Open this lesson by demonstrating the production of acidic carbon dioxide gas by activated yeast. Emerging ecologists then experiment with seashells to discover the effect of ocean acidification on shelled marine organisms. They measure...

Enhance your class' ability to understand solubility. Science scholars examine how temperature and concentration affect solubility using an interesting lab experiment. The introduction and procedure also discuss the relationship between...

These rocks are HOT! Well, they used to be, anyway. Take young geologists on a two-week journey through the life and times of the average igneous rock. Lab groups work together to hypothesize about intrusive and extrusive igneous...

After challenging themselves to correctly choose the form of erosion and length of time required for a given landform to develop, earth science class members model mechanical and chemical weathering with various lab demonstrations over...

Turn your class discussion of rock formation from ho-hum to holy hornfels! Junior geologists gain experience in identifying rock types and rock origins, with an emphasis in hypothesizing the environment needed to form certain...

Enzymes play a role in almost every function in the human body. Scholars explore three variables related to the use of enzymes. They observe a catalase reaction, experiment with substrates, and examine reactions rates. 

Begin a full lesson on climate change by demonstrating how carbon dioxide gas contributes to increased temperatures. Be aware that pressure inside the antacid-containing bottle in Activity 2 may cause the lid to fly off; keep viewers at...

Time to rock out! Discover the "life" cycle of the average rock using an illustrative stations lab and stimulating pairs game. Roll the dice to determine your fate: will it be melting in magma or chilling out to form igneous rock? The...

Mirror, mirror, on the wall ... who's the best chemistry teacher of them all? You'll get the vote for certain after your class completes the Silver Mirror experiment! Partnered pupils use Tollen's reagent and glucose to silverplate a...

Learners discover hazards related to volcanoes and predict the effects these hazards have on people and land. As blossoming geologists explore various volcanic eruptions, including the hazards associated with them, they...

Every living creature can leave a fossil record, yet most fossils belong to extinct organisms rather than ones currently living. Scholars learn about dating rock layers, fossils, and the environment of the past. Pupils understand that...
