Imploding Cans
Aim – To implode a can
Equipment – Bunsen burner, Can, cold water, tongs, fire
Method – Putting a can into a container full of water.
Results – The can shrank into cold water while it was boiling with hot water inside of it.
Conclusion – What Happened? The can was half full of boiling water and we to the Bunsen Burner had to use tongs to put it into a container and once we put it into the water, It shrank.
As you see it shrinks once it touches the water with ice in it.
Tea Bag Rocket Experiment
Aim: Making it fly
Equipment: Heat proof, Tea bag, Fire,
Method: I watched it fly
Results: It was being lit up by fire which made it fly
Conclusion: What Happened? The heat from the fire causes the air molecules inside the tea bag to become energised and move around quickly. And that’s why it flew up.
As you can see in this image, this is what happens when you fire the tea bag and it reaches the bottom of the tea bag.
Solutions and Solubility
Filtration Experiment What is Filtration?, Separating Different sized particles out of mixture.
Solid A solid could range from anything but for this example its Soil & Dirt. Filter A filter is made from Paper/cloths and other things the Filter catches the solid as the Liquid drips through into the.
Funnel The Funnel is something to hold the filter and a pipe for the water to drip through it. Beaker The beaker is the bottle for the water/ Liquid to go into.
Filtration Experiment. What is Filtration? Separating Different sized particles out of mixture
Solid the solid could Range from anything but this example is Soil/dirt. Filter Paper filter has tiny holes for the water and the paper holds the Solid up. The Funnel is to hold the paper filter and a tube for the liquid to drip though. Beaker

Chromatography
It’s a scientific technique used to separate a mixture of two or more coloured pigments, such as inks
and dyes. The pigments separate because they have different solubilities in a solvent. This means
that the more soluble pigments are carried faster, and therefore further, by the rising solvent.
Aim: To separate difference pigments in links or dyes using paper chromatography.
Equipment: Pencil with ink, 2 beaker big one small one. Filter paper and tape, water to pour into the beaker.
Method: To see what colour comes from the pencil.
Results: red yellow and green came out.
- Name the pens that contain one pigment? Yellow, Purple, Dark Blue, Light Blue,
- How many different red pigments were used in the 8 marker pens? Justify your answer. One,
- Which of the pigments used in making of the pens is the least soluble in water? Dark Blue,
- Did the manufacturer use the same yellow in the orange and green marker pens. Justify your answer. Yes,
Saturation Experiment
A solution will become saturated when no more solute will dissolve in the solvent. A solution that is saturated has a high concentration. If some of the solvent evaporates from a saturated solution, the solution becomes supersaturated and crystals of solute will start to form.
Aim: Our aim was to make some Krystals by using Magnesim salt with hot water.
Equipment: Beaker, Magnesim Salt, a tooth pick, Bunsen Burner, cotton, string rod,
Method: 1. Pour 150ml of hot water into a 250ml beaker, 2. Add a spoonful of copper sulfate powder and stir until it dissolves. 3. Repeat step 2 until no more copper sulfate will dissolve. 4. filter the solution into a clean 250ml beaker. 5. Pour a small amount of this solution into a watch glass. 6. Label your watch glass and beaker and place the watch glass on a window-sill overnight.
Results: We have not made Krystal’s yet at the moment.
