Lab groups fill a section of dialysis tubing with glucose and starch solutions and suspend it in a water bath. They use iodine as a starch indicator and a glucose test strip to find out if either of the materials crossed the selectively...

Problems come in all shapes and sizes, but the first step in solving a problem is to identify just what the problem is. Through a series of games and activities, middle schoolers learn first to identify a problem, decide on a solution,...

Middle schoolers apply all they have learned in the Problem Solving module by participating in a contest to see which group can build the tallest tower using only sheets of paper and masking tape.

"What should I do?" "How should I do it?" Middle Schoolers learn that answering these two questions is the key to solving problems. They begin with the first two steps of the Decision Making Process (gathering information and identifying...

How do people determine if something is acidic or basic? Learners make their own acid-base indicators using red cabbage and then determine the acidity and alkalinity of different substances. First, they test substances of known pH and...

Root for young mathematicians learning about functions. A set of two problems assesses understanding of polynomial functions and their roots. Scholars select values for a, b, and c, and then create two functions that meet given...

Does the accuracy of the first guess make a difference down the line? Learners investigate the effects of the iterative process of finding roots, using Newton's Method. By moving the initial guess of a root on a graph, pupils observe the...

Does the value exist? The interactive allows pupils to visualize the Intermediate Value Theorem. Using the visualization, individuals respond to questions using specific values and general values. The class comes to the conclusion what...

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...

The brother-sister pair Carlos and Clarita need your class's help in developing their new pet sitting business. Through a variety of scenarios and concerns presented to the siblings, the learners thoroughly explore systems of equations...

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...

For this solutions, suspensions and colloids worksheet, students use diagrams to show how particles are different in each of these mixtures. They also distinguish between characteristics of each of these types of mixtures and categorize...

In this solutions worksheet, students answer questions about the solubility of various substances in solvents such as oil in water and nitrogen gas in helium. They draw water molecules to show bonding between them and they diagram a...

In this solutions worksheet, students 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...

Future chemists practice laboratory techniques by creating a monochloramine solution. The objectives are to use of dilution, 9concentration, and measurement skills and to prepare a solution that will be used in a water treatment...

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...

Through grand conversation, help scholars identify issues that harm the Earth and find solutions on how to solve them. After voting—on what your class deems the most important problem—stretch writing muscles with a problem-solution...

Little chemists address whether or not you can get sugar back out of tea after it has dissolved. The PowerPoint itself simply walks them through the questioning process, considering different possibilities. The final slide settles on...

Chemistry apprentices unscramble seventeen general chemistry terms. At the bottom of the list, you will find online access to the solution. Print this resource out and have learners also write definitions for the different vocabulary...

Salts, solvents and hydroxides are listed and pupils will need to add information about a selection of electrolytes.  For a list of compounds, they indicate whether the solute particles will be ions or molecules and then the symbols...

In this transition metal worksheet, high schoolers are given equations of transition metals and their ions. Each equation shows the changes in colors of the ions when heat, salt or other substances are added to the metals.

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

Young scholars participate in a hands on activity simulating an oil spill. In this oil spill lesson plan, students conduct an experiment about an oil spill, discuss how it would affect the environment and provide solutions to prevent oil...

Students investigate common household items and classify them into types of matter. In this matter instructional activity, students group given items into categories based on their characteristics. They also complete a concept map about...
