Real Science Teaching. Real Classroom Experience.

I’m Amy Brown, a veteran high school biology and chemistry teacher, wife, and mom who understands the daily reality of lesson planning, grading, meetings, and everything in between. I know what it feels like to have too much to do and not enough time to do it.

After decades in the classroom, I’ve created rigorous, classroom-tested biology and chemistry resources that save you planning time while still delivering strong, meaningful science instruction. Every lab, activity, and lesson is designed to move students beyond memorization and into real scientific thinking.

If you want your students excited about science and thinking deeply without spending your entire weekend planning, you’re in the right place.

Biology Review Activities Students Love: Hidden Picture Games

Biology hidden picture review activities in Google Sheets

If you are looking for a biology review activity that is more engaging than a traditional worksheet, these Google Sheets hidden picture games are a fun and effective option for high school biology students. This digital biology review format gives students instant feedback while keeping them actively involved in the review process.

These self-grading review activities are interactive and easy to assign. As students answer questions correctly, part of a hidden picture is revealed. That built in feedback keeps students motivated and helps them immediately recognize when they need to try again.
