By All Indications
How do people determine if something is acidic or basic? Learners make their own acid-base indicators using red cabbage and then determine the acidity and alkalinity of different substances. First, they test substances of known pH and...
Curated OER
What is pH and Why is It Important?
Students investigate about acids, bases, and pH and relate this information to the problem of acid deposition. They use pH paper, students test common household substances to determine whether they are acidic, basic, or neutral. Pupils...

Pixel This!
Did the image I drew match the image you saw? By simulating a satellite and a ground station, teams of two transmit data in the form of pixels in order to recreate an image. They use four different levels of brightness, creating slightly...

Climate Change Impacts on Blue King Crabs
Carbon dioxide is not only causing global temperatures to increase, it causes the oceans to become more acidic. Lesson focuses on the blue king crab and the fragility of the habitat due to climate change. Scholars create a concept map...
Santa Monica College
Titration of Vinegar
Titration calculations require concentration. The 10th lesson in an 11-part series challenges young chemists to use titration in order to determine the molarity and mass percent in concentrated vinegar. Analysis questions encourage...
Curated OER
Investigating the Soil
Students explore the Earth's crust by researching pH levels and acidity. In this environmental safety lesson, students identify the pros and cons of acidity within soil and how it affects plants. Students collaborate in a pH level...
Curated OER
Acid Rain and pH
Learners study acidic and alkaline balance. In this acid and pH levels lesson, students read information about pH, the formation of acid rain and its impact on environments. Learners then complete an experiment to learn about the effects...
Curated OER
Investigating Acidity
Learners classify liquids as an acid, base or neutral. They use purple cabbage juice as an indicator to test several liquids in order to group them as acids, bases or neutrals.
University of Waikato
Ocean Acidification and Eggshells
Eggshells and seashells have a lot in common. Learners use the similarities to conduct an experiment that models the effect of ocean acidification on marine animals. Using varying levels of acidic liquids, pupils make observations on the...
National Wildlife Federation
Ghost Town
Around 93 percent of the reefs on Australia's Great Barrier Reef have been bleached, and almost one quarter of them are now dead. Scholars research the sea temperatures, especially around the areas with coral reefs, to make connections...
Curated OER
Acids and Alkalis
This PowerPoint progresses slide-by-slide through all the facts you would want to deliver about acids, alkalis, salts, and the related lab tests. Each slide has one or two facts about a physical or chemical property or behavior. The...
Curated OER
pH
Students test the pH of various solutions. In this pH lesson plan, students use litmus paper to test the pH of household solutions. They compare their results with book charts.
NASA
Cleaning Water
Give young scientists a new appreciation of fresh, clean drinking water. After learning about the ways astronauts recycle their air and water, your class will work in small groups creating and testing their very own water filtration...
Cornell University
What Is Rust?
Why do metals rust differently? Scholars experiment with metal combinations in a hands-on activity. They create unique environments with different metals and compare the rate and amount of rust for each.
Curated OER
Acid Rain Keeps Falling On My Head
Students measure the pH of local rain water. Students map the location of the collected rain water according to pH levels.
Curated OER
Polluted Rain
Students identify and analyze how acid rain can affect the environment. They then explain how air, water, and pollution interact and conduct pH tests to find acidity levels in water. Finally, students become "Pollution Watch Reporters"...
Curated OER
Acid Rain
Learners understand the dynamics of acid rain and its impact on the living and non-living environment. They hypothesize how acid rain affects water pH levels in two lake systems with differing watershed features.
Curated OER
pH and Red Cabbage Juice
Students review properties of materials and define what pH tells them about matter. In this pH levels lesson, students determine whether materials are acids or bases using indicator substances.
Curated OER
Harmful Effects of Acid Rain
Seventh graders are able to demonstrate the harmful effects of an acidic solution. They become aware of the harmful effects of acid rain. Students make predictions before they began the experiment. If vingegar contains acid, then how...
Curated OER
Acid Rain
Students perform experiments to determine how different acids cause acid rain. They measure the pH of the water to calculate the water's acidity. They discover how acid rain dissolves rock materials.
Curated OER
Determining Acids and Bases
Young scholars test various liquids and identify as acids or bases. In this chemistry and pH lesson, the students use purple cabbage indicator to test a variety of teacher-provided substances, then bring in liquids from home to test...
Curated OER
Off Base
Young scholars explain the Chatelier's Principle. In this pH lesson, students identify factors that resist changes in pH of the ocean and why the ocean is becoming more acidic.
Curated OER
Acid Rain in our State
Students conduct internet research on acid rain, a serious environmental problem. They examine the pH levels of rainwater for their state, collect data from their community and investigate the causes and solutions for acid rain.
