Today in science we are making wind racers for the next four periods. So I will be updating this blog as we go through this.
Method:To make adjustments to the cart so it can blow further when we use the wind or the leaf blower, for this to work we need to make a big one and make sure the wind blows it perfectly.
Design: We are going to make a wide triangular sail for our wind racer, We will use newspaper to make a triangular sail, we will also use sticks, strings/rubber bands for support.
Equipment:
- New paper
- Sticks
- Tape
- Hot glue
- Pieces of wood
- Pole
- Rubber bands or strings
Today in science i started making our sail. Stitched it with string and and now it starting to come together. I've also set up my stand for where the sail is gong to stay. I will be reinforcing it with sticks and cardboard next time i do this.
last week on Friday we had a test race to see what we could improve on our wind racers. That was really good for us and gave us some things to work on our wind racers.
