We spoke to Dr Bobby Cerini, director of Science and Learning, and Angela Stoddard, Learning Programs coordinator from Questacon about easy science experiments that you can do at home.
Make a non-toxic slime by mixing cornflour and water together. You can also add food colouring to the mixture.
"What is really fascinating about this cornflour slime is that acts really strangely," Dr Cerini said.
"If you apply a hard or fast force to it the slime behaves like a solid. If you try to throw it from a bowl it wont go anywhere but if you pour it slowly it will flow and behave more like a liquid."
Take a container of water and a small light object such as a bread tag. if you place the object flat on the surface of the water it will float.
"If you tip it in it will sink" Ms Stoddard said. "But you can also convince it to just balance on the surface of the water just with surface tension"
"It's a really cool phenomenon, you may have seen it if you've seen a little spider or bug walk on the surface of the water."
Dr Cerini recommends collecting seeds and then classifying them at home.
"Science relies on classification to find out what things are and how they are likely to behave," she said.
"You can order them by colour, shape, if they look like they can fly - you can check by throwing different seeds off your stairs and seeing how they fall."
Kids can learn more about the internal systems in plants by placing a flower with its stem into a glass of water with coloured food dye. After a few hours the Xylem of the plant will be coloured.
This experiment also works well with celery.
"You'll soon see the food colouring move through the internal structure of the plant," Dr Cerini said.
"If you are using a flower you can see the colour go into the flower."
Create your own density column using liquids at home such as honey, water, oil and detergent, by pouring them gently into a jar.
"You can investigate how [the liquids] separate, you can play with things like what if you put them into the glass in a different order, or what might happen if you tried shaking the glass," Ms Stoddard said.
"You can extend it by adding in other objects into the column and see where they sit."
While Questacon is currently closed to the public due to COVID-19, the website remains open with resources for kids, teens and families.
"We've created a whole series of activity sheets that parents can download," Dr Cerini said.
"Those sheets come with a resource sheet for parents, so parents will know the answers in advance"
Questacon has a range of educational and instructional videos available that suit children from kindergarten to high school. These include DIY experiments, science talks and stories.
Despite being closed to the public, Questacon is making new additions to their displays.
"For Earth Day, we will be launching our new live beehive," Dr Cerini said.
"We will also be launching our new bees webpage, with lots of interesting facts about bees coming up."
"This is something visitors can look forward to when they can come back to Questacon."
