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.

Calculating KE

 Putting a formula into @pascoscientific Capstone, running the experiment, and live plotting the data from the equation. Using the smartcart at the end of a spring the students were able to calculate and graph the Kinetic Energy in simple Harmonic Motion.

Implicit Differentiation

 Trying to unravel the mysteries of implicit differentiation. Not the easiest of topics, especially when all the accumulated knowledge so far is required to solve and tidy up these equations.
