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...

For 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.

Young scholars 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...

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 learning exercise, learners 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...

Learners 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.

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

Students 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 higher...

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

Learners 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. Learners determine the heat required to melt one mole of ice using hot water and ice...

Students investigate the properties of matter. In this properties of matter lesson, students observe containers of different metals and discuss their properties including density. Students find the density of an unknown metal and of...

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...

Students convert between the different metric units after reading the Fairy Tale of King Henry. They measure various candies in a baggy using the width of their index finger. They record results to the nearest index finger width on a...

Fourth graders identify the attribute of volume of an object. Units of measurement are reviewed and utilized in this instructional activity.

Students find the mass, volume, and density of various objects. In this density measurement activity, students observe how same-sized objects can have different masses, then use water displacement to find the density of each object and...

Students examine the changing states of water. In this solid, liquid, gas lesson, students discover that water changes when heated or cooled. Students make predictions and then use the interactive whiteboard to "heat and...

Learners explore the concept of frost depth. In this frost depth lesson, students conduct a scientific investigation that requires them to use a frost tube to measure, record, and graph frost depth data.

Learners understand that a psychrometer is a weather instrument used to detect humidity. In this psychrometer lesson plan, students build a psychrometer.  Learners use their psychrometers to measure humidity activity.

Second graders analyze the effects of sunlight on a glass of water by using the thermometer to measure its temperature. They predict and measure the difference between water outside in the sun and shade and inside. They role-play a game...

Third graders read a thermometer with accuracy, record observations and data, and infer conceptual meaning. They integrate mathematical charting and graphing skills to organize their data. They explore what happens when they touch or use...
