This science trick is so simple, but so much fun. It's also easy for students to replicate at home. Equipment: -Two empty 375ml cans -Approx 100ml of water Method: -Secretly pour about 100mls of water into one can. -Have a student try to balance the other empty can tilted on its bottom rim. It is impossible. -Then amaze them, by easily balancing your ‘magic’ can on its bottom rim (they don’t need to know it has water in it). Explanation: It works because the water adds weight to the bottom of the can, changing its centre of gravity and allowing it to balance in otherwise impossible ways.
Was the classroom teacher unexpectedly away & unable to leave set work? Can you see that science is one lesson that is usually scheduled for the day? This is an easy science experiment that I originally saw on the Steve Spangler website. It is suitable for all age levels - these photos were taken while I was doing this activity with my 2 year old! Head down to the cafeteria or canteen & see if you can buy some milk. You should also be able to find suitable containers, food dye & a little dish soap from the neighbouring classroom teachers. Colour Changing Milk Equipment: A shallow bowl, plastic plate or a tray (like a cookie baking tray) Food colouring (at least 3 different colours) Whole milk - low fat milk will not work for this experiment Liquid dish washing soap Method: -Carefully pour the milk into the tray so
