Chapter 13 - Expariment

Experiment With Sally

As I entered the classroom I noticed on the whiteboard in bright, green, bold writing the magnificent SALLY WAS COMING!,  I jumped with joy and excitement. Sally came into our extraordinary class to do a experiment with us. She told us to get into a group of four so me Victoria, Sophia and Daniel became a group. Each of us had  a number, I was lucky number two.

I had to bring the cup with the water and yellow food colouring to mix it. It had no salt in it and it was as yellow as an egg yolk. Next Ashley got the one with red food coloring in. It was as red as blood. It had one teaspoon of salt in it. The red food colouring did not mix as fast as the yellow food coloring. It’s because the water was more denser with the salt. Next Daniel brought the one with blue food colouring. It was as blue as the ocean. It had two teaspoons of salt, that meant that the water was really dense and the blue would not mix.

Next we got some tubes. Sophia was first at using them. She took one and put it into the yellow one and then covered the other end with her thumb. She did the same with all colours. The colours did not mix with each other when she held it straight, but when she put it sideways it turned into a yucky brown. We all had turns mixing colours together. I mixed blue and red to make a fantastic purple. Then I mixed blue and yellow to make a wonderful green. Then I mixed red and yellow to make incredible orange. My tube turned into a magical rainbow. I thought that the experiment that we did  was great.
