Entropy, it isn't what it used to be. Presentation includes kinetic-molecular theory, heat and internal energy, thermal equilibrium, temperature scales, laws of thermodynamics, entropy, latent heat of fusion, specific heat, calorimetry,...

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...

What's the matter? Gas, solid, liquid, or plasma. The presentation covers how to describe and identify matter, changes in matter, types of matter, measuring matter, particles of matter, Democritus, and John Dalton's Atomic Theory.

Litmus paper, why so blue? A chemistry lesson includes a pre-lab activity, practice calculating pH, an experiment measuring the pH in acids and bases, a titration demonstration, and a titration experiment. 

In this gases activity, students review the kinetic molecular theory and use the ideal gas law to solve 20 problems.

For this atomic theory worksheet, learners review the observations that led to the conclusion of the atom having a positively charged nucleus. Students compare atomic number and mass number and explain how the discovery of subatomic...

In this reaction kinetics worksheet, students draw a graph of energy vs. reaction progress and determine the factors which change the speed of a reaction. Students learn about rate laws. This worksheet has 1 graph, 15 fill in the blanks,...

Mostly what you will find here is a history of quantum mechanics. Influential scientists are introduced (along with some of their recorded quotes), the progression of atomic models is reviewed, and finally experssions and equations are...

This wonderful recap of powerful figures in scientific history includes pictures, important dates, and the information about their inventions or impact. Atomic structure and the photoelectric effect are introduced. The first slide gives...

In this physics worksheet, students examine the theory of quantum mechanics through the answering of the nine questions. The answers are accessed through the links by each question.

In this solutions worksheet, students determine colligative properties, calculate specific heat, and review the kinetic theory as it applies to gases. This worksheet has 8 multiple choice and 9 problems to solve.

Does the early bird really get the worm? If so, which color of worm does it prefer? In an exciting and easy week-long field investigation, young field biologists set up a one square meter feeding area for birds. If you have a webcam,...

Outer space may be a lot closer than you think! Science scholars model the layers of the atmosphere using transparencies to gain insight into the scale of space. The resource includes ideas to tailor the activity to the skill level of...

Twelfth graders create an artistic version of a Vetruvian teen. In this anatomy lesson, 12th graders design an experiment to test the theory of the ideally proportioned man. They present their findings in class.

Pupils encounter the complexity of identifying the cause of unusual variations in WOW conductivity data. They propose theories on why there was a sudden increase in conductivity in Ice Lake, Minnesota during July of 1998.
