Terminal Velocity

https://www.youtube.com/watch?v=35Gl4JAgWuk

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.

A Level Maths Teaching.

 As well as covering the sciences, we also cover Maths at both GCSE and A Level. Many of our students struggle with some of the harder concepts such as Trig Equations and solving them. This weeks A level Maths lesson dealt with this problem showing approaches to solving these problems without resorting to the answers or begin told this is the way to do this one. Students need to learn these techniques so that they can become better

Glycolysis A level Biology

In today's A level Biology Video we looked at Glycolysis, the Link reaction, The Krebs cycle and Oxidative Phosphorylation. The process of Glycolysis breaks down glucose into 2 3 carbon sugars only producing a small amount of energy. The link reaction does a little more, but the Krebs cycle makes the most energy and this is in all forms of energy chemicals. These are all turned into ATP the energy molecules by the process of oxidative phosphorylation.

Transpiration and the Potometer

Looking at how plants take up water is an essential experiment in Biology. A small piece of plant in this case some water cress is inserted into a tube at the top making a water tight seal. The potometer shown here allows an air bubble to be brought into the apparatus, using a syringe, so that the movement of the bubble can be monitored with time. As the plant transpires, water is sucked up the tube and evaporates from the leaves. By knowing the volume of the capillary tube the amount of water lost be minute can be calculated.
