Updating the Wireless Sensors

 #Physics is spending some of the morning updating all the @pascoscientific wireless sensors to the latest firmware versions in Capstone and Sparkvue. Light Sound, Pressure, Temp, ultrasonic distance, conductivity and WiFi #iteachphysics

Boyles Law

 #iteachphysics Getting ready to do some of the gas laws. This is Boyles law. It relates pressure to volume. As the pressure increases the volume deceases #physics

Lever Arm Balance

 #Physics Weighing the calculator using an old fashioned but accurate Lever Arm Balance. When I was at school this was the best machine we had, nowadays the students seem to reject it but are still fascinated in how it works. #iteachphysics

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.
