I have a habit of buying H2O2, putting it in the fridge, and forgetting about it until it’s no longer anywhere near 30% 😂 While this may not have had the “wow” factor I was hoping for, the conversations and suggestions between my 3 mini scientists were a great reminder that science doesn’t need to be perfect to be exciting!

The audacity, right? It’s the little things that will determine if you thrive in chem.

The Periodic Table is one of the most useful tools in science. Bring it everywhere, and don’t fall in the habit of relying on the calculator app in your phone either. Use the calculator you’ll be using on test days, so you know exactly where to find the exponent button. You have plenty of large numbers with exponents in your future! 😅

I may not be trendy, but trust me, you don’t want to make these mistakes when predicting and justifying Periodic trends!

Looking for a more in-depth look at specific trends? Check out my Unit 1 highlights for additional tutorials explaining these tricky patterns.

New tutorial on electron affinity will be posted next Tuesday. Until then, drop any questions you have in the comments.

I promise, it does get easier. Keep reviewing, keep crushing those practice problems, and check out my website for tons of free review content! New tutorial on Periodic trends will be live tomorrow. ⚛️

Thank you for ADULTS & KIDS STEAM CLOTHING for my favorite Ms. Frizzle dress! 💜

Have you seen the chemical chameleon reaction? I love this redox reaction for its wow factor, and the nice thing is, your solutions don’t have to be precise to get a cool color change.

Want to replicate this reaction? You’ll need KMnO4, NaOH, and sucrose (the mystery white substance now covering my bench). Let me know if you’d like a full explanation video! 🤓

If you can remember the rhyme, you will be fine:

Percent to mass,
Mass to mole,
Divide by small,
Multiply ‘til whole!

You may not need to use all of these steps every time, but remembering this will help you stay on track.

Let me know if you have any questions and what you’d like to see in the next tutorial!

Do I recommend memorizing the most common polyatomic ions? Yes! I know this is somewhat controversial in the land of AP Chem, but let me explain why…

There aren’t too many things you’ll have to strictly memorize in this course. Knowing the ions you’ll see most often (hydroxide, nitrate, acetate, sulfate, phosphate, carbonate, and chlorate) will make your life easier throughout the course! You’ll be able to interpret lengthy FRQs, use the polyatomic ions to confirm charges of transition metal ions, and easily predict solubility. These polyatomics are important for acid-base chem too, which is typically the most difficult unit for students!

Check out my website for flashcards to help you review some of these topics. New tutorial covering empirical and molecular formulas will be posted tomorrow!

It doesn’t matter how many times I see this or the iodine clock reaction… I’m always shocked!

Every Friday, I’ll share a fun demo like this chemical traffic light. Why? Because chemistry is cool. 😎

If you’re taking AP Chem, there’s a good chance your initial test will cover most of the material from Honors Chem. And yes, it’s likely that it will happen within a week of starting class! 😵

Hoping to prep for the wild ride that is AP Chem? Check out my “Welcome to AP Chem” playlist on YouTube for tips to get you through.
