Learners explore atomic measurement in the first activity in a series of 36. Through readings, activities, and questions, classes review standard SI units, learn about Avogadro's constant, and use it to help them calculate moles. They...

Do you think chromatography paper suffers from separation anxiety? Young chemists make soap, slime, silly putty, and experiment with chromatography in this lesson. The material includes clear instructions for each experiment along with...

Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...

Beginning biologists demonstrate their grasp on cellular respiration, photosynthesis, and energy flow though ecosystems when completing this worksheet. Fifteen multiple choice and short answer questions test their knowledge. Because of...

Students are often confused by the huge amount of information and detail that can be learned about respiration.  This is a great presentation summarizing the main 4 stages of cellular respiration. It is clear and uses diagrams and...

Future chemists practice laboratory techniques by creating a monochloramine solution. The objectives are to use of dilution, 9concentration, and measurement skills and to prepare a solution that will be used in a water treatment...

Here is a well-designed science lesson plan that shows learners that everything that organisms do in ecosystems, including running, breathing, burrowing, growing, requires energy. After a thorough discussion of their own eating and...

Scholars generate and collect pure oxygen through a decomposition reaction of hydrogen peroxide in the fourth lesson of an 11-part series. Then, they complete six investigations into the properties of oxygen.   

Through a hands-on activity, an acetone-spinach solution is pre-made and learners use this solution to separate the pigments found in spinach using chromatography. The comprehensive resource includes an analysis and conclusion...
