This lab activity is geared toward experienced chemistry learners, in particular, those who are familiar with organic chemistry. They will create a synthetic elastomer  and then make observations and measurements of its different...

As to be expected from the American Chemical Society Olympiad Examinations Task Force, this 60-question test tops the charts in terms of excellence. It consists entirely of multiple choice questions designed to assess a year's worth of...

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...

There's no need to water down the resource. A tutorial takes learners through the process of creating dilutions for any solution. Specifically, it focuses on serial dilutions with successive factors of 10.

Young scientists demonstrate their understanding of cell transport on this comprehensive worksheet. Focusing on cellular structure and the different processes that allow materials to move into, out of, and throughout animal...

Take your biology class on an exploration of the inner workings of cells with this multimedia presentation. Looking closely at the structure of cell membranes and the processes of osmosis and diffusion, this resource explains for...

Beginning biologists place a drop of food coloring into water of differing temperatures to observe the effect on the diffusion rate. They remove the shells from raw eggs and then experiment with osmosis over the remaining membranes....

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...

A neat presentation and challenging content make this solutions worksheet an ideal homework assignment for your budding chemists. Short answer and problem solving questions get them to review molarity, products, and reactants.

In this solutions worksheet, learners identify solutes and solvents from a list of solutions and they draw water molecules bonding to each other. They fill in the blanks with terms related to bonding in solutions, density of solutions...

What a great way to explore the scientific process! Learners conduct an experiment in which they use sugar and water to illustrate the concept of solutes and solvents. With this hands on approach, they are bound to remember what they...

The first two pages of this resource may not be useful as they contain a narrative as to how someone can improve their grade on an organic chemistry exam. The final page, however, contains four sample MCAT exam questions. You could use...

Fifth graders design an experiment in which they separate mixtures. In this mixtures lesson plan, 5th graders define mixtures, solutions, solutes, and solvents. They watch a video, complete worksheets, and perform an experiment to...

In this solubility activity, learners use a solubility curve to determine is different solutions are saturated or not. This activity has 19 problems to solve and 2 short answer questions.

In this solutions worksheet, students complete a three step procedure and record the dissolving time of candy. Using their data they create a graph and answer 4 analysis questions.

In this solutions worksheet, students calculate molality and mole fraction. Students define colligative property and determine what affects the solubility of gas in solvents. This worksheet has 2 short answer questions and 9 problems to...

In this water worksheet, students review the properties of water including the density, boiling point, and evaporation. Students define mixture, solute, and solvent. This worksheet has 22 short answer questions.

In this solutions worksheet, students brainstorm different types of solutions and an example of each type of solution. This worksheet is a graphic organizer.

Students elicit data on the water cycle, ocean topography, and island formation in this six lesson unit. The ocean floor and the properties of water are examined through a variety of discussions and hands-on experiments.

Young scholars hypothesize about the amount of carbon dioxide in soda bottles. In this chemistry lesson, students design an experiment to solve the problem. They share findings in class.

In this solutions activity, students define solute and solvent. Students calculate the concentration of solutions. This activity has 4 short answer questions and 4 problems to solve.
