Wilson Bentley and Snowflake Crystals
Fifth graders read the book, 'Snowflake Bentley' by Jacqueline Briggs Martin. They gather and make a list of information about snowflakes and crystals. Then they make their own real crystal snowflake creation and observe the crystals...
Curated OER
Milk Makes Me Sick
Students experiment with lactase to find out how milk sugar is broken down in the body. In this enzyme lesson plan, students use glucose strips to investigate the breakdown of lactose into glucose and galactose for milk digestion in the...

Make A Crystal Snowflake!
Students make a crystal snowflake decoration out of string, pipe cleaners, food coloring, boiling water, and more. In this snowflake lesson plan, students let it dry over night and see crystals in the morning.
Curated OER
EggCELLent Diffusion
Students examine and discuss the concepts of diffusion and osmosis. They observe the effects of diffusion on eggs by recording the change in an egg's size and the amount of liquid substance that remains.
Curated OER
Using Chromatography to Identify Unknowns
Learners are introduced to the concept of chromatography. They practice using new vocabular and observing experiments. They answer discussion questions to end the lesson plan.
Curated OER
Water Pollution
Students study four samples of "rain water". They asked to determine the pH of the samples and then to neutralize them. Students are asked to predict any negative effects which might be associated with water having a low pH and to...
Curated OER
What is Biocomplexity?
Students dicuss different aspects of biocomplexity. They demonstrate synthesis of complex concepts by creating before and after posters expressing how the concepts of biocomplexity have ben internalized. Students define the term...
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.

Ice Cream Blizzards
Fourth graders explore whether the making of homemade ice cream is a physical change or a chemical change in a lab experiment. Students identify states of matter, describe the physical properties of states, and collect temperature data...
Curated OER
Where in the World is Carbon Dixoide?
Students conduct experiments designed to detect the presence of CO2 by using a BTB that changes color (blue to yellow) in the presence of CO2. First, students experiment with the CO2 from combining vinegar and baking soda. In part two,...

Impact of Exotic Species on Lake Ecology
Students examine the effect of foreign species on various habitats. In groups, they identify the population dynamics of the zebra mussel. They calculate averages and graph data from Seneca Lake in New York. They develop hypothesis...
Curated OER
Superballs
Students mix two different solutions to become more familiar with molecules and polymers. In this chemistry lesson, students decide whether or not the reaction between two solutions is chemical or physical. Students then observe the...
Curated OER
Stream
Students examine stream waters. In this scientific inquiry lesson, students "explore" wetlands as they participate in a demonstration that reveals information about steam waters and insects.
Curated OER
Water Quality
Students examine water quality and how to improve it, how to measure it and how it relates to human activities. In this water quality lesson students sample water from different sources, and test the samples.
Curated OER
Hatching Chickens
Students learn the importance of caring for eggs as they hatch chickens. In this egg hatching lesson, students observe what happens when eggs are hatched into chickens by completing a e-worksheet and watching a web based movie.
Curated OER
Milestones in Human Spaceflight
Students investigate the history and goals of NASA and human spaceflight. In this space science lesson, students answer questions about one of seven manned space programs and print pictures from the mission. As a class, students will...
Curated OER
Distant Relatives
Students investigate observations between widely separated populations of anchialine cave fauna. In this biogeography lesson students discuss theories that could explain the given observations.
Curated OER
The Robot Explorer
Young scholars design a robotic vehicle to explore underwater caves. In this robot technology lesson, students brainstorm, research, and report about a robotic vehicle design capable of sensing objects and taking appropriate actions to...
Curated OER
Straw Chromatography
High schoolers separate food coloring using liquid chromatography. For this chemistry lesson, students explain the effects of different solvents on the rate of separation.
Curated OER
Rusting-A Form of Oxidation
Students observe the rusting process in the lab. In this chemistry lesson, students rank metals according to their conductivity. They give real world applications of this activity.
