Crystals are more than meets the eye! Can learners tell them apart simply by observation? As they examine five samples with a magnifier, they find that appearance alone is not enough. This serves as an introduction to a mini unit on...

Fifth graders explore American colonial life. In this interdisciplinary history and science lesson, 5th graders participate in several hands-on activities that require them to make colonial products that involve physical or chemical...

Fifth graders evaluate evidence that indicates a physical change has occurred. In this colonial living lesson, 5th graders explore the science involved in the making of items used in colonial life, such as, bread, butter, soap, candles,...

Learn about polymers while playing with shrinky dinks. Young scholars create a shrinky dink design, bake it, and then record the area, volume, and thickness over time. They model the data using a graph and highlight the key features of...

Sometimes, despite the best laid plans, the unexpected will occur. Learners witness this firsthand as they carefully design an experiment to determine the time needed for ice to melt in salt water or pure water. They uncover facts not...

A collection of ten slides reveals bright graphics and photos. Though the title is "Properties of Matter," the content is incoherent. You will find a couple of slides on chemical reactions, a few on the example of the S.S. Hindenburg...

Some say cooking is an art—and a science! Scholars scope out the savory subject of molecular gastronomy with a series of related activities. The teacher's guide contains printable worksheets and helpful tips for implementing the lesson.

Le Chatelier's interest in thermodynamics and building materials such as cement and plaster led to the Le Chatelier Principle in 1884. Activity 13 in a series of 36 extensively explores chemical equilibrium. Learners read about...

Topping this worksheet is a comprehensive collection of notes about phase changes. The phase change graph is displayed, along with formulas for the gas laws, and information relating energy to change of phase. After reviewing these...

Students discuss the definitions of physical and chemical properties and changes. They vaporize a solution of salt and water, observing the sodium chloride that is left behind.

In this science worksheet, students read about chemical changes. Students also answer 3 comprehension questions about the reading.

Students observe and analyze weathering. In this earth science lesson, students demonstrate physical and chemical weathering in two experiments, then write questions for a class Jeopardy game.

Fourth graders expand their knowledge about how the physical properties of a substances can be changed. They are given multiple opportunities, using first-hand experiences and familiar objects in different contexts, to identify...

Students examine the differences between elements, compounds and mixtures. Using diagrams, they compare and contrast atoms and molecules and describe various chemical reactions. They distinguish the differences between ionic and...

Students differentiate physical and chemical change. In this chemistry lesson, students list examples of those changes. They apply what they learned in a Jeopardy style team game.

In this review of physical science learning exercise, students use recall to answer multiple choice questions about electricity and chemical changes. Students answer 25 questions.

Fourth graders observe what is happening when an Alka-Seltzer tablet is placed in a clear cup of water. They observe the release of carbon dioxide gas. Pupils answer the question of how much as is released by observing the experiment...

Young scholars compare the carbon dioxide content of four different samples. In this chemistry lesson, students research the causes of global warming. They explain how humans contribute to rising global temperature.

Fifth graders discuss the differences between chemical and physical changes. In groups, they complete experiments and discover how a physical chnage can be reversed. To end the lesson plan, they review the steps of the water cycle and...

A full-fledged practice final prepares pupils for their general chemistry final exam. If they complete these 57 multiple-choice questions correctly, they will be well-prepared. Note: even though the questions are multiple-choice, there...

Take charge of your class and provide them with an electrical experience! Individuals investigate the basic principles of electricity and magnetism by creating a model to test electric current and the amount of electricity generated....

How does examining an ice core tell us about weather? Learners set up and explore fake ice cores made of sugar, salt, and ash to represent historical snowfall and volcanic eruptions. From their setups, scholars determine what caused the...

Learners see evidence of chemical reaction and follow the scientific method to hypothesize, observe, and reach conclusions. They conduct a series of egg based experiments such as forming crystals and complete journal activities as a...

Students conduct a number of simple experiments, collect and categorize the results as either chemical or physical change. The lesson uses connections to folklore, science fiction and comic books to assist each student as they make...
