Week 1: Starting to think about science: Gathering and Interpreting Data.

After today's experiment I placed myself on relational because I was getting involved in the experiment. The slime was chunky because of the starch and cornflour and water  mixing together. For my inferences I put myself at multistructural because some of the questions I was asking I got wrong.

Week 2: Balloon Rocket experiment
My observation skills were relational because after the balloon finished I write down what it did and I did all of the trials but not the paper on the balloon. What I noticed was that when I put a lot of air in the balloon, it just let the air out and when there was a little air left it went forward. So I wonder why it did that.

Week 3: Balloon Rocket experiment
When we put paper on the front of the balloon it didn't go anywhere but when we put it on an angle, it went further and spun a bit. Perhaps there was more weight on the balloon.

Week 4: Trebuchet experiment
I noticed that the projectile in the sling lets go at a certain angle, then the projectile fires out with the force pushing it through the air. I wonder what would happen if it let go at a different angle would it smack the ground or go zooming through the air and crashing in the bin.
When we put all of the weights in with the tennis ball it went further than the heavier ball. Also it had a big difference I think it is the weight in the ball. Also I saw the arm was pushing through gravity for the the projectile to launch.
My data gathering is multistructural because I am confident with my observations and I take photos to see what happens with Trebuchet. My inferences are multistructural because I can only make many inferences but they can sometimes be wrong and sometimes it can correct.
