The Queensland Rocketry Society's Ari Piirainen demonstrates how hobbyists build and launch rockets, explaining how to get started with a kit, what the different motor sizes are, and how launches are conducted safely.
Junior scientist Braeden shows us how to build an anemometer and begin collecting data about the speed and behaviour of wind moving around your house or school. Did you know anemometer design has stayed relatively the same since its development in the 15th century? To build this weather instrument yourself, you will need four small paper cups, cardboard, scissors, a ruler, a stapler, a thump tack, some modelling clay, a permanent marker and a pencil with an eraser.
Junior scientist India teaches us about different Australian animal noises. From territorial koalas and chatty dingo packs to the lyrebird's perfect echoes, India demonstrates how to identify each sound and what they're likely to mean.
Junior scientists Josephine and Philippa demonstrate how to test your friends' fungiform papillae concentration and determine who amongst them is a super taster. Fungiform papillae are mushroom-like bumps capped with tastebuds on the tip and sides of our tongues and help distinguish the five tastes: sweet, sour, salty, bitter and umami (savoury). To start testing, you'll need blue food dye, a cotton tip, a bowl, a card with a 7mm hole punched out and a pad for recording results.
Join junior scientist Elizabeth as she demonstrates how to make a colour-mixing wheel. To make your own spinning colour illusion, collect some cardboard, scissors, glue, string, red, blue and yellow markers and a pen or a computer.
Junior scientist Hayley demonstrates how to make a lava lamp using a clear drinking glass, vegetable oil, salt, water and some food colouring. Because salt is denser than both the oil and water, dropping it into the cup makes the floating oil wrapped around the particles as they make their way to the bottom of the glass. Once at the bottom the salt begins to dissolve, allowing the oil to move back to the top of the water, creating a fun lava-like reaction.
Junior scientist Lilli demonstrates how to grow your gummy lollies using osmosis. To do this experiment at home, you'll need some gummy lollies, three bowls, water, sugar, a pen, a rule and some paper for recording your results. Did you know that osmosis is the movement of solvent molecules through a semi-permeable membrane? In this case, osmosis is occurring when the water moves into the body of our gummy lollies.
Scope's resident scientist, Julia, teaches us about the periscope, how it works and how to make one from readily available materials. To build this stealth observation device, you'll need two milk cartons, two small mirrors, a marker, a rule, sticky tape and scissors.
Meet Anzac, the great-great grandson of a World War I soldier at Gallipoli, as he tells us about the inspiring man he's named after. The elder Anzac actually lied in order to be able to serve in World War I and he was eventually killed fighting for Australia. Now, we celebrate Anzac Day to remember those who died serving their country.
Learn about the relationship between art and identity from Larrakia (Darwin) elder June Mills. From screen-printing to traditional techniques and materials, June Mills explains how every nation has its own stories, designs, and ways of sharing knowledge.
Queen Elizabeth II recently set a record as the longest serving queen and quite a lot has happened through many years of service. Find out how her power and position has changed through the years and the ongoing debate about whether or not she should still be Australia's queen.
Chihiro's father makes reference to the "abandoned theme parks" built in the 1990s after they stumble into the new world. Hayao Miyazaki's films make continued reference to the destruction of the environment through human interference and industry.
Join junior scientist Ana as she guides us through building a small-scale hydroponic system for growing herbs and salad greens. All you need to follow along is a 2L soda bottle, string, perlite (amorphous volcanic rock), hydroponic fertiliser, the seedling you'd like to grow, and sunlight. Using a hydroponic system substitutes soil for a nutrient-rich water-based solution that allows the plants to photosynthesise efficiently in a compact environment.
Junior scientist Caleb shows us how to make a simple device to measure rainfall. You'll need a 2L plastic bottle, modelling clay, a ruler and a maker. Measuring rain helps us understand seasonal changes, provide better forecasts and study patterns in our weather. The Bureau of Meteorology (BoM) is Australia's national weather, climate and water agency. By measuring rain, the BoM can tell us about rainfall across the country and assist Australians dealing with drought, floods and storms.
Watch as junior scientist Joel teaches us how to explore the stars using a constellation geoboard. To begin your stargazing adventure, you'll need a constellation template, a round cork trivet, glue, ball-head pins and a few rubber bands. Only Orion, located on the celestial equator, is visible throughout the world, so when making your own geoboard remember to choose a constellation template that matches your hemisphere.
Junior scientist and physics buff Kristopher demonstrates why two conical funnels roll up hill when placed on fanned rails. To get started, you will need two medium funnels, two rails, duct tape, a box and a few books.
Creative junior scientist Kate shows us how to make outdoor foam paint using a simple starch and household polymers. To make your own set of paints, you will need washable school glue, white flour, white shaving foam, food colouring, a large plastic zip bag, sandwich-sized zip bags, and scissors.
The students at Westminster Independent School investigate different sail designs to determine the most reliable shapes and materials. Breaking up into three groups, the students begin by testing what shape provides the most propulsive force and then experiment with different materials to find the combination that is the most effective tensile structure. To carry out your own tests, you'll need a 1L milk carton cut in half, scissors, plasticine, straws, and a variety of materials for the sails.
Junior scientist Lilli demonstrates how engineers investigate the structural integrity of buildings by using a shake table to test stability (seismic performance) during development. To build your own shake table and start testing, you will need a binder, scissors, rubber bands, a pen, bouncing balls and Lego blocks, or similar building materials.
Junior scientist, Carrick, demonstrates how to make green eggs using red cabbage. Sound impossible? Carrick also explains the chemical reaction behind these colourful eggs and how to make other colours with the anthocyanin in red cabbage. To make your own egg creations, you will need eggs, a half red cabbage, a sieve, a bowl, a frying pan, butter, a knife and a chopping board.
Everyone has different tastes in music so it's hard to narrow down one genre as the most influential, but scientists have attempted to do that by analysing US music charts from 1960 to 2010. During that time, they've determined that no other genre of music has been as influential as hiphop in changing the landscape of music and impacting all sorts of artists. Hear more about their findings and meet some hiphop fans who explain why the music means so much to them.
