In this molecular model worksheet, students use a molecular model kit to construct 13 different molecule models. After constructing the molecules, the students complete 32 short answer questions.

Did you know that if you wait long enough, the M on the outside of an M and M will float to the surface when submerged in water? Learners observe the sugar coating of an M and M while it is dissolving in water. They explain how this...

Micelles consist of an aggregate of molecules in a colloidal solution. The simulation presents two different ways the molecules assemble into micelles based on the polarity of the solution in which they are placed. Scholars can set the...

In this moon worksheet, students read about the data collected from the Deep Impact/EPOXI and Cassini missions to the moon that have detected the presence of hydroxyl molecules under the moon's polar craters. Students solve 4 problems...

Students investigate adhesion, cohesion and surface tension. In this molecular forces lesson plan, students observe multiple demonstrations that show surface tension, the attraction of water molecules to each other and the ability of...

Do polar opposites attract? After an introduction on the polarity of molecules, pupils are asked to design a self-assembling model using materials with different polarity. The challenge should motivate learners to develop a workable...

A full-fledged practice final prepares pupils for their general chemistry final exam. If they complete these 57 multiple-choice questions correctly, they will be well-prepared. Note: even though the questions are multiple-choice, there...

In this water and solvent worksheet, students answer 20 questions about solutes, solvents, polarity in molecules, and the characteristics of water as a solvent. Students answer 3 questions about the lab they completed using temperature...

In this water worksheet, students read about hydrogen bonds in water and the differences in electronegativity between the oxygen atom and the two hydrogen atoms in water. Students answer four questions about the structure of water and...

In this organic molecules worksheet, students solve nine problems involving reactions of organic molecules. They must draw and label reactions, explain the processes of the reactions and predict products of reactions

High schoolers experiment with water as a component of suspensions, solutions, and heat conduction contributing to the use of food and the health and wellness of human beings.

In this water worksheet, students explore the reasons why water is considered a universal solvent. Students compare different ways to change the dissolving rate of a solute. This worksheet has 11 fill in the blank and 8 matching questions.

Young scholars explore the unique behaviors of water. They investigate surface tension using water drops on a penny and pennies dropped in a cup.

Ninth graders examine the electrolysis of water by completing an experiment.  For this water lesson students will explain how hydrogen can be extracted from water and how energy flows through an electrolysis system. 

In this solutions worksheet, students review the properties of solutions, the polarity of molecules, molarity, and solubility curves. This worksheet has 8 short answer questions and 15 problems to solve.

Middle schoolers observe how salinity affects the time it takes water to freeze. They participate in an experiment to determine that ice is essentially salt-free whether formed from fresh or salt water

In 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...

Students complete lab activities to investigate the "sticky" properties of water, such as surface tension and capillary action, due to the polarity of the molecules.

In this covalent compounds worksheet, students name 6 compounds given their chemical formulas, they write the formulas for 6 compounds given their chemical names and they answer questions about boiling points and solubility. They write...

Explain the properties of water. Identify the properties of water that make it a polar molecule Describe hydrogen bonds and how they differ from covalent bonds Discuss the differences between hard water and soft water Compare the heat of...

In this water and diffusion worksheet, high schoolers will explore the characteristics of water and the water molecule. Students will also answer questions about diffusion and the movement of materials due to concentration differences....

Can scientists sort molecules based on their interaction with oil and water? The simulation demonstrates how this is possible. Pupils decide when to insert a molecule and observe how they sort themselves based on polarity.

Students estimate the size of a molecule of oleic acid. They conduct an experiment using chalk dust, water, and oleic acid, solve various calculations, and answer discussion questions.

In this solvent activity, students explore why water is considered a universal solvent. Students explore what can change dissolving rates. This activity has 8 matching, 3 short answer, 11 fill in the blank, and 4 problems to solve.
