Paignton Library Summer Virtual Code Club 2

To continue with the Paignton Library Virtual Code Club.

Paignton Library will be sending these activities out via Social media using the hashtag #PLAIC_codeclub

• Paignton Library Facebook

• Paignton Library Twitter

• Download poster (pdf)

If you don't already have an account for either home or school then you can sign up to a free scratch account via * Scratch

While all the Scratch Module 1 activities are here

• Scratch Module 2
• Scratch Module 3
• Scratch Additional

The modules can either be followed as they are, or as with the physical code club, are useful as a guide. If you get stuck or need inspiration how to do things.

We still have the Library Studio up here.

• Scratch Studio

If you share with the Scratch studio, remember to do so safely and not share too much personal information. By sharing you can help others, learn from others and improve your own learning as you go.

I created some of my own instructions, for Scratch 3.0 a while back which are presented below.

• Timer
• Text2Speech
• Movement
• Collision
• Balloon Pop

updated the above list to point to GitLab rather than GitHub as I am moving away from GitHub as much as possible

Organic Chemistry 6: Benzene Derivatives in Organic-Chemistry

So as an extension to yesterdays post Compound chemistry have an infographic on Benzine derivatives.

So once you have made a Benzine molecule, this can be easily modified to some of what is presented here.

Organic Chemistry: 5 Phenyl Group

As Polystyrene Contains a C6H5 Phenyl group. Before moving on to building this, we can look at similar molecules that also contain this group.

• Benzine C6H6
• Phenol C6H5OH
• Touline C6H5CH3
• Aniline C6H5NH3
• Chlorobenzene C6H5Cl
• Benzenethiolate C6H5S-
• Styrene C8H8 Monomer of PolyStyrene

Video should show making of the above compounds with Molymod components.

Tomorrow, I will post a follow up on more benzene based molecules to build. So please keep hold of the C6H6 Benzine model.

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.

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.

#chemistry,#organic,#compoundchemistry,#modeling,#molymod, #education,#plastics,#Polytetrafluoroethylene,#Polytetrafluroethene #monomer,#polymer

**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.

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.

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.

Physics news 4th August 2020

I asked about this on Twitter earlier. More to ask if I was right in thinking a dimuon was two muons together.

The full article can be found below.

• CERN experiments announce first indications of a rare Higgs boson process.
  

Lots of interesting things happening at FermiLab then.

“US CMS is very proud to acknowledge the significant impact made by its members in deploying innovative analysis techniques, including cutting-edge AI methods, which were critical in establishing the evidence for Higgs boson decays into a muon and antimuon pair,” 

It may be an idea to have an understanding, or a copy of the standard model of particle physics to hand.

This is also being discussed on the qoto discourse instance. Where there is also an updated standard model graphic.

You may also find Science Forums a good place to discuss.

This has also prompted me to try and figure out how to typeset the basic equation in LaTeX.

\$$H\longrightarrow \mu^{–} + \overline{\mu^{+}} $

So to quote the $\textit{news.fnal.gov}$ website

• Please ignore the $'s at either side of the equation, these will be removed at some point.
