Curated OER
Chemistry: Acids and Alkalis
Students identify substances that are acids and alkalis. In this acids and alkalis lesson, students conduct tests to determine if given substances are acids or alkalis. They test substances and explain the different qualities that make...

Getting Down to Basics (and Acidics)
Seventh graders investigate acids and bases. In this acids and bases lesson, 7th graders use household items such as coffee, lemons and soap to define acids and bases. They observe a demonstration to show how indicators determine if a...

Titration: Standardization of a Base and Analysis of Stomach Antacid Tablets
Titration experiments don't have to give your high schoolers a stomachache. Study the ways to titrate an acide with a base in an engaging science experiment, which involves creating solutions and performing titrations. Pupils prepare a...

Tritration: Standardization of a Base and Analysis of Stomach Antacid Tablets
Do antacid tablets really do what they claim? An experimental lesson attempts to answer this question. Individuals practice the process of titration during the first part of the experiment. They then use those skills to neutralize an...

No Stomach for It: Investigating Antacid Medication
You won't get a stomachache doing an investigative experiment. Pupils simulate the effect of antacids on stomach acid. Obviously, they won't be using real stomach acid; diluted hydrochloric acid serves this purpose.
Curated OER
Acid Rain And Geology
Students become aware of the environmental problems caused by acid rain and study the pH scale. They determine acidity of local rain water.
Curated OER
PH Neutralization For Pollution Control
Students recognize whether a solution is an acid or a base. In this acids and bases lesson plan, students use chemicals and identify if those chemicals are acids or bases. From the conclusion, students will be able to identify if the...

Investigating Factors Affecting the Breathing Rate of a Locust
Do animals breathe faster when given more oxygen or more carbon dioxide? Young scientists observe the respiration rates of locusts under a variety of gas concentrations to answer that very question. They collect data, analyze the...
Curated OER
Chemical Reaction in a Baggy
Tenth graders observe various chemical reactions in the lab. For this chemistry lesson, 10th graders list the indications that a chemical reaction took place. They give real life examples of reactions they see everyday.
Curated OER
Measuring Reaction Rates
In this chemical reaction worksheet, students determine the rate of consumption or rate of production for given reactions. This worksheet has 14 problems to solve.
Curated OER
How to identify a physical change from a chemical change
Young scholars 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
Chemistry: Metals and Non-Metals
Young scholars conduct an experiment to test the reactivity of metals and non-metals. For this chemistry lesson students test metals with different chemicals to observe the reaction. The results are used to categorize the metals.
Curated OER
Solubility and Chemical Changes in Groundwater
Students test pH of water before and after it travels through different substrates (igneous pebbles and limestone) to detemine how soluble materials can affect groundwater. They answer questions such as: What happended to the pH of the...
Curated OER
Is There Really Life on Mars?
Students examine the work of scientists and determine how they test their theories.
