How can you pick up an ice cube with a string? Watch this video segment adapted from ZOOM to see how salt can help.

Google Slide presentation discussing changes of the new chemistry standards with the old standards. Examples of lessons that could be used based on the revised standards that incorporrate science and engineering practices, cross cutting concepts, and disciplinary core ideas.

Video clips from federal and regional agencies show scientists at work with tools used to collect data about the climate and weather. This article, from the free, online magazine Beyond Weather and the Water Cycle, will help students visualize the tools and how they are used in the atmosphere, at sea, and other hard-to-access locations.

Take control of a virtual car and learn how vectors are used to represent velocity and acceleration in this interactive activity developed for Teachers' Domain. Grades 6-12.

In this adapted video segment, ZOOM guest Laura shows us some of the natural features of Yellowstone National Park, including geysers, hot springs, fumaroles, and mud pots, as well as some of the wildlife.

This interactive resource adapted from the National Park Service illustrates the difference between explosive and effusive volcanic eruptions as well as the hazards that can result, including lahars, tsunamis, and lava flows.

This interactive resource adapted from the National Park Service illustrates the variety of landforms and features created by volcanoes. Featured are calderas, craters, fumaroles and other geothermal features, igneous rocks, lava flows, lava tubes, and maars.

Ever wonder how a battery works? This segment highlights voltaic cells, their various components and how they operate.

In this issue of the free online magazine, Beyond Penguins and Polar Bears, explore what the polar regions can teach us about the water cycle and the states and changes of matter. Find lesson plans about the many forms of water, ice, and snow found in the polar regions and how to use science notebooks to integrate literacy and science.

In this interactive activity adapted from the University of Utah's ASPIRE Lab, learn how to measure wavelengths and see how wavelength affects the color of the light that we see.

There's no need to don a space suit if you want to experience weightlessness. In this video segment adapted from ZOOM, two members of the cast drop a cup of water with holes in it to demonstrate how free fall can create a momentary condition of "weightlessness".
Recommended for: Grades K-8

Before any instruction occurs on concentration, students use this activity and Tang to build on what they already know about concentration.
Using interactive models embedded in the google doc, students are able to drag and drop to build models of solutions with various concentrations.

This video/animation shows that a molecule of water is made up of oxygen and hydrogen atoms. When oxygen and hydrogen atoms exist alone, their properties are different from the properties they have when they are chemically combined to form a water molecule.

In this animated video segment adapted from NASA, astronomer Doris Daou explains how the forces of speed and gravity keep the Moon in a constant orbit around Earth.

The aim of this lesson is to introduce the concept of Neutralization and its application in our daily lives. Students are encouraged to construct their knowledge of Neutralization through brainstorming sessions, experiments, and mind mapping. This video lesson presents a series of stories relating to Neutralization—beginning with a story of a girl being cured from a stomach ache with the help of Neutralization. Prerequisites for this lesson are knowledge of the basic concept of Neutralization, chemical equations and the pH indicator scale. The lesson will take about 50 minutes to complete, but you may want to divide into two classes if the activities require more time.

Engage in argument support by evidence that the functions of three (nylons, paper, slime) designed macromolecules are related to the chemical structures. Emphasis of the attractive forces within and between the molecules as they relate to properties of the macromolecules.

Students will have to solve the real world problem of locker smell leakage by building an air filter that will cover the vents on the top of a locker. This project goes well with a curriculum on the particle nature of gases and phase changes.

Think of some of your favorite tastes: savory Thanksgiving turkey, buttery mashed potatoes, tangy cranberry sauce, and warmly spiced pumpkin pie. We perceive food's complex, layered flavors through the work of five* types of receptors on our tongues—those that detect either sweet, sour, salty, bitter, and umami (savory). These receptors bind to chemicals in our food and transmit the information about the chemicals to our brains, resulting in a healthy appreciation for the nuances of chocolate, coffee, strawberries, and more.

This interactive resource from the Exploratorium calculates your weight on other bodies in our solar system and offers an explanation of mass and weight and the relationship between gravity, mass, and distance.

Test the pH of things like coffee, spit, and soap to determine whether each is acidic, basic, or neutral. Visualize the relative number of hydroxide ions and hydronium ions in solution. Switch between logarithmic and linear scales. Investigate whether changing the volume or diluting with water affects the pH. Or you can design your own liquid!
