Trojans Rookie camp week 2 Write up

Excellent rookie camp today, despite the weather we started with the usual warm up then footwork drills. This was using just the step overs was changed part the way through to help with different foot work drills.

We then moved on to some route tree drills, so going through different stances, then running routes such as drag, this was followed by tackling.

This week we were wearing helmets, rookie camp 3 we will be wearing both helmets and pads, so there is a clear and strong week to week progression.

Rookie camp 3

  • Date: Sunday 24th September 2023.
  • Time: 10:00 to 13:00
  • Location: Foxhole Community Centre Field, Bellfield Road, Paignton
  • Info : See website and social media

Percentage Composition in Chemistry 2

I have remade the video where I explain how to calculate percentage composition. Here I am using Methane as a worked example.

Hopefully it gets the idea across, I will make more and give different examples, hopefully in doing so I will learn and gain confidence in making these videos.

More videos

I have put more videos on the STEM Group blog

Code Club 16/9/2023 Write up

We had a rather busy code club today, a really good turn out and we had a good mix of Python, Scratch and Hour of Code activities. I tried to help people that needed help.

We also had a look at some of the donated laptops and gave one of those out, we were also downloading some drivers for windows 7 so one of the attendees could install on the laptop I gave away a while back. Hopefully people can get their laptop working from that.

Had a quick explanation as to what the Raspberry Pi is.

Hopefully by the next session on 7th October, the library can recruit some more help as I certainly need support with regard to coding or at least using Python etc. I can only go so far with the text based coding stuff before I get really stuck.

I will find some copies of the posters, as I didn't get a chance to get contact details of one of the parents so I can send a link to them. I kinda got distracted with helping other people.

It would be useful to get more code clubs in Torbay and ideally be able to collaborate with them too.

Next session Saturday 7th October.

LibrePlanet 2024

The call for sessions for the 2024 Libreplanet conference has been announced. This theme is cultivating community.

Details

he theme for LibrePlanet 2024 is "Cultivating Community." The focus will be on further growing the free software movement, mobilizing from the grassroots, and building a stronger community in the process. We will ask ourselves: How can we be a welcoming community that attracts newcomers as well as a lasting home to all those wonderful people who belong to it? As always, we welcome any talk related to free software and fitting one of the following tracks: Licensing, security, community, social context, hardware, freedom ladder, free software documentation, free software in government, education, or practice, workshops, or talks that explore the free software concept. Following our theme, we will highlight speakers who show ways of effectively organizing community, increasing diversity, facilitating the participation of volunteers, and encouraging users to contribute to their favorite projects. During the conference, you can learn about free software projects that invite newcomers to participate, community platforms that enable participation, and free software that attracts new users.

Session submission schedule

2023-09-06 	Call for Sessions opens
2023-10-25 	Call for Sessions closes

Details on how to submit can be found here

Home Chemistry 19 part 1

How to calculate what is needed for a displacement reaction to take place.

I asked this on Science forums but this is the basis of my question

I have some Copper Sulfate in solution, along with various metallic elements which should produce a displacement reaction for example

Rough equations@-

  • CuSO_4 + Mg => MgSO4 + Cu
  • CuSO_4 + Zn => ZnSO4 + Cu
  • CuSO_4 + Al => AlSO4 + Cu

If I make up a 0.1 molar solution of Copper Sulfate at 100ml volume I need 2.49g of Copper Sulfate in 100ml water. This is fine.

Now if I wanted to add just enough of one of the above metals to displace all the copper do I calculate as follows

( I could look this up, but I have an idea of how to do this, so am asking to see if I am on the right track)

  • 1 M of Copper sulfate weighs 249g
  • Mass of copper is 63.54 g then calculating the % composition gives
    • 63.54 / 249 = 0.26 x 100 = 26%

So if I have a 0.1 M solution, and used 2.49 g of the copper sulfate do I then work out what 26% of that is with

  • 0.26 x 2.49 = 0.65g

Therefore I need 0.65g of one of the above elements to displace the Copper

I think that I am nearly there with this, but given Magnesium , Aluminium and Zinc all have different weights, do I need to factor in the atomic mass of the element I am using for the displacement ?

Or just weigh out say 0.65g of Magnesium to produce

CuSO4 5H2O (solution) + Mg = MgSO4 (solution) + Cu + H20

I am not quite sure what happens to the 5H_2O here.

Am I right on my thinking here ?

WSJ Article on Exxon

I am sharing this as it really does expose what is going on at the top of the oil / gas / fossil fuel industries. This was posted to the Fediverse earlier.

Worth reading and sharing further, also we need to be discussing this and formulating a real solution to fight back against big oil and the fossil fuel industry.

Repl.it desktop app error

I have downloaded the Repl.it app for GNU/Linux Amd64.
1. Switched to a root shell with su - 2. Navigated to where the .deb file was downloaded to 3. Entered the following

dpkg -i ./replit_1.0.0_amd64.deb
  1. And got the following output dpkg-deb: error: archive './replit_1.0.0_amd64.deb' uses unknown compression for member 'control.tar.zst', giving up dpkg: error processing archive ./replit_1.0.0_amd64.deb (--install): dpkg-deb --control subprocess returned error exit status 2 Errors were encountered while processing: ./replit_1.0.0_amd64.deb

Issue seems to be the compression is using tar.zst, I have no idea what this is either, normally it is .tar.gz

Sharing here in case anyone else has a problem.

Update

Asked on the Replit forum and it seems it may have something to do with my Debian version, see post here

Code Club 16/9/2023

The next Paignton Library code club is on Saturday 16th September 2023, 10 am to 12:00. We will carry on with with the Code Club and hour of code projects and hopefully also the Python Projects.

We may have a potential volunteer dropping in to see what we are about too.

I have added more links below to try and reflect our current set of activities.

STEM GROUP – October 2023

The October event, scheduled for the 14th October has been Cancelled. This will allow me some time to stock take resources, and prepare properly for future sessions. It will also allow the library time to reach out and get some more help in to run sessions.

I was asked about the Horrible science kit (see below). This kit has about ½ of what is needed, the other ½ needs to be sourced. I need too work out what is practical to do during a session and also source these items accordingly. I can't get or buy everything.
