Most kids understand that many plants sprout from seeds, grow flowers and make new seeds, and then the whole process starts all over again. What they may not realize is that this is an example of a life cycle, and it applies to people, too! In All About the Human Life Cycle, students will discover that there are stages that all of us pass through as we grow: birth, infancy, childhood, adolescence and adulthood. Each of these is described by using real-life examples against the backdrop of a family picnic. The concept of a cycle is stressed, making it clear that the cycle of life repeats again and again with each new baby that is born. A fun activity is included in which kids witness the stages of a life cycle up close through observing the metamorphosis of a caterpillar into a butterfly. Part of the multivolume Human Body for Children DVD Series in the Schlessinger Science Library. Part of the Schlessinger Science Library for Children Collection. This title is based on the concepts outlined in the National Science Education Standards for Life Science: characteristics of organisms, life cycles of organisms and organisms & environments. A Teacher's Guide is included and available online. 23 minutes. Grades K to 4.
The explosively dangerous eruptions of volcanoes are always a sight to behold. As visually dazzling as they can be, volcanoes also play a very important role in the creation of land formations around the world. In All About Volcanoes, children will learn the ins and outs of these lava-spewing mountains, examining their anatomy while learning about three major types: shield, cinder cone and composite volcanoes. A visit to Mammoth Mountain in California focuses on the signs that this dormant volcano may be coming to life, while an informative, hands-on activity demonstrates how a volcano erupts by building a useful model. Part of the Earth Science for Children DVD Series. A teacher's guide is available online. 23 minutes. Grades K to 4.
Sound, light, heat and even earthquakes travel in waves. Waves are a transfer of energy, and understanding them allows us to better understand the world around us. Students learn about the common characteristics of waves through real-life examples and clearly illustrated graphics. A fun, hands-on activity will help students understand these basic concepts. This program is one of 11 volumes in the Physical Science for Children DVD Series in the Schlessinger Science Library. Part of the Schlessinger Science Library for Children Collection. This title correlates to the National Science Education Standards for Physical Science -- properties of objects and materials, position and motion of objects and light, heat, electricity and magnetism. A Teacher's Guide is included and available online. 23 minutes. Grades K to 4.

How does a glacier work? This model will give students the opportunity to observe the effects of glacial movement without having to endure glacial time. First model depicts a glacier in its active stage, while the second model shows post-glacial conditions. Using the second model, students can create their own glacier using ice and sand to observe glacial melting and deposition of glacial till. Each model is 18" x 24", formed in high impact plastic. Teacher's guide included. Set of 2.

Aluminum Metal (20 gauge sheet) - 12" x 12" x .032"
500 grams of Aluminum Metal Shot.
Aluminum metal shot is often used in classrooms for chemistry experiments and demonstrations, such as studying chemical reactions, investigating metal properties, and exploring concepts like density and reactivity. It is commonly used in reaction experiments with acids (like hydrochloric acid) to produce hydrogen gas, allowing students to observe the properties of metal reactivity and gas evolution. Additionally, aluminum shot can be used in physics experiments to study thermal conductivity and heat transfer due to its high thermal conductivity and low density.
