Curated OER
Dependence of Light Intensity on Distance
Hopefully you have a sensor interface for your physics class to use with graphing calculators when collecting data with a light sensor. If so, read on. Use this resource for learners to predict and then test whether or not the intensity...
Curated OER
Color Mixing
Students distinguish and recognize the three primary colors used in color printing. In this color mixing lesson, students predict what color will be produced when pigments or color beams are mixed. Students will demonstrate an...
Cornell University
Beam Focusing Using Lenses
Explore optics using an inquiry-based experimental approach! Young scholars use a set of materials to design and build a unit capable of focusing a beam of light. They experiment with different lenses to determine the best approach to...
Curated OER
Color Theory
Learners are able to gain an understanding of primary and secondary colors. They are able to explore about how a mixture of colors makes up white light. Students are able to experiment with the mixing of paint that uses pigments, not...
Curated OER
Attenuation of Light in Water
Students explore what happens to light intensity as depth increases using a light intensity logger. They construct a PVC model to hold water and identify what factors could influence the amount of light attenuation.
Curated OER
Batteries in Series: Voltage and Light Intensity
Students participate in a hands-on activity to explore the relationship between the number of batteries in a series circuit and its voltage. Students identify the relationship between two variables and plot points on a graph.
Curated OER
What do Lenses Do?
Students learn to differentiate between different types of lenses. In this lens activity, students discover how lenses are different and why a specific lens should be used. Students understand how to find the focal point of a lens....
Curated OER
Maximum Power Point
Students investigate how to optimize the power output of a photovoltaic cell using a home-made gnomon stand. They use data collected to create current-voltage and power-voltage curves to determine the "maximum PowerPoint," (MPP) at which...
Curated OER
The Seasons
Students determine the effect of the earth's tilt on the amount of incoming solar radiation throughout the year. They simulate the earth's orbit around the sun using a light bulb and a globe to simulate the seasons. Assessment questions...
Curated OER
Quadrat Studies
Students use quadrats to investigate plants, animals, soils and weather. They answer questions as they fill in each quadrat. They share their information with the class.
Curated OER
Why Is It Hotter At the Equator?
Students investigate the different heating effects of sunlight. They conduct an experiment that demonstrates the way sunlight strikes the equator, the poles and other parts of the globe.
Nuffield Foundation
Biodiversity in Your Backyard!
Take your enthusiastic ecologists outdoors to explore the biodiversity right in their own schoolyard! In preparing for this activity, it may be worthwhile to research websites with local flora to help in the plant identification portion.
Curated OER
Sports Helmets and Impact Testing of Polymers
Students examine the importance of good quality safety gear. In this investigative lesson, students will tests various polymers, collect data, and analyze the data to determine which polymer is best for safety helmets. They will design a...
Curated OER
Black Holes
Students explore what black holes are and how gravity is associated with them. In this space lesson students are given enough information to imagine a journey to a black hole.
Curated OER
Comparing Sunscreens
Twelfth graders use a microcomputer connected to an ultra-violet sensor to compare the relative blocking power of different SPF sunscreens for the UVB region of the solar spectrum.
Curated OER
Succession and Experimental Process
Students describe the roles of controlled, manipulated and responding variables in scientific research. They also identify biotic and abiotic interactions affecting the makeup of a plant community.
