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,...

Students observe and discuss what happens when water turns to ice and when ice turns into water. In this freezing and melting lesson plan, students observe ice and water and complete hands on activities that change their properties.

Students complete a unit of activities to learn about states of matter and how to measure matter. In this matter lesson, students complete 8 lessons to learn about matter, its states, and how to measure matter.

Students explore the states of water. In this water states lesson, students observe ice over time and the changes that take place. Students read a related text and draw their observations in a journal entry. Students discuss the...

Second graders complete activities to measure motion and learn about the Earth's history. In this motion and Earth history lesson, 2nd graders discuss sound and complete a matching sound activity. Students then study the history of Earth...

Students explore matter. In this physical science lesson, students role play the 3 states of matter forming "liquid" molecules and "solid" molecules with teammates. Students perform an experiment in which the result illustrates that two...

Students explore the three states of matter. In this physics lesson, students are shown examples of solids, liquids, and gases. Students make cookies and identify the three states of matter during the baking process.

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...

Students investigate density and salinity of water. In this density and salinity lesson plan, students find the density of objects and liquids and show the relationship between the salinity and density of water. Students add salt to...

In this metric system worksheet, students convert measurements of volume from the English system of measurement to the metric system. They also convert within the metric system and answer questions about volume measurements.

Students observe water change from a liquid to a gas state when heated and then return to its liquid stage when cooled. They learn that gas molecules move faster than liquid molecules. They discover physical properties that describe how...

In this metric system worksheet, students complete notes on measurements used in the metric system, the metric system prefixes and estimates of measurements of length in centimeters.

In this water on planetary surfaces worksheet, students read about the Galileo spacecraft and the surface of Jupiter's moon Europa. They read about the energy needed to keep the water in a liquid state on Europa. Students solve 4...

Students compare the freezing temperature of two substances by conducting an experiment to freeze liquid ice cream. They vary the amount of salt used in the ice cubes during the freezing procedure to determine the change in the...

Students explore the concept of density. In this density lesson plan, students determine the density of a crown and a sample of clay. They hypothesize about the densities of 4 liquids they are given including molasses, cooking oil, a red...

Young scholars identify the physical and chemical properties of matter. They review the types of matter. Students list the four states of matter (Solid, Liquid, Gas and Plasma). They recognize and describe the different types of matter.

Young scholars investigate the pH of a liquid.  In this middle school mathematics/science lesson, students collect and analyze data regarding the pH of various liquids.  Young scholars display their data in various types of...

High schoolers investigate osmosis and diffusion in a liquid environment. In this osmosis lesson plan, students use dialysis tubing made into bags and filled with 3 different solutions. They observe the movement of water molecules into...

Learners explore the water cycle. For this earth science lesson, students observe and measure water in a closed container and in an open container. Learners record their observations and compare their sets of data to draw conclusions...

Students determine the heat of fusion of ice. In this heat of fusion lesson plan, students use a calorimeter to measure the molar heat of fusion of ice. Students determine the heat required to melt one mole of ice using hot water and ice...

High schoolers investigate the properties of matter. In this properties of matter instructional activity, students observe containers of different metals and discuss their properties including density. High schoolers find the density of...

Young scholars participate in experiments at five stations to practice measurement. In this measuring activity, students are presented different produce and objects and must measure with an appropriate tool. Young scholars use metric and...

Second graders investigate the properties of solids and discover how to classify them. Using rulers, they measure various solids on display. In groups, they play an identification game where one students names a location, such as the...
