The following strands are covered in this activity:
Description of activity
Students investigate whether some magnets have a stronger pull force than others.
Instructions:
- Students make predictions about how the pull force of different magnets will vary.
- They design and conduct a fair test using a variety of magnets, paper clips and a ruler.
- Students record their results in the grid.
- They comment on the method used in the test, the results, and the accuracy of their predictions.
Suggested materials
Magnets (bar, horseshoe, flat, fridge etc), paper clips, ruler.
Prior learning
This task is a small part of a Science and Technology unit of work in which students have identified and analysed different push-and-pull forces in the natural environment. This activity focuses on students investigating magnetism as a pull force. Students have investigated the different materials that are attracted by a magnet and the teacher has demonstrated the pull force of a horseshoe magnet using a paper clip ‘train’.
Outcomes
Investigating Scientifically (INVS 2.7)
Conducts investigations by observing, questioning, predicting, testing, collecting, recording and analysing data, and drawing conclusions.
Physical Phenomena (PPS 2.4)
Identifies various forms and sources of energy and devises systems that use energy.
Criteria for assessing learning
Students will be assessed on their ability to:
- design a fair test to investigate the pull force of a magnet
- make and record their predictions
- conduct a fair test
- record the results of the investigation
- analyse their predictions.
