This video segment adapted from A Science Odyssey looks at the invention of nylon.
Students learn about material balances, a fundamental concept of chemical engineering. They use stoichiometry to predict the mass of carbon dioxide that escapes after reacting measured quantities of sodium bicarbonate with dilute acetic acid. Students then produce the reactions of the chemicals in a small reactor made from a plastic water bottle and balloon.
Learn where diamonds originate and how inclusions trapped within diamonds help geologists determine their age in this video segment from Nature.
The students will investigate how one liquid will change the color of another.
In this video segment adapted from NASA, astronomer Michelle Thaller introduces the world of infrared light and demonstrates how infrared cameras allow us to see more than what the naked eye can perceive.
This video segment adapted from NOVA illustrates why carbon is at the center of life on Earth. It also asks whether carbon-based life might exist on other planets.
Science is super cool -- especially when ice and salt are involved. Supercool water to below its freezing point and then discover how to make ice on demand in this experiment.
This activity seeks to have students model the process of science by recording quantitative and qualitative attributes of reactants and products in three separate experiments with the purpose of examining the relationship between the original reactant(s) to the final product(s). Students record the mass and volume of reactants and products and independently calculate mathematical relationships between the reactant(s) and product(s). They also record their observations of any physical changes that occur.
Why are some substances liquids, while others are solids? Why are some substances harder than others? Why is water essential for life on Earth? This pathway provides resources for answering these questions by looking at the types of intermolecular foces that exist between particles, and the effect that these forces have on the macroscopic properties of substances.
This activity is an introductory activity where students observe the characteristics of ionic compounds and crystals They also work on making observations and writing hypotheses.
An elementary introduction to chemistry vocabulary, tools and concepts used in science curriculum.
This is an introductory lab for Environmental Science, investigating the bulk density of soil and water holding capacity.
This animation from KET's distance learning physics course demonstrates the mathematical formula for a scientific law as it applies to light.
This activity is a classroom lab activity that demonstrates chemical change in a dramatic way using a few inexpensive, easily obtainable materials.
This activity is an extension to standard labs that have students generate a pH curve from strong acid/strong base data. Students are asked to predict and test how the the titration end point will shift when titrating vinegar (a weak acid) with NaOH (a strong base).
This activity is an inquiry where students will design an electrolytic cell that produces work in the form of lighting a bulb.
This classroom lab allows students to develop skills of the scientific method while exploring the characteristics of enzymes.
This activity is an inquiry based lab where students determine 3 ways to change the rate of the chemical reaction between hydrochloric acid and alka-seltzer.
This activity is a classroom investigation where students separate pigment in dyes in order to learn about mixtures and solutions. They use chromatography to design and experiment with a single variable to answer a question about which ink will separate the most - has the greatest variety of pigment.
This activity is a lab investigation where students design an experiment to extract pigments (AKA chromatography) from different colored, water soluble markers.
