Teaching about the Effect of pH on Aquatic Organisms

Demonstrate to your middle school science learners how chalk breaks down in a weak acid. Discuss what affects acidic rain might have on ecosystems. Lab groups then choose one of two questions: "How does acid precipitation affect an...

How is a movie theater like a desert biome? Compare systems to ecosystems with a set of activities that focuses on accessing multiple intelligences and building upon knowledge. As learners discuss the ways elements of an ecosystem depend...

Young scientist use reference materials to research various local aquatic plants and or animals to find out whether they are natives or exotics. They investigate their impacts on people, other animals and the environment. Students...

Introduce organic chemistry through an analysis of flavor. A three-part unit begins with an overview of the components of flavor. Next, scholars prepare esters through esterification. Finally, they examine how all senses have an impact...

You'll feel strongly about this weak acid and base virtual lab! Scholars experiment with the wonders of dissociation constants in a simulated lab environment. The accompanying written work includes buffer preparation, titration curves,...

This site presents everything you need to know about acids and bases and more! Gives a nice description on what acids and bases are, properties of both, strong and weak acids and bases, an overview of pH, and much more.

In this acids and bases worksheet, students complete 32 fill in the blank and short answer questions on acidity or alkalinity. They color molecular diagram according to the key.

Mia's friends are fish-sitting while she is away on vacation. Zoe divulges to Sam that different animals need different habitats, and that there are both freshwater and saltwater ecosystems. Examples of the kinds of organisms found in...

Through a variety of activities, students learn that not all acid and base reactions go to completion, and instead, they establish equilibrium. Acid-base equilibrium expressions have their own constants, ka and kb. Students will perform...

What common chemical includes safety warnings for being harmful if swallowed or inhaled, causes serious eye damage, and needs to be cleaned up immediately if spilled on the floor? Surprisingly, the dangerous chemical turns out to be...
