A thorough investigation of cell transport is provided when completing the assignment. The first half requires biology class members to answer questions about diffusion and osmosis with the aid of diagrams. Then they fashion an...

Anyone that lives around snow knows that adding salts to water increases its melting point. Are there solutes that affect the boiling point as well? A scientific experiment has learners add different solutes to water and then...

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.

How do you engage pupils in a discussion about osmosis without leaving them overwhelmed? By providing them with the tools to perform an exciting experiment, and they will see osmosis in action! Young chemists and biologists use...

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

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....

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, 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...

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...

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...

In this solubility worksheet, students use a solubility curve to determine is different solutions are saturated or not. This worksheet 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 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 hypothesize about the amount of carbon dioxide in soda bottles. For this chemistry lesson, students design an experiment to solve the problem. They share findings in class.

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