Calipers

 Ask a student to measure something, and then they will grab a ruler. But sometimes we need to be more accurate, and in comes the Vernier or Digital Calipers, something many have never met before.

Steam generator

 Using a steam generator to heat up a syringe to 100C then injecting a known volume of a volatile substance to see it turn to gas. t takes quite a long time to get everything to 100C but the results are worth it.

Resonance Driver Experiment

 We measured the spring and weight moving up and down using @pascoscientific sensors and Capstone. Then we set up a resonance driver and the students had to predict the driver frequencies.

How a slide Rule works

 What are logarithms, how do they work, and why do we use them.? Students learnt that I lived in a time BC (Before Calculators), why I needed a slide rule, and how it worked using two rulers working as a number line. We also looked at log tables. Rather Frightening.

Resonance 2

 How different lengths of metal vibrate at different frequencies and relating this to the driving frequency. Prediction is the next critical stage. Can these be predicted - Yes!

Biology Environmental changes

 Pictures in the news appropriately remind the students of the environmental changes we are looking at in Biology. How climate change is really affecting people's lives in this country.

Making Slime

One of the most fun experiments, that many students have done at home before, but now they learn how it works and why. Many good recipes given and a few failures.
