5 Outdoor Science Experiments Well Worth a Try

5 Outdoor Science Experiments

Make a smoke bomb

This is brilliant fun and the kids will love it although it is probably best with the slightly older ones. You will need some sugar, some potassium nitrate (which you should be able to pick up from the garden centre), an old pan you don’t mind ruining, a long candle, some goggles and a fire glove. Weigh out 60g potassium nitrate and 40g of sugar and place them in the pan together. Place the pan over a hob on a low heat and bring it to the boil, stirring to avoid it burning. Once the mixture is a liquid brown it is ready. Head on outside with your safety goggles and your fire glove. Place the mixture in a safe place such as on a wooden table or in a clear area on the floor. Using your gloved hand light the candle and use this to ignite your mixture. Once the mixture catches it should start to smoke and will keep going until it has burnt off. Step back and enjoy the show. Once it is done then leave the pan to cool before you attempt to pick it up as it will still be quite hot.

The good old Coca Cola Volcano

This is so simple but kids always love it. It even works with littlies who are overawed by the results. All you need is some diet coke and some Mentos. Pop one or two Mentos into the Coca Cola stand back and watch the fizziness explode.

Turn water into ice with a bang

This experiment is only for the patient but the results are well worth the wait. It is also perfect to try outdoors at this time of the year while the weather can help with keeping the temperature low. The long wait just gives you the perfect excuse to play outdoors while you are waiting – http://www.bbc.co.uk/bang/handson/super_cool.shtml

Create your own homemade bubble solution

For this one you will need water, washing up liquid and some glycerine and whatever additional ingredients you want to try such as food colouring and gelatine. Experiment with different amounts of each ingredient until you find the perfect recipe. Once you have it then write it down and you will never need to buy another pack of bubbles again.

Create a film canister rocket

You will need an empty film canister, some baking soda and some white vinegar. Some goggles might be useful just to be on the safe side. Put a spoonful of baking soda into the canister and then add some white vinegar. Quickly add the lid and place it lid side down on the ground. If you get the timing right your pot should rocket up into the air making a loud pop. Experiment with different amounts of baking soda and vinegar to find out which recipe shoots the rocket the highest.

Want to know how all the experiments really work? Spend some time using your tablet or smartphone to discover the science behind the reactions. In the process your kids will learn how to discover the answer to their questions, learn which sources are trustworthy and which aren’t and build on their scientific knowledge. If you want to extend it even further you could even ask them to show their friends or someone in the family the experiment asking them to explain how the reaction works.
