    School Science Club Ideas

    Modified: Aug 26, 2022 · Published: Jan 16, 2020 by Emma Vanstone · This post may contain affiliate links · Leave a Comment

    Lots of people have been asking me for school science club ideas recently, so I’ve put together a collection of science experiments and activities that I think would work really well for Primary/Elementary school age children at a science club!

    Scribble Bots/Art Bots

    First up are our easy Scribble Bots. These are very simple to make using inexpensive and reusable materials. Children can try changing the size of the container, location of pens and alignment of the moving arm to see how the drawing pattern changes.

    Scribble Bot Challenges

    Build a robot that can draw an almost perfect circle.

    Create a robot that can draw a dotted line.

    Construct a robot with 8 pens.

    Try using a small cleaning brush instead of a pringles can.

    Earthquake Experiments

    Build towers and test how stable they are with different edible foundations. I’ve also got instructions for how to make a simple seismometer.

    If you don’t want to use food, playdough and clay foundations work as well!

    Two foil trays one filled with jelly/jello and one flapjack. The flapjack tray has a tower made from toothpicks and gummy sweets in the flapjack base. For an earthquake science experiment .

    Earthquake Challenges

    Investigate to find out how to make the tallest stable tower. One idea is to use stabilising toothpicks to form triangles.

    Experiment to find the most stable edible foundation.

    Craft Stick Chain Reaction

    Craft stick chain reactions are great fun and easy to set up once you get the hang of them. It’s definitely worth persevering with for the final spectacular result.

    Chain Reaction Challenges

    Have a mini competition to find out who can build the longest chain reaction.

    Experiment with longer sticks to find out if the reaction jumps higher.

    Design and build a different kind of chain reaction, this is sometimes called a Rube Goldberg Machine. Rube Goldberg machine’s are fantastic for a science club as children can work in teams to set up unique chain reactions!

    Make a Superhero Float

    Give children a selection of buoyant and non buoyant materials and ask them to find a way to make a small action figure float.

    Superhero Challenges

    Investigate to fine the smallest amount of material that can be used to make a figure float.

    Try to get an action figure to float by another method. Adding salt to water to increase the density is one idea. Or make a boat for the figure to lie in.

    Blow up a balloon with Alka seltzer.

    Try blowing up a balloon with Alka Seltzer, an effervescent vitamin tablet or popping candy. If you have the outdoor space this works really well followed by a film canister rocket. The fact that the children have seen just how much gas is released by an effervescent tablet makes it easier to understand why the pressure builds up so fast inside the film canister.

    Extra Challenges

    Experiment to find out how to speed up the blowing up a balloon reaction. Increasing the temperature of the water or adding more of the effervescent tablets are one way to do this.

    Draw a picture on a balloon so it expands as the balloon grows.

    Paper Spinners

    These are a super easy, low cost activity using just paper and paper clips. Paper spinners can be used for lots of different investigations, children can try dropping them from different heights, making different sized spinners and observing how they fall differently or adding more or less weight to the bottom end.

    Paper Spinner Challenges

    Have a competition to see who can make the biggest paper spinner that spins at least once on its descent?

    Find out the size of the smallest spinner that still spins.

    Race to see who can make the slowest falling spinner.

    Catapults

    Try catapulting different size and weight balls to see which go the furthest, or release from different angles. Children could also design a target and find a way for the ball to make a mark when it hits.

    Follow my easy catapult instructions to get started.

    Catapult Challenges for Science Club

    Who can make their ping pong ball go the furthest?

    Who can build the biggest catapult?

    Make ice cream with ice and salt

    This is another easy activity and a great demonstration of how salt lowers the freezing point of ice.

    To make ice cream with ice and salt, simply place sugar, cream and flavouring into one sealed bag, then place that big inside a bigger bag container ice and salt, roll and twist the bags together until your cream turns into lovely squishy ice cream! Experiment using milk, cream, flavoured milk and syrups to see which give the best flavour.

    Remember this can get very cold for little hands so gloves or a tea towel might be a good idea.

    Density Jar

    Make a density jar and ask the children to find objects to float on each layer. Give the jar a good shake and watch how the layers separate and use a pipette to drop water into oil observing how it makes spherical shapes.

    Once you’re finished with the density jar you can add a bit of food colouring to the water and turn it into a lava lamp by adding an alka seltzer.

    Density Challenges

    Who can make a density jar with the most layers? Try treacle, golden syrup, ice cream syrup, milk, water, honey, washing up liquid.

    Viscosity Races

    Viscosity Races are brilliant fun and a great way to learn how the thickness of  liquid changes how it flows.

    Simply mark two points on a large piece of paper and time how long each liquid takes to run between the two lines.

    Viscosity Challenges

    Experiment to find the fastest and slowest moving liquids you can.

    Find out what happens to the speed of the liquids if you change the gradient of the ramp.

    Skittle Magic

    Place skittles in water and watch as the colour dissolves from the sweets. You could try using warm, hot and cold water to investigate if changing the temperature of the water speeds up the reaction.

    Egg Drop Experiment

    How about this nice twist on the traditional egg drop experiment? Ask children to place different materials into sealable plastic bags, place an egg inside and then drop from high up to see which protects the egg the best.

    Try changing the material inside the bag, the surface the egg drops onto or size of the bag to extend the task.

    Egg Drop Challenges

    Who can build the most effective landing pad for an egg to drop on without breaking?

    Eggs with faces drawn on them next to three plastic transparent bags. One is filled with cotton balls, one bubble wrap and one cous cous

    School Science Club STEM Challenges

    Find out who can build the tallest spaghetti and marshmallow tower. Straws and plasticine also work well for this.

    Construct a tower with sugar cubes.

    Create a working water slide or marble run using cardboard tubes and foil.

    I’ve also got 40 fun science challenges with FREE printable instructions available to download.
