Jumping Frogs

A fun way to demonstrate static electricity is by making jumping frogs. Equipment Balloon Paper, cut into shapes. We used sugar paper, but tissue paper would also work brilliantly. Woolly jumper or hair Method Cut up your different types of paper into frog shapes...

Viscosity and Jelly

We recently tried exploring viscosity of fluids using water, oil, golden syrup and honey. The main problem we had was that for some of the liquids the marble dropped too fast for us to time. With this in mind we decided to try the same experiment with different strength jellies. I made three different jelly mixtures in test tubes. Solution A – Normal Jelly Solution B – Normal Jelly diluted with half water Solution C-...

Exploring Viscosity

What do you put on your porridge? We noticed that sometimes our honey and golden syrup take a long time to pour, whereas water and milk pour almost too fast. We’ve done viscosity experiments before by letting the liquids flow down an inclined board. In this viscosity experiment we attempt to refine the procedure by comparing fluids by dropping a marble through them. This is also a great opportunity to practice drawing and using...

Candy sorting

In the UK we have some chocolate covered sweets called Revels. Inside each bag are different flavoured chocolates, maltesers, plain chocolate, coffee flavour, orange flavour, toffee and chocolate covered raisins. They seemed like the perfect thing to use for a sorting activity. I set the children the task of sorting them into the different flavours without eating them. We talked about the different ways we could tell the difference...

Acid or alkali? Making a red cabbage indicator.

Acids and alkalis are substances that can be found in the science laboratory and at home all around us. Acids can be found in the food we eat, in our body and some acids can be very harmful. Alkali’s are another group of chemicals that react with acids. Substances such as soap are alkalis and bicarbonate of soda which we use in baking but also harmful things like bleach. So how do we know when a substance is an acid or an...

Filtering Experiment – can you do better?

We’ve tried a filtering experiment using dirty water before, using kitchen roll as the filter. Today we tried something a little different. We looked in the garden for three things that might make good filters, and chose large stones, small stones and sand. We talked about which we though would be the best filter, and decided the sand would probably work best as it was the smallest. What you need Large stones Small Stones Sand...

What makes Popping Candy pop?

As part of our MAD Blog award from Seagate we received an amazing box of retro sweets, including this Fizz Wizz popping candy which we couldn’t resist using for an experiment and to find out what makes popping candy pop.     We all tried the popping candy first and giggled as it burst tickling our tongues. We decided to see what else would make the candy burst, so placed some in oil, water and vinegar. What you need:...

I used a heart cookie cutter to get the shape. What you need: Water Bicarbonate of soda/baking soda Vinegar Food colouring Instructions Mix some water with the bicarbonate of soda, I used a whole packet of bicarbonate of soda and...
