Students work together to observe the bond lengths of single, double and triple bonds. They make their own predictions about the strength of the bonds and chemical reactions. They answer discussion questions to complete the...

Young scholars examine the rule of "like dissolves like." They define and describe solutions and solubility models on molecular liquids, ionic solids, and molecular solids.

In this Chemistry 1A worksheet, learners review, molecular weight, solubility, endothermic reactions, and number of protons, neutrons, and electrons for elements. Students review Lewis Structures and how to predict the amount of product...

Students compare their unknown serum against a set of known serum standards and determine the animal source of their serum. They write a lab report to communicate their results.

Students examine how to represent organic compounds three-dimensionally. They write a synthesis reaction for three demonstrations, and construct a three-dimensional structure using a molecular modeling set.

In this compounds activity, students identify the main intermolecular force in the given compounds and explain the differences between dipole-dipole forces and hydrogen bonds. This activity has 5 short answer questions.

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...

Students explore the strength of intermolecular attractions. They make slime and compare the difference in the physical properties of sheet and powdered polyvinyl alcohol with polyvinyl acetate.

Several slides compare different temperature scales. Thermal expansion, heat transfer, and Maxwell speed distribution are also explored. The last two slides seem unrelated to the topic of heat, but are easily left out of this otherwise...

Young scholars investigate how water passes through cell membranes. In this biology instructional activity, students differentiate osmosis and diffusion. They illustrate the movement of water in both processes.

Students create a polymer out of glue, water, and borax. They discuss the resulting substance and perform several experiments with it.

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.

Learners practice writing research proposals to test the color fastness of a dye once it has been exposed to a t-shirt. Each proposal needs details of experimental design, length of treatment, and means of cleaning the shirt. All...

Young scholars compare and contrast photosynthesis and chemosynthesis as processes that provide energy to biological communities. They investigate the energy content of hydrocarbons used in coral communities.

This PowerPoint progresses slide-by-slide through all the facts you would want to deliver about acids, alkalis, salts, and the related lab tests. Each slide has one or two facts about a physical or chemical property or behavior. The...

Students investigate the concept of molecular structure. They describe the behavior of simulated molecules and identify any dislocations in crystalline structures. They also define various related vocabulary words and use them in...

In this relationships and biodiversity worksheet, students investigate the relationships between 4 plants sample using 7 different tests. These include looking at structural characteristics of the plants, seeds and stems, using paper...

Students apply the principles of chemistry to investigate the concept of how a hydrogen powered car works. They study the electrochemical reactions that provide the energy source. Students also record observations in the functioning of a...

High schoolers examine the characteristics and makeup of glass. In groups, they research the life and work of Dale Chihuly and how he used glass to create his artwork. They answer discussion questions on different pieces of art and share...

In this cells worksheet, students will review cell characteristics and structure and different types of cells and what role they play in the body. Students will investigate experimental results of the influence of sucrose on the...

Students examine how some natural substances are polymers.  For this polymer lesson students complete a lab and give examples of a physical change. 

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.

In this literacy worksheet, learners find the words that are in the word search puzzle that focus upon the vocabulary that is from the theme of the sheet.

Students conduct a series of activity that demonstrates Charles' and Boyle's Law. In this chemistry lesson, students determine the relationship among pressure, volume and temperature. They solve problems using mathematical equation.
