Mister and Master Wobbleheads
You kids are creative. Thanks to Mrs Newson, a wonderful selection of characters were created. Well done to those of you who were patient and succeeded in getting the centre of mass in the middle. Have others managed it at home?
Making an Electromagnet
Take some thin copper wire, a high carbon steel or iron nail and a 4.5 volt battery. The winning team, with patience, picked up nineteen paperclips with their electromagnet. How could you make the magnet stronger still?
Fantastic Flingers
These catapults are similar to the trebuchet. Well done to all the teams for getting theirs working. An impressive distance of nine metres was measured for one projection.
Bath Bombs
Have you tried yours out in a sink at home? Could you smell the oil?
Alien Blood
This smelly organic chemical dissolved the polystyrene!
Handwarmers
An example of an exothermic reaction. Do you remember the name of the chemical which was added to water? How about sketching a diagram showing what happens to the molecules on dissolving?
Iron Out Your Cereal
We found that Kelloggs do add fine iron granules to their Rice Crispies. It means that your haemoglobin can carry more oxygen to all the cells in your body. Do you remember the shape of a red blood cell?
Children brought in an experiment prepared at home, which included chromatography, an exploding volcano, optical illusions, a Cartesian diver, an oven clock and making a floating compass.
Racing lego vehicles
Can you draw a forces diagram, showing friction, weight and air resistance?
Custard Behaving Strangely
A swimming pool filled with custard? Yes, it's true. Take a look at this four minute video clip:

Did you know that paint, cheese and milk are also colloids?
Preparing DNA from kiwi fruit
Using detergent, ethanol, salt and patience.
Racing hovercrafts
Why can these vehicles move more quickly than boats?
