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 plan students sample water from different sources, and test the samples.

Hatching Chickens
Young scholars 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
Distant Relatives
Young scholars 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
Students 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 avoid...

A Limnology Study of Drainage Ditches
Learners chemically test water, observe microscopic organisms in the classroom, and screen the sample for macroinvertebrates. They design a reporting sheet that list all the items to be tested and a space to record the results.
Curated OER
Sensational Slime
Pupils predict, observe and draw conclusions while working on an experiment with "slime." Students accurately record observations and draw conclusions about the experiment.
Curated OER
The Connection Between Pigment and Light Colors
Students explain the mole concept and use this concept to prepare chemical solutions of particular molarities.
Curated OER
The Atmosphere and Flight
Students investigate evaporation and condensation, and apply the concepts to understanding cloud formation.

The Hijacker - How a Virus Spreads
Students view a video that presents how viruses attack the body and how the body's immune system responds. They simulate the spread of an infectious disease and establish the identity of the original carrier.
Curated OER
Keeping Milk Fresh
Students identify the risks of spoilage and pathogens in fresh milk. They investigate the farmer's role in keeping milk safe to drink and identify safety procedures used in dairy farming.
Curated OER
Characteristics of Living Things
Students examine the characteristics of living things. They list the differences between living and non-living things, explore areas around the school, and create a Venn diagram for items found in the school areas.
Curated OER
Investigating Convection Currents
Students examine how differences in the temperature and salinity of the water help create ocean currents. They perform an experiment which shows how temperature affects the circulation of ocean water.
Curated OER
How to identify a physical change from a chemical change
Pupils identify the difference between some physical and chemical properties and compare some physical and chemical changes. They design an experiment to distinguish between a physical or a chemical property of their choice.
