Sound, Light and Heat
This lesson teaches students that sound is a form of energy made by moving objects; that sound waves have to have something such as air, water or a solid to travel through; and that high sounds are made by rapidly vibrating objects while low sounds are made by slowly vibrating objects. They learn that light is a form of energy that travels in waves and that we see because objects reflect light to our eyes. They learn that white light is made of all colors and that an object is the color it is because of the color it throws back or reflects. Students also learn that heat is a form of energy; that something can be cold and still have heat in it; that heat goes from hot to cold; that heat can travel better in some things than others; that materials which carry heat well are conductors and those which dont are insulators; and that heat travels in waves.

To a young students not having energy may mean not feeling like playing at recess. They equate energy with movementand so this lesson begins by asking students to think about how they feel when they have no energy. They learn that energy is a form of power that can get work done; that it may come in several different forms; that one form may be changed into another; that energy of motion is kinetic energy; that stored-up energy is potential energy; and that most energy comes from the sun.

Electricity and Magnetism
In this lesson, students learn that static electricity consists of electrical charges that usually dont move and that moving electric charges, or electrons, that keep coming, are called an electric current. They learn that conductors allow current to move and are most often made of metals; that insulators keep current from traveling and are most often made of nonmetals; and that for a current to flow in a pathway, called a circuit, the loop has to closed. They also learn that magnetism is a force some metals have which causes them to attract or repel other metals and that it is related to electricity since we can use one to make the other. Demonstrations make the concepts clear. [color, 42 minutes] $39.95 1EL001

Sun and Stars
In this lesson, students will learn an important concept... that our sun is a star. They see that both the sun and stars are gigantic glowing balls of hot gas....that the sun is bright only because of its nearness to earth and that the stars appear small and dim only because they are so far away. By relating the suns size to a scale they can readily appreciate, they see how big the sun really is. They understand how we are dependent on the sun for heat, light, plant growth and life itself. Students are also introduced to the concept of night and day.

The Moon
This lesson shows students how the earths rotation is responsible for producing our day/night periods. With a globe to represent the earth and a light source to represent the sun, they see the positions of the sun as it would appear to an earthbound observer at various times of the day. Students learn that the earths other motion, revolution, defines the year as one orbit of the sun. This lesson also explains the phases of the moon. Students will understand the relationship between the moons appearance and its position relative to the earth and sun.

The Planets
This lesson takes students on an expedition through the solar system. From NASA footage of the Voyager probe, they will see the planets at close fly-by range. As they watch these stunning images, they will hear descriptions of the planets...the red spot of Jupiter, the rings of Saturn, the volcanoes of Mars, the acid clouds of Venus, the numbing cold of Pluto, etc. Students will also learn that there are other components of the solar system as wellasteroids, comets and meteors.

Plant Differences and Similarities
This lesson on differences and similarities in plants surveys the wide diversity of plant life on the earth. Students see that plants may vary in size, color, shape and habitat; that they may be small, large, aquatic, terrestrial, and fruit and flower bearing; and that they may woody or soft stems and broad leaves or needles, etc. In contrast, students also see that plants are alike in many waysthat they share certain common traits. They learn that most plant have similar parts (roots, stems and leaves) and that most plants, with the help of sunlight, make their own food. They also learn that appearance alone may be deceivingfor example, that a sponge and a Venus's-flytrap may not be exactly what they look like.

Plant Growth
This lesson teaches students about plant growth. They learn that growth is the result of repeated cell division. They learn what a plant needs to thrive and grow, particularly the importance of sunlight, water and soil nutrients. They will understand why some plants bend toward a source of light and how chlorophyll in plants allows them to make their own food. Students see how habitat is critical to the growth of plants and how it determines in large measure what types of plants are able to grow in a specific location. They also learn about germination from seed and about how some plants can be grown by the process of budding and grafting.

Plant Parts
This lesson focuses on plant parts. From discussions of roots, stems and leaves, students will understand the anatomy and makeup of each...how each functions and contributes to the well-being of the plant. For example, they will see how roots anchor plants in soil and how they serve to absorb water and nutrients and how stems support plants and carry water and nutrients throughout. They will see how these parts vary from plant to plant and how plants reproduce. The reproductive cycle is discussed in detail appropriate to this grade level. Students will understand the importance of flowers in attracting insects. They will learn which insects play a vital role in pollinating plants, and understand where fruit comes from, what its real purpose is, and how it varies from plant to plant.

Animal Differences and Similarities
This lesson shows students examples of the way in which animals are different. They will see that they vary in size and shape. They will see that some have legs and arms while others have none and that these differences determine methods of locomotion. They will also see that animals vary in the type of covering on their body...fur, scales, feathers and nothing...and that these coverings offer special benefits to the animals in coping with their environment. This lesson helps the very young student appreciate the wide diversity of animal life in our world.

