Moving from its definition to how it moves and its different types, scholars see different examples and then move into its application and use in everyday lives, in an energy-based presentation.   

During a macromolecule lab, young chemists perform multiple tests, including iodine starch tests, to determine if eight mystery foods contain lipids, sugars, or starches.

In this chemistry worksheet, learners investigate through experimentation the solidifying behavior of some edible fat mixtures by determining their cooling curves. Then they data-log equipment to obtain a large number of temperature...

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 are introduced to the laws of thermodynamics. The 1st law of thermodynamics states that the energy must be conserved when two objects of different temperatures come in contact. If one object gains energy, the other object must...

Eighth graders explore the chemical and physical properties of a variety of elements in a lab setting. They organize the data they collect onto a spreadsheet and then choose one element from the periodic table to research. They...

Students learn how science affects foods. In this chemical reactions lesson, students make two kinds of ice cream. They evaluate the different changes based on the ingredients.

For this matter worksheet, learners review the states of matter and the gas law formulas and equations. Students then complete 7 multiple choice questions and 6 problems.

In this chemical bonding worksheet, students review the different types of bonds and calculate the number of valence electrons in molecules. This worksheet has 11 matching and 15 multiple choice questions.

Young scholars investigate the four different ways tectonic plates interact at their boundaries. Using simple available materials, they create models to simulate these interactions present at plate boundaries.

In this compounds worksheet, students describe why metals and nonmetals form ionic compounds and why the formation of ionic compounds are exothermic. This worksheet has 5 short answer questions.

Eighth graders examine the development of the different temperature scales. They experiment with hot and cold temperatures.

Students discover that density is considered a property and that cutting an object in half does not affect its density. They examine the densities of many common substances and make connections.

In this theromochemistry worksheet, students review the kinetic theory of gases and the three phases of a substance. Students calculate how much heat is required to raise a certain mass of solution a certain number of degrees. This...

Students are introduced to concepts in an AP Chemistry class. They work together to complete experiments on different materials. They discuss the results of the experiments.

Students complete activities to learn about the common land features in Alaska. For this land study lesson, students study an overhead for permafrost features. Students define ice wedge polygons, thermokarst, and pingos. Students also...

Fourth graders explore whether the making of homemade ice cream is a physical change or a chemical change in a lab experiment. Students identify states of matter, describe the physical properties of states, and collect temperature data...

Fourth graders explore physical changes and the true life story of Wilson Bentley. They observe the changes that take place with snowflakes. Students discuss what happens when snow flakes melt. They create their own snowflakes using...

In this chemistry worksheet, students examine the concept of covalent bonds with the assessment. The answer key is included on page 3 and 4.

For this chemistry worksheet, 11th graders take a states of matter quiz by matching 10 terms to their definitions, decide if 10 statements are true or false, and answer 2 fill in the blank questions.

In this Earth's forces worksheet, students will review the characteristics of earthquakes, including types of faults. Students will interpret a seismograph read-out from an earthquake. Students will complete 10 fill in the blank...

Second graders point out symbols for high and low pressure that would be found on weather maps. They break into small groups and use a copy of the weather maps file to make observations about the maps and come up with an explanation of...

Students work in small groups. They grab a handful of ice, and place the ice in an empty beaker of ice using a triple beam balance. Students heat up the beaker of ice over a hot plat until the ice has changed into water. They measure...

Eighth graders, in groups, explain the difference between physical and chemical changes.
