In this conservation of mass worksheet, learners design an investigation to demonstrate the Law of Conservation of Mass. Students describe their investigation, collect data, graph the data and write a conclusion about what they discovered.

Fourth graders explore whether the making of homemade ice cream is a physical change or a chemical change in a lab experiment. Students identify states of matter, describe the physical properties of states, and collect temperature data...

Learners examine how scientific theories are developed. In this matter instructional activity, students explore the basic idea of quantum theory. They create a timeline of scientists, their contributions, and discoveries.

In this matter worksheet, students complete a graphic organizer by describing the properties of matter, the changes of matter, and how matter can form mixtures.

In this changes of matter worksheet, students write in what happens when water is heated and when water gets very cold. This worksheet is a graphic organizer.

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 investigate chemical reactions. In this physical science lesson, 5th graders make dry ice root beer and identify the type of change that occurs to the root beer mixture.

In this conservation of mass instructional activity, 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...

Does your class feel unprepared for the upcoming exam? Use this video to review the simple harmonic motion concepts that will appear on the AP Physics exam. While maintaining interest and a fast pace, the presenter not only reviews...

Can you move like a photon? Young scholars use a maze to reproduce the straight line motion of a photon. The second in a six-part series of lessons on the sun has learners measure angle of incidence and refraction to determine the path...

Young scholars find the density of diet soda and regular soda. In this density lesson plan, students measure the mass of a graduated cylinder with 10 different volumes of each soda. They find the mass of the liquid alone and use the...

Fifth graders examine the differences between chemical and physical changes. As a class, they are read a scenerio and determine whether it was deliberate act or not. In groups, they observe the changes of an alka-seltzer tablet and...

Students look for examples of chemical and physical changes in the world around them and complete "What's Happening in My World" worksheet.

Students investigate if heat can change the form of matter. In this physics lesson plan, students use heat sources to observe the changes in an ice cube. Students graph which heat source changed the matter the fastest.

First graders explore the properties of matter. In this states of matter lesson, 1st graders conduct scientific investigations that require them to mix, cool, and heat objects in order to observe changes in the properties of matter.

Young scholars investigate the kinetic-molecular theory. In this state of matter instructional activity, students consider the differences of melting glaciers, melting icebergs and investigate on what happens when submerged water melts.

Young scholars experiment with balloons, soda water and raisins to find out about the states of matter.  In this solids, liquids and gases instructional activity, students complete a group activity with balloons to recognize the...

There are so many topics touched upon in this Jeopardy-style science game, that it is difficult to classify! The categories include electricity, matter, ecology, earth and space, and scientific investigation. This would best be used at...

In this changes in matter instructional activity, learners draw a picture that shows physical and chemical changes. This instructional activity has 7 fill in the blank questions.

Third graders are introduced to the topic of matter. As a class, they brainstorm what they already know about matter and its properties. After completing a worksheet, they participate in an experiment in which they observe matter in...

Pupils explore water as it changes states of matter. In this physical property lesson, students use observation, measurement, and communication skills to describe changes in water as it goes from a solid to a liquid and back again.

In this chemical change worksheet, students review physical changes such as evaporation and condensation before working with chemical change. They conduct an experiment with vinegar and baking soda before recording the chemical changes...

Students investigate water in its solid and liquid form. In this states of matter lesson, students experiment to see what happens as water goes from a solid, ice, to a liquid, water, and back again. They write about and illustrate the...

Students examine water. In this chemistry lesson, student examine the physical properties of water and how it changes from a liquid to a solid or a gas. This lesson contains links to a second and third complimentary lesson on...
