Students learn the procedure for mixing secondary colors from primary pigments and observe the results of mixing two primary colors.

Ninth graders identify the different parts of a wave. In this physics lesson, 9th graders observe wave behavior as it travels through a boundary. They determine the relationship between wavelength, frequency and velocity.

Students explore Faraday's Law. In this electromagnetism lesson, students investigate Michael Faraday. Students discover the history of the electromagnet. Students examine the parts of an electromagnet.

Pupils play a "Biochemistry Taboo" game using their knowledge of Biological chemistry and taboo cards. This lesson can be used as a review or an introduction into concepts covered in Biochemistry and includes a pre-activity worksheet.

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

Learners investigate the integrity and strength of different types of food wraps. They test the wraps and create a graphic organizer for the data. Once it is organized then a lab report can be written. The instructional activity contains...

Students calculate the concentration of different solutions. In this chemistry lesson, students explain what a solution is. They explain ways to change the concentration of a solution.

Sixth graders explore ways to analyze the properties of water and examine the chemistry of water.  In this water lesson students work in groups and complete several activities. 

Students explain the importance of the five main biogeochemical cycles. In this chemistry lesson, students discuss how ions are transported in the environment. They design an experiment to collect data on eutrophication.

In this intermolecular forces worksheet, students answer 4 questions about the forces between atoms within molecules and compounds. Students rank the boiling points of compounds based on their intermolecular forces and they explain...

In this chemicals worksheet, high schoolers answer 15 multiple choice questions about chemicals, compounds, inorganic and organic molecules.

After a short introduction, chemistry aces get right into drawing electron dot diagrams for covalent bonds. There are only three questions to answer, so this is not a comprehensive worksheet. It can be used when introducing your class to...

In this crystals worksheet, students complete a graphic organizer by filling in the characteristics of the different crystal types including melting/boiling point and electrical conductivity.

In this compounds worksheet, students draw the Lewis dot structure for given compounds plus determine the electron geometry, type of hybrid, molecular geometry, polarity, and number of sigma and pi bonds. This worksheet has 5 fill in the...

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 explore visosity of matter. They run tests of various liquid substances to observe and compare rates of flow of different substances. In addition, they relate viscosity to distance travelled by sample substances.

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.

Using yarn and chenille stems, lab groups collaborate to model mitosis and meiosis. Brief background information and a vaguely written procedure comprise this outline. More instruction needs to be provided to learners about cell division...

Students determine that some liquids are able to evaporate more readily than others. They create a balance using cups and a ruler to determine which end of a strip dipped in alcohol or water evaporates the fastest, hence loses the most...

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

Students conduct a lab to determine the best way to separate a variety of mixtures choosing between paper, thin layer and column chromatography. They use chromatography techniques to identify unknown substances and submit a lab report on...

In this solubility worksheet, students 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 acids and bases worksheet, students read about the differences between acids and bases and then complete a table comparing the characteristics of both. Then students determine if the given statements describe an acid, base, or...

In this chemical compounds worksheet, students write the name of compounds from their chemical formula, balance equations, write electronic configurations for elements, and draw Lewis dot structures. This worksheet has 8 fill in the...
