Students experiment and hypothesize about surface tension and cohesion, using water, ground black pepper, liquid soap, and other household products.

This textbook was developed as a result of a Round 12 Textbook Transformation Grant.

The main objective of this video lesson is to bring the students' attention to the importance of basic and natural sciences in our lives. The lesson will introduce a topic (sustainable energy) that is related mainly to chemistry and is not usually covered directly in a high school curriculum. We hope that this lesson will show students how important and useful the natural and basic sciences are not only for our daily lives, but also for sustainable development. The lesson will present creative and challenging ideas on the topic of alternative energies. It is hoped that students will be inspired by the introduction of these ideas, and that they will develop the confidence to come up with creative ideas themselves. Background for this lesson is based on fundamental concepts in chemistry (mainly), biology, physics and environmental science.

In this activity, learners use a chemical reaction to visualize where moisture forms on the body. Learners use the Minor's iodine-starch test, a diagnostic test that doctors use to detect hyperhidrosis (excessive sweating), to identify where moisture is forming. Learners also use this method to test the effectiveness of different antiperspirants.

The Take Action column in the free, online magazine Beyond Weather and the Water Cycle suggests actions young people (K-grade 5) can take to reduce the impacts of climate change. The magazine examines the recognized essential principles of climate literacy and the climate sciences as well as the guiding principle for informed climate decisions.

This article provides lesson plans about natural resources and energy sources for elementary teachers.

This lesson plan focuses on the concepts of atomic number, mass number, isotope, and nuclear atom. A student quiz is included as an assessment instrument. This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

This interactive activity produced for Teachers' Domain shows the relationship between tectonic boundaries and the locations of earthquake events and volcanoes around the world.

This investigation is a laboratory activity in which the alkalinity of 2 types of substrates (carbonate vs. non-carbonate) are compared on the basis of titration. Students will reflect on the relationship of alkalinity and toxic heavy metals. Teaching ideas from: Project Wet, Water Education for Teachers as found in: "Healthy Water Healthy People, Field Monitoring Guide "(2003)

Watch the ZOOM cast discover which insulator -- newspaper or aluminum foil -- is better at keeping an ice cube frozen longer.

John Orsulak's students work in groups using iodine to test for starch in an array of liquids. Students record and analyze data and conduct the test with their team.

In this video segment adapted from ZOOM, cast members show you how to make your very own electroscope. You can use it to find out if an object is electrically charged.

In this activity, students calculate the cost of the energy used to operate a common three-bulb light fixture, and compare the costs and amount of CO2 produced for similar incandescent and compact fluorescent light bulbs.

The goals of the Thermal Biology Institute's webpage are to present cutting-edge research focused on the biology of geothermal systems, to promote collaboration among researchers and resource agencies, and to advance public education on the biocomplexity of geothermal environments. Information is organized by topic including hot topics, research, current events, outreach, education, and electronic resources.

The pdf file  attached  contain  thermogram  depicting the decomposition of calcium oxalate monohydrate. Stepwise decomposition including the temperatures, the percentage of compund decomposed and the names of the compound formed post decomposition are all depicted in the graph.

Thermodynamics and Chemistry is designed primarily as a textbook for a one-semester course in classical chemical thermodynamics at the graduate or undergraduate level. It can also serve as a supplementary text and thermodynamics reference source.

Prior to reaching households, water is exposed to a variety of treatments designed to render it fit for human consumption and use. One of the first treatment steps is the removal of suspended solids using chemical additives called flocculants. In this activity, students learn about two commonly used flocculants and clean water collected from a local pond or river. They experiment with flocculant, stirring and pH variables.

This interactive activity from the NOVA Web site challenges you to think like Einstein and understand how time travel might be possible.

This is a classroom lab investigation where students use the story of the three bears to discover inadequacies in the story and discover how to make them correct. Convection, conduction and radiation are involved.
