In this video segment adapted from NOVA, scientist Mike Garcia draws lava samples at the foot of the active Kilauea volcano to see if it is related to its neighboring volcano, Mauna Loa.

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.

The purpose of this resource is to develop a classification system for a set of objects and learn about hierarchical classification systems. Any set of objects, such as insects or rocks, may be used as well.

This NetLogo model of leaf photosynthesis shows the macroscopic outcome of the reaction.

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.

Concepts underlying the first of the Essential Principles of the Climate Sciences are aligned with topics typically taught in the elementary grades. This article identifies lessons that will help elementary students develop an understanding of how Sun's light warms Earth and how variations in daylight hours are associated with seasonal change. This article appears in the free, online magazine Beyond Weather and the Water Cycle.

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

In this video segment adapted from NOVA, a team of archaeologists and engineers explores different uses of the lever by recreating the engineering feats of the ancient Easter Island peoples.

This multi-part module introduces covalent bonding and Lewis structures as a model of covalent bonding.Starting with valence electrons, a method of connecting unpaired electrons and/or redistributing valence electrons to satisfy the octet rule is introduced.Numerous examples are presented including CO, ozone, and polyatomic ions

How can you lift a heavy metal table using air? In this video segment adapted from ZOOM, cast members succeed in lifting a table using their own breath and a few plastic bags.

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.

Students typically find linear regression analysis of data sets in a biology classroom challenging. These activities could be used in a Biology, Chemistry, Mathematics, or Statistics course. The collection provides student activity files with Excel instructions and Instructor Activity files with Excel instructions and solutions to problems.

Students will be able to perform linear regression analysis, find correlation coefficient, create a scatter plot and find the r-square using MS Excel 365. Students will be able to interpret data sets, describe the relationship between biological variables, and predict the value of an output variable based on the input of an predictor variable.

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.
