What is Perimeter?
The total distance around the outside of a two-dimensional shape
What is the mode of a data set?
The number or value that appears most often.
What is my favourite breed of dog?
German Shepherd
What is a force?
A push or a pull.
What is a mixture?
A combination of two or more substances that are not chemically joined.
What is area
The amount of space inside a two-dimensional shape
What is the median?
The middle value in a dataset when all the numbers are arranged in order from lowest to highest
What is my favourite christmas movie?
Elf
What force slows down moving objects when they rub against a surface?
Friction.
What do we call a substance that does not dissolve in a liquid?
Insoluble.
What is the Formula for the area of a rectangle?
A = L x W
How do you calculate the mean?
Add all the numbers in a data set together and then divide that sum by the count of the numbers in the set
What date is my full Birthday (dd/mm/yyyy)?
25th August 1998
If forces on an object are unbalanced, what will happen to its motion?
It will speed up, slow down, or change direction.
What separation method would you use to collect clean drinking water from muddy water?
Filtration.
What is the formula of the area of a triangle?
A = 1/2 x B x H
Find the Mean of the following data set:
2, 5, 3, 8, 10, 2, 9, 1
The mean in 5
What is my favourite band?
Blink-182
A box does not move when a student pushes it with 50 N of force.
Explain why using the idea of balanced forces.
The forces are balanced because friction pushes back with an equal force (50 N), so there is no net force and the box doesn’t move.
Which separation technique is used to separate a soluble solid (like salt) from a liquid?
Evaporation (or crystallisation).
A tringle has a base of 3m and a height of 4m. What is the area of this triangle? (Make sure your answer is complete).
6m^2
Calculate the Median of the following data set:
7, 4, 6, 1, 2, 8
The median is 5
What year did I move to Adelaide?
2018
A skydiver falls through the air and eventually reaches terminal velocity.
Explain what this means in terms of forces.
Air resistance becomes equal to the force of gravity, so the forces are balanced and the skydiver stops accelerating.
A student wants to separate sand, salt, and iron filings from a mixture.
List the correct order of separation techniques.
Use a magnet to remove the iron.
Add water + filter to separate sand.
Evaporate the salt solution to collect the salt.
