How I Teach Natural Selection to 6th Graders (Without Losing Them)
Natural selection is one of the hardest concepts in 6th grade science, not because it's complicated, but because students arrive with deep misconceptions baked in. Here's the sequence I've built to address those misconceptions head-on, including a simulation that generates real data students can graph and interpret.
How I Teach "What Is Life?" to 6th Graders
The six characteristics of life look like an easy first unit, until students try to apply them to viruses, seeds, and fire. Here's the full sequence: from the hard cases that break the checklist, through Cell Theory and prokaryote vs. eukaryote, to the games that lock it all in.
Reading Rock Layers: Teaching Superposition Without the Textbook
The rock layer unit is a gift: it's visual, it's logical, and students can actually do the reasoning themselves if you set it up right. Here's how I structure the three-day sequence using relative dating and index fossils.
Making Body Systems Stick: An Interactions-First Approach
Most students can name body systems. Far fewer can explain how they work together. I've flipped the sequence (we start with interactions and work backward to individual systems) and it makes a real difference.
A Plain-Language Guide to Grade 6 MA STE Standards
The Massachusetts STE Frameworks document is 400 pages long. Here's what Grade 6 science teachers actually need to know, organized by unit and cross-referenced with NGSS Science and Engineering Practices.
Free Interactive Tools for Middle School Science (That I Actually Use)
A curated list of web-based tools that work on Chromebooks, don't require logins, and are genuinely worth the class time. These are the ones I return to every year.
