Christa's Lost Lesson: Effervescence
How are chemical reactions affected by gravity? Learners explore the phenomenon of effervescence as part of the Christa's Lost Lessons series. They compare findings in an experiment on effervescence to a video of a similar experiment in...
Polar Trec
Down to the Deep Virtual Lab
At a depth of 3,000 m in the ocean, the pressure is 300 times that at sea level! In the activity, individuals predict what will happen to Styrofoam cups submerged 3,000 meters into the ocean. They then convert these units to soccer...

Dissolving Salt
Fifth graders, in groups, complete an experiment/activity in which they dissolve salt in a cup of hot water and then observe what happens as the water evaporates over the next few weeks.
Curated OER
Mystery Polymers
Learners examine how some natural substances are polymers. For this polymer lesson students complete a lab and give examples of a physical change.
Curated OER
Pressure in Fluids
Students study the properties of fluids under different circumstances. In this pressure fluids lesson students view a demonstration, complete an activity and describe what they learned.
Curated OER
Emulsion_ Compulsion
Students experiment with common household products to determine the properties of emulsions and how they fit into the classifications of matter through this series of lessons.
Curated OER
Do You Dig Wetland Soil?
Students study the physical differences between wetland and upland soils. They match colors to the different levels of the soil after digging holes. They create soil color charts and chart the texture of the soils.
Curated OER
Run-off Race
Students create wetland models in pans and use them to experiment to see how plants help slow the flow of runoff water and keep our waterways clean.
Curated OER
Plastics and Rubber: What's the Difference?
Students observe how to classify things into groups based on physical properties. In this plastic and rubber lesson students group and sort items to help them to better identify properties.
Curated OER
River Study
Students study physical features of a local stream. They study how to identify water features on topographic maps.
Curated OER
Investigation of Timbre
Students design an experiment to analyze the timbre of different instruments. In this physics lesson, students analyze the missing quality in sound. They discuss their results in class.
Curated OER
Pure Substances and Mixtures
Students compare and contrast the properties of substances and mixtures. In this chemistry lesson, students simulate spontaneous mixing by performing a short class activity. They differentiate heterogeneous and homogeneous mixtures.
