Science Experiment

Method:

1. Place the six test tubes in a test tube rack label them one to six.

2. Using the measuring cylinder fill the test tubes with 10 ml (all of them) Using the remaining water fill them all with 5 ml

3. Using your tweezers add a single crystal (The smallest one possible) Into the first liquid

4. Gently sake the test tube until the crystal has dissolved.

5. Using the transfer pipette, carefully remove exactly 5 ml from test tube 1 and pour it into test tube 2

6. Rinse the transfer pipette thoroughly to ensure that no purple solution remains.

7. Gently shake the test tube 2 and repeat the transfer process, transferring 5 ml of solution from test tube 2 to test tube 3.

8. Rinse the pipette again and repeat the transfer process for test tubes 4,5 and 6.

In science, we've been learning about mixtures. So yesterday we put Some purple crystals and then they dissolved into the water and the water became purple. Then got a squeezy thing that sucked up the purple water and then put it into the other test tube with more water in it and so on six times. The purple water got lighter and lighter every time we did it. But ours was different because the second test tube had a chemical in it that made our second one yellow instead of purple but we kept going.

We also learnt what dilution and solution means let me tell you

1. the action of making something weaker

2. the action of making something more concentrated
