#SciStuChat – Surviving a year in space

Every month, there is a #SciStuChat Twitter chat for students all over North America to communicate with scientists on a different theme. In October, the theme is “Surviving a year in space” and the chat will be Thursday (October 8) from 9-10PM:

Astronaut Scott Kelly is spending a year in space on the International Space Station, and his Russian counterpart cosmonaut Mikhail Kornienko is doing the same thing. On Sept 15 they reached the halfway point of the#yearinspace. The major purpose of the #yearinspace is to learn the demands the human body requires to make the trip to Mars. 

You can find more information here. Since some of you have not participated in a Twitter chat before, I put a few tips together. This is an optional activity, but I recommend it. You will have the opportunity to ask real scientists questions!

Gases objectives

We are just starting the Gases unit. Here are the big picture questions that I would like you to keep in mind while we’re working through this unit:

  • Why are certain gases better suited for specific uses?
  • How can you handle gases safely?
  • What is the difference between a real gas and an ideal gas?

In addition, here is a summary of what you are responsible for in this unit:

# Objective Must-do Activities Videos
1 Associate the use of certain gases in various applications with their chemical reactivity Chemical Reactivity assignment Reactivity
2 Explain the behavior of a gas using kinetic theory KMT Worksheet KMT
