Coal Derivatives by Destructive Distillation
Chemists use the destructive distillation technique to produce three derivatives from a sample of bituminous coal. You will find background information, a materials list, procedures, and sample follow-up questions that you can use in...
Curated OER
Environment: Water & Air
The introduction to the lesson mentions a sailor's limited capacity to store drinking water on his ship. Pupils then set up an overnight experiment to remove freshwater from salt water by distillation. There is a math and map activity to...

The Chemistry of Refining Crude Oil
Consider our energy sources: wood, coal, oil, uranium. Learners compare the pollution to energy produced for each. They practice fractional distillation of an alcohol/water mixture to simulate the process of refining crude oil....
Curated OER
The Water Cycle
Observe the stages of the water cycle by completing 3 activities. To help understanding of the water cycle your students can observe evaporation, the formation of frost, vapor and water and the process of distillation which is used to...
Curated OER
Towers of the Lost City
Middle school marine scientists compare the pH change in distilled and saltwater as acetic acid is added one drop at a time. Then they compare the pH change in both when sodium hydroxide is added. This experiment demonstrates the...
Curated OER
What's In Crude Oil?
Students investigate crude oil. In this crude oil lesson, students investigate fractional distillation and use this technique to separate two liquids.
Curated OER
Explore: 5th Grade Dissolved Oxygen
Fifth graders, in groups, use basic science process skills to measure and compare the dissolved oxygen levels and pH levels of distilled, stream, and pond water.
Curated OER
The Energy Debate - Stoichiometry
Students determine crude oil can be separated into useful fractions by a process of fractional distillation. They write a balanced equation for the reaction between a hydrocarbon and oxygen.
Curated OER
Soil pH Effect on Germination of Specific Weeds
Learners collect weed seeds from three varieties of weeds (knapweed, thistle, or toadflax, for example they may choose others in addition to the spotted knapweed.) They sterilize soil for thirty containers, plant seeds in sterile soil,...
Curated OER
Algae--Where does it Live?
Students discover algae. In this science lesson plan, students examine what green algae is and where it grows. Students test the growth of algae in four different types of water: lake water, well water, distilled water and tap water
Curated OER
A Funny Taste
Students participate in a demonstration that illustrates the relative amounts of salt in various bodies of water including the Dead Sea, Sallt Lake, Ocean water and distilled water. They taste and compare various mixtures.
Curated OER
Rain that Ruins
Students participate in a series of experiments to determine how acid rain contributes to the deterioration of buildings and monuments. Using common building materials, students compare the noticeable short-term affects of distilled...
Curated OER
Rain Machine (Solar Still)
Students experiment with a solar still. In this distillation lesson, students find a simple way to use evaporation to make salty water drinkable.
Curated OER
Rusting and the Scientific Method
Students observe the oil can scene with the tin man from a clip from "The Wizard of Oz" and answer the question, "What can we learn about rust from this scene?". They take 2 tubes and 2 nails, adding 1 salt packet to 2 ml of distilled...
Curated OER
A SALT WATER-Y WORLD
High schoolers observe a model of the distribution of the earth's water and compare the relative volumes and percentages of types of water on earth.
Curated OER
Making and Using a Hydrometer
Students build a hydrometer to measure the densities of fresh and salt water samples. They record the water temperature and density and use the temperature, density, and salinity conversion graph to locate the salinity. Finally,...
Curated OER
Still Waters
Students construct a still to turn seawater into drinking water. They estimate the cost of distilling it. They investigate ways to make the conversion more efficient. They track the source of their home drinking water and make a map of...
Curated OER
It's Too Salty!
Students examine water shortage and the process of changing salt water to fresh water. They examine a world map, define key vocabulary terms, conduct experiments involving seeds and salt water and creating distilled water, and illustrate...
Curated OER
Petroleum Poisons
Students discover how harmful petroleum distillates are that are found in the home. They demonstrate how to collect information about consumer products. They also ask their parents about the safety of the cleaning supplies used in their...
Curated OER
Seltzer Breath
Students investigate "indicator" (Bromothymol Blue or BTB) to test for the presence of certain chemicals in liquids and gases. They compare distilled water and seltzer water for presence of carbon dioxide.
Curated OER
Ground Level Ozone Testing
Students prepare Shoenbein Paper to test the ground level of ozone. They dip a strip of their test paper in distilled water and hang it at a data collection site. They determine the relative humidity of the data collection site. Using a...
