Inquiry | Experiments

This week, our session was about applying experiments to get a quality result.

First, we looked at the procedure and saw that the procedure was not specific enough, because of this, we needed to add more detail. We added more detail by specifying how much water we use and how much material we needed.

Next, we chose the materials that we wanted to experiment on. The materials that we could chose were: nappies, cotton, rocks, sand and paper towels. My group chose the cotton material. The experiment was about what material can absorb the most water. 

We then prepared our experiment. We measured 100ml of water inside a beaker, got a tote tray to prevent spillage, and weighed our material to get 50g worth of cotton.

After getting the experiment ready, we started. We poured the water on the cotton and once all of the water was poured, we let the cotton absorb. Then, we took out the cotton and put the excess water in a beaker. We measured the excess water. Our experiment had the results of: 64ml was aborbed and 36ml was not absorbed. 

I enjoyed this experiment and learnt how to conduct an experiment. I also learnt that cotton is an absorbent material.
