Team 4 - Science Exploration Day! Dry Ice
Today, we had a day where we busted myths! We had a lot of fun experimenting to learn about the scientific method and changes between solids, liquids, and gases.
In these first 3 photos, we showed a build up of gas as the dry ice went through sublimation by created a detergent bubble over the bucket.
DRY ICE AND WARM WATER
Here, we added dry ice to water to show the release of a gas during sublimation.
BLOWING UP A BALLOON
In these photos, we compared a balloon which had been blown up by using our breath (left), and a balloon which had been blown up by the gas created using dry ice (right). The balloon on the right was much heavier so it hit the ground first when dropped. You can also see that the balloon on the left is see-through where as the one on the right is not.
EXPLORING THE RESULT OF DRY ICE, WARM WATER, AND DETERGENT
Today we were doing rotations we had 3 rotation this is the last rotation I came too. In this rotation we were using dried ice and applying it to warm water.
We completed a 3-way rotation. In these photos, we are exploring sublimation (changing from a solid to a gas). We used dry ice to show this change in state through a number of experiments.
SAFETY
Did you know that dry ice is a solid and has a temperature of -78.5 degrees celsius? That is 78.5 degrees colder than frozen water (ice)!
It is so cold that whoever handles the dry ice has to wear gloves to protect their hands from the cold!

| We then explored the result of mixing detergent, warm water and dry ice. It created a foam made up of lots of bubbles which turned into a gas when popped! STUDENT LEARNING We finished by creating a blog post showing our learning. Check out Ayla's learning here! |

Ch...Ch...Ch...Ch...Changes!
Ch...Ch...Ch...Ch...Changes!
This term we are looking at science - the material world. So that means we are going to be Myth Busters and perform a lot of science experiments focussing on the changing states or matter, especially looking at solids, liquids and gases. It's going to be very exciting!
Check out our teacher's term introduction movie:

The Earth's Core
This term we have been learning all about volcanoes. So we also got to learn all about the earth's core and tectonic plates. But we didn't just do this in a boring way... Next time you have a watermelon see if you can identify and remember the parts and names of the core of the earth.

Rocket Day
We were very lucky to have Rocket Aerospace Education come spend the day with us and teach us how to build rockets. Here are some highlights of our exciting day.
