Brine Shrimp Hatching Experiment
Learners hatch brine shrimp in a classroom experiment. For this hatching brine shrimp lesson, students participate in two-week lab in which they study how brine shrimp hatch under different conditions. They record data about the control...

"Pennsylvania Watersheds, Many Ways to the Sea"
Students trace a molecule of water through the water cycle including each of its three loops. They describe why evapotranspiration demands the largest portion of total precipitation falling on a forested watershed.
Curated OER
Secret Agents of Dissolved Oxygen
Students determine the changes in different types of water in a sealed container over time. They investigate how to measure dissolved oxygen, temperature, and carbon dioxide with calculator or computer probe-ware. Students determine the...
Curated OER
Meet an Aquatic Snail
Students explore aquatic snails. In this life science instructional activity, students create a class list of questions about aquatic snails and begin to observe aquatic snails in the classroom. Students record observations.
Curated OER
Observing Brine Shrimp
Students observe brine shrimp eggs, create an appropriate environment for their survival, and observe their growth.
Curated OER
Water Currents
Middle schoolers demonstrate how ocean currents are influenced by changes in density. They discover that temperature and salintiy affect density as well. They participate in a short experiment to end the lesson.
Curated OER
Photosynthesis: Intake of Carbon Dioxide - Production of Oxygen
Students, after a long-term observation of photosynthesis with aquatic plants, assess the benefits of photosynthesis towards all living organisms. They explain in their own words the two cycles within photosynthesis. Guided discussion...
Curated OER
CREATE A CAVE
Students investigate the concept of caves by conducting an experiment. The lesson contains background information for the teacher. They collect data while making observations and write a review of the concept once the experiment is...
Curated OER
Waves Lesson Plan
Students demonstrate an understanding of tsunamis and possible causes. In this investigative lesson students view a video and explore earthquakes and movement of tectonic plates.
Curated OER
Boat Design
Students build a boat and make predictions. In this geometry lesson, students design a cargo boat. They must show that the boat they designed can carry the cargo.
Curated OER
Wagons Test
Students examine the characteristics of different biomes. In this ecology instructional activity, students design biomes where given animals can live. They discuss the design within the group and share it with the class.
Curated OER
Environmental Differences
Students observe and conduct an experiment to see whether differences in salinity (the environment) have an affect on the hatching rate and survival of brine shrimp.
Curated OER
Snail Observation Exercise
Students are given a pond snail in a clear glass and asked to make observations on the snail's form and behavior. One of the key ideas is that seemly common subjects (like snails) often have surprising or interesting properties.
Curated OER
Does a change in pH affect the growth and survival rate of aquatic plants?
Students determine if changes in pH affect the growth and survival rates of aquatic plants. They evaluate the optimal pH levels for the growth of aquatic plants.
Curated OER
Lotic Environment
Learners assemble a classroom river model as an example of a lotic system. They control and measure biotic and abiotic information for the in-class system and compare data with a lotic system in a natural environment.
Curated OER
Learning Lesson: That Sinking Feeling
Students discover the origin of the Great Ocean Conveyor. They participate in a demonstration showing how salinity and temperature affect water density. They also examine the new sea ice that forms every winter.
Curated OER
Lotic Environment Lesson Plans
Students create and conduct experiments on a "classroom river habitat." They manipulate the biotic and abiotic factors so that they are able to compare an artificially prepared river model to a naturally occurring lotic ecosystem.
