Here at Science Sparks we LOVE a good science fair project but appreciate that not everyone feels the same way, so here are a few great science project ideas to give you some inspiration.
Messy Science Fair Projects
Why is slime slimy?
Find out why slimy has the properties that make it fun with a slime investigation using our easy slime recipe.
Make a soda dispenser
First up is this AWESOME soda dispenser idea from Steve Spanger using the old mento and soda trick. You could use the activity to investigate how different types of sodas have different levels of reaction, and challenge yourself to see how many cups you could fill.
Erupt a volcano with baking soda and vinegar
Learn about chemical reactions with a baking soda volcano. Experiment to find the perfect combination of vinegar, baking soda and washing up liquid ( dish soap ) to make the most realistic looking lava. Does thicker lava flow more slowly?
You could make a volcano from papier mache, modroc, sand or snow! Try making different colours, sizes and shapes.
Babble Dabble Do has an amazing lemon volcano that we bet will smell amazing too!
Weather Science Fair Projects
Track changes to the weather over a period of time by making a barometer to measure air pressure, a rain gauge to measure rain a pinecone weather station and other fun weather science activities.
Food Science Fair Projects
Why does fresh pineapple stop jelly setting?
Try some kitchen science and investigate why fresh pineapple stops jelly setting. You might find some other fruits have the same effect…
Density Science Fair Projects
A density jar makes for a wonderfully visual science demonstration. See how many layers you can float on to of each other and try to find an object to float on each layer.
You could even try a little science magic trick. Although this can get messy so be careful.
Use eggs to investigate osmosis and diffusion.This simple, low cost activity is great for explaining quite complex processes and very visual as well.
The photo below shows how water has moved into one egg ( with the shell removed ) and out of the other.
