Hello everyone! (: We had another experiment know as the Energy Tower Experiment, so I'll be writing about it here.
In this experiment, we were supposed to lift the "Treasure" up to a height of 15cm. The "Treasure"- a 5 gram weight-is to be lifted using reusable energy power, in which case, only water power is available.
Challenges were faced, surprises were given. We took 1h to create our first experiment, which failed. Then, we spent 5-10 minutes on another experiment then we succeeded.
Our first experiment involved using corrugated board to make the wheel, but it did not work very well due to water causing the clay to have the inability to stick, and friction about certain parts. The made water wheel was also very unstable. As for the second experiment, we wrote down the procedure detailedly since it was successful, so here it is!
We started off with 6 spokes, but after observation, we realised it was not able to fully lift the load, thus adding another 2 spokes, making it a total of 8. From this, we can see that with more spoons used, the faster the wheel will spin and the load get lifted.
Here are some photos and a video!
At the end of the experiment, my group did a self-reflection, and we realised that to succeed in an experiment, we must not think to complicated and too straight (making a water wheel). Just think of how some things can be used as replacements for others and it still can be successful.

1. Place two bottles in the sink as stands.
2. Fill them with water to ensure that it does not topple.
3. Shape a block of plasticine to a circular disk
4. Cut off half of the spoon handle and pierce the rest of it into the plasticine at an interval of around 3 cm
5. Insert a wooden skewer through the middle of plasticine disk.
6. Secure the tips of the wooden skewer onto the bottle caps.
7. Tie the string to the weight, then tie the other end onto the wooden skewer.
8. Pour water onto the spokes of the waterwheel.
9. Repeat with the interval between the spokes as 2 cm.We started off with 6 spokes, but after observation, we realised it was not able to fully lift the load, thus adding another 2 spokes, making it a total of 8.
