Hero Engine part 2
This is my Hero engine part 2. I used my grandfathers drill to make the holes, I chose the size of the holes that I wanted to use. This tin can, only spun 5 times around. My best can spun 18 times around. The difference I think, was that I put too many holes in the can I used for my part 2 video. Part three is coming to tomorrow.

Hi again Anna! I see Hero part 2 results were a lot less than your first lot! Fascinating!! Why do you think more holes meant less turns? Do you think it is helpful when you get quite different results in experiments? Awesome work on this! Keep focussing on what you observe! Ka pai tou mahi!
ReplyDeleteHi Anna,
ReplyDeleteVery impressive technology, I loved watching as you imported the photo and videos and put them into your Inquiry folder, then onto your slide. You are learning so much.
You have also learnt a lot about making water - propelled engines from soft drink cans, great
observations.
Xxx
Yes the pressure of the water and gravity forces the water out! Great thinking Anna!
