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.

 

Fizzy Lemonade equilibrium

I measured and recorded the change in pressure using the @pascoscientific Chemistry sensor of some lemonade poured into a sealed flask. Initially, the pressure increased rapidly, but then as the pressure increased, less CO2 came out of the solution, creating a dynamic equilibrium.

 

Maths and Physics

 Maths and Physics. Should one be advised to take one with the other? The students without Physics struggle with Mechanics, and the Physics struggle without solid Maths knowledge - for them, maybe A-level Further Maths would help.

Measuring Friction

 A Newton spring meter measured the force of friction exerted by some books on a table. It shows how hard someone has to push to overcome friction—unbalanced forces.
