In any sort of creative experiment – like these fun science experiments for kids – the fun is in the putting it all together and seeing how one thing reacts with another. Experimental learning is good for children; it’s a form of organised mischief, allowing them to put different materials together and marvel at how they behave. Spending time on this experiment with bottles will keep kids’ attention gripped and stretch their minds. You end up with a set of colourful and wonderful lava lamps, but the real end product is something less obvious but much more important: your child discovering new things with you.
Bottles of Wonder: A Science Project for Kids
Spending time together making these coloured bottles is a brilliant way to tease out your kids’ investigative skills and to encourage an appreciation of how different materials and objects work when mixed together. All the ingredients for these kids’ projects are simple things you might find around the house. Ingredients:
- Small empty plastic bottles with lids
- A plastic funnel
- Liquid soap
- Syrup (any type of syrup will do)
- Food colouring or coloured powders – any colour you like
Bonus ingredients: If you have any of these additional items, you can add a whole new dimension to this science project for kids.
- Daal or beans
How to make bottles of wonder:
- Fill your first bottle with syrup and leave just a tiny amount of air at the top. Put the lid on, turn the bottle upside-down, and watch how slowly the bubble of air rises to the surface.
- Fill your second bottle with liquid detergent, again leaving just a tiny amount of air, and put the lid on. Watch how the air moves much faster through the liquid soap when the bottle is turned upside-down. Avoid any waste here by pouring the detergent back into its original container to use when you need it for the laundry!
- Fill the third bottle three-quarters full of water and add a couple of drops of food colouring. Now fill it to the brim with oil, and put the lid back on. Watch how the bubbles form when you turn over this bottle. The oil forms the bubbles this time as it doesn’t mix with the water.
- Extend these cool science experiments by adding glitter, sequins, or lentils to your bottles. What happens when you turn the bottles over now?
The Benefits of Science Projects for Kids
Experimental learning is great for your kids’ development. Through all these processes, encourage your kids to describe and explain what’s happening in each bottle, and the differences between each one. This will help them articulate their curiosity and learn about scientific concepts such as viscosity (how ‘thick’ a substance is) and density (whether substances float or sink in the water). With just a few readily available materials and old bottles, you can create a science project for kids that will help them understand about different sorts of materials. As they wonder at what’s happening in those bottles, their minds will stretch and open up to the broader wonders of the world.
Stain Removal Tips for Science Projects
You would have noticed quite a lot of things on the ingredients list that might find their way onto kids’ clothes. Don’t worry; just be prepared in case it happens! Sponge off any syrup and liquid detergent with warm water immediately, and wash it later with your normal detergent. Vegetable oil is a little trickier. Try rubbing talc into the fabric, then leave it for 30 minutes and brush it off. You can always look at our stain removal tips .
Remember, if you do end up with spillages, the fun you’ll be having with these cool science experiments along the way will make it all worthwhile!
