Concentration

 #chemistry Looking at concentration. Copper Sulfate works well giving a visible indication of the concentration and so does orange squash ( and the students can drink that to check the concentration). #chemtwitter #STEMeducation

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
