Amylase + Starch

 #GCSE #science looking at the reaction of Amylase with Starch. Every 10 seconds we took a sample.

By 30 seconds most of the Starch had gone in within a minute all of it had turned to Maltose. Shows how fast enzymes are. Even better to do this in a spectrometer #biology

A fish fossil under the microscope

 Looking at a fossil fish under the microscope.. A few million years old but the fish hasn't really changed much. The student used a stereo microscope to view the fossil. #FossilFriday #fossil #Science

Ideal Gas Equation

 Working out PV=nRT the ideal Gas Equation in #alevels #Physics from @pascoscientific supplied by @SciChemEdu The Capstone software shows the results quickly and easily so we do these experiments in a few minutes to remind the students before their tests. #iteachphysics

New Spectometer form Pasco

 @pascoscientific just announced their new UV-vis spectrometer. I am still a bit behind with my wired colorimeter supplied by @SciChemEdu a few years ago. Works well and does great expts. Looks like I will need to save up some more pennies.

I find that for many of these new toys and inventions altjhough the students use them a bit, I get more out of them than the students. 

Diffraction Grating

 #alevel #Physics revision Looking at a laser passing through a diffraction grating to determine the wavelength of the laser light. Measuring the angles between the dots, gives an accurate measurement of the wavelength. #iteachphysics

Pinhole Camera

 The bright sunshine is an excellent opportunity to try out the pinhole camera. Many students are amazed to see images with such a simple device. Many thought photographs could only be taken an a several hundred pound smart phone. #iteachphysics

Parallel Springs

 All the students know about Hookes Law and weights on a spring, but much weirder things happen when there are springs in parallel. It is down to the A level students to work this out.
