Quiz on Chapters 7-8 of Lois Lowry's The Giver
This is a brief, 7-question quiz on Chapters 7-8 of Lois Lowry’s The Giver. It is meant as a quick check of comprehension shortly after the chapters have been read, so it asks only fact-based questions about plot, character, and setting. No analysis or interpretation is expected. Taking and reviewing the quiz at the beginning of class serves as an excellent transition point into a deeper discussion of the chapters. Of the seven questions on the quiz, THREE are open-ended and can be answered wel

Forensic Entomology Case Files PMI Lab (ADD Calculations) Print & Go 9-12
This is the forensic unit students always remember—because the “evidence” is alive (and the math actually matters). In Forensic Entomology Case Files, students work as forensic entomologists using insect development and Accumulated Degree Days (ADD) to estimate postmortem interval (PMI) and test suspect alibis. Every case is built around authentic reasoning: temperature → metabolism → development stage → timeline. This pack is print-and-go (no materials, no prep) and perfect for Forensic

Osmosis & Membrane Permeability Lab Water Potential (AP Bio) Dialysis + Key
If you’ve ever taught osmosis and still had students guessing “hyper/hypo,” this is the lab that fixes it. ✅Osmosis & Membrane Permeability is a 2–3 day Biology/AP Biology investigation where students move from observable evidence (color change + mass change) to AP-style water potential math (Ψ = Ψs + Ψp). Students model selective permeability with dialysis tubing, quantify osmosis using % mass change, determine the isotonic point of potato cells, and use water potential calculations to predict

Ohm’s Law & Circuits Lab (V=IR) Series Parallel KVL KCL Power LED + Key
This is the electric circuits lab that actually teaches students how to measure like physicists—not just plug numbers into formulas. In Ohm’s Law and Simple Circuits, students learn to use a multimeter correctly, verify V = IR with a clean V vs. I graph (slope = resistance), then build and analyze series, parallel, and mixed circuits using Kirchhoff’s Voltage Law (KVL) and Kirchhoff’s Current Law (KCL).It’s perfect for Physics / AP Physics 1 and comes with strong teacher support, expected result

This is the Newton’s 2nd Law lab that actually produces clean, meaningful graphs and teaches students how experimental physics works (controls, linearization, and real error sources). Students verify F = ma by independently varying net force and total mass using an Atwood-style cart-and-pulley system—then graph relationships, interpret slopes, calculate % error, and extend the lab with a friction correction.Unlike “plug-and-chug” worksheets, this investigation trains the exact skills that show u
