Adventures With Super-Absorbers and Substance Solubility

There is a solvent called aqua regis that can dissolve gold! After observing a solubility demonstration, groups receive four known crystals and one unknown. Based on the demo, they design an experiment to determine the identity of the...

Gravity is just one consideration when determining human habitability on a new planet. The lesson connects four different units and starts with connecting the various systems: planetary systems, human body systems, etc. After scholars...

Why does some ink bleed through paper, and other ink doesn't? Practice some paper chromatography to separate the colors from a pen with an interactive experiment for middle and high schoolers. Learners use a variety of solutions to track...

Are "polar" bears soluble in water? This inquiry-based STEM lesson plan allows students the opportunity to formulate a testable question on solubility, create a procedure to investigate the question, collect data, and draw conclusions.

Here is the first of four poignant lessons on how humans and oceans interact, even if people live far from the coast. This particular lesson also examines studies that are taking place in Antarctica of how climate change is affecting the...

Stir chocolate drink mix into hot and cold water to see if there is a difference in how quickly it dissolves. Number three in a six-instructional activity unit on dissolving, this installment investigates the effect of temperature. If...

Blow the minds of young scientists with this collection of inquiry-based investigations. Based on a series of eight videos, these "hands-on, minds-on" science lessons engage young learners in exploring a wide range of topics from making...

One of the learners in your class might be the first human to step onto the surface of Mars, or the first to design a spacecraft that collects data from the red planet. Prepare them for the adventure with a set of 24 lessons, complete...

Sal uses the substances, salt, and water to illustrate solubility of a substance. We all know that salt will eventually dissolve in water, but if the temperature is increased, that process happens much more quickly. He explains why this...

Students investigate which diaper is the most absorbent. In this chemistry instructional activity, students calculate how much water is absorbed by diapers. They identify an unknown powder based on physical and chemical properties.
