Absorbance Curves: Using Spectrophotometers to Quantize the Effects of a Strong Acid on a Buffer
The Henderson-Hasselbalch equation combined logarithmic terms with the application of carbonic acid as a buffer solution. Scholars learn investigate equation and its applications through hands-on experiments. They collect data and...
Beyond Benign
Packed Up Properties
Determine physical properties of potential packaging materials. Continuing from previous lessons in the series, the resource asks groups to identify physical properties of the substances. They test for conductivity, solubility, water...
Cornell University
Light Waves: Grades 9-12
Explore the behavior of light waves with a lab activity. Scholars build new vocabulary through experimentation and observation. Using different mediums, they model reflection, refraction, transmission, diffusion, and scattering of light.
Cornell University
Light Waves: Grades 6-8
Explore the behavior of light with different materials. Collaborative groups determine whether certain materials absorb, reflect, diffract, or transmit light waves. They then measure the angle of incidence and angle of reflection.

Global Warming of the Atmosphere
Scientists know the amount of carbon dioxide in the atmosphere today is higher than at any point in the last 800,000 years. Scholars learn about the amount of thermic radiation absorbed by air and what happens to the rest of the...
PHET
Molecules and Light
Does light affect molecules or does it go right through them? The simulation explores four different types of light: microwave, infrared, visible, and ultraviolet. Scholars alter the energy level of each as it is aimed at seven different...

Albedo, Reflectivity, and Absorption
What is reflectivity, and what does it have to do with the Earth's climate? As reflectivity is measured by albedo, scientists can gather information on Earth's energy balances that relate to global warming or climate change. Budding...

Water Remediation Lab
Water filtration — that's pure genius! Groups test the ability of a water filter to purify water by running chlorine contaminated water through a filter and measuring the chlorine concentrations as they filter the water. They then graph...
Exploratorium
Give and Take
Heat-sensitive liquid crystal sheets are available in a variety of sizes and temperature ranges. Purchase a class set of hand-held sheets and color half of each with a silver permanent marking pen. Learners of light can hold them under a...

What Goes Down Must Come Up
Third graders explore the capillary action of plants. They discover what makes paper "grow" when water is dropped on it. Pupils observe how paper reacts as it absorbs water. Students use a variety of saturate solutions to grow crystals,...
Curated OER
Transport in Plants
Quite a detailed and advanced look at the transport mechanisms of a plant. The absorption and control of sugar and water concentration are explained and will help an understanding of homeostasis concepts and organ specialization.
