An educational lesson focuses on the idea of conservation of matter through a demonstration of the water cycle, a discussion of digesting food, and the path of carbon and oxygen atoms as they change form. 

Third graders study the three states of matter and identify the physical changes that take place between them. There is an initial teacher-led demonstration followed by a meaningful whole-class inquiry. These two activities should lead...

Here's a wonderful lesson on how substances change states. Groups of learners are given trays with a chocolate bar, a piece of paper, an ice cube, and a balloon. During the activity, the groups closely observe the changes that each...

Fourth graders identify a physical change as one that results in a change in size, shape, or state of matter. After an initial teacher-led discussion and demonstration, groups of students get together to perform an experiment which...

Here is an excellent lesson plan on the water cycle and the states in which water exists. Learners identify the features of the water cycle, describe how water changes form, and look at ways that people affect the natural movement of...

Small groups place sand and ice in a covered box, place the box in the sunlight, then observe as evaporation, condensation, and precipitation occur. These models serve as miniature water cycles and demonstrations of the three phases of...

Third graders observe the properties of water and in its different states. In this states of matter lesson, 3rd graders view a video, read The Magic School Bus at the Waterworks and experiment with freezing, melting and boiling...

Here's a fabulous lesson on the life cycle of a butterfly. Youngsters are able to identify and understand the four stages of life. They construct models of a caterpillar and write a sequence story about the life of a butterfly. This...

Students investigate the properties of plastic eggs filled with solids, liquids, and gases and use these observations to hypothesize whether a chicken egg is hard-boiled or raw.

Students investigate common household items and classify them into types of matter. In this matter lesson, students group given items into categories based on their characteristics. They also complete a concept map about matter and...

Third graders explore the concept of evaporation as they observe how the water level changes in a cup that is left out. Working in groups they observe physical changes in a group of everyday items. They record the changes in shape, size,...

An online reading and interactive game bring the path of a carbon molecule to life for your earth science explorers! As an assessment, learners can map out or write about their experience in the carbon cycle. Thoroughly written...

Students participate in various air experiments to understand that air is all around us. In this states of matter lesson, students focus on the role of air in the water cycle. Students understand that air is densest near the ground....

Students relate the states of matter and clouds.  In this environment lesson, students create a chart of information they know about clouds.  Students put an ice cube in a bag and tape to a window. Students watch for...

Students test the stickiness of natural substances. In this adhesion as a property of matter lesson plan, students build a tool to test the adhesion of natural "glues" such as honey, peanut butter, flour and water paste, and jelly. ...

Fourth graders study evaporation and condensation as parts of the water cycle. First they determine the similarities and differences between a cup of water and an ice cube before measuring the volume of ice before melting it, and...

Learners examine the changes as water goes from solid to liquid. For this states of matter lesson, students observe and record the changes to water as it changes from solid to liquid and back to solid.

Fourth graders complete activities to study weather and the water cycle. In this water cycle lesson, 4th graders observe a demonstration of the three stages of water. Students work in groups to complete a water cycle lab activity....

Students explore the water cycle. In this water cycle lesson, students simulate the water cycle by placing an ice cube in a Ziploc bag and observing the changes which occur over time. Students record the mass of the Ziploc bag and record...

Eighth graders make inquiry about the existence of matter. A definition of the word is needed before students can engage in various activities. The application of knowing about matter is done in the working of experiments.

Young scholars investigate the states that water may take. In this physical science lesson, students read the book, Water: Up, Down, and All Around and recall the states of water from the book. Young scholars examine how water takes the...

If you are looking for an outstanding lesson on the Moon for your budding astronomers, look no further! This outstanding plan is full of wonderful, meaningful activities for your charges to engage in. Pupils will discover why there are...

As a stand-alone or as part of the intended unit, this is a valid investigation of what causes condensation to occur.  By limiting the amount of air around a cold cup of water and comparing it to one out in the open, they find that...

Students discover the properties of matter and how they change when composite materials are produced.  In this informative lesson students write up a question and procedure to an experiment then analyze and draw conclusions based on...
