SI Base Units and Powers of Ten Card Sort
This activity is designed to help students identify, recognize, and convert within the most common SI units and powers of ten. Students are given a set of 40 cards to be sorted into ten groups of four cards each. Depending on the number of students, they may work in pairs, small groups, or individually. Each group of four cards must have the same quantity – for example, mass, length, or volume. The cards are to be arranged in ascending order, from smallest quantity to greatest. This activity c

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
