Students observe a teacher demonstration o classifying matter by its physical properties of shape and size. After discussing the definition of matter, students describe the state of matter. They sing a song to the tune of "Bingo." In...

Matrices help solve systems of equations in chemistry, computer graphics, circuitry, probability, and more. The second lesson in a seven-part series focuses on using matrices to balance chemical equations. Pupils rely on the Law of...

In this conservation of mass worksheet, middle schoolers experiment with vinegar, baking soda, a balloon and a flask. They compare the mass of the closed system of reactants before the experiment to the mass of the products after the...

Students experiment with water and ice. For this states of matter lesson, students explore how water can change from a solid to a liquid and back again. They discuss and write about the results of the experiment in a science journal.

Fifth graders compare physical and chemical changes. They perform a simulation experiment/activity that replicates what happens in the stomach as food is digested by stomach acids.

Students study reaction rates, what determines how fast a reaction happens and how the chemical changes occur.  In this reactions activity students complete a lab where they use Alka-Seltzer to observe reaction rate and create a...

Students investigate how salt affects the state of ice. In this ice cream making lesson, students change the freezing temperature by adding salt and observing the results. Students use experimentation and comparison to see how chemicals...

In this moles activity, students read about mole and learn how to calculate the number of moles in specific mass of compounds. This activity has 14 problems to solve.

In this chapters 2 and 3 science guided reading worksheet, students read corresponding material pertaining chemical reactions and the periodic chart answering 40 fill in the blank questions.

Students engage in a lab project to study chemical reactions. They use guided questions to help facilitate the lab experience and come to the correct outcomes. The activity does not contain a true understandable objective. The activity...

Students describe and define chemical reactions. They design a laboratory experiment, collect data and analyze data.

Students observe and describe a chemical reaction. In this chemistry lesson, students record observations of the materials they will be using, then follow a written procedure to perform the experiment in a baggie and record their...

Young scholars investigate the concepts of conservation of mass and simple chemical reactions. Students complete lab experiments and record all observations as well as conduct experiments on their own to determine which reactions...

Young scholars verbalize a simple particle theory, They apply their particle theory to explain what happens during chemical reactions and how this theory supports the law of conservation of matter. Pupils comprehend that the atomic...

In this chemical change worksheet, students conduct 4 experiments set up around the room. They follow the instructions at each station for each experiment and list the physical properties and observe any changes at each station. Students...

Fourth graders examine and identify chemical and physical changes in a variety of substances. They observe a vinegar and baking soda demonstration, and a water, laundry detergent, and Epsom salt mixture demonstration. They discuss the...

Seventh graders distinguish between physical and chemical changes in both natural and technological settings. They identify the reactants and products for a given chemical reaction. they then write simple chemical equations given the...

Finding new drugs has been likened to finding a needle in a haystack. How do pharmaceutical companies do it? One of a small series of four informative leaflets examines combinatorial chemistry, the method at the forefront of new drug...

The cycle of energy is important to many different systems on Earth. Scholars use questioning and observation to investigate the differences between renewable and non-renewable resources and how they relate to global changes. They...

For this chemical and physical change worksheet, students conduct a variety of experiments with unknown solutions and make observations. Students determine if the properties of the solutions have changed and if there is...

Students gain an understanding of how systems and organs in the human body work. They create their own fictional account of a trip through the human body, and describe one response the body makes to stimuli.

In this chemical and physical change worksheet, students use a sugar cube and observe its physical properties both when it is whole and after it is crushed. They heat the sugar cube and record 5 properties of the matter while being...

Third graders investigate Newton's law of Motion.  In this chemical reaction lesson, 3rd graders participate in an experiment with rockets to study Newton's law. Students observe the effects of a chemical reaction made by combining...

Fifth graders investigate evidence for changes in matter that occur during a chemical reaction.
