Young scientists play tag as they act out the food pyramid in the ocean ecosystem. Energy circles pass from the smaller prey to the predators and at the end of the activity, a data chart and analysis questions allow pupils to apply their...

Young scientists observe the spectra of elements and compare that to the Doppler effect. Hook scholars from the beginning all the way to the extension activities in this 5E-format lesson. 

In this matter activity, students identify words and match them to their definition. Students identify words dealing with matter, its physical changes, and the effect of heating and cooling matter. This activity contains nine matching...

Students examine the different changes in matter.  In this chemical change lesson students determine the amount of reactant made in a reaction using the law of conservation. 

To guide learners through observations of chemical samples in the lab, this resource asks them to give all formulas and complete the attached data sheet.  There are multiple questions about categories of elements and general...

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,...

Examine the nature of landfills through experimentation. Scholars build miniature landfills and monitor changes over a six-week period. Observations allow individuals to draw conclusions about the different types of trash and their...

Blue-tinted water is added to unknown liquids that have been tinted yellow to find out how they interact. This is a memorable activity that is part of an investigation on the properties of liquids, which is part of a unit on the...

Is it easy to make snow? Scholars use critical thinking skills as they investigate the concept of polymers by making snow. The class tests several different variables and takes measurements over the course of several days. They then...

Students study the difference between physical and chemical properties. They also discuss changes in matter, known as physical and chemical changes. They observe and discuss several demonstrations of both physical and chemical changes

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...

A review of a full unit on energy and matter, this slide show starts with basic definitions of states of matter and their mass. It then develops the ideas of the forces that that matter can exert. Details about bonding within matter and...

Third graders examine the phase change between solids and liquids and determine it to be a physical change. Ice is the perfect item to use to demonstrate this phase change. Pupils experiment with measuring and weighing solid ice and the...

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 size have to do with it? Learners analyze different mixtures, both homogeneous and heterogeneous, to discover the properties related to the size of their particles. The activity connects these properties to those of...

Students recognize that some changes to matter are reversible and some are not.  In this matter lesson, students experiment a physical and chemical change. Students record experiment results in their science journals. Students act...

Sixth graders complete several experiments about chemical and physical changes. In this physical and chemical science activity, 6th graders complete 6 experiments about chemical and physical changes. Students examine the processes of...

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...

Eighth graders participate in several science activities to note chemical or physical changes after discussion. They understand that all matter has definite structure which determines physical and chemical properties.

Eighth graders, in groups, explain the difference between physical and chemical changes.

In this physical world instructional activity, students review concepts relating to the chemical and physical properties of matter, density of matter, and if matter is a solid, liquid, or gas. This instructional activity has 9 terms in a...

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.

Fifth graders evaluate the physical properties of 5 powders. Each powder is subject to different conditions. They describe each observation as with a chemical change or a physical change.

Students investigate what matter is and how it changes states.  In this physical properties lesson, students examine the vocabulary database and identify the characteristics of the three phases of matter.  Students perform a...
