Curated OER
Carbon Dioxide
Students conduct a series of experiments to explore carbon dioxide properties. In this chemistry lesson, students explain the production and uses of this gas. They measure its amount in soda and waste product of yeast.
Curated OER
Limiting Reagent
Students work in small groups with a small set of 8 nuts and 5 bolts to assemble into combinations of 1 nut: 1 bolt, and 2 nuts: 1 bolt. They explore the outcome and discuss. Then a student mixes two clear, colorless solutions together...
Curated OER
Teaching the Scientific Method Using Adhesives
Middle schoolers research on the history of adhesives. In this science lesson, students select one test to use in finding the stickiness of adhesives. They collect data and formulate a conclusion.
Curated OER
Amylase
Students examine what amylase is and its history. In this digestive lesson students study the effect amylase has on starch and how temperature affects the rate of activity.
Curated OER
Lactose & Lactase
Students examine the characteristics of lactose and lactase. In this enzyme instructional activity students study the lactose in milk and its rate of dissolution.
Curated OER
Synthesizing Pigment and Dyeing Cloth
Students create a synthetic dye and oxidize the dye and record the effects.
Curated OER
Micro-Magic With Sticky Ions
Students view a video about the formation of precipitates. They complete a worksheet that asks them to identify what makes a compound form and what holds it together.
Curated OER
Teaching The Scientific Method Using Adhesives
Learners use the six step scientific method to experiment with the differences in adhesives. Students test for tack, shear, and peel in these activities.
