Little Bang Discovery Club

science at home

Do you have a little scientist at home? Burwood Library brings you Little Bang Discovery Club, a hands-on science discovery program- now available at home online, anytime!


Suitable for kids aged 3-5 years, there are four sessions to watch with your child, each covering a different fun-filled topic. Then use items from around the house to have a go at the activities together.

Getting started

Before starting, we recommend putting together your own Discovery Box, containing the listed or similar items, which you will use during each session. There will also be a list of additional items specific to each session.

In your discovery box you will need:

  • 1x large box or bag to put everything in
  • 1x ruler and/or tape measure
  • 2x timer or mobile phone with a timer or a clock with a second hand
  • 2x plastic cups
  • 2x big rubber bands
  • Approx. 4m of string
  • 1x chopstick or a big spoon
  • 1x notebook or paper

  • 1x magnet or fridge magnet
  • 1x coat hanger. Metal or child size
  • 1x take away box or a lunch box sized container 

SESSION 1: Collecting and Classifying

Being a junior discoverer takes some special skills. In this first session you will learn how to sort and match objects from around the home.

You will need:

  • Approx. 6 pairs of socks, hats, t shirts
  • Approx. 10 small toys e.g. Matchbox cars, small animals, Duplo Lego bricks


SESSION 2: Measuring

In this session we will learn all about weighing and measuring – one of the first and most important skills of early discoverers. Learn how to balance unevenly weighted objects so you can make your own mobile at home.

You will need:

  • Your discovery box
  • Small items from around the house such as cutlery, toys, coins, pieces of fruit
  • 7 pieces of string approx. 30cm long
  • Coat hanger, chopsticks, pencils, pop sticks, and then 7 small toys 


SESSION 3: Experimenting

Today we will ask lots of questions and design our own experiments to find the answers. We put our measuring, observation and recording skills to the test. We will prepare you to undertake your own experiment at home for next week’s science fair.

You will need:

Your Discovery Box

To make an inclined slope: 1× tray or lid of a large box or piece of cardboard or a small whiteboard with one end resting on a box or something similar.

Two or more small wheeled toys e.g. cars

Joys of Attraction: Magnet or fridge magnet from Discovery Box

Musical Coat Hanger: Metal coat hanger and 2 pieces of string approx. 45 cm long. Pencil, pen or teaspoon

Sink and Salt: 3 strips of Blu tack or plasticine, 3 cups with tap water, spoon, (newspaper, towel)

Sink and Float: 1× hard-boiled egg or a grape, 1× plastic bowl, 1× spoon, 2× cups with tap water (can use those in the Discovery Box) and 1/4 cup salt (newspaper, towel)


SESSION 4: Science Fair

In our final session the children will hold their very own science fair, with what they have discovered in their own experiments.

You will need:

Your Discovery Box

Magnifying with a Glass of Water: 1× Glass (made of glass) half-filled with water, newspaper or magazine picture
