Students will discover the concept of joining groups together to make a new group by using objects from pies to penguins. They learn about addends, sums, and plus and minus signs, and will learn tips for adding single- and double-digit numbers and for adding with zero, making ten and ordering addends.
Learn about earth's atmosphere which protects the planet from meteoroids and ultraviolet rays, provides air, and what makes this layered blanket of gases so important. NASA footage and hands-on investigations.
In this video, kids measure time in seconds, minutes and hours, and order events by using words like before and after. They also learn about A.M. and P.M, about how to use a calendar and about how to estimate time.
In this video, kids learn to write money values using numbers, symbols and decimal points. They also discover how to spend wisely by using estimation and comparison, and how to give and receive the change.
In this video, kids learn to measure length, weight, temperature and capacity in different unites with a variety of measuring tools. The video also shows the value of using standard units like those found in the U.S. Customary System and the Metric System.
In this DVD, kids separate groups that make up a whole using objects such as cookies and crayons to learn how many objects are left, how many items are missing and how many more there are. They learn about the minus sign and how to write subtraction equations. Children also learn tips for subtracting single- and double-digit numbers as well as subtracting with zero.
Building on the scientific and investigative knowledge that students have acquired over the years, this program delves deeper into the theory of "Science as Inquiry." This program helps students recognize the intricate relationship between explanation and evidence through engaging examples.
Viewers explore the historic experiments by scientists Thomson and Rutherford, which led to the discovery of subatomic particles and the development of nuclear theory. Students learn the shape of the periodic table is a direct result of the microscopic structure of atoms that make up all the elements. Baic high school chemistry concepts are reinforced, along with clear explanations of the evolution of atomic models through quantum mechanics.
A chronicle of the historical development of the concept of an "element" from the ideas of ancient Greece through modern quantum theory. Viewers learn that as scientists like Boyle, Dalton and Lavoisier began to recognize patterns in the behavior of chemicalsk they sought a unifying principle that would explain why different elements had different properties.
