Our Changing View of the Earth
Students explore the theory of Plate Tectonics. They participate in a simulation in which they re-enact the debate over Plate Tectonics vs. traditional beliefs of stationary continents that were widely accepted during the 1800's and...

Changes in Force, Motion, and Energy
Eighth graders construct various machines and compare the work done by them.
Curated OER
Cell Size Changes
High schoolers examine the behavior of living cells treated with different types of stimuli. They watch an online movie, examine wet mount slides under a microscope, take an online quiz, and analyze data.
Discovery Science Center
Kindergarten Observing, Comparing and Contrasting
Although this is a science instructional activity, it can be adapted to help meet Common Core standards in math as well. Starting scientists describe physical properties of objects and explore three forms of water. To address the Common...

Integrating Physics-Observing and Experimenting to Find Relationships
In this experimental relationship worksheet, students read about direct and indirect relationships between variables in experiments. They answer three questions about relationships between variables.

Changing the End of a Story
Second graders re-write a story. In this alternate endings lesson plan, 2nd graders read Alexander and the Wind-Up Mouse, by Leo Lionni, stopping to discuss the events and predict what will happen next. Students work in groups to come up...
Curated OER
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.
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.
Curated OER
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.

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.
Curated OER
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
What Changes Occur When Water Freezes?
Learners 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.
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.
Curated OER
Landscape Observation: How Portland Has Changed
Learners 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...
Curated OER
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.
Curated OER
Activity 4: Alvin Dive, A Mysterious Encounter and Change Over Time
Students 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 view...
Curated OER
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....
Curated OER
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
It's Still Polaris
Young scholars observe the changing night sky over the course of an evening and chart the circumpolar stars as they traverse the sky in a progression around Polaris. They infer and discuss the cause of the changing star positions.
