Determine physical properties of potential packaging materials. Continuing from previous lessons in the series, the resource asks groups to identify physical properties of the substances. They test for conductivity, solubility, water...

Conclude this chemical change unit by having your class combine two liquids that result in formation of a precipitate. The learners discover that chemical reactions result in new materials. Make sure to consider all of the preceding...

During a three-part lesson, learners make a cabbage juice pH indicator and use it to analyze the waste products of yeast after feeding them with sugar. The intent is to demonstrate how living organisms produce carbon dioxide, which is...

In this matter worksheet, students read statements about changes happening to matter and classify the change as either a physical or a chemical change. This worksheet is a graphic organizer.

Second graders identify physical and chemical changes of matter. They distinguish between physical and chemical changes. They classify changes as physical or chemical.

Fifth graders identify physical and chemical changes. In this science inquiry lesson, 5th graders observe the changes that occur when making bread and butter. Students explain if the product is result of a physical or chemical change.

Third graders explore forms of matter through reading, hands-on science activities, and research using the Internet. Students create a booklet, directions given, that they title and decorate, to later serve as a review visualization...

This is actually a 10-day mini unit on thermal energy for your high school chemists. Every avenue is taken to get learners absorbed in heat: a pretest, a PowerPoint presentation, Internet exploration, demonstrations, lab activities, and...

Does the size of a sample change the physical properties of that substance? It turns out it can! Young scientists combine physics and chemistry to synthesize CdSe quantum dots and record their color properties. Learners should...

How are chemical reactions affected by gravity? Learners explore the phenomenon of effervescence as part of the Christa's Lost Lessons series. They compare findings in an experiment on effervescence to a video of a similar experiment in...

Explore the connection of surface area to bonding within atoms. Learners complete lab investigations to model changing surface area with different sizes and concentrations of atoms. A flour fireball demonstration follows the labs to...

Household materials can be used for more than cleaning! In this collaborative experiment, emerging chemists use products such as vinegar and liquid antacid to explore chemical reactions that commonly occur in the human body.

Build a bridge to learning in a STEM-aligned unit about urban infrastructure. Young engineers explore the many aspects of civil planning and design in a five-day unit. Content includes the challenging aspects of balancing building with...

Eighth graders analyze physical change in mass. In this chemistry instructional activity, 8th graders describe, measure and calculate the amount of physical change occurring in mass before and after the change. Students should be...

In this chemical reactions worksheet, students experiment with several different reactions and identify each as a single replacement, double replacement, synthesis, decomposition or combustion reaction. Students observe the changes in...

Students investigate climate changes by graphing and analyzing ice core data from Greenland and Antarctica. They create, explain and report the pattern of data on a graph of ice core data. In addition they find relationships between the...

In this atomic fingerprint learning exercise, students read about the Bohr model and electrons changing energy levels and emitting energy. They answer questions about the atomic spectrum and the fingerprints for specific atoms.

Students examine physical and chemical properties of plastics, interfaces of plastics, and forms of plastics. In three lab activities, students discover the two characteristic responses of plastics to heating, thermoplastic or...

Students review properties of matter and discuss how materials change when things are done to them. They observe how materials change as a reaction to temperature by following the procedure to make ice cream and recording the temperature...

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.

Young scholars recognize both a physical and chemical change in different substances. They determine which particles actually changed into different substances, and explain if it represented a physical or a chemical change.

In this physical and chemical changes worksheet, students will read 4 different examples of a physical or chemical change and will write in the effect of each of these changes.

Eighth graders practice balancing chemical equations. In this chemistry instructional activity, 8th graders explain why it is necessary to balance equations. They complete practice worksheets individually.

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.
