Open Learn – Discovering Chemistry

Anyone looking at undertaking this course with Open Learn, I have set up a thread on discourse to facilitate further discussion.

Chemistry lies at the centre of our modern life, playing a part in areas as diverse as the development of new drugs and materials, analysing our environment through to more mundane activities such as washing your clothes and making your tea. But to truly understand the role chemistry plays you need to have a sound grasp of a number of fundamental principles.

This free course, Discovering chemistry, introduces you to some of these concepts, beginning with the idea that everything that you can see is made of building blocks called atoms. This leads on to a look at the chemical elements and how they are arranged in the Periodic Table, enabling chemists to rationalise patterns in their chemical and physical behaviour.

Next you will consider chemical reactions, specifically how atoms combine with other atoms to form molecules, and how molecules combine with other atoms or molecules to form bigger molecules. You will meet simple (tried and tested) theories to explain the bonding in molecules and at how their shapes may be explained, and indeed predicted. And in a wider sense you’ll be looking at why reactions happen at all and how fast they go.

This is also a beginner’s level course in the language of the chemist; you’ll learn about symbols, formulas and how chemical equations which represent reactions are constructed. Finally you will see how chemists count atoms and molecules, essential for making up solutions of a known concentration in order to carry out a reaction, or performing a chemical analysis.

Reverse Image Search

Latest resource in the Data Detox kit from Tactical Tech is reverse image searching. This helps you identify the source of an image, which in turn helps you differentiate between accurate and misinformation.

These resources are well worth checking out. I am still planning on trying to do a talk on privacy at a future STEM group event.

Could be something to discuss at the STEM group meeting or via Discourse or on Mastodon.

Which role models are best for STEM?

Just found this posted to Mastodon by Science Daily bot. May make interesting reading.

STEM GROUP MEETING

The Paignton STEM Group's aim is to bring together people who are interested in Science, Technology, Engineering and Maths. Provide a safe space for discussion, showcasing of projects and to encourage and advocate STEM subjects.

The first Paignton Library Stem Group meeting is

Date : Saturday 13th November 2021 Times : 11am –> 1pm & 1pm to 3pm

Booking essential. Under 8's must be accompanied by a parent.

01803 714 460 for details / booking

In preparation for this, I have been working on creating some electronics resources to demonstrate at the event.

These are quite simple to make, solder on headers and which ever component is needed for that particular board

Electronics 1

Various resistors 270ohm 330ohm 1k ohm 10k ohm

Electronics 1

Power supply, we need to get power from a battery to the circuit.

Electronics 1

Reed switch (not soldered), 1uF capacitors (soldered) and a switch block, not soldered as I want to figure out which switch block to use (I have a few)

Electronics 1

Transistor NPN 2n222A

All soldered up so they can just be wired up.

I have added a 3 way header as this allows for:

  • Components to be attached together
  • Branches in circuits
  • Connection of meters, scopes and other equipment

It should be possible to build a circuit that, internally will flash, for example an LED then use a scope to examine the frequencies at different points in the circuit.

I plans to solder up other component boards. Hopefully I will have something to demonstrate, but other visitors should be able to have a go.

April Tech Jam Summary

At the South Devon Virtual tech jam, on Saturday, we had discussions on quite a wide range of topics., these included:

Computer hardware such as Chromebooks and PC's not offering a choice of Operating System (OS) and the ease of which we can install what we want (e.g. a GNU/Linux) based system on shop bou ght hardware. This can be challenging with the use of non-free firmware, for example wifi firmware. The resultant collective opinion was that it would be nice to be able to go to a shop and just buy hardware with Linux pre-installed, or not have an OS at all giving us the option to install our own OS. While we are able to do this, the barriers are higher for the average user who is non technical.

We also discussed cloud computing, one drive and what happens if you lose access to your data, MS office now being a subscription model. We then looked at Nextcloud and the technical barriers for people to set that up securely. Eventually this moved on to a discussion on running software such as zoom as snaps (container packages), as I currently run Nextcloud in a Docker instance.

A discussion on using LaTeX, the advantages and if it is better to use Overleaf, a local install or have both available. This was also related to a discussion on distance learning and studying at University level generally.

After a short break the topic turned to what happens, when there is a disaster, causing lines of communication to be damaged, so no phones, mobile signals, electrical systems damaged. One suggestion was Morse code, so we discussed that, which led on to a discussion about hardware running forth, which then led in to a discussion on moon bases and certainly long term space missions needing computer hardware which will need to last 100's of years. This could be a long, multiple generation, journey to a star system for example Proxima Centauri. It could take 100's of years to go just 4+ light years in distance, given how fast current space craft can travel.

So in all, a very varied set of topics, Really interesting.

Next jam is 8th May where there will be more of the same. See Meetup. If you sign up and follow we will send you a notification closer to the time.

New Chemistry podcast

I found a link to this on Twitter so am sharing here too. A new Chemistry podcast from the European Young Chemists' Network has started. The first episode covers “CO2 Reduction, a Possible Solution for the Climate Crisis?”

Malaria Treatment

Even though we are in a global Covid 19 pandemic, it does not mean other important discoveries are not being made.

The BBC reported on May 4th that a microbe has been found that can block Malaria [1]. This is an important discovery, as the Center for Disease Control and Prevention (CDC) article [2] suggests that Malaria killed 405,000 people i 2018.

Discoveries such as this, surely give the world hope that a treatment for Covid-19 will eventually be found. It also highlights the importance of research and proper funding for research.
