There once was a Galaxy
His name was Star
He was a weird star
tera tetahi ikarangi
ko Puanga tona ingoa
He ikarangi harakiri

Concentration - Making a dilution series
Aim - Our aim was to a dilution series to investigate concentration
Method - 1. Place the 6 test tubes in the tube racks and label them from 1 to 6
2. using the measuring cylinder fill test tube 1 with 10 mL of water , fill the remaining test tubes with 5 mLs of water 3. using your tweezers add a single crystal of potassium permanganate to test tube one 4. gently shake the test tube till the crystal dissolves 5. using the transfer pipette carefully remove exactly 5 mLs from test tube 1 and pour it into test tube two 6. rinse the transfer pipette thoroughly to ensure that process transferring exactly 5 mls 7.gently shake test tube 2 and repeat the transfer process transferring exactly 5 mls of solution from test tube 2 to test tube three 8.rinse the pipette again and repeat the transfer process for test tube 4,5, and 6
Equipment - A potassium permanganate crystal , six large test tubes , tweezers , a plastic transfer pipette , a test tube rack , 10 mL measuring cylinder
