Fizz in the kitchen

Recently, I've used a different science activity book with the younger children: Fizz in the kitchen by Susan Martineau. 

These are a few of the activities we have done from the book.
First, we did the classical demonstration to show that air takes up volume. A cup with dry paper towel in it was inverted into a bowl of water.
We held the cup under water for the count of 10, took it out and checked to see whether the paper towel was wet or dry. This caused great excitement and much repetition to see whether the result was genuine.

Another classical experiment was covering coins in tomato ketchup. We modified this and also tried milk and vinegar. This gave the children the opportunity to predict what would happen.

Rather flawed with the milk running into the vinegar. Results about an hour later with the coins in the same positions. Interesting, the vinegar didn't work well-I suspect because the liquid ran off the coin.

Just one last picture the density demonstration putting marbles into different liquids and seeing which marble moved most quickly-we used oil, washing up liquid, water and golden syrup and then lined the jars up in order of density.

We've enjoyed this book although most of the activities are very classical and if you do much science with your children you may have already done some of them. However, the explanations are attractively presented, clear and there is useful application to real life. All of these activities are easy to do around the home so this would be a good starting book for science activities for younger children. It is always difficult to suggest ages but I would think ages 3-7 with parental supervision.

I brought this book for our own use-the opinions are my own.
