Experiment Day 2

Task Description: Today for our first science project, we had to do a base vs acid. We saw in two different cups what baking soda would look like in water, and what baking powder would look like in another cup, Mrs Stone then added the base together with the acid and the baking powder didn’t go down and didn’t look the same as the other cup. I found this science project very fun to do with my team! I hope to do more like this in the future!

Experiment Day 1

Task Description: For this mornings task, our science session, we had done some experiments and  we had to answer the following questions about both physical and chemical changes. I found this quite exciting to do though it did need a lot of responsibility, we did the first science lesson which was based on cornstarch and a 1/2 cup of water, we didn’t know what was happening but as we did the procedure, we started finding both of these things hard to stir. We had to put a hand/finger into the bowl including both the water and cornstarch. It was both liquid and solid together, I found this very gross to touch at first and then I got very playful with it. When I pulled my fingers out of the bowl, I could see the cornstarch starting to dry up on my finger, I found it so weird and sticky. After we played with the cornstarch we had to wash our hands outside, I thought we had to really wash our hands thoroughly but then the cornstarch just slowly disappeared unless that was just my hands. In the end we managed to complete one of the two science projects. I hope you enjoy!

Matter 3

LI 3: We are learning to explain what happens to materials when they are heated and cooled. 


When particles are heated they: have more space between them and move more quickly.


When particles are cooled they: Decrease in space and move a lot slower then in heated water. 


What does this have to do with building houses?


When the particles have more energy they take up more space. This is why things expand or get bigger when they are heated and contract or get smaller when they get cold. When building, architects need to think about how much the materials may expand in the heat of the summer and contract in the cold winter months. Metal railway tracks have small gaps so that when the sun heats them, the tracks expand into these gaps and don’t buckle.


Why are there bumps or small gaps in the harbour bridge?


The harbour bridge has small gaps so that when the sun heats them, the tracks expand into these gaps and don’t buckle.

Chemical Or Physical Change?

Task Description:

Today for the last session of the day, we had to do our last inquiry task before we start getting into physical hands on science experiments. We had to match the chemical and physical reactions to each other. I thought about each one when I was doing this. I think I got most of them right! I hope you enjoy looking through these (maybe last)inquiry slides.


Task description:For today’s maths we had to get into mixed groups, while we were in mixed groups we had to do a science experiment for sugar dissolving in water. We were and still are learning how to make accurate measurements using a variety of measuring equipment. We had also learnt some new vocabulary and these words were solute, meaning the substance (sugar) being dissolved in the water, the next word was solvent which meant dissolving (water) solvent was the water that dissolved the sugar. And the last one was the solution which meant a mixture of 2 or more substances. In the end we learnt and enjoyed the science experiment.
