Seltzer Breath
Young scholars investigate "indicator" (Bromothymol Blue or BTB) to test for the presence of certain chemicals in liquids and gases. They compare distilled water and seltzer water for presence of carbon dioxide.
Curated OER
Egg Measurement
Pupils explore measurement and units. They measure eggs to determine their density, mass and percent composition. An inquiry approach is used for students to ascertain the mass.
