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.

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.

Repeated motion is present everywhere in nature. Learn how to 'make waves' with your own movements using a motion detector to plot your position as a function of time, and try to duplicate wave patterns presented in the activity. Investigate the concept of distance versus time graphs and see how your own movement can be represented on a graph.

This activity is an extension activity following a unit study on mixtures and solution. Students will use variables to create a unique cola formula and present their findings.

This Chemistry experiment investigates physical changes, solutions, supersaturated solutions, and states of matter.

In this short demo/activity, a balloon with baking soda in it is stretched over the mouth of a flask or bottle containing vinegar. The balloon is tipped so that the baking soda falls into the vinegar, and the reaction creates carbon dioxide, which inflates the balloon. The activity is part of the children's book, The Air We Breathe.

In this video segment adapted from ZOOM, cast members make a seismometer and experiment with different ways to make it register movement.

Where the tropical ocean meets the sea, a peculiar kind of plant thrives in shallow, salty water. These mangrove plants are incredibly important for shoreline protection and baby fish habitats. In this video, Jonathan investigates life in mangroves by visiting both Caribbean and Pacific mangroves. Please see the accompanying study guide for educational objectives and discussion points.

This video adapted from NASA explains how a magnetometer determines magnetic fields around planets.

TED Studies, created in collaboration with Wiley, are curated video collections — supplemented by rich educational materials — for students, educators and self-guided learners. In The Deep Ocean, aquatic explorers take the TED stage to share what they've seen in the abyss of Earth's last frontier: the deep ocean, home to massive underwater mountains and valleys, giant smoking chimneys and an amazing array of animals.
