In this activity, students will use a chemical reaction to test for the presence of carbonate in calcite and limestone. Students will drop a small amount of acid on mineral specimens and observe the bubbles of carbon dioxide forming from the reaction of the acid with carbonite minerals.

In this lab activity, students will determine the concentration of a solution of NaOH by titration with a standard solution of HCl. They will also determine the concentration of a sample of white vinegar by titration with a standard solution of NaOH.

In this lab activity, students will test the pH of a number of common substances.

In this informational text, elementary school readers learn about the difference between weather and climate and about components of the climate system. The text can be used to practice visualizing and other comprehension strategies. Available in K-2 and 3-5 grade bands and as an illustrated book as well as a text document, the story appears in the online magazine Beyond Weather and the Water Cycle.

This article highlights resources related to water from the American Museum of Natural History and at-home activities on ice and water.

This activity, which centers on Antarctica, challenges students to research and create the answers and questions for a game of classroom Jeopardy. The printable six-page handout includes a series of inquiry-based questions to get students thinking about Antarctica and guidelines for conducting additional research, illustrated activity directions and a worksheet that helps students craft their Jeopardy-style answers and questions.

In this activity, students will understand the effect of concentration, catalyst, and temperature on equilibrium reactions.

In this lesson, students use Schoenbein paper to test for the presence of ozone in the air through a reaction between ozone and potassium iodide that produces a purple color.

The purpose of this resource is to quantitatively evaluate the accuracy of a classification system. Students sort birds into three possible classes based on each bird's beak: carnivores, herbivores, and omnivores. Students compare their answers with a given set of validation data.

This is an lesson about spectrographs. Learners will build and decorate their own spectrographs using simple materials and holographic diffraction gratings. After building the spectrographs, they observe the spectra of different light sources. Requires advance preparation to spray-paint the inside of the containers black the day before construction. The activity is part of Project Spectra, a science and engineering program for middle-high school students, focusing on how light is used to explore the Solar System.

Students will be able to:Analyze given characteristics for a particular element and identify the type of element and probable location on the Periodic Table. Explain why elements behave in different ways based on their location on the Periodic Table. Recognize patterns and general locations of elements on the Periodic Table based on the type of element and its characteristics. 

CK-12 Physical Science Concepts covers the study of physical science for middle school students. The 5 chapters provide an introduction to physical science, matter, states of matter, chemical interactions and bonds, chemical reactions, motion and forces, and the types and characteristics of energy.

This is a lesson about the Genesis mission. Learners are provided background information about the Genesis mission and the three basic types of solar wind that are being detected by the Genesis Ion Monitor (GIM) and Genesis Electron Monitor (GEM).

This worksheet assesses students' understanding of reversible reactions, chemical equilibrium, and equilibrium constants.

In this lab activity, students observe the effect of various stresses on equilibrium systems.
