CHemistry continuing from flame tests

After looking at flame tests in Chemistry seeing where the different colours come from using discharge tubes and a @pascoscientific spectrometer to ensure all the students see the same thing.

 

Weather Sensor

 We seem to be having a lot of weather events at the moment, so it is worth recording some of these events using the @pascoscientific wireless weather sensor for later use in the classroom.

Maths Draw a Diagram

 Some online Maths Tuition. Drawing a diagram to show what is happening is even more important. Colour coding helps identify which part we are talking about

Refraction

 A simple but still cool trick with a glass of water and an arrow behind, watching the arrow switch directions because of refraction.

Coloured Mould

 Some interesting Red Coloured mould on an old piece of cheese was found in the fridge. It will make an interesting study under the microscope.

Mesh Networks

 Investigating Mesh Networks. How do they work? Where to position them for the best WiFi. Selecting the best channels for WiFi reception. Setting up effective routing to access all the devices on a network regardless of the OS. Some fun playing with Wireless Networks.

Alkali Metals

Watching how fast Sodium oxidises in the air before comparing its reactivity to Lithium and Potassium in water. A really great, fun experiment.
