In this resource students explore how an electromagnet works in real life. They can then apply their learning in an electromagnetism game by changing the magnetism of a scrap lifter in a scrap yard and removing various amounts of scrap. The resource demonstrates the connection between the power applied, the number of coils ...

Watch scientists investigate water movement through soil that has been cracked by drought. Australian scientists demonstrate a new way to investigate how water moves through the cracks using electrical probes to measure soil moisture at different soil depths. This technology could help farmers more efficiently irrigate ...
