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. 

Scholars find Earth won't support humans much longer and need to identify a planet with water to inhabit. They test four unknown samples and determine which is the closest to water. Then they explain and defend their results.

Seventy thousand different types of soil exist in the United States alone. Young scientists learn about the importance of soil to the food supply. They test soil for a variety of factors and determine the best place to set up a community...

Mosses and liverworts do not have any vascular tissue, unlike other plants. Young scientists learn more about these rootless plants through hands-on dissection and research on their life cycles as they get their hands dirty for a fun...

Young scientists learn the importance of experimental design and the key elements of an experiment. Through observing videos and designing their own experiments, scholars apply each lesson they learn.

Scholars observe the effects of microwaves before starting a series of eight hands-on investigations. Then they sort waves by wavelengths and learn what connects microwaves to visible light to water waves and more to finish the...

Do scientists really change their minds when presented with new evidence? Young scientists learn about two competing theories they need to decide between. They perform a simulation and have access to actual field data. Then, scholars...

Car crashes provide a good method for studying kinetic energy transfer. Scholars explore energy through hands-on simulated crashes. They work together to design their own experiments and apply the knowledge gained to a situation that...

Scholars practice opening their minds to observations and make reasonable claims during an out-of-this-world activity. After group discussions, pupils perform an experiment, relying on their observational skills, and present their...

Scholars learn not to overreact as they classify chemical reactions. Starting with learning the basics of classification and moving onto applying all of the correct scientific vocabulary, young scientists master chemical reactions. Six...
