Curated OER
Separating a Starch-Glucose Mixture Using Gel Filtration
Students experiment using the basic principles of gel filtration. They use the gel filtration technique for testing for the presence of specific substances. Students discover that starch is a larger molecule than glucose.
Curated OER
Pesticides and Eggshell Thinning.
Students analyze the calcium content of egg shells as an introduction to the toxic effects of pesticides on biological systems.
Curated OER
Temperature
Several slides compare different temperature scales. Thermal expansion, heat transfer, and Maxwell speed distribution are also explored. The last two slides seem unrelated to the topic of heat, but are easily left out of this otherwise...
Curated OER
Conserving Chemical Resources
Students balance chemical equations and solve for gram to mole ratios.
Curated OER
pH of Household Products
Tenth graders are provided with a piece of paper such as index, art, construction, or computer coating it with a universal indicator. They use cotton swabs HCl and NaOH to draw a picture repeating the same process using lemon juice and...
Curated OER
Substances And Chemical Reactions
Students watch and predict chemical reactions when different substances are mixed together. They differentiate between solid, liquid, and gas.
Curated OER
Invisible Ink - Demonstration
Learners observe a demonstration that shows that the indicator, phenolphthalein, is a chemical that displays different colors depending on either the acidity or the basicity of the environment. They use the substance to reveal secret...
