In this chemical compounds worksheet, learners complete a graphic organizer by determining the electron dot formula, molecular shape, bond angle, bond polarity, and molecular polarity for 7 given compounds.

In this chemistry worksheet, students respond to several multiple choice questions relating to bonding and acid-bases. They also identify the various types of bases and how they differ from each other.

In this molecules worksheet, students answer post lab questions about types of bonds, factors that determine polarity and molecular geometry. They calculate electronegativity differences in atoms and determine the types of bonds between...

Students investigate the properties of matter. In this properties of matter lesson, students observe containers of different metals and discuss their properties including density. Students find the density of an unknown metal and of...

How can you effectively provide detailed concepts of water properties to your high school class in a way they find exciting and challenging at the same time? By letting them play, of course! Through a variety of...

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...

Without water there would be no life on this planet. Biology learners find out why by reading this handout. Create a worksheet of questions to answer after the reading. Follow it up with quick demonstrations or laboratory activities that...

Students separate a mixture of pigments with ion exchange chromatography and predict whether the ion-exchange matrix is positively or negatively charged based on the type of pigment bonded to the matrix.

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...

Alia-Seltzer tablets cause a very obvious chemical change, but do they also cause a temperature change? Each class member explores hot/cold packs, discussing how these temperature changes occur. Groups then design and carry out their own...

Learners practice drawing Lewis dot structures, build molecules with model kits, and predict molecular shapes using VSEPR theory. The combination of written work and hands-on reinforcement benefits young scientists.

Lost an electron? You should keep an ion them. Young chemists learn qualitative analysis in the second lesson plan of an 11-part chemistry series. After observing reactions of simple salts, the teacher provides pupils with unknown...

Individuals explore solubility by modeling how water dissolves salts. They then view a video and compare how well water and alcohol dissolve salts, relating their comparisons to the structure of each molecule. 

High schoolers investigate stereoisomers using models that can be rotated and manipulated. In this stereoisomers lesson plan, students try to make models of molecules look alike by rotating the bonds. Using a mirror, the teacher...

Water is crucial to survival. Scholars gain an appreciation for water by reading about it, learning about its atomic properties, and investigating its properties through six stations in a lab activity.

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...

Students investigate the properties of water. In this chemistry of water lesson plan, students observe a demonstration of the properties of water using sand, sugar, oil, vinegar and salad dressing. Students experiment with water, pepper,...

Students work together to explain the VSEPR theory and how it relates to molecules. They name electron pairs that can surround the central atom of an organism. They discuss the factors that determine the polarity of a molecule as well.

Students predict the shape of molecules using VSEPR theory. In this chemistry lesson, students differentiate a polar and nonpolar molecule. They discuss why water's polarity is very important.

For this solubility worksheet, pupils identify substances as either ionic or molecular, define saturated solution and solubility, and calculate concentration of solutions. This worksheet has 7 short answer, 5 fill in the blank, and 27...

In this chemistry worksheet, students fill in the chart for question one. The chart is filled out examining the mass, protons, electrons, and neutrons for specific atoms.

This is not they typical set of teacher instructions. It is an organized chart of the important organic compounds. For each, the involved elements, the name of the building block monomers, the names of polymers, extra information, and a...

Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...

A great way to learn about molecular structures is to make a model. Gumdrops and toothpicks are used to construct crystal models. The models are based on theories of crystal shapes that occur because of positive and or negatively charged...
