This video segment adapted from Shedding Light on Science describes how astronomical distances can be measured in units of light-years, and how the finite speed of light allows astronomers to study how the universe looked long ago.

This video segment adapted from Shedding Light on Science demonstrates the law of reflection by showing how light energy is reflected off both smooth and rough surfaces at predictable angles.

First-year chemistry students learn the basics of chemical reactions, and then dig deeper to produce unique multimedia demonstrations that will be used in an educational instructional video for a cable channel. Online simulations and microscaled investigations allow students to study many reactions safely in a short period of time. Small groups of students are assigned one of five basic chemical changes (synthesis, decomposition, single displacement, double displacement, or combustion) for further investigation. After careful consideration, each student selects one reaction and demonstration that best illustrates the particular reaction, and develops a slideshow presentation that can be used in the final class video. As a final assessment, students are given a unique "recipe" for a set of reactants, and they are asked to identify the reaction type and the products that are likely to result.

This unit plan was originally developed by the Intel® Teach program as an exemplary unit plan demonstrating some of the best attributes of teaching with technology.

This module is an introduction to the relationship between stoichiometric coefficients, limiting and excess reactant, and theoretical yield.  Includes a worked example asking for theoretical yield given two starting masses, to identify the limiting reactant, and calculate the percent yield from a given hypothetical "actual" yield.

An exercise in which students apply limiting reactants, mass ratios and percent yields to suggest an optimum industrial process. Cost figures are provided but students are told to come up with, and defend, their own criteria for their recommendation.

The job of a synthetic chemist is akin to that of an architect. While the architect could actually see the building he is constructing, a molecular architect called chemist is handicapped by the fact that the molecule he is synthesizing is too small to be seen. With such a limitation, how does he ‘see’ the developing structure? For this purpose, a chemist makes use of spectroscopic tools. How does he cut, tailor and glue the components on a molecule that he cannot see? For this purpose chemists have developed molecular level tools called Reagents and Reactions. How does he clean the debris and produce pure molecules? This feat is achieved by crystallization, distillation and extensive use of Chromatography techniques. A mastery over several such techniques enables the molecular architect (popularly known as organic chemist) to achieve the challenging task of synthesizing the myriade of molecular structures encountered in Natural Products Chemistry, Drug Chemistry and modern Molecular Materials. In this task, organic chemists are further guided by several ‘thumb rules’ that chemists have evolved over the past two centuries.

This video segment of Swift: Eyes through Time provides concrete examples to explain the concept that distance in space equals distance in time.

Loopy dot diagrams uses fruit loops as a manipulative to help students develop the basic skills for making Lewis dot structures to model covalent bonding.

This exercise was designed to address student misconceptions about why the Moon exhibits phases. Using a sketchbook, digital camera, or flex cam, a student sits at the center of a darkened room illuminated by a single light source in a stationary position. Stools are set up surrounding the student in the center and other students take those positions, always keeping their faces toward the center. The center student sketches or take pictures of the faces at each of the positions. Substituting a sphere (such as a ball) for the students' faces provides an even more vivid illustration of the shadowing of the sphere and connects directly to the rationale for lunar phases.

Sample MISA High School Item Set for Energy Production and the Carbon Cycle covering standards HS-ESS2-6 and HS-PS1-4. These items focus on the bond energy involved in the combustion of hydrocarbons and the role of human coal combustion in the carbon cycle.Image source: "Carbon cycle" by Scottish Carbon Capture & Storage at www.sccs.org.uk

A short activity using goldenrod copy paper as an indicator to introduce neutralization reactions. Students describe what they beleive happens during this reaction.

Campaign for affordable textbooks. Web site contains a large catalogue of open textbooks.

The Ancient Egyptians used a naturally-occurring salt from the banks of the Nile River, called natron, to mummify their dead. Natron is made up primarily of sodium carbonate (a very efficient, but relatively expensive, dehydrating material), with about 17% sodium bicarbonate (baking soda). This activity explains how to create your own fish mummy using common baking soda!

Ma.t.che.s. is a project funded by the European Commission in line of the ERASMUS+ program. His main aim is to raise the atractivity of chemistry lessons in school.
On the website of Ma.t.che.s. you will find resources teachers could use for their chemistry lessons:
1. A compendium of action you could do with students. All dealing with chemistry but meant to change students attitude toward chemistry into something positiv.
2. Friendly designed worksheets in German, Turkish, Greek, Polish and Spanish language.
3. Material for different games all dealing with chemistry. All developed for chemistry lessons or a stand-in class.

There is also material about a survey the five Schools in the project did. It's about student's attitude toward chemistry.

The Webpage is in English. The material is in six languages: Greek, Polish, Spain, Turkish and German.

This activity is a guided discovery where students make chemical mixtures using sodium, learn about the Periodic Table, view salt under a microscope, and have a final result of bath salts for the bathtub

This video from KET traces the energy transformations that occur when coal is burned to produce electricity. Some of the mechanical processes are also described.

In this activity the temperature of a reaction is monitored for different concentrations of reactants.

This is a lab designed to allow students to create and collect gas through a simple acid-metal reaction.

In this adapted ZOOM video segment, cast members get hands-on in the recycling process by using old newspapers to make new paper.
