Learners explore the effects that extreme temperatures have on the material properties of solids. They investigate the properties of a material whose state depends on extreme temperatures and witness how it interacts with room...

Learners explore the six phase transitions between gases, liquids and solids for a variety of elements. Each group of students focuses on a different element, investigating its physical properties during each of the six phase transitions.

Student teams use a digital camcorder and iMovie to create a commercial about an element. They also use the Internet and their textbook to gather the following information about their element: the name, the symbol, the atomic number, the...

Students place themselves in the position of a water molecule, ice molecule, or steam molecule and then describe the process of changing phase.

Students develop procedures to explore the behavior of fish.  In this scientific experiment lesson students from a hypothesis, write a question, identify different variables and controls in their experiment. 

Students examine molecules and the changes in energy of a system.  For this energy systems lesson students complete a lab activity and describe changes of state.

Learners explore the concept of sea ice. In this sea ice lesson, students interview arctic hunters to regarding the sea ice safety and attributes.

In this combined gas law activity, high schoolers use the relationship between temperature, pressure and volume to complete a table using the combined gas law. They find volumes, pressure and temperature of substances given two of the...

Ninth graders discover the reasoning behind spraying water on fruit and seedlings in preparation for hard freezes. In this conceptual physics lesson, 9th graders conduct an experiment to measure the heat released when water goes from a...

In this gas laws activity, students solve eleven problems using the various gas laws to find temperature, pressure, and volume of gases.

In this Kelvin scale worksheet, students read about the relationship between the Celsius scale and the Kelvin scale. They are given the equations to convert from one scale to the other. They find the equivalents for temperatures measured...

Students explore objects before and after heating using their senses.  In this matter and energy lesson, students experiment with a variety of objects and use their senses (except taste) to make predictions and record observations...

Students define temperature and heat, distinguish between temperature and heat flow, calculate amount of heat energy released or absorbed in chemical process, and design procedure, through experimentation, to gather and evaluate data to...

The learners construct a heating curve and explain its components. They perform calculations. They review phase changes and quantify Energy differences. They review phases of matter and their energy content.

In this mixtures worksheet, high schoolers read about mixture and what determines if a solute dissolves in a solvent. They answer three questions about solutions and determine from a list of compounds which are soluble in water.

For this chemistry worksheet, students calculate the freezing point of a given solution. Students calculate the final temperature and state of the water in a given problem. Students solve several problems provided.

Learners work in teams of four as they conduct four controlled Jell-O experiments over a two-day period. The Family Page extends this learning to the community by providing families with challenges to explore at home.

Wow! Expose your chemistry class to every method of separating mixtures by showing this slide show. Learners will view diagrams and graphic organizers that support notes about filtration, chromatography, distillation, centrifugation, and...

For this mixtures worksheet, students fill in 7 blanks, determine if 4 statements are true or false, match 7 terms with the appropriate definitions, and solve 2 problems. These include topics such as homogeneous and heterogeneous...

Students explore human growth and development as they participate in class activities, reading and discussion. Worksheet and handouts are included in the lesson.

Students identify fossils. They identify evidence of change over time when given pictures of fossils to determine the proper sequencing. In addition, they determine evolutionary relationships by comparing embryonic structures.

In this solids, liquids and gases learning exercise, learners observe a teacher demonstration about gases and they experiment with liquids to show diffusion, shape and volume. They answer nine questions about the experiments related to...
