# Bone length: review

I can use my results to look for patterns in data, and write a conclusion about bone length.

## Lesson details

### Key learning points

1. Scientists look for patterns in data, to tell them how one thing affects another thing.
2. The conclusion of an investigation is when scientists explain what the results show or mean.
3. Our bones grow in length as we age, until we become an adult.
4. The length of some bones can be used to estimate the length of other bones, and our body height.

### Common misconception

Children may think that bones continue to grow throughout their lives.

Spend time looking at the data they have collected and reinforcing the fact that our bones stop growing when we reach early adulthood.

### Keywords

• Patterns in data - Scientists look for patterns in data to answer their questions.

• Effect - Effect is the change that occurs between two things that we can observe.

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

• Adult - The adult is the mature form of a plant or animal.

• Estimate - An estimate is a guess of what the size, value or amount of something might be.

This lesson is linked to the previous lesson (lesson 3) in this unit whereby children planned and carried out their own bone length investigations. They should use the data they have already collected to look for patterns and write a conclusion.
