MAGNETIC CRANE - GRADE 7 MINI-PAT - Face to Face

Outcomes of Workshop

This workshop will enable you to:

• Recognise the different types of magnets
• Conduct experiments to find out which substances stick to a magnet
• Conduct tests to determine which metals are attracted to a magnet, and which are not
• Demonstrate a simple electric circuit with an energy source (cell), switch, conductor and a light bulb or buzzer
• Sketch the circuit showing how to use component symbols
• Make a simple circuit as demonstrated
• Draw the circuit using correct symbols for components
• Make a simple electromagnet by winding insulated copper wire around an iron nail
• Write a design brief with specifications and constraints for a crane with an electromagnet
• Use an electrochemical cell, a switch, a light bulb, a ‘soft’ iron core and a long length of insulated copper wire to make an electromagnet
• Make a model crane with a crank-and-pulley system which will carry the electromagnet
• Develop a rubric to evaluate the models of other teams
