Creepy Reflection and Floating Finger
In this science exploration worksheet, students use a plastic mirror and a bowl full of water to get a fish's eye view of a water surface. Students follow the directions to conduct this investigation.
Curated OER
Weathering Landforms
Fifth graders brainstorm a list of ways the Earth's surface can change. As a class, they are introduced to the concepts of erosion and weathering and discover how wind and water cause changes to the surface of the Earth. To end the...

Does turnip curling always cause friction?
Third graders become familiar with the effects of force through curling. In this turnip curling lesson, 3rd graders experiment with a turnip curling stone on various surfaces. Students are assess with a new variable and observation...
Curated OER
Heating the Atmosphere
Students construct a thermograph for maximum and minimum temperatures for the 2-week period. They illustrate how the earth's atmosphere is heated by convection and conduction currents and evaporation of water.
Curated OER
Effects Of Weathering
Third graders simulate weathering and erosion using sand and soil. They define weathering and the ways in which surfaces become weathered. Working as a class, 3rd graders complete various activities that demonstrate physical and...
Curated OER
I Don't Think We're in Kansas Anymore (Grades 2-5)
Students give examples of erosion and weathering processes. They determine causes of America's Dust Bowl phenomena.Students define erosion as the condition in which the earth's surface is worn away by the action of water and wind.
Curated OER
Reflection and Absorption of Light
Students use a microcomputer connected to a light sensor and temperature probe to explore the reflection and absorption of radiation for different surfaces. Students follow instructions in this guided inquiry based lab and are then asked...
Curated OER
Playing in mud puddles
Students examine the effects of rainfall on different surfaces and discuss water pollution. They review the water cycle and the uses of water in daily lifestyles. Students discuss the effects of soil run off in streams and rivers.
Curated OER
Activity #17 Co2 From Alka Seltzer
Students observe what occurs when Alka Seltzer tablets are added to water. They explain why water stays in the jar when it is above the surface of the water. Pupils test for the presence of carbon dioxide by conduting the match test.
Curated OER
Newton's First Law
In this friction learning exercise, students will read about fluid friction and examples of fluid friction. Students will also explore the role fluid lubricants have in reducing friction between two surfaces. Then students will answer...
Curated OER
Dough Lake Topology
Learners practice coordinates and measurements, develop 2D, 3D topological map, construct grid with string on real surface, establish "level" fixed point for measurements, take and record data points of elevation, and enter data on...
Curated OER
Frozen Film
Students discover how light reflects off surfaces. In this hands-on demonstration, students examine how variations in color are produced by light interference.
Curated OER
Using Inspiration To Support Logical Reasoning
Students share descriptions of science experiments they have conducted. They create a thin film on the surface of water in order to float light objects and observe that a paper clip does, indeed, float on the surface of the water at...
Curated OER
Temperature Changes: Atmosphere & Ocean
Students observe temperature differences of water and air in sunlight and darkness. They determine that the sun warms the Earth's surface, which controls global currents and climate, keeping the earth habitable. They discover water and...
Curated OER
Mural Background
In this mural learning exercise, students use three techniques to create the surface of the ocean, the deep water of the ocean, and the shore.
Curated OER
Determining the Amount of Transpiration from a Schoolyard Tree
Students calculate the amount of water transpired by a single leaf and estimate that transpired by an entire rainforest.
Curated OER
Photosynthetically Available Radiation (PAR) Measurements
Students calculate the amount of solar radiation hitting the ground at their school compared to the solar constant. They also repeat the experiment at a water testing site and utilize a light probe to measure the light being reflected...
Curated OER
Salt Water Wedge
Students conduct an experiment to observe the properties of both salt and freshwater. They explain why freshwater will stay at the surface while salt water will travel up a river bottom because of density. Students also research the...
Curated OER
Demonstration of Factors Affecting Soil Temperature
Students examine the influences of water and mulch on soil temperature. In this investigative activity students complete a soil experiment.
Curated OER
A Caterpillar's Life
Students use different colors, surface textures, and shapes to create form and meaning to their caterpillar. They also come to recognize that living things have similar needs of water, food and air by teacher reading The Very Hungry...
Curated OER
Plate Tectonics Boundaries
Students discover how to create a model of tectonic plates and study the interactions of these plates as they slowly move on the asthenosphere. They see and experience what happens at each type of plate boundary and why there are certain...
Curated OER
Liquid Level
Students observe liquids in different containers and then explore the concept that liquids have level surfaces. They identify those who are not at the center to reinforce the concept of liquid levels with a representational puzzle and...
