Molecules to the Max! refers to a movie released in 2009 about the world of atoms and molecules. A helpful discovery guide provides five posters on science topics typically covered at the middle school level. It also explains the...

Here is part one of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas. With grand conversation and up to three demonstrations, learners make predictions about what they think will happen...

Here is part two of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas—and how energy from heat changes its molecules. With grand conversation, two demonstrations, and one hands-on...

Adsorption, not absorption, is when atoms stick to the surface of an object, like water sticking to a grain of sand. An informative lesson delves into adsorption, teaching physical and chemisorption and the factors that affect them....

Due to surface tension, dew — a liquid, is spherical in shape. Learners explore the properties of liquids in activity seven in this series of 36. Beginning with its basic properties such as boiling point and moving through to surface...

The microwave is a staple in many American households, but how exactly does it work? Approach this question from a scientific and practical standpoint, and discover cooking strategies, recipes, and methodologies for the standard...

Lesson 19 in the series of 36 analyzes the element hydrogen and the s-block elements. Through readings, answering questions, and discussion, learners write about and explain their occurrence, physical and chemical properties, and...

Energize the cells of young biologists with an edible life science activity. Engaging students in exploring the inner workings of plant and animal cells, this activity involves using colored jello and various sweet and...

Substances with the same empirical and molecular formula must be differentiated by their structural formula. Part two in a series of 36 has pupils using chemical formulas to calculate how much of a compound is present in a given...

Liquids, gases, and solids are the states of matter in which scholars investigate in a lesson plan that offers in-depth information and engaging activities that look into the three states and the changes their properties make when mixed...

In this first land plants worksheet, students read about the major events that allowed plants to evolve on Earth. Students read about the primary and secondary atmospheres, the formation of the ozone layer to protect from UV light and...

This site helps students construct a model of the arrangement of water molecules when present as solid, liquid or gas. Includes background information, lesson plans, links to standards and assessment ideas.

Page uses movies and 3D images to explain how properties of water relate to polarity and hydrogen bonding.

[Free Registration/Login may be required to access all resource tools.] This study guide summarizes key points about the three states of water. Includes a few questions to check for understanding.

Learn about water channels called aquaporins that allow water to cross the cell membrane.

Describes the bond angle of the water molecule during the transition from liquid to gas state. Also provides several examples and explanations for responses and answers given.

Use this resource to learn about the three different phases of water; solid, liquid, and gas. What happens to water as it changes into a solid or gas? Includes short and easy to do activity.

Advanced chapter of the book "The Molecular Biology of the Cell" describes and provides illustrations of our most current understanding of the chemical makeup of cells and their components. Explains in detail how electron activity keeps...

Capillary action is described. Examples are illustrated. Links to related topics.

This site provides a basic definition of reverse osmosis, with a bit of a slant on why water pretreatment is important.

Capillary is described and explained. It is related to surface tension. Examples in botany and human physiology are given.

Brief text summary of what students learn in the Diffusion across a Selectively Permeable Membrane lab, along with links to download Student Handouts and Teacher Preparation Notes in PDF or Word formats. Main teaching points include...

This site gives a good explanation of osmosis and reverse osmosis. Also includes a scientific diagram of the process.
