Using a conductivity sensor

 The students used the @pascoscientific wireless conductivity sensor to help test whether the water samples were safe to drink. The meter was used in a range of tests and quickly identified seawater, brackish water, and tap water by their levels of conductivity.

Mechanics The Canon Problem

 Working out the range of a canon on a cliff, firing at an invading fleet of ships. SUVAT comes to the rescue.

Frictionless collisions

 Investigating frictionless collisions with these hover balls. Students were able to investigate hitting one hover into another at different positions to see the angle it made on the other ball.

Root Tip Squashes

Preparing Root tip squashes by breaking down the cell walls then staining the tips and then looking at them under the microscope to see if we can find any stages of mitosis.

 

Spintronics

 Spintronics: Demonstrating how electrics could work in another way to the students. Some find this helpful as another way of looking at the system.

Building a computer

 One of the best ways to learn about the parts and functions of a computer is to build one. Starting with a case, the motherboard is installed along with the processor and RAM then the hard disks and other peripherals are added.

Metal Sulfate Reactions

Comparing predictions with reality. Allowing the students to design their own experiments. Some worked. It took a lot of work to see the results of most reactions that should have worked because of the small amounts used.
