Interesting, the experiment they send us at my daughter’s school. It is a simple experiment to do with our children and introduce them to the wonderful world of science, although with this we may be conditioning them.
If you want to spend a weekend teaching your child more about space, astronomy, science and aeronautics, I let you a collection of resources that ESA (European Space Agency) has hung for teachers and children.
You can take advantage of the fact that the subject is not very old to introduce to your child. That an object has been sent from the earth to a comet at 500 million km and that it travels at 60,000 km / h because it has to impress you. Well, this is what the Rosetta Mission has done with the Philae probe.
Some years ago, David, an elementary School teacher wrote me asking if I can help them designing a 2×2 Rubik’s cube for children.
They want a mathematical project for kids based on Rubik cube. Fastly I answered with some links to learn to build 2×2 and 3×3 Rubik’s cube with dices and magnets. The are really cool hacks. But David needs something easier and cheaper. They came with simple premises.
- Children of 10 years must be able to build it, so we forget about elaborate and dangerous tools and processes
- and it has to be cheap, very cheap
although everything must be said they just wanted a minimally manipulable cube.
This is an easy experiment, awesome for kids. Making it we will can explain our children what bioplastic are and introduce them into a chemistry world. Even in historical facts.
Galalith or Milkstone has an interesting history behind it. It was use to produce gemestone realistic imitations.
Other Galalith names: Milkstone, Erinoid (United Kingdom), aladdinite (USA), Casolith (Netherlands) and lactoloid (Japan).
