Dylan gives Lotus a VIP tour of Lexicorp's state-of-the-art facilities. On the surface, she's here to buy stuff, but secretly, she's investigating the link between Lexicorp and the missile launch! This lesson will apply acceleration-time graphs to represent motion. Show Less

The royal archery contest begins! Everyone expects Robin Hood to win since he is an accurate and reliable archer. But what do the terms accuracy and reliability mean? This lesson will take an in-depth look at accuracy and systematic errors, including how to assess and improve the accuracy of experimental results. Show Less

The cunning Carmen breaks into a jewellery store and steals $5 million in diamonds! Vector Man can't help because he is crippled by hunger. Will the police be able to catch her? This lesson will outline how to convert between graphs of motion by calculating areas. Show Less

In a repeat of the failed dinner date at Hopeless Ramentics, Mark Brent leaves Lotus to stop a robbery and save the day! That is, until he falls prey to his ultimate weakness! This lesson will introduce how to convert between graphs of motion, focusing on relationships involving gradients. Show Less

We've all heard the saying, “what goes up must come back down.” But when we launch rockets and satellites into space, they (usually) don't come back! Let's prove this saying wrong, using Physics! This lesson will introduce and derive the equation for escape velocity. Show Less

Gravity is a heart-warming story of attraction. These farm animals would fall for each other even if the laws of Physics stop working! This lesson will formally revisit the gravitational force (from year 11), focusing on Newton's Law of Universal Gravitation. Show Less

The results are in - gravity is weaker than it should be! Lotus is certain that someone is digging a giant cave underneath the Big Apple, but Mark isn't convinced. Who do you think is correct? This lesson will assess the accuracy, reliability and validity of the experiment to measure the acceleration due to gravity performed in the previous lesson. Show Less

Black Friday is normally celebrated with sales and shopping sprees, but this year, someone is tinkering underground. Will Mark, Georgie and Lotus discover Lexi Luthor's lair? This lesson will introduce a simple experiment to measure the acceleration due to gravity. Show Less

We know that Robin Hood is an accurate and reliable archer, but just how good is he? Is his aim god-like, or is he subject to the errors and imperfections of mortals? This lesson will continue investigating the concept of reliability, including random errors, outliers and methods of improving the reliability of experimental results. Show Less

Exam tip: one mark in Physics exams may come from using the correct units. So, if you write and use SI units in all calculations (a pretty simple task), you'll get a free mark! If only the rest of the exam was that easy! This lesson will continue our crash course on units in Physics, focusing on SI prefixes and simple unit conversions. Show Less

The Ancient Greeks believed that everything is made by combining four elements: earth, water, air and fire. It turns out that there's actually seven elements in science - watch this video to find out what they are! This lesson will introduce the fundamental and derived SI units used in Physics. Show Less

The archery contest has a long list of rules, but Chelsea the Cheater keeps breaking them! How does this affect the outcome (conclusion) of the competition? This lesson will begin our analysis of validity by examining the importance of the independent, dependent and controlled variables of an experiment. Show Less
