Curated OER
Up, Up, and Away
Second graders observe the changes that water has when there is a change in a state of matter. In this lesson they observe the results of applying heat to water with the end result of conversion to a gas.
Curated OER
Rock Sorting Activity
Students organize rock samples according to their properties. In this earth science lesson, students predict whether they are igneous, metamorphic or sedimentary. They compare their prediction with the actual type.
Curated OER
Hydrologic Cycle
In this science worksheet, students examine the hydrological cycle through the coloring of the picture that graphically organizes the concept.
Curated OER
Boy, Is That Buoyant!
Fourth graders see that salt increases the density of water and creates a condition wherein objects are more buoyant than would be expected under normal conditions. They describe the relationship between heat energy, evaporation and...
Curated OER
Which Colors Absorb the Most Energy?
Students measure the temperatures over time of different colored envelopes in order to explore the different rates at which each color absorbs energy from a heat lamp. They record their data and graph their results.

Exploring the Rock Cycle
An understanding of the rock cycle is essential in geology and earth science classes.
Curated OER
Polymerase Chain Reaction (PCR)
Students explore how PCR works through various activities. In this biology lesson plan, students explain how PCR generate copies of DNA. They simulate the process using an online interactive website.
Curated OER
Thermoelectricity
Students conduct a series of experiments on thermoelectricity. For this physics lesson, students investigate how thermocouple works. They determine the voltage generated when different conductive materials are held at different...
Curated OER
Three Clouds Activity
Students understand how clouds are formed. In this cloud lesson, students participate in three experiments to make clouds. Students complete activity sheets for each experiment.
Curated OER
A Day In My Life
Students brainstorm how they can conserve energy in their daily lives. For this energy lesson plan, students discuss how they use energy and ways to conserve it.
Curated OER
Solar Power
Fifth graders create their own solar panel. They use this experiment to see how the sun can be used as a form of energy.
Curated OER
Parts of a Solar Panel-Part II
Students discover how a mini-solar panel is constructed by behaving like detectives. Students examine an actual solar panel, measure the solar panel's voltage and use drawings to describe what they observe before completing questions...
Curated OER
Three States of Matter
Third graders investigate the three states of matter and the properties of materials as they undergo physical changes. They identify examples of each type of matter, role-play atoms in solids, liquids, and gases, and conduct an...
Curated OER
Pollution Prevention in Schools
Students review P2 concepts they learned in previous lessons and explore how to reduce the pollution in their school. They also examine ways to conserve energy.
Curated OER
Freeze Pops
Students experience problem-based learning as they use prior knowledge of the states of matter to keep a frozen juice bar from melting.
Curated OER
States of Matter
Fourth graders define the term matter. They compare properties of solids, liquids, and gases. They describe how matter changes from one state to another. They classify objects as either solid, liquid, or gas.

Slugs and Snails
Slugs and snails are the focus of this life science worksheet. Student read a selection on these animals, then answer ten comprehension questions. Then, students must draw an "alien portrait" using the characteristics of slugs and snails...
Curated OER
Movement of Air II
In this movement of air worksheet, students determine the deflection of air masses that result from Earth's eastward rotation. Then they describe what winds provide for different trades. Students also identify and describe the imaginary...
Curated OER
Solids and Liquids
Students complete activities to study the properties of solids and liquids. In this states of matter lesson, students investigate the melting and freezing of a range of materials in a virtual experiment. Students melt the substances and...
