We’ve made lolly stick chain reactions, Easter egg chain reactions and now we have a GIANT chain reaction. We actually made this a few years ago, but when I looked for the post today I couldn’t find it, so there’s no photos just this video. Simply grab a ball ( any size ) and some…
Homemade Water Walls are a great summer activity. We usually make one at the start of summer and leave it in place for as long as it survives. You can be creative and use a trellis, a fence, or anything else you can wrap tubing around. Add buckets and funnels for a summer of watery…
If you asked my son what his favourite all time science experiments are, he’d probably say the bottle rocket, followed by his candy house, so today, we’ve got some great candy experiments and activities for you to try at home. These easy science experiments with sweets are great for using leftover sweets after Halloween or…
Next in my Around the World in 50 Experiments series is Germany. Germany has the second biggest population in Europe but much of the land is still covered in forest. Germany is the birthplace of the Grimm Brothers and home to many much loved Fairy Tale characters including Rapunzel, Little Red Riding Hood, Rumpelstiltskin, Snow…
Electricity and circuits are great fun for children ( and teachers and parents ) to learn about. This collection of electricity science projects and experiments are all easy to try and very satisfying. Watching a bulb or an LED light up because a circuit works always seems very rewarding, and the bonus is you can…
This simple science activity shows children how to draw a circuit! It’s great for learning about electricity and a fun introduction to circuits. Graphite is made up of carbon atoms with delocalised electrons which are able to move through the graphite. The electrons allow graphite to conduct electricity. You can demonstrate this by creating a…
The answer is more than I had! We managed to light an LED with two lemons and could see between 2 and 3 volts from the lemon batteries on a voltmeter, but the current passing through was very small. Even with 6 lemons we couldn’t light a small screw lightbulb. Turn a lemon into a…
Art Bots or Scribble Bots are great fun and provide many investigative opportunities. This simple version uses a small motor and pens fixed around a pot. The motor makes the arm ( glue stick or cork ) spin, which in turn makes the Scribble Bot move. Pupils can be given challenges, such as finding a way for…
Making circuits is great fun for kids of all ages. If you have little ones play dough circuits are a great kid-friendly activity for learning about electricity. I’ve used these with children as young as 4 ( supervised, of course ) who have loved the creativity of the whole experience. For older children, cardboard circuits,…
How much does the Earth weigh? We obviously can’t put the Earth on a gigantic scale so it needs a tricky calculation to work it out. Scientists calculate how strong the gravitational pull on other planets is to calculate weight. Heavier planets have a stronger gravitational pull. We talk about a planets mass rather than…
