Pendulum Lesson Plans Reviewed by Teachers Why Select Other Criteria? Sometimes you only have 45 minutes to review participles before Tuesday's assembly, or you need curriculum you know was reviewed after a certain date. Duration: If curriculum authors indicate how long it takes to implement a resource, i.e. a 30-minute vocabulary exercise, a three-day science experiment, or a two-week expository writing project, we note it for you. If not, our teacher reviewers may indicate an estimated amount of time it would take. When you select a duration in this box, you'll see only resources with that stated duration. Resource reviews that do not include a duration will be excluded from the list. Reviewed After: Limit the resources you see to those reviewed since the date you choose by clicking the box and making a selection.
REACTIONS What is a chemical reaction? Examples of chemical changes, physical changes, and some gray areas. Chemical equations of chemical reactions.Balancing equations. Balancing ionic equations with polyatomic ions. A chemical reaction is material changing from a beginning mass to a resulting substance. A chemical equation is a way to describe what goes on in a chemical reaction, the actual change in a material. Back to the top of Reactions. Chemical reactions, also called chemical changes, are not limited to happening in a chemistry lab. A silver spoon tarnishes. Ag2S An iron bar rusts. 2 Fe2O3 Methane burns. An antacid (calcium hydroxide) neutralizes stomach acid (hydrochloric acid). CaCl2 + 2 H2O Glucose (simple sugar) ferments to ethyl alcohol and carbon dioxide. 2 C2H5OH (ethyl alcohol) + 2 CO2 Alcohol plus oxygen becomes vinegar and a molecule of water. Here are some examples of changes that are NOT chemical reactions. Water boils out of a kettle or condenses on a cold glass. 2 AgNO3 + CaCl2

Global Climate Change Is the global climate changing? Is the world getting warmer? If you look at the graph below of global temperature changes over the past 150 years, the answer would have to be yes. The full story is very complicated. We invite you to actively investigate for yourself the facts, concepts, and theories. We hope you can join us in this important mission of learning, understanding, and acting! What do we know about the Earth's climate in the past? Let's start by examining Global Temperature History… How do we know what the temperature of the Earth was like thousands and millions of years ago when there were no thermometers? We can estimate temperature by other means. What determines global temperature? The Earth is heated by the Sun. So why does global temperature change? Carbon dioxide is constantly moving into and out of the atmosphere in a process known as the carbon cycle. There is a close relationship between carbon dioxide levels in the atmosphere and global temperature. What can we do?
