Curated OER
Is Your Blue Really Blue? [Metamerism]
Students learn fundamentals about color perception, and explain the phenomenon called "metamerism". Students learn the three basic components of color perception: light source, illuminated colored object, and the light detector.
Curated OER
The Connection Between Pigment and Light Colors
Students learn the procedure for mixing secondary colors from primary pigments and observe the results of mixing two primary colors.
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
TE Activity: Ohm's Law 2
Students study Ohm's Law 2 after completing an activity about Ohm's Law 1. They determine how long it takes to charge a battery. They examine if it is better to use batteries in series or parallel circuits.

Tints, Tones, & Shades Painting
Students experiment with color mixing, using paints as the medium to discover tint, tone, shade, value and intensity.
Curated OER
Ecosystems and Climate
Students examine climatic effects on ecosystems. They plant tomatoes and observe the differences in plant growth with differences in light. They create picture collages of plants, animals, and insects found in each climate of the U.S.
Curated OER
Generate a Calibration Curve for Chlorophyll a
High schoolers measure and graph the absorbance of light by chlorophyll at a specific wavelength versus chlorophyll concentration. They are given an unknown and determine its concentration from their calibration curve. Students become...
