Les variables

Variable indépendante = variable manipulée/assignée

Axe X

Variable dépendante = variable observée /mesurée/ répondante

Axe Y

Variables contrôlées. Ces variables aident à rendre l’expérience juste et équitable

ex: Expérience avec fertilisant, utiliser le même type de sol ou la même sorte de plante pour que les conditions de départ soient toutes identiques.

Nous allons jouer à une version scientifique en utilisant les éléments du tableau périodique.  Mais avant de commencer, je t’invite à regarder les différents liens et visionnée la vidéo proposés afin de mieux de familiariser avec le tableau périodique des éléments.

Il s’agit d’une vidéo au sujet du  tableau périodique et ses éléments dans notre vie de tous les jours, composée et interprétée par le groupe They Might Be Giants.La chanson est malheureusement en anglais…

But du jeu

Former le plus grand nombre de mots en utilisant les éléments du tableau périodique.  Tout mot, nom, verbe, adjectif, adverbe, etc) ses dérivés, son pluriel, son féminin.  De plus, il est possible de former des mots en anglais également.

The Life cycle of a plastic bottle


https://www.montgomeryschoolsmd.org/uploadedFiles/curriculum/outdoored/programs/waterbottlefactpages.pdf

To help you see just how much waste your plastic water bottle is responsible for, let’s go through the stages that bottle’s life cycle.

MANUFACTURING

  1. First, crude oil and natural gas are pulled from the earth through large-scale extraction operations.
  2. Shipment #1: From here, the crude oil is shipped to a refinery. Make note of how many rounds of shipping are involved in the production of your water bottle. Each of these stages requires vehicles to burn fuel and release greenhouse gasses, creating a lot of waste.
  3. The refinery then distills the oil into its component parts, i.e. gas, fuel oil, etc.
  4. Shipment #2: Then the refined oil is shipped to a plastics factory.
  5. At the plastics factory, the oil chemically bonds with gas molecules to create monomers. These monomers undergo chemical processes which then bond them together into polyethylene terephthalate (PET), the polymer most plastic water bottles are made from.
  6. The PET mixture at this point is in the form of many tiny pellets. The manufacturing plant melts them down and injects the mixture into molds. The plastic takes the familiar shape of a bottle.
  7. Shipment #3: Next, the empty plastic bottles are shipped to the bottling plant.
  8. The bottling plant fills the water bottles with water. The bottles are then packaged.

DISTRIBUTION

  1. Shipment #4: The water bottles are then shipped to the grocery store, where they’re stocked and placed on shelves.
  2. Shipment #5: You buy the water bottles and drive them from the store to your home.
  3. You drink the water and toss the empty bottle into the trash or recycling.

DISPOSAL

  1. Shipment #6: The bottles are then picked up by waste management services. Approximately 73-90% of them go straight to landfills, where they’ll take about 500 years to decompose.
  2. The other 10-27% of bottles that are recycled are instead taken to recycling centers. The recycling center then sorts the bottles, melts them back down into pellets, and remakes them into other products. Those include things like carpeting, clothing, and other plastic items.
  3. Eventually, those products are also thrown in the trash, and that 10-27% of bottles that are recycled still end up in a landfill for the next 500 years.

How false news can spread by Noah Tavlin

In previous decades, most news with global reach came from several major newspapers and networks with the resources to gather information directly. The speed with which information spreads now, however, has created the ideal conditions for something called circular reporting. Noah Tavlin sheds light on this phenomenon.

https://youtu.be/cSKGa_7XJkg

Can you answer these questions?

1. What makes circular reporting ‘circular’?
2.Which of the following has NOT directly contributed to an increase of circular reporting?
3.Why might the anti-vaccer movement be considered a product of circular reporting?
4.Before the 20th century, because it took longer to publish writing, it was more accurate.
5.Which of the following is NOT an example of circular reporting?
6.What are some ways you can avoid falling for false information, and avoid contributing to the cycle of circular reporting?
7.What makes circularly reported facts so difficult to correct?
8.Circular reporting isn’t limited to large-scale media and news. How does circular reporting apply to rumors and gossip?

Write on

Does everyone who publishes any writing—even if it’s on their personal blog—have a responsibility to cite their sources and be factually accurate? Or does this responsibility only apply to professional writers published by well-known publications and websites? Why or why not?
