What makes particles attract? Here, learners engage in multiple activities that fully describe colligative properties and allow the ability to critically assess the importance of these properties in daily life. Young chemists...

In a neat and straightforward manner, this PowerPoint delivers basic introductory information on the properties of matter, physical and chemical changes, and pure substances vs. mixtures. It also defines the states of matter. For some...

Scientists have been studying exothermic reactions before they were cool. The lesson begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed to...

In this gas laws worksheets, young scholars figure volumes, densities, molar masses, reactions, and solve equations as they encounter 14 gas laws questions.

Students engage in a lesson which explores the wate cycle. They get to see some very entertaining video, do fun hands-on activities and gain a better understanding of evaporation, condensation, precipitation and collection.

Students determine the validity of Charles' Law. In this Charles' Law lesson plan, students measure the volumes of a gas at two different temperatures. They determine the volume at a high temperature and predict using Charles' Law what...

In this gas laws worksheet, students use textbooks and dictionaries to find the definitions of 20 terms associated with the gas laws.

Learners use a NASA satellite data to contrast amounts of cloud coverage over different climate regions in Africa. They explore how Earth's major air circulations affect global weather patterns, and relate to local weather patterns.

For this identifying the weather terms activity, students read phrases about the weather and choose the term being described. Students choose 11 multiple choice answers.

How many parts make up the water cycle? How many things on Earth rely on water as a system? Learn more about the water cycle in an informative and colorful poster. Print and hang, or project the graphic in the classroom for optimal use.

Students identify different climate regions and local weather patterns.  In this cloud coverage lesson students use NASA satellite data and import it into Excel. 

Young scholars examine the similarities and differences between weathering and erosion. They participate in a lab in which they test the effects of different materials when exposed to weathering and erosion. They record their observations.

Thunderstorms, tornados, blizzards, hurricanes. These extreme forms of weather are the focus of an article on a two-part reading comprehension worksheet. After reading the passage, kids use information in the text to respond to a series...

Here is a suitable set of slides to use when teaching about the layers of the atmosphere, climate, global winds, and types of clouds. These slides will support a few different lectures. You will probably want to replace the diagrams with...

What is thunder? After reading a short article about extreme weather, middle schoolers must use information in the text to explain this weather phenomenon.

In the summer of 1815, snow fell every month in New England. Was this related to the volcanic eruption of Tambora in Indonesia earlier in the year? Young scientists design their own experiments to research the long-term effect a volcanic...

This resource provides a short experiment for students to explore how clouds are formed.

In this solutions worksheet, students calculate molality and mole fraction. Students define colligative property and determine what affects the solubility of gas in solvents. This worksheet has 2 short answer questions and 9 problems to...

In this chemistry terminology worksheet, students review and discuss nineteen terms associated with chemistry and then locate and circle each term in a word search puzzle.

In this physical equilibrium activity, students compare polar and non-polar compounds and the solubility of specific solutes in solvents. Students calculate molar heat, molar solubility, and molality for specific reactions. This activity...

In this chemical solutions worksheet, students determine the molecular weight of a substance, determine the boiling and freezing point of solutions, and determine molarity of a solution. This worksheet has 3 problems to solve.

Students determine that some liquids are able to evaporate more readily than others. They create a balance using cups and a ruler to determine which end of a strip dipped in alcohol or water evaporates the fastest, hence loses the most...

In this phase diagram worksheet, students use a phase diagram to determine the critical point, phase boundaries, and phase transitions. This worksheet has 20 problems to solve.

In this electrolytes worksheet, students calculate percent composition, determine the electrical conduction of electrolytes, and explain the Tyndall effect. This worksheet has 7 problems to solve.
