As all the animals migrate south to avoid the colder weather, Manny the lonely Mammoth heads against the current. Sid the giant sloth, who slept through the start of the great migration, gets himself in trouble with two shovel-nosed rhinos. In an attempt to escape the angry rhinos, Sid hides behind Manny, who becomes his unlikely hero. Meanwhile, a family of Neanderthals celebrate a new child as a pack of Sabre-toothed tigers watch on, plotting their revenge.
Manny, Sid, Diego and baby Roshan set up camp for the night. Two members of Diego's pack visit him while the others sleep, sending a threat from their leader, Soto. Sid uses the baby to impress two female sloths but gets himself into the usual trouble. The four set out towards Glacier Pass, taking on different familial roles and finding humour in friendship.
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.
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 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.
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 Bella demonstrates how to upgrade your regular toy car by turning it into a mobile electric vehicle. To build along, find a toy car with plenty of space underneath, an AA battery pack with wire connections, a small piece of rubber or an eraser, scissors, double-sided and regular tape, a paper clip and a small electric motor.
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 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.
Sally and Conrad return a purple tornado to a crate, hoping it would restore the damaged house, but the building falls apart. The children are upset when Cat takes credit for containing the twister. Conrad tells Cat there has to be limits to their fun. The two kids tell Cat it's time to get out of their house. Looking around, Conrad decides to take the blame for the damage, but Sally stands by his side telling him to share the burden. Learning their lesson, Cat returns to fix the house.
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.
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.
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.

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.
