Curated OER
Rain Drops
Pupils examine drops of water on several materials used on the outside of buildings. They make selective observations on and compare plastic, wood, brick, metal, roof tiles and glass.
Curated OER
Working with Solutions
In this solutions worksheet, students review how molarity is calculated and how to prepare a dilute solution. This worksheet has 5 problems to solve.
Curated OER
Classifying Matter Game
Students identify the different states of matter. In this chemistry lesson, students differentiate the physical properties of the three states. They apply what they learned by playing a team game at the end of the lesson.
Curated OER
The States of Water
Students observe water changing states from a solid to a liquid to a gas.
Curated OER
Physical Difference and Classification
Students use a microscope and observation skills to compare and contrast several physical properties and develop a classification system.
Curated OER
Water Magicians
First graders observe water changing states from a solid to a liquid to a gas. They predict what they think happen to ice cubes as they sit out. They paint water with paintbrushes outside the classroom in the sun and watch the water...
Curated OER
Wet Weather, Wet Climate
Pupils discover the differences between weather and climate in this long-term lesson introduction. They create rain gauges and practice reading rainfall measurements, view a website showing the cloud cover in their location and draw bar...
Curated OER
Metals and Nonmetals
In this elements worksheet, students determine if the given elements are metals or nonmetals. Students give the valence electrons for other elements. This worksheet has 10 fill in the blank questions.
Curated OER
Not a Drop to Drink
Middle schoolers design an experiment to determine which liquid is water. In this chemistry lesson, students perform the experiment as outlined in their design. They record observation and formulate conclusion.
