The Blue Bottle: An Example of Teacher-Guided Inquiry
Students observe a demonstration in which a bottle containing a colorless solution is mixed, turns blue, then becomes colorless again. They record observations, form and discuss hypotheses, and draw a conclusion based on the evidence.
Curated OER
Inside an Atom
In this atom worksheet, students read about the history of the discovery of the atom. Students write a story, poem, song or other creative project in which they shrink to an incredibly small size and are trapped in a carbon atom.
Curated OER
Estimation and Significant Figures
Students investigate the importance of significant figures through measuring and estimating. In this estimation and significant figures lesson plan, students measure pieces of paper and round their figures to the nearest marking on the...
