In this lesson we will learn how to substitute numbers into more complicated formulas. Rob uses real formulas and real examples from Science in this lesson. This lesson takes you to New Zealand where you will see Dolphins chasing boats and jumping out of the water, Mt Everest on a very cold day and to the Eiffel Tower in France.

The questions covered in this lesson are all real equations and real life examples: i) Using the formula $KE$ = $\frac{{mv}^2}{2}$, find the kinetic energy, $KE,\ $of a dolphin with a mass of 300kg and velocity of 15m/s. ii) Using the formula $F$ = $\frac{9}{5}^\circ{C}$ + 32, a warm day on Mt. Everest is -$10^\circ{C}$, convert this temperature into Fahrenheit. iii) Using the formula $t$ = $\sqrt{\frac{2h}{g}}$, calculate the time it takes a 2 pence to fall from the Eiffel Tower, $h$ = 325 and $g$ = 9.8

In this lesson we will learn how to plot any straight-line graph from a table of values. You will learn tips on accurately plotting your points and how to avoid common mistakes often made by students when drawing graphs.

The questions covered in this lesson are i) plot the graph of $y$ = 2$x$ +1 ii) plot the graph of y = -3$x$ + 5

There are 2 methods for calculating the average speed from a distance/time graph.  In this lesson you will learn the first of these methods.  Make sure that you also watch part 2 of this lesson to learn the other method.

Thousands of students every year make this common mistake involving time when answering speed/distance/time questions.  Rob will show you how to get your questions correct everytime.  

In this lesson we will learn the second method for calculating the acceleration from a v/t graph.   You must be able to calculate the gradient of any straight line graph before trying this lesson.  If not then watch the following lesson in Algebra:  Finding the gradient of a line.

In this lesson we will learn how to calculate the total distance travelled from a velocity/time graph.  You must be able to calculate the area of a reactangle, triangle and trapezium before trying this lesson.  If not then watch the following lessons in Geoemtry and measures:  Calculating the area of a rectangle and/or calculating the area of a triangle and/or calculating the area of a trapezium.  

In this lesson we will learn what a prism is and the meaning of the term cross sectional area (C/S area). Rob uses different 3 Dimensional cakes and shapes to teach this lesson in a unique and fun way. We will also learn the formula for calculating the volume of any prism and all of the different shapes that are prisms. This lesson will make finding the volume of most shapes very easy. But again this lesson was just an excuse for Rob to eat his favorite cakes.

In this lesson Rob takes you to the great pyramids of Egypt where you will learn how to calculate the volume of a square based pyramid. You will also learn how to complete more complicated questions which will require calculating lengths using 3 dimensional Pythagoras. 

In this lesson we will learn how to find angles on parallel lines using the rule of alternate angles and you will learn how to gain full marks when answering these types of questions. This lesson has specially edited using special software so that there is a section in the middle of each example where the alternate angles and the lines that make those angles are highlighted in bright red. This makes them stand out so that you can easily see where they were hiding amongst all of the other angles and lines. Because of the way this lesson is edited you will find this lesson very easy to learn.

In this lesson Rob travels to Egypt where he will teach you how to calculate angles inside the great Pyramid of Giza. Rob also uses real 3D models to help you visualise the 2D triangles inside the pyramid that you will need in order to solve these 3D problems.

You must be able to calculate angles using Trigonometry before trying this lesson. If not then watch the following lessons: Finding an angle.

This this lesson we learn how to round numbers to a certain number of significant figures. Only large numbers bigger than 1 will be covered in this lesson. It would help if you are able to round to decimal places before trying this lesson as there are similar rules in both of these topics.

The questions covered in this lesson are i) round 376900 to 2 significant figures (2S.F) ii) round 504120 to 3 significant figures (3S.F) iii) round 87430 to 1 significant figure (1S.F)
