What common chemical includes safety warnings for being harmful if swallowed or inhaled, causes serious eye damage, and needs to be cleaned up immediately if spilled on the floor? Surprisingly, the dangerous chemical turns out to be...

What makes air fresh or not so fresh? The solution is solution chemistry! Explore homogeneous mixtures with a video from the JFR Science series. The narrator explains a variety of solution terms, how to classify solutions, and how people...

Tiny particles can provide big learning opportunities! Middle school scientists explore the world of nanoparticles through reading, discussion, and experiment. Collaborative groups first apply nanotechnology to determine water hardness....

How and why barium is used in X-rays is the focus of a video that also describes the similarities with bones, the insolubility, and the medical applications of this element.

Classes explore colloids through readings and questions in lesson 10 in a series of 36. They learn everything from methods of preparation and properties to how to classify colloids. They finish the lesson by seeing how to apply...

Examine the properties of colloids and suspensions. A slide show defines each mixture and explains their properties. Pupils learn to identify each mixture and compare them to solutions. 

Bridges rely on tension and compression to keep them standing. Pairs test this principle by constructing simple bridges and applying a force to the center. Teams use the provided worksheet to record their observations of the reaction of...

Explain how to find the center of mass of an object. A video uses suspension and plumb lines to find the point of intersection that is the center of mass. It also relates this concept to simple pendulums, covering the time period and...

Super scientists visit ten stations to predict, observe, and draw conclusions about the physical and chemical changes that occur when different states of matter—liquid, solid, and gas—are placed under a variety of conditions. To...

Young scientists investigate chemical and physical changes to the states of matter—gas, liquid, and solid—as well as solutions and suspensions with a variety of demonstrations, grand conversation, and an interactive quiz to check for...

Chemists are frequently in suspension, but not because they misbehave! Scholars mix various items with water to create solutions, suspensions, and colloids. They test each one to determine their differences and properties. The resource...

My name is Bond, Hydrogen Bond. Written for distance scholars working on chemistry at the high school level, the lesson includes eight weeks worth of material divided into six parts: substances you use, mixing it up, your skin, what's...

Here is a different approach to solutions: a worksheet that has chemistry learners use words to describe them! This is an outstanding exercise that will stretch learners to show what they know. They answer questions comparing solutions,...

Students research bridges from around the world looking for the Parisian architecture. They identify arch, suspension, cable and covered bridges. They draw half a bridge utilizing Crayola Erasable Markers. They construct their bridge...

If you are not part of the solution, then you are part of the precipitate. The presentation covers solutions, suspensions, solubility, dissociation, and acid/base reactions. This is the 19th lesson in a series of 26.

Middle school scientists compare and contrast heterogeneous and homogeneous mixtures. They differentiate solutions, colloids, and suspensions by examining samples of each. Note that the bulk of the lesson plan directs you how to...

A simple introduction to solutions, colloids, and suspensions is available in the first few slides. Most of the remaining slides are dedicated to osmosis. While the slides themselves are organized and educational, the topics of solutions...

Students find a way to mix oil and water. In this emulsion activity, students attempt to mix oil and water, then add egg yolk to the mixture to serve as an emulsifier and observe the results.

In this solutions, suspension and colloid worksheet, students complete a lab experiment in order to determine if a given mixture is a solution, suspension or colloid. They are given six vials and they record their observations of each...

Students study the basic artistic styles of suspension bridges. They follow step-by-step instructions to draw a suspension bridge. Students discover volcabulary related to the architecture of bridges. They examine websites of bridges.
