Virtual Code Club August 2020

The Paignton Library virtual code club is still running, please feel free to share what you are working on in Scratch with our Scratch studio

This is a newly created studio for these completed projects.

To keep people safe this studio is also invite only you will therefore need to contact the library, provide your scratch user name and I can invite you in.

Please contact [Paignton Library and information centre](https://www.torbaylibraries.org.uk/web/arena/paigntonlibrary

Related profiles :-

• Scratch: zleap
• Repl.it: @zleap
• FreeCodeCamp

Both Repl.it and FreeCodeCamp have excellent features, to share code, ask for help and help others.

I have been looking in to the Repl.it teams feature at the moment, early days as I think I will wait till the forum feature is up as this seems integral to the teams feature.

Stay safe on the forums.

For advice on e-safety please see ThinkUKnow

Organic Chemistry 4 : Plastics

Previous post

Moving on lets have a look at:-

• Polytetrafluoroethylene. See note at the end of the article.

I have built this using Molymods in the video below, Just imagine that the rest of the white atoms (hydrogen from previous video) are in fact green, Chlorine atoms.

You may find Molview helpful for visualising molecules on your computer screen too. This could complement physical building which I find can help understanding further.

I will post a few more videos showing the other molecules in that section of the infographic.

**Note: ** Polytetrafluoroethylene. It appears that Polytetrafluroethylene and Polytetrafluroethene are the same molecule, with different spellings depending on if you're using US or GB English.

Organic Chemistry 3 Plastics

Following on from organic-chemistry-2 we have had a look at Alcohols. So will now turn some attention to plastics.

So again we can construct models of plastics in a similar way, the main difference here is that plastics are POLYMERS, which are MONOMERS chained together.

Mono – Single Poly – Multiple

So looking at the above you will notice that they are using n to indicate there is more than 1 in the chain.

So starting with ${C2H2}$ or Ethene, this becomes Polyethene when more monomers are added to the chain.

So in the video below, I construct Ethene and then, in the spirit of Blue Peter, I am then using a few more I made earlier.

You may find Molview helpful for visualising molecules on your computer screen too. This could complement physical building which I find can help understanding further.

I will post a few more videos showing the other molecules in that section of the infographic.

Organic-chemistry-2

So following on from organic-chemistry-1. Lets have a quick look at another group: Alcohols.

• Nomenclature of Alcohols

SO following the same naming convention as Alkanes, we name Alcohols in a similar way.

• Methanol ${CH3OH}$
• Ethanal ${C2}{H5}{OH}$
• Butanol ${C3H7}{OH}$
• Propaol ${C4H9}{OH}$
• Pentanol ${C5H11}{OH}$

So in the video below. I have taken Methane and Pentane and made Methanol and Pentanol respectively from these.

As an extension to this, we can of course also construct 3-Pentanol where the Functional alcohol group is on the 3rd carbon along the chain. See video below.

You may find Molview helpful for visualising molecules on your computer screen too. This could complement physical building which I find can help understanding further.

Hopefully this is helpful. Have fun.

Organic Chemistry 1 (Basic Alkanes)

So following on from molecular-modelling-with-clay-part-1

I am going to stick to using the actual molymod kits. However, feel free to use clay if you don't have access.

So I have built

• Methane ${CH4}$
• Ethane ${C2}{H6}$
• Butane ${C3H8}$
• Propane ${C4H10}$
• Pentane ${C5H12}$

I have presented how these look in the video below.

So this shows you what these molecules look like using spacefill.

And below is a basic construction guide.

The following infographic may be useful here.

Further help and questions

If you would like any further help with chemistry (or any other science subject) then I have found ScienceForums to be a very useful, friendly and educational forum.

Free signup and there is a section there on homework help. As long as you follow the forum guidelines then someone should be able to help, don't forget to upvote any answers.

Feel free to tag me in to posts @paulsutton, I am sure there are others who may be more able to help with specific questions on science generally.

Chances

Jonaed Iqbal

Jonaed Iqbal The Harvard debate team went against a prison debate team. Who do you think won?

The Prison debate team!

Isn't that crazy?

Not only did they beat Harvard, they also beat the University of Vermont, West point and the University of Cambridge.

These are prepared debates where both sides are given a position that they have to defend.

The university students have access to the internet.

The prisoners only have access to books in their prison's library.

Some of them don't even have their GED.

They are competing with students that typically grew up in wealthy households. Some of the people they are competing with have started debating at 4 years old.

It just goes to show that you really shouldn't count anyone out because of their background and their lack of formal education.

It's a beautiful site watching debaters in state issued green jump suits wearing bow ties borrowed from their fellow inmates beat opponents dressed in black suits.

More molecular modelling

So following on from my Post on 23/7/2020 I decided to share some of the info graphics created by Compound Chemistry

These are useful for GCSE and A'level chemistry. Building the models could help enforce the learning provided. I would strongly suggest talking to your teacher for advice on this.

So first off, looking at how different organic molecules are named.

So you should be able to take some of the diagrams here and create some basic models. Don't forget to you can use the bendy straws for double bonds.

As isomerism is also covered in the curriculum (or was) this may also be useful.

There are lots of infographics on the website listed below.

• Compound Chemistry Twitter
• Discussion forum on Qoto Discourse

Online and remote learning : Lets not forget privacy.

This is an excellent article by the Free software foundation on the importance of maintaing user / learner privacy while they are learning online.

Some interesting points being raised and some serious concerns about privacy, use of webcams and monitoring of students during tests etc.

Learners need to ask questions and not just accept this as the new normal.

Scratch Project 7

In an effort to help people keep kids occupied over the CoronaVirus (Covid-19) crisis. I am helping my local library with running a virtual code club. We are now on week to of the virtual code club.

Please contact Paignton Library for more information. Please use social media or e-mail as the library is closed.

Scratch Project 6

So further to my previous post I have completed another two module1 activity.

Firstly Boatrace

Secondly, Chatbot, well sort of, what I have done is to add a introscreen so this displays first.

I have created a new studio for these completed projects.

To take part please follow @paigntonlibrary on twitter
