Climate Change
Ninth graders compare the Arctic and Antarctic. In this climate lesson students work in groups, research and complete an oral report or a poster.
Curated OER
Changes Inside Planets
Students relate meteorites to the mantle and crust of asteroids. In this planetary lesson students complete experiments to model the separation of light.

2.4: Metamorphic Rocks
Second graders work with material to simulate changes caused by both heat and pressure. They assimilate what they learned learned in past lessons to explain the rock cycle.
Curated OER
Cooler In The Shadows
Students investigate the concepts of shadows and how they are projected with objects different positions in relation to the sun. They conduct an experiment by observing objects in different positions. Then students record the observations.

Molecular View of a Solid
Why are solids, well ... solid? Take a peek inside a solid substance with an easy-to-use interactive. Science sleuths examine the motion and position of the atoms that make up a solid before drawing conclusions from their observations.
Curated OER
Swinging Observations
Students build a pendulum type swinging apparatus and make specific and selective observations using what they know about scientific observations. They look for regularities of movement, patterns, and systemic changes over time.

Physical Changes and the Water Cycle- Three
Third graders take note of the changes in the water level in a cup of water that is left out. Using a model of the water that depicts a lake and landscape that is being heated by a heat lamp, the students observe precipitation, and...
Curated OER
How Organisms Respond to Changes in their Environment
Students observe the reaction of living cells to mechanical and chemical stimuli by introducing different stimuli to an organism under a microscope and recording the response.
Curated OER
Our Changing Environment-- A Demonstration
Students observe and describe changes in an environment when some of the components are changed. They recognize the process of succession by
preparing a miniaturized environment in which a variety of plants and seeds are grown.

What Changes Occur When Water Freezes?
Students investigate the changes that occur at the molecular level when a liquid becomes a solid. They freeze water in baby jars and observe the changes that occur in the process.

Landscape Observation: How Portland Has Changed
Students read The Lorax and discuss how populations change the environment. Using given photos, students use a Venn Diagram to compare and contrast the Portland of yesterday to present day Portland. They write a comparison paper and...

Chemical Changes by Gems
Seventh graders observe that heat is produced when two substances are combined. They brainstorm how, and then experiment to find out which of two chemicals created the heat.

Activity 4: Alvin Dive, A Mysterious Encounter and Change Over Time
Young scholars receive copies of the Time Series Observations to use for note-taking. They work in small groups to discuss what they see when the outside lights of Alvin are turned on, and off, where the bacteria may have come from. They...

Observing Popcorn
Fifth graders discover the process of boiling water and how it is part of the changing of states of matter. They observe a kernel of popcorn pop in a test tube with water and take notes of how the water changes to the form of a gas....

Using Adjectives to Describe Observations
Seventh graders write observations of organisms based on both audio and video sources. They describe organisms which they view using appropriate adjectives.
Curated OER
Change & Conservation of City Landscape
Seventh graders participate in fieldwork by observing and photographing buildings.
Curated OER
Environment: Understanding Change
Students predict changes that will occur in the environemt after trees are cut down around a house. They focus on changes in the hydrosphere, geosphere, biosphere, and atmosphere. By examining the rings in a tree's trunk, they...

How Do Waves Change a Beach?
Students conduct an experiment on beach erosion. In this earth science lesson, students create a beach model and use tongue depressor to produce waves. They write a journal about their observations.
Curated OER
Bacteria Change Earth's Atmosphere
Tenth graders organize information to explain how photosynthetic bacteria contributed to climatic changes that happened on Earth. Students create a timeline by using a storyboard to tell the story of the change.
Curated OER
Grouping and Changing Materials
Young scholars feel and observe different types of materials. Using the internet, they sort objects based on the materials they are made from and justify their reasons for putting it in a certain category. They identify objects that...

OBSERVING THE ROLES OF MALES AND FEMALES IN THE NURTURING OF THE YOUNG THROUGHOUT THE ANIMAL KINGDOM
Learners watch animal videos to identify and compare the male/female roles of different species of animals. They draw conclusions and compare those roles to those of humans. They discuss how the human male/female roles have changed...

Science: The Changing Life of Air Pressure
Fourth graders observe demonstrations how heated air rises and becomes a low pressure area. After watching several teacher-conducted experiments, 4th graders, in groups, discuss and answer questions in their journals. Finally, they...

Observing Bursts from an X-ray Burster
Students study the use of X-ray data to make size and energy estimates of the source and the processes occurring there. They use XTE observations of the object GRO 1744-28 to determine whether bursts occur periodically and the duration...
