Dyson challenge cards

We had fun with some science activities last week and were joined by some friends. I used the Dyson challenge cards, which were free from the learning section of the Dyson website, and we explored expanding gases and viscosity. These were very effective and simple demonstrations and I love the concise explanations on the cards of the science behind it.

The children all loved the gloop, which melted into a liquid when left alone, turned to a solid when moulded and went very hard when poked with a sudden impact.

We also watched a YouTube video about armoured jackets made using a similar material which the children loved.
