Support ChemTalk's Mission

For All Students

We have hundreds of lessons designed for middle school, high school and college chemistry, organic chemistry ,and biochemistry. We also have additional resources for students to learn more about elements, experiments, lab techniques
,and much more.

Diverse Resources

We have resources on multiple platforms including Youtube, TikTok, Instagram and Spotify. All of our ChemTalk podcasts are on multiple podcast streaming platforms for easy access for everybody.

Free Materials

All of the materials that we offer are free,ad-free, and barrier-free. We strive to provide useful resources to all chemistry students and teachers to make chemistry fun and easy to learn.
