In these creative hands-on activities, students construct several different molecular models that represent substances that play an essential role in our nutritional needs. Using gum drops and toothpicks, students design the models....

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...

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

In this chemistry worksheet, students draw the Lewis structures of 9 compounds and polyatomic ions, identify their molecular shapes and polarity.

Framed as an organic chemistry practice test, this resource could be used for a variety of purposes. Composed of 15 questions about organic compounds such as isomers, alkynes, alkenes and amines, and other topics related to organic...

In this elements worksheet, high schoolers compare and contrast the characteristics of metals and non-metals. Students practice drawing Lewis dot diagrams and writing ion notation. This worksheet has 9 word problems, 8 matching...

High schoolers engage in a lesson which includes flame tests and the construction of a simple diffraction spectrograph with which to measure sodium ion emissions. They use the Bragg equation to compute the wavelength of the line spectra...

Young scholars study the effects of water, salt water and heat on common household materials. They separate an emulsion and show that the materials are completely recoverable and observe the effect of acetone and water on polystyrene.

Learners divide substances into categories: made of chemicals/not made of chemicals, synthetic/naturally occurring, and toxic/nontoxic. They observe a mystery chemical and determine what precautions they need to take when handling an...
