Winter, spring, summer and fall. We know what happens in our own backyards at these times during the year, but it isn't the same everywhere in the world! When it's warm and sunny where you are, it might be very different in other places of the world. Why do the seasons change? And what causes different regions in the world to have different climates? These and other questions are answered in All About Climate & Seasons, where young students will learn about these yearly changes through engaging examples and explanations. A hands-on investigation shows the effects of direct sunlight on areas of the world, while Dr. Jon Nese, chief meteorologist at The Franklin Institute Science Museum in Philadelphia, demonstrates the concept behind the device known as an orrery.

Natural resources include sunshine, fresh air, plants, animals, minerals and fossil fuels like coal, oil and natural gas. These things are resources because they are needed by living things. They are "natural" resources because they are all products of nature. In All About Natural Resources, children will learn about these resources and more, discovering along the way what makes some natural resources renewable and others nonrenewable. See how wind turbines provide an alternative to fossil fuels as a means of providing energy, while a fun, hands-on demonstration shows children how they can build their own simple water treatment system.

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.
