Polarising Filters and a light sensor

 #Physics Two large polarising filters and a @pascoscientific light sensor and rotation sensor looking at how light levels change as the second ring is rotated. Working on the video and calibrating the rotation sensor #iteachphysics

Slow Motion of Acceleration down a track using bells

#Physics Our first attempt at setting the correct distance of the bells to relate time to acceleration using @pascoscientific cart and track from @SciChemEdu and 3d Printed bell holders Here is the #slowmotion #iteachphysics

Prototype bell on a stick

 First prototype of the bell on the stick. The bell rings on the @pascoscientific track as the cart goes by. Now to make a few more and try it out. Once done I will make a video and make the files available to anyone who wants them. #iteachphysics #Physics

The potometer

 Using a potometer in the nice sunshine. The students can easily see the uptake of water and movement by transpiration. Important to set this up underwater. I am using watercress. It grows fast, has soft stems that easily fit into the tube and being water plants they transpire fast so the students can see the results quickly especially on a sunny day.

Galileo’s Acceleration Experiment

Galileo’s Acceleration Experiment - Going to build - I have 1 @pascoscientific ramp and smart cart several identical small bells and a 3-D printer to make some ball holders attached to the ramp. Now I could use the smart cart but this should be more fun #iteachphysics #Physics

Which Metal is the best Conductor?

 #Physics I have 4 metals, Steel, Brass, Aluminium and Copper. Putting them into hot water which one will heat up and conduct heat the fastest. #iteachphysics

Meter Stick Torque Kit

 @pascoscientific  meter Stick Torque kit arrived from @scichemed. Now to start some experiments with this. I found the kit to be really sensitive. Started using it straightaway with some rotational mechanics. #iteachphysics #Physics
