Here at Science Sparks, we love experiments using eggs. Eggs are generally inexpensive and can usually be eaten before or after the activity, so there’s no waste. These are my five favourite Egg Experiments. Five Eggy Experiments Make an eggshell disappear Make an eggshell disappear! This is like magic! Watch the shell of an…
I wanted to get my children thinking about the process of investigation today, so we talked about how we could test whether some structures were stronger than others using DUPLO. They decided to build three different shaped towers and test them by rolling a ball at them. The first is a simple tower, the second…
When I brought out the spaghetti and marshmallows, I think my children thought we were having some kind of weird and wonderful dinner, not building structures. This is a great STEM activity for children of most ages, as you can tailor it to their understanding. I let my 2-year-old build whatever she wanted, and she…
Today we are looking at the difference between things being wet and dry. This investigation is so simple I did it with my 18 month old,  who loved dipping her fingers in the different pots and saying ‘wet’, so it is a great preschool science activity but can also be extended for older children. What you…
Why does food rot? Have you ever noticed that if you leave an apple (or any fruit ) for too long, it starts to rot or decay? This can lead to significant food waste, so it’s important to understand how to store food items to keep them as fresh as possible. Why does food rot?…

Making patterns is a fun activity that’s easily adaptable for kids of different ages. Our favourite way to make patterns is using DUPLO or LEGO bricks. What is a Pattern? A pattern in a sequence that repeats itself is a concept that is quite important for children to grasp. We started very simply with Duplo…
I am a huge fan of HABA toys, so I was very excited to receive this Terra Kids Windmill construction set from their Terra Kids range to review. Terra kids products are a great introduction to science and nature and include not only construction kits but also equipment such as telescopes and microscopes for exploring…
This is a brilliant investigation for finding out how waterproof different materials are. I printed a picture of a chicken and asked the children to colour it in, then gave them a selection of materials to protect the chicken from water. What you need Instructions Place the squares of material over the picture. Sprinkle water…
The transformation from Caterpillar to butterfly is one that hooks in children, however old they are. We are big fans of the Hungry Caterpillar by Eric Carle in this house, and it is a great way to introduce the lifecycle of a caterpillar. Firstly we read the story. Then we talked about a cocoon and…