Animal Growth and Change
In this lesson, students learn how growth and change occur in various kinds of animals. They are first reminded of how they themselves have changed since birth. They will understand that some animals are hatched from eggs and others emerge from their mothers body. They will see how growth and development occurs in other animals...how some are born very immature and need a long period of parental care and how others are born with well developed skills and need a shorter period. The lesson describes how some animals undergo more than just an increase in body size as they grow...how frogs and some insects go through dramatic stage changes as they develop from eggs to adults.

Animal Groups
This lesson presents the classification scheme used to place animals in the traditional groups. Students will see that the plan begins by first dividing all animals into two large groups...those with a backbone and those without. Then they see how each of these groups is subdivided into increasingly more selective groups...that each division includes animals which are more and more alike. To make this concept meaningful, the lesson focuses on the classification of humans, explaining the logic for our being placed in several of the groups. This lesson provides a basis for students understanding concepts they will later encounter. [color, 25 minutes] $39.95 1EL004

Using x-ray pictures of an arm and a model of a human skeleton, this lesson allows the students to compare the shapes and sizes of various bones throughout the body. They will understand that the skeletal system gives shape and form to the body, allows for movement and protects vital organs. From microphotographs, they will gain an understanding of what bone is made of...living cells, calcium and blood vessels. The need for calcium in the diet for the growth of strong healthy bones is stressed. This lesson also teaches the difference between cartilage and bone and gives examples of where they can be found in the body. A comparison of the bodys joints is presented, and examples of each type are listed.

Muscles and Skin
In this lesson, students learn that muscle tissue is responsible for all body movement, even breathing. They learn that muscles can only shorten, that they usually exist in pairs, and that they come in three varieties. They learn to identify muscles of the body as voluntary, involuntary or cardiac types and how these three types differ in appearance under a microscope. Particular attention is paid to the heart muscle, with discussion of its role in supplying blood throughout the body. Students also learn how the skin, the largest organ in the body, protects the body from injury.

Blood and The Digestive System
This lesson teaches how the blood and the digestive systems work together to deliver nutrients to the cells. Students first will learn about blood composition...that it is composed of solid portions (both red and white cells and platelets) and a liquid portion (the plasma). They will compare the appearance and function of each cell type and will understand that blood is indeed a living tissue. They will learn why blood is sometimes bright red and other times dark brown. The lesson stresses that blood not only carries oxygen to the cells but that it also delivers food...food that must first be digested. Students learn the digestive process begins in the mouth, continues in the stomach and is completed in the small intestine. They will gain insight into how food enters the bloodstream at this point and how waste products are eliminated. [color, 23 minutes] $39.95 1EL005

The Basic Senses
This lesson promotes an awareness of the five senses...what kinds of sensations and what types of experiences are associated with each. For example, eating an apple might involve all the senses, but listening to music only one. The lesson also describes the ways in which the senses serve to protect us from danger, warning of street traffic, smoke, heat, and so on. Students learn that the senses carry messages by way of nerves to the brain where they are sorted out and processed. They are given a brief, basic description of the brain and spinal cord. From models, they see which parts of the brain control movement, speech, walking, thinking and so on.

The Function and Structure of Your Senses
This lesson focuses on the ways in which the five senses work...how they gather information from the environment and pass it along to the brain. In the study of vision, students learn the anatomy of the eye and the role each structure plays. In the study of hearing, students learn that the real working part of the ear is inside the head. They learn how the eardrum, three small bones, the cochlea and the auditory nerve work together to provide us with the sensation of sound. They learn that to detect an odor particles must touch the moist back part of the nose. They learn about the tongue map, what a taste bud is, and that tasting food actually involves also smelling it. Students also learn that the sense of feeling is specific for touch, hot, cold, and pain.

The Respiratory, Endocrine, and Excretory Systems
In this lesson, students learn about three of the bodys organ systems...respiratory, endocrine and excretory. They learn how air with its oxygen passes into the lungs, tracing its route through the trachea and bronchi into tiny tubes which enter alveoli, where gas exchange occur. They learn that air is moved in and out of the lungs by breathing muscles. Students learn about seven major endocrine glands from descriptions of what each does and why each is important. They also learn that the excretory system includes the lungs, skin, large intestine and kidneys. They will understand that the kidneys act as a filter, removing waste products from the blood. They will understand that the kidney are vital to life and that it is very important to take care of them. [color, 23 minutes] $39.95 1EL006

The Earth
With images from the space shuttle and satellites, this lesson teaches very young students that the earth is indeed a sphere. They learn that people several centuries ago thought the earth was flat. But they also learn that observations of ships slowly disappearing below the horizon as they sailed out to sea and of lunar eclipses discredited this idea and showed that the earth was a sphere. Students also learn the meanings of the terms circumference and diameter and gain some appreciation for the size of the earth. The video emphasizes surface features of the earth: the land/water ratio, continents, islands, mountain ranges and valleys. Students also learn that the earth has layers, some of which are very hot.

