Muscle strength is shown by how well a muscle can withstand a force or pressure.

To record information is to keep it, so that it can be passed on to others.

A review is the act of considering something again in order to make changes to it, give an opinion of it, or study it further.

Scientists look for patterns in data to answer their questions.

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

In The human skeleton and muscles unit, pupils learn that humans and some other animals have skeletons and muscles for support, protection and movement. In The human digestive system unit, they will build on this knowledge to describe the basic parts of the digestive system in humans

In the Human body parts unit, pupils learnt to describe and compare the structure of common animals and identify and name the basic parts of the human body. In this The human skeleton and muscles unit, pupils will build on this knowledge to identify and name some common bones in the human skeleton

This unit explores the role of skeletons and muscles in humans and other animals for support, protection, and movement. It involves setting up practical enquiries, making observations, measuring accurately, recording findings, and using results to draw conclusions and suggest improvements.
