Wave speed

Determining the velocity of waves in a ripple tank using a phone to capture the wavelength and the videoing in slow-mo with a clock timer in the background to determine the number of waves passing a point per second.

 

Life Size Wooly Gut

Looking at the gut makes the students squeamish, but playing with the life-sized knitted woolly gut is fun, and they're amazed at the diameter and length of the small intestines.

 

Moments made easy

 Moments made easy using Balance Me from Phet. So many useful simulations for the students to learn with.

Old and the New

 Using the USB to 3 1/2 Floppy Disk. I haven't found a 5 1/4 equivalent yet, But I can use some very old PC's to still use them.

Potable Water

Making water safe to drink in the lab. Starting with River water and rainwater, we looked at how dirty they were. then put them through a water filter of gravel sand and activated charcoal. Clean but was it safe to drink - no. Next to see what bacteria is in tap, bottled distilled water and compare them to sea water, rainwater and river water.

 

Radioactivity

 Using the @Pascoscientific Wireless Geiger Counter with the sample holder and using different numbers of metal sheets to reduce the count.

Further Maths

 Playing with 3-D Vectors and comparing this to working with CAD. Rotating objects around, measuring distances to see real-life applications of the Maths.
