Ready to take your chemistry class on its first big lab adventure? Dive in to differentiation between chemical and physical changes with a thoughtfully designed set of experiments! Partners conduct a series of reactions, describe their...

Young scholars observe the differences between physical and chemical changes in properties. Through the use of an interactive presentation, the students compare and contrast the changes and provide supporting examples of each type of...

Learners distinguish between physical changes and chemical changes. They comprehend that chemical reactions produce new substances with compositions and properites which are different than those of the starting materials. Pupils also...

Students observe what occurs as baking soda is heated. They explain why a chemical rather than a physical change occurred during the procedure. Pupils identify the tpe of reaction (decomposition). Students conduct a glowing splint...

This is one super model interactive! Middle and high school science scholars examine scientific models through a simple resource. Guided, hands-on practice allows them to classify conceptual, mathematical, and physical models. Other...

Teaching is a balancing act! Keep things on an even keel with a comprehensive equilibrium lesson plan. The resource covers reversible and irreversible reactions, Le Chatelier's Principle, and the industrial applications of equilibrium...

Young scholars analyze the causes of corrosion. In this chemistry lesson, students investigate what is necessary to cause chemical changes in matter. Young scholars discover the causes of rust and tooth decay.

Some say cooking is an art—and a science! Scholars scope out the savory subject of molecular gastronomy with a series of related activities. The teacher's guide contains printable worksheets and helpful tips for implementing the lesson.

This is your brain on drugs ... literally! Your neuroscientists-in-training examine the evidence of drug use on the human brain and how neurons change their connectivity when altered by drugs. They then work together to create testing...

The Environmental Protection Agency monitors sensors to track air pollution and set clean air standards. Enthusiastic young scientists use similar sensors to gather data in their area and then apply the gas laws and conservation of...

Students compare the characteristics of a fired porcelain sculpture to the clay used to create it. They discuss the physical and chemical changes that occur in the clay as it is heated and then create their own clay sculpture. This...

Does the human body evolve as quickly as human culture? With a stellar 15-minute video, explore the trait of lactose intolerance. Only about 1/3 of human adults seem to still have the enzyme lactase and therefore, the ability to digest...

Climate models mathematically represent the interactions of the atmosphere, oceans, land, sun, surface, and ice. Part two in the series of four lessons looks at the role greenhouse gases play in keeping Earth warm and has participants...

Do you think the lab smells like rotten eggs? Sorry to hear about your sulfering. A set of five experiments covers many different topics including seasons, gravity, food, precipitation, and photosynthesis. Though not presented as a...

How is sea coral like a thermometer? Part three of a six-part series from NOAA describes how oceanographers can use coral growth to estimate water temperature over time. Life science pupils manipulate data to determine the age of corals...

High schoolers comprehend the different phases of matter. They give examples of each phase and describe the processes of changing between these phases. Students are asked what is plasma? They are asked what is the four phases of...

Scientists have been studying exothermic reactions before they were cool. The lesson begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed to...

Household materials can be used for more than cleaning! In this collaborative experiment, emerging chemists use products such as vinegar and liquid antacid to explore chemical reactions that commonly occur in the human body.
