PLANTS LOVE AIR
Students identify that plants cannot develop adequately without air and predict what happens to the leaf of a geranium brought to class. They draw a picture of what they think the leaf will look like after a week of being covered....
Curated OER
Solids in Bottles
Pupils use funnels to put the five solid materials into clear bottles with caps. They observe how the particulate materials look, sound, and move when they shake and roll the bottle. Finally, students write "sound and touch" poetry.

Build a Solar Sill
Students explore how to generate fresh water from seawater. In this solar energy instructional activity, students use the power of the sun, evaporation, and condensation to generate freshwater. Students focus on the water challenges in...
Curated OER
From Ground to Water
Students explore groundwater and issues relating to groundwater. They discus the problems involving groundwater. Students write a newspaper story addressing groundwater problems. They create a comic strip addressing groundwater...
Curated OER
Effects of the Sun on Our Planet
Pupils examine the effect of different types of light on the Earth. They discover the role of evaporation and the effects of the sun on the magnetosphere. They also observe different solar phenomena.
Curated OER
Heating the Atmosphere
Students construct a thermograph for maximum and minimum temperatures for the 2-week period. They illustrate how the earth's atmosphere is heated by convection and conduction currents and evaporation of water.

Rainwater Harvesting, A Practice for Puerto Rico?
Students identify the various sources of water in Puerto Rico. In groups, they research the various ways people in the country gather their water. They also analyze the reasoning behind water catchment systems to end the lesson.
Curated OER
Get to know H2O!
Students investigate scientific concepts and inquire about physical states of matter. The transition of water is considered and is easy to facilitate because of its abundance and often observed physical changes.
Curated OER
Determining the Amount of Transpiration from a Schoolyard Tree
Young scholars calculate the amount of water transpired by a single leaf and estimate that transpired by an entire rainforest.
Curated OER
Observing Buffers In Lakes, Ponds And Streams
Young scholars observe the effects of limestone on the acidity of water. Some areas of the nation have a lot of limestone in lake bottoms and in soil, which helps neutralize the effects of acid rain. Students see this effect first hand.
Curated OER
Structure-Property Relationships
Students explore the structure and property changes of water through videos and classroom discussion. They are introduced to atomic arrangement of solids by looking closely at carbon in different forms, such as graphite and diamond....
Curated OER
Law of Conservation of Mass
Students work in small groups. They grab a handful of ice, and place the ice in an empty beaker of ice using a triple beam balance. Students heat up the beaker of ice over a hot plat until the ice has changed into water. They measure...
Curated OER
Exploring Phases of Matter
Students discuss and experiment with the phases of water. In this phases of matter lesson, students recognize the different states of matter. Students measure and record changes and understand when the state changes.
Curated OER
Pop Bottle Terrarium
Students make terrariums out of bottles, pebbles, cuttings from other plants, and water. In this terrarium lesson plan, students learn about recycling by using household items to make terrariums.
Curated OER
Activity #8 Simulation of Oil Spills
Students conduct an experiment to simulate an oil spill and identify the characteristics of oil in water. They evaluate the effectiveness of various cleanup methods. They discuss the how to clean up an oil spill, and what causes oil...
Curated OER
Trophic Relationships, Cycling of Chemicals, Human Impact on Ecosystems and Conservation
Students explore how the energy flow through a system is related to trophic levels. They investigate how organisms affect the cycling of elements and water through the biosphere. Students participate in lab activities to observe ways...
Curated OER
Biodiversity in Illinois-Pond Habitats
Second graders construct a pond habitat in the classroom using a small swimming pool partially filled with water, real cattails, a tree log adjoining, and plastic animal life appropriate to a pond setting. They examine the frog in detail...
Curated OER
Circles in the Landscape: Irrigating Oklahoma Crops
How do you grow crops in a area with insufficient rainfall? Why you irrigate, of course. Class members investigate irrigation systems by designing a system of their own. After examining irrigation related concepts, vocabulary terms, and...
Curated OER
The First Farmers
Pupils investigate how constant irrigation, with repeated evaporation of water eventually ruined farm land in southern Mesopotamia. They discuss the development of irrigation.
Curated OER
Here Comes the Rain
Second graders help to prepare a model of the water cycle before the conduction of this experiment. They use the model in order to observe changes that happen to water when it changes states of matter.
Curated OER
TRANSPIRATION IN PLANTS
Students define the hydrologic cycle, define transpiration, name the three parts of the hydrologic cycle, and record the amount of moisture given off by several green plants.
Curated OER
Set the Stage
Students observe evaporation in a controlled environment. Evaporation is the change of liquid water into water vapor (a gas). The rate of evaporation is determined by many factors such as air temperature and humidity, liquid temperature...
Curated OER
Understanding Salinity
Students discuss why the ocean is salty. They discuss what salinity is. Students are told that is they want to know how much salt is in a body or water, they would use a special scientific tool. They complete an Estuarine Layers science...
