Students analyze the level of acid and base in a titration. In this chemistry lesson, students investigate the amount of acid and base required to create certain household chemicals. They perform this activity without the use of burets.

Students determine the best solvent system for separating a methylene blue/sodium fluorescein mixture by thin layer chromatography. They conduct an initial TLC separation using ethanol and a different solvent mixture and analyze the data...

Students explore how an oil spill is contained and cleaned up. They investigate an oil absorbing polymer that is hydrophobic, absorbs up to 19 times its own weight in nonpolar liquids, floats on water, and can be reused or disposed of by...

Students extract DNA from their own hair roots. They run an electrophoresis gel to examine patterns of their DNA along with standard DNA. The experiment is based on a crime scene scenario.

Students investigate hot melt glue using a hot melt glue gun as an an injection molding simulator and a melt index viscometer. They evaluate the effect of heating and cooling by weighing the glue extruded over a constant time period.

Learners illustrate the changes in the properties of a material at its glass transition point. They gather data which they use to construct graphs regarding elastic modules versus absorption modulus, tangent delta, and the effect of...

In this science worksheet, students examine the graph with elements in order to differentiate atomic mass and categorizing the content.

In a simulated crime science investigation, chemistry or physics sleuths use spectroscopy to analyze solutions. The lesson gives learners practice making salicylate solutions, using spectrophotometers, calculating dilution amounts,...

A scenario is presented for chemistry techs to address. Using titration techniques, they must analyze hydrogen peroxide solution samples. They evaluate accuracy and precision in the process. They also gain experience consulting the MSDS...

Two scenarios are presented for chemistry detectives to decipher. Both require the use of an infrared spectrometer and focus on the examination of polymer materials. In the first, lumps in polyethylene bottles are analyzed. In the...

In this chemistry worksheet, students use the periodic table of elements in order to identify the common elements. The detail is very detailed.

Experiment with chocolate coating on cookies! What a delightful way to learn about food processing and chemical engineering. Throughout this activity, groups collect measurements and make calculations. They conclude by writing...

The video clip that comprises the warm up is not available, but the related article from The New York Times and the movie trailer for Aliens of the Deep are, leaving enough material to make this a fascinating lesson on deep-sea...

Though the publisher designated this unit for use with third through eighth grades, this particular lesson plan would be best used with middle schoolers due to the specific measurement skills required. Basically, they set up the reaction...

Students are challenged to investigate the physical and chemical properties of plastics and use them to design a system that could be used to separate them. 1st year chemistry students use density for separation, students gathered...

Students are introduced to colorimeter on two levels. They investigate how to physically manipulate the colorimeters. Secondly, the students start on a pathway of discovery to one of the most important principles in analytical chemistry:...

Advanced chemistry classes compare the polymerization of styrene using two different initators: benzoyl peroxide and aluminum chloride. Once they synthesize polystyrene, they compare the two producet for melting point and density. There...

Divide your chemistry or environmental science class into two groups. Each group tests water samples from a river for the concentration of phosphorus using a different method. With chemists, you can use this activity as they learn to use...

Advanced chemistry scholars read about gas chromatography as a means of separating mixtures into their components. Then they try the technique on fingernail polish remover. Detailed instructions are provided via a lab sheet for your...

Clever! Use a clip from the 1997 film, Volcano, to get your chemistry class knee-deep in heat concepts related to lava. In the movie scene, lava flow is stopped in the nick of time. Your class must use calculations to determine if this...

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,...

Although there are only six questions on this chemistry handout, it makes a thorough review of solutions. Novices explain why a compound is not an electrolyte, identify types of compounds, and calculate moles, grams, and molalilties in...

Lewis acids and bases, Brønsted-Lowry acids and bases, ionization, and more are covered by this chemistry handout. It serves as a review of a specific textbook section, but will also serve as a nice review for any general chemistry...

Here is a short, but well-rounded review of redox reactions. Chemistry apprentices identify the type of reaction, write half-reaction equations, balance equations, and assign oxidation numbers. Being brief, this would make a purposeful...
