This lab helps students to understand the density is state dependent and can change based on the state of the element.

Spreadsheets Across Curriculum module/Introductory chemistry course. Students build spreadsheets to examine unit conversions between the metric and English systems. Spreadsheet level: Beginner.

Are all atoms of an element the same? How can you tell one isotope from another? Use the sim to learn about isotopes and how abundance relates to the average atomic mass of an element.

Through two lessons and five activities, students explore the structure and function of cell membranes. Specific transport functions, including active and passive transport, are presented. In the legacy cycle tradition, students are motivated with a Grand Challenge question. As they study the ingress and egress of particles through membranes, students learn about quantum dots and biotechnology through the concept of intracellular engineering.

KenKen is a puzzle game that helps students develop whole number calculation skills, logical thinking and perseverance. Users complete the interactive grid with the digits 1-4 (or 1-6) so that each digit appears exactly once in each row or column, while also forming a target number using a specific operation. This page provides four new KenKen puzzles daily with a range of difficulty. Each puzzle includes instructions, rules, and a print option.

This video segment highlights how the U.S. military is the single largest user of energy in the nation, but it is also trying to reduce its carbon bootprint. Scenes taped at Fort Irwin and Camp Pendleton show the Army and Marines experimenting with wind and solar in order to reduce the number of fuel convoys that are vulnerable to attack.

" This seminar is designed to be an experimental and hands-on approach to applied chemistry (as seen in cooking). Cooking may be the oldest and most widespread application of chemistry and recipes may be the oldest practical result of chemical research. We shall do some cooking experiments to illustrate some chemical principles, including extraction, denaturation, and phase changes."

This investigation is a lab where students find out if mass is created or destroyed in a closed system. Students will balance the chemical equation to re-enforce their findings.

This investigation is to help reinforce the idea that a mixture can be taken apart by physical means. It will be set up as a contest in which students will have 3 hours of class to separate as much pure substance as they can. These will be broken into percentages based on purity and the amount they have been able to separate. There is no procedure written so students have a completely open and inquiry based activity.

Create a laser by pumping the chamber with a photon beam. Manage the energy states of the laser's atoms to control its output.

This activity can be used to teach concepts how different densities of liquids can be layered and/or how the salinity of water affects the movement of ocean water.

This activity is a whole group guided inquiry activity/lecture where students will learn what dimensional analysis is, how to use dimensional analysis and learn more about why it is so important. It will provide the foundation for moving into stoichiometry.

This activity is an inquiry lesson where students investigate solids, liquids, and gases through a variety of hands on experiments tied into writing and illustration of observable results.

" This class explores the creation (and creativity) of the modern scientific and cultural world through study of western Europe in the 17th century, the age of Descartes and Newton, Shakespeare, Milton and Ford. It compares period thinking to present-day debates about the scientific method, art, religion, and society. This team-taught, interdisciplinary subject draws on a wide range of literary, dramatic, historical, and scientific texts and images, and involves theatrical experimentation as well as reading, writing, researching and conversing. The primary theme of the class is to explore how England in the mid-seventeenth century became "a world turned upside down" by the new ideas and upheavals in religion, politics, and philosophy, ideas that would shape our modern world. Paying special attention to the "theatricality" of the new models and perspectives afforded by scientific experimentation, the class will read plays by Shakespeare, Tate, Brecht, Ford, Churchill, and Kushner, as well as primary and secondary texts from a wide range of disciplines. Students will also compose and perform in scenes based on that material."

In this unit of 8 lessons, students make groups of zero to 10 objects, learn number names for the groups, compose and decompose numbers, and practice writing numerals to record the size of a group. Each lesson includes visual, auditory, and kinesthetic activities and supporting materials, questions to facilitate student thinking and teacher reflection, assessment suggestions, and a link to online applets that support the unit.

In this 6-lesson unit students develop concepts of number, relationships between numbers, and equality. They make groups of 10 to 20 objects, connect number names to the groups, compose and decompose numbers, and use numerals to record the size of a group. Each lesson includes visual, auditory, and kinesthetic activities, as well as student activity sheets, questions for teachers and students, ideas for assessment and extensions, and links to electronic applets.

In this 5-lesson unit students make groups of zero through five objects and connect number words to the groups. They develop counting strategies and use numerals to record the size of a group. Lessons include familiar nursery rhymes and songs, links to interactive applets, and visual, auditory, and kinesthetic activities. Also included are student activity sheets, questions for students and teachers, assessment and extension ideas.

Students wear nametags of an ion and find others throughout the school with whom they can create ionic compounds.
