microscope stage calibration slide

Using a microscope stage calibration slide to work out the measurements in the eyepiece graticule. Students seem to find it a hard concept to look at a ruler with an eyepiece graticule, then remove the slide, replace it with the subject, and be able to measure it.

 

Set up for molten electrolysis

 Setting up ready to do electrolysis of a molten substance. Most of these are too dangerous to do in the lab and require a fume cupboard to do safely.

New Camera Boat

 An all-electric Ocean Green Whaly 455 is undergoing trials on the River Thames, ready to be equipped as a Camera Boat. The boat is virtually silent, apart from the noise of the prop pushing the water.

Bluetooth

 Disaster struck. Some of my machines suddenly wouldn't connect the Bluetooth devices to @pascoscientific Capstone. The Sensors were fine, but the Bluetooth suddenly died on two machines. Windows pretended it was working. The new Bluetooth dongles are in, and they are working as before.

Conditional Probability

 Conditional Probability is one of the Math concepts that the students really find difficult, but translating the word of the question into the formula makes everything so much easier.

Lego Pneumatics

 Examining the power of pneumatics with Lego, pumping up a pressure tank and then using these to open or close a cylinder, the students were amazed at how science backs up engineering principles.

Flowers

Flowers exhibit a stunning variety of shapes and styles, each uniquely designed to attract insects for reproduction. Their relentless evolution highlights the beauty of nature's ingenuity, even as pollinators become scarcer. #Nature #Evolution #Biodiversity
