There are 3 places students get stuck in VSEPR:

• They never learn electron domain
• They get confused on how many electrons to put in the model
• They confuse electron and molecular geometry

If you'd like to know how to fix or prevent those, then listen to the episodes.

This week on the podcast we have a mother daughter duo. Angela and Ashley teach us:

Why as science teachers we should be open to changing our curriculum order
How chocolate soap will teach lab rules for us
What we should do to interest our students in chemical careers
How  PowerPoint will effortlessly translate your lectures
Why they start their chemistry course with thermochemistry

...and so much more.

Are you looking for a fun way you can teach quantum numbers? One that requires nearly no prep on your part? This is it. We have students relate quantum numbers to a coffee mug.

Start by having students take out a sheet of paper and labeling n, l, ml, and ms along the left side. Then you'll use a coffee mug as a tangible analogy to describe the orbital the electron is in.

The best part of this lesson is when you walk around and tell students what their mug looks like and where it is. Don't forget to take a little creative license with this! ("Does your mother know you left your dirty cup in the sink for her?!")

It's interactive, engaging, and entertaining. Quantum numbers doesn't get more memorable than this.

Why do chemistry students forget significant figures? Because they are so confusing to apply. But, not if you explain it using the word "specific" and break them down into 4 simple types of significant figures.

Sandwiched zeros (Not hostage or captive zeros. Why? Listen to the episode. )

•      These are specifically measured. Not ballparked or guestimated.

Trailing zeros with a decimal

•     These are specifically measured. Not ballparked or guestimated.

Trailing zeros without a decimal

•     These are estimated. An educated guess. So we can't know what the exact number was.

Leading zeros

•     These could have been measured or guestimated. No one knows because they are placeholder zeros. So we assume they are not specific and are not significant.

Why do students mix up cations and anions? It turns out that if you start super simple, it will make more sense to students. Students need to learn cations are positive. And that anions are negative. Theeeeennnnn, jump into why cations are cations and why anions are anions.

Giving students the why too soon will confuse them.

Here's the blank periodic table and cation worksheet I referenced in the podcast.

You can see all the cation and anion images I was referencing in this blog link.

Have you ever wondered if there is another or better way to teach chemistry? Does everyone start school in August?

Stacy explains how science is structured in Australia and in Scotland. For example, there are 2 week breaks every 10 weeks in Australia, which Stacy explains helps with burnout. Australia also starts school in January.

Scotland also gets more breaks than the United States.

Stacy talks about the differences in teaching chemistry between the two countries. In Scotland, they start off talking more about the atom and periodic table.

Do you need a memorable way for students to learn how to find protons, neutrons, and electrons? So many students get stuck on not knowing where the numbers are coming from. But after this lesson, your students will know where the numbers are coming from AND be able to calculate protons and neutrons.

The best part is that this appeals to all of your students and not just those who "get" math.

This episode will help you use color coding as a strategy to help students remember the subatomic particle lesson.
