Demonstrate food preparation techniques of salads, soups, casseroles, breads, meats, poultry and pastries.

First graders observe ice melting and water evaporating. They experiment with sugar and water and read the poem "Matter Really Matters." They define vocabulary words and sing a matter song.

n this geometric lesson plan, students define and identify two dimensional shapes based on their attributes. They complete worksheets based on the geometric concepts.

After reading "Aquatic Alchemy," an article about recapturing water for reuse when in space, your class will use calcium hydroxide or hydrated lime to purify cloudy water. Geared toward high school chemistry or environmental science...

Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation....

It's assessment time! Determine your young mathematicians' understanding of elapsed time with this brief, five-question quiz.

Using helium as an example of propane, physical science middle schoolers experiment with and graph the relationship between temperature and volume in gases. In a whole-class demonstration, they show how molecules behave under different...

In this household chemicals instructional activity, students fill in 10 blanks with answers about testing household materials. Students must also fill out a data table about what color each material turns when placed in cabbage juice....

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...

Fourth graders experiment with different varieties of plants and draw conclusions after performing a series of lab activities. A very helpful student worksheet is given. This is a nicely done introductory lesson for life science.

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 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 explore physical and chemical changes. For this chemistry lesson plan, students will go outside to observe changes seen in nature. Students will then work in the lab to identify changes at different stations prior to doing a...

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...

Students practice scientific inquiry while learning about bubbles. In this lesson about bubbles, students explore characteristics of bubbles. Students move through nine different "bubble" stations following directions and completing an...

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 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...

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 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.

Sixth graders participate in a lesson plan that is about investigating the different layers of the earth and defining how the plates move over the mantle. They engage in a variety of activities and use mathematics to create projects to...

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 investigate plastics and learn they are giant molecules made of carbon atoms. In this polymers and plastics lesson, students perform 3 activities which all include making polymers from household items such as milk and vinegar,...

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...
