Core Skills Analysis
Science
- BJ investigated how surface type changed the bounce of a large and small bouncy ball, showing an understanding that physical conditions can affect motion.
- He repeated each drop three times, which helped make his science test fair and his results more reliable.
- BJ observed, compared, and described patterns in the bounce heights, building skill in using evidence to explain what happened.
- By testing a cardboard car with different weights, BJ explored how added mass can change movement and speed.
Maths
- BJ calculated the mean bounce height and mean speed, showing he could use averages to summarise repeated data.
- He recorded results from multiple trials, which required careful number handling and organised data collection.
- BJ compared sets of measurements across different surfaces and weights, practising how to read and interpret numerical patterns.
- His work connected maths to real experiments by using numbers to support conclusions.
English / Literacy
- BJ followed and carried out a sequence of investigation steps, showing he could understand procedural instructions.
- He recorded observations clearly, which supports the development of concise scientific writing.
- BJ used evidence from his tests to explain conclusions, a key skill for giving reasons and justifying ideas.
- The activity strengthened his ability to organise information in a logical way for others to read and understand.
Tips
To extend BJ’s learning, he could try changing one factor at a time in a new fair test, such as using different ramp surfaces or different ball materials, and predict what will happen before testing. He could also make a simple results graph to compare averages visually and talk about which change had the biggest effect. For a hands-on connection, BJ could design a paper or cardboard ramp and test how slope affects speed, then explain the results in his own words. Finally, he could write a short “scientist’s report” with a question, prediction, method, results, and conclusion to strengthen his science communication.

Try This Next
- Make a results table for BJ’s ball bounce test and car test, then add a bar graph for the averages.
- Write 3 prediction questions: Which surface will give the highest bounce? Which weight will make the car slowest? Why?
- Draw a labelled diagram of the cardboard car and circle the variable being changed in each trial.
- Create a short quiz: fair test, mean, variable, observation, conclusion.
