In this moon phase worksheet, students are given a "moon pop" and they make a diagram of the moon's phases using the "moon pop" as a guide. They answer questions about the phases of the moon and solar and lunar eclipses.

Students answer the question, "How are the motions of the Earth, the moon, and the sun, related to the moon's phases?" They observe the moon to create a moon journal and a phases of the moon diagram.

In this heat transfer and phase change worksheet, students experiment with ice, salt, and milk to show the relationship between the temperature of a solution and its phase. Students turn milk from a liquid to a solid and graph the...

Students make observations of ice as it melts. In this phase change lesson, students observe ice as it melts in a cup. They discuss their observations and place the cup of water into a freezer to change it back into ice.

Sixty multiple-choice chemistry questions make up this comprehensive exam used for the 2001 US National Chemistry Olympiad. Every topic that you would expect to approach in a general chemistry class is queried on. You could easily use...

Here is a copy of a past national challenge exam that you can use in your general chemistry course as a unit or semester review. Sixty multiple-choice questions query learners on properties of matter, stoichiometry, reactions, and...

Characteristics of each state of matter are listed, the formulas for heating water are detailed, and values for boiling and heat of vaporization are presented. This simple slide show provides direct instruction as well as practice...

Your physical science class learns that there are three states of matter, and that adding or removing heat can cause it to change from one state to another. By the animations, printed information, and discussion between RJ and Zoe, they...

If the area you live in is arid, or the preceding experiment in this unit didn't yield obvious results, use this one in place of it to help reveal where condensation comes from. The mini unit that this is part of a comprehensive...

As a stand-alone or as part of the intended unit, this is a valid investigation of what causes condensation to occur.  By limiting the amount of air around a cold cup of water and comparing it to one out in the open, they find that...

The University of the State of New York has designed a series of exams for high schoolers. This chemistry exam is one of the most comprehensive and well-written that you will ever find. It consists of 84 questions in a variety of styles,...

The 2006 version of the Regents High School Exam is just as thorough as the rest of them! Assess chemistry learners on the entire year's curriculum when they take this 13-page test.

For this thermodynamics worksheet, students describe the reactions given and then determine the thermodynamic calculations. This worksheet has 14 problems to solve.

Watch an entire month flash before your eyes with this fun phases-of-the-moon flip book activity.

Consider our energy sources: wood, coal, oil, uranium. Learners compare the pollution to energy produced for each. They practice fractional distillation of an alcohol/water mixture to simulate the process of refining crude oil....

Junior chemists manufacture biodiesel in the lab. In this exercise, they check the purity of the biodiesel using thin layer chromatography. They also calculate its density and heat of combustion. They are sure to rise to the...

Examine the unique graphs coined broken-line graphs. Using the phase change of water for data, learners answer questions related to the temperature and energy at different times in the cycle of the phase change. Questions focus on the...

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,...

There's more to melting than meets the eye! Junior physical chemists investigate the differences between specific and latent heats as a substance undergoes a phase change. Users remove heat from the system and observe changes in kinetic...

Students explore the states of matter. They discuss the different phrases of matter and categorize everyday substances as solids, liquids, or gases. Students explore the relationship between the phases on an atomic level and the role of...

Students learn about the phases of the moon. In this moon phases lesson plan, students learn about what causes the moon to look different to us everyday and how the Earth and Sun's position determine what phase the moon is in.

Kids are fascinated by the moon for good reason! Here's a great resource to help them chart the lunar cycle for a month, referencing high-detail photographs and an informative chart as they complete their own calendar.

For this chemical phases diagram worksheet, students use a diagram to answer 6 questions about the three different phases-solids, liquids and gases. The diagram is of a mystery compound referred to as "X".

In this Bill Nye packet, 5th graders focus on the phases of matter.  Students complete a chart of what is already known and what has been learned as well as 6 short answer, 7 true/false, and 3 multiplie choice questions about the...
