Science Journal

Week 1 2017: Slime
This week we were experimenting with slime. I saw that the slime was very sticky and thick, I think this is because they used cornflour, water and food colouring to make the slime. Later that morning we used our slime to tip on Mr Anderson’s head. I was wondering whether or not Mr Anderson would slip over the slippery slime. I think I am multi structural because I have lots of ideas.

Week 2: Balloon Rocket
In week 2 we explored forces with balloon rockets. To create this we used string, balloons and straws. We were experimenting how far the balloons would go on the string. While we were doing this activity we were observing the forces and variables of air pressure, different gradients, and drag. I wonder why sometimes the balloon would slide straight and sometimes it would just spin around? I think I am multistructural because I can share my ideas with others. 

Week 3
In week 3 we did the same thing but used straws for our balloon experience. The straws were used for the balloon to drag smoothly on the string causing less friction. I filled my balloon rocket with water but when I attached it to the straw it just broke the string and did not slide. I think this happened because the water was too heavy for the string. My goal was to stay on task.

Week 4: Trebuchet 
We used the trebuchet to experiment how far the ball would fly in the air. I now know from what I recorded
