What you want to do | How to do it |
start/ restart the simulation | Click on the "Reset Setup" button. Tick 'Enable Data Logger' |
set the number of coils around the electromagnet | Click the slider found beside the words "no. of coils = 3" in the dark grey cell on the top left corner of the simulation. The number of coils in this simulation ranges from 3 to 9. |
set the number of batteries | Click the slider found beside the words "no. of batteries = 2" in the bright green cell on the top right corner of the simulation. The number of batteries in this simulation ranges from 1 to 5. |
start the electromagnet working |
click the "Play" button or click on the "switch" in the circuit diagram to close the circuit. |
to find out how many paper clips the electromagnet can attract | drag the electromagnet downwards into the tray of paper clips and drag it back up. The number of paper clips attracted will be automatically recorded in the data/ results table. Ensure the 'Enable Data Logger' is ticked. |
restart the electromagnet to change the variables |
Click "Reset Setup" to open the circuit. After you change the variables, click the "play" button again.
|
clear the data/results table and restart the collection of a new set of data.
|
Click "Reset Table" |
Sample Learning Goals
Pre-requisite Knowledge: |
Students should already know:
|
Recommended Lesson Duration: |
2 to 3 one-hour lessons excluding offline learning
(students may be still grasping the concept of variables so time is factored for teachers to address the gaps before students proceed.)
|
Learning Issue to be Addressed: | Students have difficulty in appreciating the importance of variables in a fair experiment. |

From Teacher: 20210801
I used the virtual electromagnet experiment you created for SLS. [The simulation is]very good. I got the students to do the 2 experiments for changing the number of coils and number of batteries. I realized that they changed 2 variables [and] anyhow did [it]. Today get them to redo and snip it to submit it to me for monitoring.... so much better. I like this [this is] because [it is usually] very difficult to do a real experiment to see the trend. Thanks so much! Attached a sample of students' work.
