National Science Week is Australia’s annual celebration of science and technology. View resources and information on Science Week here!
A collection of science resources and activities to try at home with little ones to spark creativity and problem solving, and encourage STEM learning.
Science activities can be very engaging for kids but may feel daunting if you are trying on your own for the first time. With STEM (science, technology, engineering, and mathematics) being incorporated into curriculum, it is important to bring this learning into a child’s home too.
We have created six fun and EASY science activities using common or easy to find household items. You can download the activities by clicking through the links on the images below.
This activity teaches children about sound. The vibrations of the string, caused by movement, travel along the string and are amplified by the hollow cup, which acts as a sounding board. If you cover the open end of the cup, the vibrations from the string are almost silent = no sound).
This activity teaches kids about reaction. The baking soda is a compound called sodium bicarbonate. The vinegar is an acid. When they get mixed together, they react to produce carbon dioxide gas (hence all the bubbly). The detergent helps to trap the bubbles created by the carbon dioxide, so you get much better ‘lava’ from your volcano.
Recycled crayons teaches children about the phases of matter. By heating the crayons, you can change their state from one form to another. Once cooled, the forces are strong enough to hold the particles together again to make a solid. The crayons start out as a solid, the heat melts them into a liquid, then they return to their original state as they cool.
Stringed instruments make a sound when their strings vibrate, that’s why you need to pluck the strings of a harp to hear the notes. The strings make different notes depending on their thickness, the amount of tension they’re under and their length. The sound hole helps to make the sound louder by amplifying the vibrations and allowing the top of the shoebox to vibrate slightly. The pencil raises the strings off the lid so they can vibrate more freely.
This activity educates children on energy transfer. When you pull back the rubber band, you transfer energy to it. The rubber band stores the energy until you let go of it. Once you let go, the rubber band transfers energy to the marshmallow to make it fly through the air.
Here, we learn about oxidation. When you draw your map or message, the lemon juice is absorbed into the paper. By heating the paper, you create a chemical reaction that releases a chemical element called carbon in the juice. When the lemon juice comes into contact with air, and is heated, it turns brown as carbon is released – a process called oxidation.
We hope you enjoy trying these out! What are your favourite science experiments to do?
Is science not for you? How about trying out some of these awesomely engaging edible activities!
We all know our special little ones are creative little geniuses. They’re always experimenting with something so we’ve found some pretty mind-blowing and hands-on science experiments that you can do on your weekly visit with them. Best of all, they all use things you probably have lying around at home.
We feel these super-easy science activities are a great way to spend quality time together where the little ones are exposed to a wide variety of scientific concepts.
Learn about surface tension with this fun experiment. This is possibly the easiest and most beautiful science experiment out there!
What happens when you mix peroxide, food colouring, water, dish soap and yeast and wait for two minutes? You get elephants toothpaste!
Talk about a groovy project! This fun science experiment is sure to impress – make a lava lamp by pouring vegetable oil into water, then sprinkling salt on it to make the blob of oil move.
Learn how to make a cloud in a bottle, instantly! If you’ve ever wondered how real clouds work, try this experiment.
Who doesn’t like to pretend like they’re a secret agent? Write secret messages to your friends and try to get them to decode them. The trick? Holding it close to any source of heat – like a candle or incandescent light bulb.
This is a super fun way to show the kids how primary colours mix to form secondary colours. Because water and oil don’t mix, the kids can see how the primary colours separate back after they’ve been mixed around. For this fun project, we use water which is coloured by regular food colouring and baby oil which is coloured by oil-based food colouring.
Making rock candy means the little ones can actually see the shape of tiny little sugar crystals on a magnified scale. Giving them lots of time to grow means they’ll form much bigger! you can eat these pretty little things once they done or you can keep them. What a yummy and beautiful experiment!
We had no idea that electricity and magnetism were so closely linked! You can build your very own miniature electromagnetic train by experimenting with the two materials.
Thought you could never stand on top of The Big Banana or ride The Big Cassowary? Well, you can make anything look possible with forced perspective photos!
Gather some of the kids favourite toys, plus things from around the house and garden and have the kids guess whether they object will float or sink.
How cute are these eggheads? Plant grass seeds in an empty eggshell and watch their hair grow! You should see sprouts in a few days that you can style any way you want.
