Blowing bubbles

What do  metals look like - blowing bubbles gives a good idea. Using sheets of molymod atoms joined together shows the sliding over. Layers of tracing paper also work well, put the tracing paper in the printer and print several identical sheets. #iteachchemistry
 

Looking at the demo eye lens

 The @pasco demo eye lens consists of a ring with two pieces of plastic either side. Water can be pumped into or out of the ring via the syringe, which cause the plastic to swell or contract forming a variable shaped lens.

Burning Magnesium

 A quick video  as a short  directly uploaded from the phone, no description and it gets 2.7K views in 2 hrs. Perhaps I am doing this all wrong.

Numbers of views increases at pace

 My YouTube channel achieved 6,000,000 views on April 27, 2022!

Photographing Crystals

 Needing to set up the cameras on the microscope to gain a good view of the crystals made. The virtual of a microscope  like this is the ability to place an SLR in position which is many times better than using a eyepiece camera.

Taking a close up of the eye

 Trying to get a good image of the iris contracting proved to be more difficult than we expected. We needed a camera that could get in close enough and this proved to be an Olympus TG-5 on macro mode.

Woolly Digestive System

The digestive system fits into a clear bag about life size so the students can see how it fits together and then they can take it out of the bag just to see how long it is. Knitted by my wife.

 

Setting up the camera

Looking at how the @Pasco adjustable focal length lens works -  using an overhead camera to get in on the action

Online organ lesson

 My Zoom organ lesson with Tom Horton. Needing three cameras, an atem and some mics. Now deciding whether to mix the sound as well.

Ordered

 Ordered - One Blackmagic Hyperdeck Shuttle HD. Might be here in a week!

Half a million views in 10 days

 April11 - April 19 we gained half a million views. So great that the channel is doing well and attracting new and keeping existing subscribers. The content goes on and on.

New Blackmagic tools for us

 

We have had various gripes about the hyperdeck and how we want to use it. The new HyperDeck Shuttle HD answers all our moans and gives us a free teleprompter as well. And the cloud pod shows us how online should be done. Now we are off to order one.

Lights and flags

We all use lights to illuminate the subject when filming, but flags are also useful, for blocking off light where you don't want it, getting rid of reflections which make it difficult for the students to see what you are doing clearly.
 

How does a gold leaf electroscope work

Another short. Continuing the series on electrostatics , I look at what is a gold leaf electroscope and how it works.
 

Filming electrostatics

With all the different social media platforms, we now have to film all our work in Portrait, Landscape and square, trying to capture all the detail in the centre of the frame or filming three times or filming with one format and editing the others out.

Monitoring

 How big a monitor Do you Need? The answer comes - it depends on what you are doing. When I am teaching the students I use a large 55 inch monitor, because I am interacting with the student. When we are livestreaming with less interaction then a smaller screen is needed.

Scripts

Streaming or recording you always need to work from a script so you know what to say or cover next. You don't need every word planned out, often bullet points will do.

Online and in person Revision

Whilst many teachers take a well earned break it is still all go here working on A level and GCSE revision both online and in person, trying to improve those grades ready for the exams.

The Bean Bag

 Using the camera on a bean bag to get stable shots when out and about and a tripod is just not possible.

​5 Million views

 ​5 Million views. The YouTube channels is still continuing to do well. More videos still to come

I.T. Support

 Visiting my Mum usually requires a lot of IT support. This time we failed. No broadband from the new sky box. Need an engineer.

The right position

 Trying to get the camera in the right position on this @Pasco demo eye so the students can see what I want and need them to see is sometimes a bit of a challenge.

BSC Expo

 Went to see @CVP at the @BSC_EXPO looking at the new NDI workstation on display at #bscexpo2022 Powered by NewTek Tricaster mini 4Kb #cvpbsc2022 Now I need one!

Flat LED Panels

Using just two flat led panels, one from each side and at different powers makes for great illumination. The bigger the panel the better the light, but if you are only doing head and shoulders then small is ok.

Practise

What do you do when you are on holiday? Do do practice and refine some experiments and demos so that the students can gain more benefit from them?

Ready for the editing

Having recorded the video and taken some stills for the thumbnails then all the files are saved in at least two places before we start to edit the files in our favourite editor DaVinci Resolve.

Essential kit the rode wireless Lav Mic

Probably the most important item in the kit for any video is the Rode Wireless Lav Mic. It means I can wander around the lab as I teach and the sound stays with me. The quality is great and crystal clear.

I can barely keep up

 The views and the subscribers keep rolling in and of course many more videos to make.

DJI Osmo Vertical viewpoint

 

Setting up the DJI Osmo to take vertical video of the experiment to give a clearer idea what is happening.

Youtube site continues to Grow

 The numbers are still increasing and the new videos are doing well especially the shorts. Its keeping the production line busy.
