Friction and Forces

 


#GCSE #Physics Looking at forces. A box is filled with some mass to make it heavy and then pulled across a surface. What happens if we put more elastic bands on, does it get easier or harder to pull. What happens if we spill oil or water on the table does it get easier to pull? #iteachphysics

New Tension Protractors


Two @pascoscientific tension protractors arrived today from @SciChemEdu I was a little surprised when they came unexpectedly. Been trying them out. Hopefully this will make forces and moments easier for my students to visualise and understand. #iteachphysics 




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.


The announcement of the new UV-Vis spectrometer at https://www.youtube.com/watch?v=14JYAK8Pndo&t=1530s  

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

Doppler Rocket

Demonstrating the Doppler effect with the @pascoscientific Doppler Rocket: As the rocket moves away, students can hear the pitch drop (red s...
