Science

This week for science we did a experiment about dilution. Dilution is when a liquid has been made thinner by using water or a solvent. Here is how we did the experiment 

Equipment:
Potassium Permanganate crystal, Six large test tubes, tweezers, a plastic pipette, a test tube rack, 10mL measuring cylinder

Method:

1. Place six test tubes in the test tube rack. 

2. Using the measuring cylinder fill one test tube with 10mL of water, fill the rest up to 5mL of water. 

3.Using your tweezers put the single little piece of the crystal inside the 10mL test tube. 

4. Shake the test tube until the crystal dissolves and it is very concentrated. When something is very concentrated the mixture contains a lot of solute.

5. Using the pipette take out 5mL of water from test tube 1 and transfer it into the second one.

6. gently shake the second test tube and repeat the transfer process till all the test tubes are filled. 

I hope you try out this experiment because it is really cool, have you ever tried to do this experiment?
