We love egg experiments here at Science Sparks. We’ve investigated air pressure using eggs, transformed egg whites, tested how strong an eggshell is, and even made eggs shrink. Today, however, we’re going to find out how to make an eggshell disappear. It sounds impossible, but it is actually very simple! How to dissolve an eggshell…
Todays preschool plant activity is very simple and is especially aimed at younger children. We wandered around the garden looking at all the plants and flowers discussing which were big and which were little and talking about the different colours. Then we talked about what the different parts of a plant are called. Once back…
Today the lovely Maggy is visiting from Red Ted Art with a great activity to introduce the idea of aerodynamics and trajectory to your children. How wonderful to be visiting from Red Ted Art today! It is no secret that I LOVE Science Sparks and all that these wonderful ladies have to offer us. I loved…
The Primary Science Magnet Set from Learning Resources is a great science kit for little people. The set contains 14 pieces and 10 easy-to-follow activities printed onto large cards. The pieces are chunky and easy for little hands to hold and fit together, and the activities are clearly and thoroughly explained. The set is aimed…
Lemons float on water, but do you know how to make a lemon sink? This fun science trick will baffle your friends and is a great way to learn about density! Photo taken from Snackable Science What you need to make a lemon sink Bowl Water Lemon or orange We tried pushing a lemon down…
This germination science investigation is very simple but fascinating. Did you know you can grow a bean in a jar with just a little water? Once the seed has germinated, you can place it in soil for the plant to finish growing. The jar allows children to see the seeds, roots and shoots easily. What…
It is so annoying when getting to the end of a ketchup bottle, and you have to keep banging to get that last bit out. Why is this? Because ketchup is thick and does not flow as easily as other fluids. We call this resistance to flowing viscosity. The rate at which different fluids flow…
This week we are investigating why balls bounce and how different balls bounce differently on different surfaces. Balls bouncing seems like a simple concept, but the science behind it is quite complicated, so please bear in mind that we have simplified it for our audience. I asked the children to choose three balls of different…
Growing cress is great for a fun, fast, educational gardening project. Cress is inexpensive, easy to grow and a fantastic way to teach children about germination and the conditions needed for healthy plants to grow. We grew our cress caterpillar in an egg box and watered the seeds a little each day. How to grow…
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…
