Definition of the scientific method

Hi Guys

Today we learned the scientific method for an experiment
Here are my findings:

Aim: What you are trying to find out/make happen.

Hypothesis: An educated guess.

Equipment: Material used for the experiment.

Steps: The order the experiment is carried out in.

Findings: What you found out happened in this experiment. sometimes you write them/Put them in a graph/Table/ect

Conclusion: Findings and research all summarised together.



____________________________Marshmallow catapult___________________________________

Energy Transformations: 

Marshmallow catapults

Hypothesis: That the catapult will work ok with some flaws and won't be 100 percent perfect.

Equipment:

1. 1 clean cup
2. 1 balloon
3. 1 pair of scissors
4. 1 marshmallow

Method:

1. Cut the bottom off the cup with the scissors.
2. Tie a knot at the neck of the balloon and snip off the tip.
3. Stretch the balloon over the top of the cup. You may find this a bit tricky to start with, but after making a few it becomes easy.
4. Pop your marshmallow into the cup.
5. Fire the missile by pulling the knotted neck of the balloon and letting go. You will be surprised at how far it can travel2
6. The open end will fold together when you stretch the balloon, but this will not stop the missile from firing.

Results (Describe what you saw, take a pic/video):
My catapult-launched approx 1 meter far from our firing point

Discussion (What were the energy changes happening, explain what you saw):
when we put it into it was potential elastic energy and kinetic.

Conclusion (Was your hypothesis correct, did the experiment work?):
My hypothesis was partly correct as it did work too well and has flaws.
It was a fun activity/experiment.

BYE!
