Curated OER
The pH scale
Students list the common properties of acids and bases. They classify substances as acids or bases, by using pH and litmus tests and are able to explain the pH scale. They participate in a lab activity which reinforce their understanding.
Curated OER
Chemistry: pH Probe
Students conduct a pH probe of various household products including both bases and acids. In groups, they use litmus paper to test such liquids as amonia, vinegar, and detergent to discover which are acids and which are bases. Finally,...
Curated OER
Blast Off to Learning
Students explain the laws of volume and pressure, identify what a limiting reagent is and why it is important in a chemical reaction, and distinguish between fossil fuels and renewable energy sources.
Curated OER
As a Matter of Fact
Students rotate through various hands-on experiment stations to explore the concept and properties of different types of matter. They compare some properties of solids, liquids and gases and describe how matter changes from one state to...
Curated OER
Acids & Bases: What's the Solution?
Students conduct an experiment called "What's the Solution? Acid, Base or Neutral." to determine the differences between these types of substance.
Curated OER
Making A Natural pH Indicator
Students make their own pH indicator from red cabbage. Red cabbage contains a chemical that turns from its natural deep purple color to red in acids and blue in bases. Students boil the cabbage to get the pH indicator.
Curated OER
Soil Buffering
Students observe the pH change of an acid mixture poured over soil in a filter. Since the buffering capability of soils differs, you may want to do this experiment with several different soil types.
Curated OER
Observing Buffers In Lakes, Ponds And Streams
High schoolers observe the effects of limestone on the acidity of water. Some areas of the nation have a lot of limestone in lake bottoms and in soil, which helps neutralize the effects of acid rain. Students see this effect first hand.
Curated OER
Looking At Acid's Effects On Metals
Students perform an experiment that demonstrates acid rain. The chemical effect of acids on metals may take at least five days for the human eye to see, even though the reaction starts as soon as the acid contacts the metal.
Curated OER
Igneous Rocks/Volcanoes
Students differentiate between the two types of igneous rock and designate the area the rock comes from.
Curated OER
Soil Analysis Lesson Plan
Students practice calculating density and examine examples of the physical characteristics of soil. They solve a "crime" based on the evidence and laboratory investigations.
Curated OER
DNA: What Does It Mean?
Tenth graders explore DNA using online tutorial. They perform their own DNA extraction from a clove of garlic and identify the key components of DNA.
Curated OER
Boom and Fizz
Pupils investigate the differences between a physical and chemical change. They observe various demonstrations involving physical or chemical changes, make predictions, and record what they see, hear, and smell.
Curated OER
The Last Great Canal
Students read about a cholera outbreak in the 1840's. They read maps, predict how cholera moved throughout the country and participate in a lab activity that demonstrates how disease is spread. They compare cholera through time.
Curated OER
Introduction to Volcanoes
Students develop a basic understanding of volcanoes. They watch a PowerPoint Presentation which introduces three types of volcanoes: shield volcanoes, cinder cones, and composite volcanoes.
Curated OER
Scientific Method "Lab Writeup"
Young scholars analyze and experience the scientific method. They discuss the various steps of the method, conduct various experiments, and write a three-paragraph essay regarding their conclusion.
Curated OER
Solids, Liquids, and Gases
Students explore the three main forms of matter: solid, liquid, and gas. They examine concrete examples of each, using their five senses and "experimenting" to find differences in them. They find pictures of each, cut them out and past...
Curated OER
Hot Gas Or Cold Gas Lab
Learners engage in a lab project to study chemical reactions. They use guided questions to help facilitate the lab experience and come to the correct outcomes. The lesson does not contain a true understandable objective. The lesson could...
Curated OER
It's in the Bag!
Eighth graders measure temperature changes and make drawings of the interactions between matter and energy. By measuring the temperature students can conclude if there are changes in levels of energy.
.
Curated OER
Human Impact on the Environment and Pollution
Young scholars illustrate the impact humans have on the environment through analogies and models. They observe demonstrations of human impact and pollution and create a composite picture of how people can have an impact on their...
Curated OER
Identifying Acids and Bases
Sixth graders observe the physical and chemical change that can occur in an acid and a base. For this acids and bases lesson plan, 6th graders use cabbage juice to identify, compare, and contrast acids and bases.
Curated OER
Introduction to Neutraliization
Students explore acids and bases and the process of neutralization.T hey practice volume measurements and observe the neutralization of an acid
directly through bubble formation and indirectly through indicator color changes.
Curated OER
Invisible Ink
Students wxplore acids and indicators by watching a demostration in which "magic" ink appears. They duplicate the demonstration by writing magic messages using phenolphthalein solution and painting the message with vinegar to show it.
