Pendulums

 Such great fun with pendulums. Changing the mass or pushing it harder or softer has no effect on the Period. Changing the paths from back and forth to more elliptical also has no effect, only changing the length makes a difference.

Electrolysis

Time in the holidays to go over some of the required practicals like electrolysis. We can spend some more time repeating the experiments and making sure that they are thoroughly understood @ Hemel Private Tuition

 

Resistance and length of wire

10 minutes to do a required practical measuring the length of the resistor wire using a @pascoscientific ultrasonic Motion sensor and the voltage/current sensor linked to Capstone to work out the resistance and plot the results.@Hemel Private Tuition

 

The functions on a Calculator

 These are two popular A-Level Calculators, but how many students need to learn many of the functions? Most I meet need to learn about the memories, the ENG function, how to get improper fractions as answers or know of the other log button and that's just the 991EX calculator. https://hemelprivatetuition.co.uk/

Centripetal force

 An A-level online practical with me doing the dangerous part.Investigating how the force varies with speed for a fixed radius and mass. https://hemelprivatetuition.co.uk/

Pond

 One of the advantages of having a Pond is the abundance of life we can see down the microscope. Duckweed is my major problem and keeping the pond healthy so all types of creatures can inhabit it. https://hemelprivatetuition.co.uk/

Hashing

 Hashing - a black art of storing lots of information in a little space so the information is quick to access. Theory is one thing but trying it out and building a system explains how and why it works. https://hemelprivatetuition.co.uk/
