Bonding

Activity 1 - Metallic hydrogen?

Subtopic 4.4 - Metallic bonding

NOS statement 1.4 - Creativity and imagination

Time: 5 min.

Task: Hydrogen exists as simple covalent molecules. What would need to be done to make hydrogen gas exhibit metallic bonding?

Possible answer: Scientists are investigating a creative yet very simple way of doing so LINK

NOS statement 1.7 - Scientists must adopt a skeptical attitude to claims.

Extension: How would you prove that "metallic hydrogen" has been made? The scientific community is currently scrutinising the results

Activity 2 - The most simple Nobel Prize yet?

Subtopic 4.3 - Covalent structures

NOS statement 5.6 - Many scientific discoveries have come from speculation or simple curiosity about particular phenomena.

Time: 5 min.

Task: Look at the image below. Can you guess what the story of this Nobel prize winning discovery?

Activity 3 - The 1987 Montreal Protocol

Subtopic 14.1 - Further aspects of covalent bonding

NOS statement 4.3 - Examples of large scale collaboration

Time: 10 min

Task: Watch the video to the right and make a list of possible consequences had the Montreal Protocol not been passed.

Activity 4 - What really causes bonding?

Topic 4 - Chemical bonding and structure

NOS statement 1.1 - The underlying assumption of science is that the universe has an independent, external reality accessible to human senses and amenable to human reason.

Time: 5 min.

Task: Take any type of bonding and begin to ask why it happens. Continue to ask why? until you can go no further.
