Day 12: Soldering

Concluding our bonding cycle using soldering as a way to learn more about the application of alloy chemistry.

Day 11: Quiz Prep

Typical quiz prep day. Displayed various images of particle diagrams and students responded one of the following: Ionic, Polar Covalent, Non-Polar Covalent, Metallic (Interstitial or Substitutional Alloy), or Network Covalent. Students then buzzed in their answer using a form. See image
Since each team had a separate column of the form to enter their response, the associated spreadsheet told me who answered first in a visual way (better than tracking time stamp). See image. I'm sure there is some fancy application that could do this better, but in the end, hacking it up this way was more fun for me, and visual for the kids. IMO. .

Days 9,10: Ionic and Metallic Bonding

Using soldering and home-made conductivity meters to study alloy and ionic lattice structures.

Day 8: Unknown Identification

Qualitative analysis of bonding patterns. Starting with particle model overview on macro level to build greater property awareness.

Day 7: Octadecanol

Melting, freezing and modeling Octadecanol.

Day 6: Bonding Intro

Visual inquiry around particle diagrams bonding. Boring but important.

Day 5: Flame Tests

Relating Ionization Energy to emission spectrum. Led to discussion about what causes a "Green Flash".

Day 3: Coulomb's Law

Modeling Ionization Energy using cardboard and magnets!
