The surface is the top or outside layer of something.

Friction is a type of force that acts between surfaces.

Variables are things which can be changed in a fair test investigation.

In a conclusion, scientists explain what the results show or mean.

Friction: do and review

Science

In this Forces and simple machines unit, pupils learn that air resistance, water resistance and friction push back against moving objects. In this Forces unit, pupils will build on this knowledge to accurately describe and explain the actions of forces in a range of situations.

In the Simple forces including magnets unit, pupils learnt to compare how things move on different surfaces. In this Forces including simple machines unit, pupils will build on this knowledge to identify the effects of air resistance, water resistance and friction, that act between moving surfaces

Forces including simple machines

Physical activity and equipment requiring safe use

Starting with the least, order these surfaces in terms of the friction they create.

In which part of an investigation should you summarise the results?  

to help them make predictions for further investigations

data showing the relationship between two variables

Which of these data types are best shown in a bar graph? 

What is the name of the force that acts between objects that are moving, or trying to move across each other?

How many variables should you change in a controlled investigation, such as a comparative or fair test? 

If the enquiry question is, “Do different gloves create different amounts of friction?”, which variable should you change? 

Which of these are ways in which scientists present results?

sorting food into healthy and unhealthy groups

measuring the temperature of a hot drink 

finding out which type of paper makes the fastest aeroplanes

Match the investigation type to the activity. 

In which direction does friction act on moving objects?
