Investigating Contact Angle
Discover the properties of water-loving and water-hating surfaces. In the seventh installment of a nine-part series, scholars explore hydrophilic and hydrophobic surfaces by conducting an experiment. They observe surface coatings,...
Exploratorium
The Dipping Bird
If you have or want to order the dipping bird demonstration, it is useful for showing how evaporation and changes in the pressure of a closed system cause cyclical motion. After teaching about pressure, consider setting this little guy...

Wetting and Contact Angle
Explore terminology related to water droplets. The sixth installment of a nine-part series teaches young scientists about wetting and contact angles between water droplets and surfaces. It also distinguishes between hydrophobic and...
Science Friday
Sublime Sublimation
Dry ice isn't dehydrated water, and young scientists learn why in this fascinating presentation. After watching a video, they complete three different activities using dry ice. Upon completion, they discuss the scientific principle.
Cornell University
The Science of Snowflakes
Who can grow the best crystals? Challenge class members to develop strategies for enhancing growth in the crystals. Through a lab investigation, learners study the properties of crystals and test the effectiveness of different growth...

Learning Lesson: Sweatin' to the Coldies
Students participate in a demonstration to show the change of water vapor to a liquid. They discuss the three states of matter. They examine flash flood safety to end the lesson plan.
Curated OER
Chemistry Is a Gas
Students investigate the gas laws and how they apply to changes in gases. In this gas laws lesson, students use Boyle's Law and Charles' law to show the relationships between pressure and volume and volume and temperature of gases.
Curated OER
Water Desalinization
In this water desalinization worksheet, students will design and construct their own desalinization plant. Then they will describe how they set up their experiment and if it worked or not.
Curated OER
Compare and Contrast
Encyclopedia Brown asks readers to compare and contrast clues to help Kara and her family solve the mystery of the dripping water. A Venn diagram could be used to make visual the similarities and differences between the two rooms.
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
How Does Convection Happen in Our Atmosphere?
Students explore convection and how it happens in the earth's atmosphere.
Curated OER
How Do Clouds Form?
Students describe how they believe clouds form. They observe the different types of clouds they see and identify the types. They examine what affects the size and shape of clouds.
Curated OER
The Water Cycle and Clementine
Third graders sing a piggyback song to explore the parts of the water cycle and then illustrate and label the water cycle in their science journals.
Curated OER
Diseases of the Eye
Fifth graders research diseases of the eye. In this science lesson plan, 5th graders discuss and research eye diseases and complete a worksheet using the information they find.
Curated OER
Aspects of Weather
Students recognize and observe weather phenomena. In this four part weather lesson plan, students are introduced to weather symbols through a story, then use a thermometer to measure water temperature. Next, students observe the...
Curated OER
Precipitation
Students investigate the formation of rain. They experiment by boiling water in a tea kettle and placing ice cubes and water in a pan. They hold the pan of water over the steaming spout so that the steam strikes the bottom and sides of...
