Detecting Magnetic Fields

Using a #pasco magnetic field detector and a smartcart to investigate the strength of a magnetic field between to opposite pole magnets. It wasn't quite what we predicted or expected. This was an A level Physics experiment conducted online. Using the capstone software the student could watch the experiment and the display at the same via #blackmagic atem.

Fractional Distillation

 One of the topics covered today was burning crude oil fractions we made to compare for smokiness. Though the #lockdown3 we heated crude oil at different temperatures and collected the fractions and then tested them, the student controlling this and me doing as I am told.

Teaching Online again

 

Well it's back to online teaching - some students never left - It only took a few moments to change back to the Lockdown way of life. The classroom is turned back into a studio with cameras and experiments galore. During our brief respite we added more equipment and resources so we are ready to go.

Using Snatoms to explain solvation

Solvation is one of those very hard topics to understand. We have been using the Snatoms to try and make solvation slightly easier to follow. We can see the idea behind size and how the different molecules can bind to one another. We can show how the shape of the molecules makes a difference. We can then help explain what ligands are and how they make sometimes those really pretty colours.

Terminal Velocity

At over 2m tall this tube filled with water can help work out the terminal velocity of an object as it sinks through water. Using a #PASCO rotary sensory, we dropped a brass weight ( 25g) attached to a piece of string. As the ball fall it turned the motion sensor which in turn recorded the distance travelled, the velocity of the weight and its acceleration.

Measuring Gravity by Free fall

Some of my equipment is very expensive and dedicated to only one job or experiment .Lego EV3 on the other hand can be used with some ingenuity to create many different types of equipment, to record all types of events. Here we are measuring Gravity by free fall and creating this out of Lego can achieve some remarkable results. The time for the drop of 50cm has just over 0.32 of a second giving an estimate of gravity at 9.76 m/s/s. With a bit of programming this is a very decent result and remarkably consistent as well.