Water and Air
This lesson teaches students about the earths water supply and its blanket of air. The see that two-thirds of the earths surface is covered by its oceans. By contrast, they also see how small is the proportion of fresh water. This serves as an introduction to the need to conserve fresh water and to prevent its pollution. Students are reminded how essential a clean water supply is and the importance of keeping our rivers, lakes, and oceans unspoiled. Along the way they learn a little geography...the names of the oceans, continents and some major rivers. Students also learn how fragile the atmosphere is...how critical it is to life, what its composition is, and what they and others can do to decrease air pollution. They learn that wind is air in motion, why it blows, and how it might be used as an energy source. They see that all weather phenomena occur in our atmosphere.

Rocks and Soil
This lesson teaches students that practically everything in the world about them, including their own bodies, is made of materials that ultimately came from the ground. They learn that the earths surface is composed primarily of rocks and soil...that rocks are made of a variety of minerals. They see from samples that rocks may be classified into three large groups, according to their formation...igneous, sedimentary, and metamorphic. They also learn that soil is a combination of pulverized rock, minerals and organic matter and that it may be classified as clay, sand, or loam. The lesson emphasizes that the earths natural resources are finite and therefore must be conserved. [color, 25 minutes] $39.95 1EL007

Inside the Earth
In this lesson, students learn about the composition of the earth. First, they are reminded that like a basketball the earth is a sphere. But unlike a basketball, it is not hollow. From comparing a cross-sectional drawing of the earth to that of an avocado, students learn that the earth is made of three layersthe crust, the mantle and the core. They understand that scientists have had to obtain this knowledge indirectly by analyzing data from earthquakes and volcanoes. They see why it is important for builders of skyscrapers and drillers of wells to know the composition of the crust. They learn that the core may be made of partially melted metal and that the earth plates rest on a moveable mantle of partially molten rock.

Wind and Water Erosion
This lesson shows students how the earth undergoes constant change from the elementswater and wind. They understand that moving water can sculpt rivers, ravines, remove top soil and smooth rocks and mountain sides. They see that water combined with carbon dioxide may eat away at certain kinds of rocks and may hollow out caves and leave behind odd formations; that frozen water and growing plant roots can pulverize rocks; and that moving glaciers can leave their mark on the soil. Students also see that wind can create sand dunes and blow the top soil away from the land.

Earthquakes and Volcanoes
This lesson shows students learn how two natural phenomena, earthquakes and volcanoes, work to change the face of the earth. They understand how shifting plates under the surface collide, exert pressure and finally slip, producing the violent motion of a quake. They see how earthquakes are measured and what people can do to protect themselves from injury. They understand that localized earthquakes may also be produced by erupting volcanoes; that earthquakes may, in turn, produce volcanoes. They will see how the eruptions of volcanoes may have worldwide meteorological implications. They also learn that a volcano in its old age may be transformed into a geyser.

Water PollutionThis lesson reminds students how important a clean water supply is and how many ways water is used in their own homes. They see that water can become polluted in a number of ways: by the release of raw sewage, the dumping of substances such as phosphates and mercury, the runoff of insecticides, the spilling of oil, and the release of heated water into streams and lakes. They learn the basic steps in sewage treatment, how phosphates produce algae and bacteria, how mercury and insecticides progress through the food chain, how oil spills are contained, and why heating of the water supply by industry is harmful. They also learn what is being done to minimize the effects of these factors on our water supply.

Air Pollution
In this lesson, students learn about the various sources of air pollution...that most of it is the result of human activities. They see, for example, how the automobile, the burning of fossil fuels in power plants, and, in fact, the burning of fuels in general release contaminants into the air. Specifically they will understand how the burning of sulfur-containing fuels release sulfur dioxides into the air, causing acid rain, and how the release of carbon dioxide contributes to the greenhouse effect. They learn how efforts are being made to reduce these pollutants through the use of scrubbers in industry and by the use of converters in cars and how reducing automobile travel and use of electricty could help. The lesson also stresses that some air pollution is natural, including that caused by volcanoes, wind and forest fires.

Land Pollution
This lesson shows students how important it is to preserve the beauty of the land. They learn just how much garbage the average family produces each week and what kind of materials it includes. They see that it is important to reduce as much as possible the volume of trash we generate, that recycling is a primary means for accomplishing this goal, and that littering is harmful. Students also learn that government and industry are beginning to take an active role in helping reduce land pollutiongovernment by enforcement of regulations and industry by the installation of scrubbers in exhaust systems, by reclamation efforts of foresters and strip miners, and by the treatment of toxic chemicals.
