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…
This viscosity experiment is a fun way to discover how different liquids flow. Or just to have a race with ketchup and other kitchen ingredients! The rate at which different fluids flow can vary considerably, this is called resistance to flowing viscosity. We did this on a big board in the garden, but it works…
Hawaii is the 50th state of the United States, nicknamed The Aloha State (Aloha is the Hawaiian way to say hello and goodbye ). Hawaii is more than 2000 miles west of California and is made up of 132 islands, although only 7 are inhabited. Hawaii’s first known inhabitants arrived in canoes from the Marquesas…
Have you ever wondered what shape a raindrop is or why a drop of water forms a sphere? Water droplets are spheres because surface tension pulls the molecules into the smallest possible area to give the lowest ratio of surface area to volume. This shape is a sphere. What shape is a raindrop? A falling…
Today, we’re learning about friction with some fun friction experiments! First up is a super simple DIY friction ramp. This is a great way to demonstrate how some surfaces have more friction between themselves and another object than others. What is Friction? Have you ever tried sliding on a wooden floor or an icy surface?…
Isaac Newton’s laws of motion explain the relationship between an object and the forces acting on it. The laws might seem very obvious today, but when Isaac Newton was alive, they were revolutionary and formed the basis of modern physics. Isaac Newton built on ideas from Galileo Galilei, Jean Richer and Rene Descartes. It is…
Our easy rock investigation making edible rocks is a great introduction to different types of rocks and the rock cycle. Chocolate is perfect for learning about the rock cycle as it can be heated, cooled and compressed just like real rocks. This activity uses chocolate to demonstrate how three different types of rocks form. Edible…
Here at Science Sparks we love hands-on science experiments and if you can eat them afterwards so there’s no wastage then even better! I’ve pulled together my top 10 awesome edible experiments for you to try below. I would love to see your creations and ideas too! Awesome Edible Experiments Build and test a candy…
