!

Tumblewings!

On Monday in Room 4 we made tumblewings out of phone book paper. They are pretty easy to make but are tricky to fly! We have started practicing with them and hope to have a few people demonstrate how they work on Friday at Assembly.

Here is a link to the template if you would like to make it at home:

Here is a video of Room 4 learning to fly tumblewings in the rec centre:

Science Learning in Week 3!

On Wednesday we explored how moving air is different to still air. We found that moving air has less pressure than still air and that this pressure difference cause the still air to push in on the moving air. This creates interesting phenomena like: not being able to blow a ping pong ball out of a funnel, keeping a ping pong ball floating in a stream of air from a hairdryer (even when tilted sideways), and causing a ping pong ball to jump from one cup to another. We learned that this is Bernoulli's Principle (albeit a very simple explanation of it!). Check out our photos below of what we got up to and the video of our attempts at the challenge!

Lava Cups

Last week in Science Room 4 made lava cups with salt, oil, and water. We were learning how small observations can lead to understanding why or how something is happening. Have a look at our pictures to see what we were up to!

Ice Block Stick Chain Reaction

Today in science we had a quick look at energy and how it can be stored up. We then tried building chain reactions using ice block sticks. The tension of the wood causes energy to be built up and when it is released........have a look below and see what happens.

Slow motion of the energy being released!

Screaming Balloons

Today Room 4 had a go at creating screaming balloons. Along the way we learnt a bit about motion and sound. Check out the pictures of us in action.
