Students investigate the chemical composition of pennies dated 1983 or later. In this chemical composition of American coins lesson plan, students scratch the surface of the penny to expose the zinc core. They put the penny in...

Fourth graders accurately describe various states of matter, Through experimentation, they change a variable to create a new state of matter. Students record their observations about the way matter is changed and the changes that occur...

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,...

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

Building off young chemists' knowledge of the states of matter, kinetic molecular theory is the focus of the unit. Eight days of lessons including multiple demonstrations, one lab experiment, directed instruction, and worksheets,...

Investigate the properties of solid and liquid materials. This very complete slide show is perfect for introducing liquids and solids to children in grades one or two. It describes multiple properties of solids, metals, plastics, wood,...

By viewing this PowerPoint your students' understanding of molecular energy should increase. The properties and inter-particular forces are summarized. The logical progression of information is useful, but more data to demonstrate...

Students explore liquids and solids by conducting in class experiments. In this matter lesson, students define the properties of matter and how heat can change those properties. Students experiment with heating objects such as butter and...

A phenomenal lesson on sound is here for your third graders! In it, learners engage in hands-on activities, watch video, take part in Internet activities, and complete tasks in cooperative groups in order to explore the world of sound...

Graphic organizers, photos, diagrams, and text bring the world of chemical reactions to life. By viewing this presentation, young chemists learn how to recognize when a chemical reaction has occurred, and how to balance chemical...

Fifth graders conduct an experiment.  In this changing matter lesson, 5th graders receive a cup of crystals, record their observations, add water to the crystals and record new observations. Students then discuss the differences...

Learners investigate the physical and chemical properties of a candle before and after it is lit. They conduct a burning candle experiment, and complete a KWL chart and worksheet, recording the results of the investigation.

Ah, caffeine! What would some of us do without it? Teach your high school chemistry class the concept of sublimation as they complete a hands-on experiment to visualize the changes caffeine undergoes during heating and cooling....

What does it take to be considered a smart material? Learners investigate the properties of Nitinol, a smart material, through a hands-on lab activity. They examine the crystal lattice structure and the conditions required for Nitinol to...

Eighth graders observe two types of interactions in a sealed plastic bag. One bag contains baking soda and water, and the other baking soda and vinegar. They determine what evidence indicates that a chemical change is occurring.

In this matter worksheet, students write down 3 causes and effects of physical changes in matter. This worksheet is a graphic organizer.

Eighth grade physical science classes examine why the ice on which hockey is played is slippery. They do so by discussing phases of matter and the molecular motion in each. They read an article on a website and write out answers to...

Take part in a fun experiment and hold an impromptu bouncing contest with your class. Young scientists heat and cool balls before bouncing them to determine whether temperature changes affect how they bounce. The set of...

Middle schoolers analyze given data on density and diameter of objects in space by graphing the data and then discussing their findings. This ninth installment of a 22-part series emphasizes the Galilean moons as compared to other...

The density of the huge planet of Saturn is 0.7 g/cm3, which means it could float in water! In the second part of 22, science pupils explore the size and order of the planets. They then calculate weight and/or gravity and density of...

Can you disprove the law of conservation of mass? Pupils observe the teacher weigh each part of a reaction. Then, the teacher weighs the result of the reaction and everyone sees that the products do not equal the reactants. Then they...

In this chemical change worksheet, learners 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...

Second graders identify three forms of matter- solids, liquids, and gases with 100% accuracy. They observe what happens when they try to put two kinds of matter into the same space and conclude that solids, liquids, and gases occupy space.

Students use descriptive vocabulary to discuss the attributes of matter. Then, they sort objects or pictures by the type of matter they are comprised of. Finally, students match objects of matter with similar attributes and create a...
