20 Autumn and Fall Science Experiments

Over the many years I’ve been writing Science Sparks, Autumn has always been my favourite season to design themed activities for. I love the colourful leaves, dark nights, cooler weather and of course the run up to Christmas is always exciting too! This collection of fall science experiments and activities makes me smile every time I read it and hopefully has something to excite kids ( and adults ) of all ages.

I also have a fun collection of fall STEM challenges you might like!

Fall Science Experiments for Kids

Create your own exploding seed device or spinning helicopter seeds to learn about seed dispersal. These are lovely hands on activities that would work well after going on a treasure hunt to search for different types of seeds.

This leaf chromatography experiment from Playdough to Plato is fascinating and very colourful.

Fall Kitchen Science Experiments

Learn about changes of state in the kitchen by making toffee apples and treacle toffee. Which is your favourite?

Make spiced apple cider and learn about filtering at the same time.

Try some apple bobbing. Do you know why apples float on water?

Fall Sensory Science Activities

Get creative indoors or out with some lovely autumn themed ice. You could try adding a little salt ( be careful as this makes the ice feel much colder ) to melt it faster or use a pipette to drop warm water over the surface.

Use leaves to make prints in play dough and learn to identify different types of leaves.

Get messy with some Autumn gloop. Can you scrunch the cornflour up into a ball? Do you know which properties of cornflour and water make it a Non-Newtonian fluid?

Have some sensory fun with blackberry playdough, from Rainy Day Mum.

We love this beautiful autumn sensory table from The Imagination Tree.
