Last week we had Ms Davis and Ms Dudding show us an experiment called " Elephant Toothpaste ". They told us about a physical reaction and a chemical reaction. Physical reaction means the experiment is reversible, so it can change back, for example water can freeze and melt back to water. Then a chemical reaction is when it is changed, it is irreversible. Like a cake, by the time you have mixed and baked the cake, it won't change back into the way it was. As we watched the elephant toothpaste, we found out it didn't reverse back, this experiment was a chemical reaction.
This blog is a record of my learning from Panmure Bridge Primary School through to Tamaki College.

Our science slide
This is my groups slide about how to be a scientist. I am in group 3. We have been learning about what scientist need to do and ask. So if we get stuck, we can look at this.

Science - Oobleck #2
This was our second science project. Above as you can see we have made a substance that is solid when you touch, but liquid when picked up. The teacher asked if it was a liquid, solid, or gas, and guess what...... none. It is actually called a compound.That is when 2 or more things combine. Have a look.
Science #1
This is another google drawing about my baking soda and vinegar. This ones just like the other one I did last time, but this one has the equipment you need to use, and you've got the steps to follow.

VINEGAR AND BAKING SODA
On Wednesday 2nd march 2016 we did a science experiment. We put a small cup in the bowl and filled it with a tablespoon of baking soda. Next we poured some malt vinegar in the cup, inside the bowl, and it bubbled and overflowed. But my hypothesis ( that means prediction ) was that it would explode and spill all over everybody, but I was wrong. We also did one with white vinegar, and that was WAY more fizzier and more bubbles. It even looked like sprite.
