Activity #17 Co2 From Alka Seltzer
Students observe what occurs when Alka Seltzer tablets are added to water. They explain why water stays in the jar when it is above the surface of the water. Pupils test for the presence of carbon dioxide by conduting the match test.
Curated OER
Liquids Have Differnt Viscosities
Pupils explore visosity of matter. They run tests of various liquid substances to observe and compare rates of flow of different substances. In addition, they relate viscosity to distance travelled by sample substances.
Curated OER
Exothermic and Endothermic Changes
Students define and identify endothermic/exothermic reactions. Using a series of experiments, they construct and interpret potential energy diagrams for their reactions.
Curated OER
Acid-Base Indicator Paper
Learners are able to prepare and use pH indicators in paper form. They find out the color of the indicator paper plus test solution may change with time. Students use red cabbage to use for the indicator.
Curated OER
How to identify a physical change from a chemical change
Pupils identify the difference between some physical and chemical properties and compare some physical and chemical changes. They design an experiment to distinguish between a physical or a chemical property of their choice.
Curated OER
Activity #5 Environmental Effects
Students explain the implications of particle theory of The Law of Conservation of Matter for problems of pollution and waste disposal. They describe, in terms of atoms and molecules, what happens to materials when they are dissolved or...

Teaching about Aquatic Respiration
Young scholars explore respiration in a lake ecosystem by experiment and research.
Curated OER
Cool Activities: Make Slime
Learners analyze chemistry by conducting an in-class experiment. In this slime lesson, students discuss what slime is and what form of matter it qualifies as. Learners utilize borax, glue, water, cups, food coloring and plastic bags to...
Curated OER
Diaper Challenge
Students investigate the absorbency of certain diapers. For this inquiry lesson, students examine how much water the crystals absorb. They collect data and share their results in class.
