This activity provides an opportunity for students to work on spatial visualization and number sense together. Learners are presented with a hundred grid and told there is another printed on the reverse side. They must work out the unseen numbers for several positions on the grid. Ideas for implementation, extension and support are included along with a printable sheet of grids.

This problem challenges children to make sense of information presented by applying their knowledge of number properties and to make and test conjectures based on that information. Students try to determine the secret number property or rule by examining the numbers that fit the rule and the numbers that don't fit the rule. The Teachers' Notes page offers rationale, suggestions for implementation, discussion questions, ideas for extension and support and a link to an interactivity of the game.

This brief article advocates the use of arrays to model the commutative and distributive properties as well as the inverse relationship between multiplication and division. The author explains how arrays also help children form mental pictures that support their memory and reasoning.

This video segment adapted from A Science Odyssey looks at the invention of nylon.

Learn where diamonds originate and how inclusions trapped within diamonds help geologists determine their age in this video segment from Nature.

In this video segment adapted from NASA, astronomer Michelle Thaller introduces the world of infrared light and demonstrates how infrared cameras allow us to see more than what the naked eye can perceive.

This video segment adapted from NOVA illustrates why carbon is at the center of life on Earth. It also asks whether carbon-based life might exist on other planets.

This bilingual curriculum and resources guide and is designed to help elementary school teachers organize instruction to increase achievement of Hispanic primary-grade children whose first language is not English. The guide offers a curriculum plan, instructional strategies and activities, suggested teacher and student materials, and assessment procedures. Because language development is a fundamental co-requisite for learning mathematics and science concepts, processes and skills, the lessons in many instances begin with literature (e.g., stories, books) and discussion activities that set the stage for posing questions and presenting conflicting situations related to the Big Ideas in mathematics and science that are the focus of the lesson.

This survey should give you enough knowledge to appreciate the impact of chemistry in everyday life and, if necessary, prepare you for additional instruction in chemistry. Throughout each chapter, I present two features that reinforce the theme of the textbook—that chemistry is all around you. The first is a feature titled, appropriately, “Chemistry Is Everywhere.” Chemistry Is Everywhere” focuses on the personal hygiene products that you may use every morning: toothpaste, soap, and shampoo, among others. These products are chemicals, aren’t they? Ever wonder about the chemical reactions that they undergo to give you clean and healthy teeth or shiny hair? I will explore some of these chemical reactions in future chapters. But this feature makes it clear that chemistry is, indeed, everywhere. The other feature focuses on chemistry that you likely indulge in every day: eating and drinking. In the “Food and Drink App,” I discuss how the chemistry of the chapter applies to things that you eat and drink every day. Carbonated beverages depend on the behavior of gases, foods contain acids and bases, and we actually eat certain rocks. (Can you guess which rocks without looking ahead?) Cooking, eating, drinking, and metabolism—we are involved with all these chemical processes all the time. These two features allow us to see the things we interact with every day in a new light—as chemistry.

Short Description:
Introductory Chemistry is designed to cover the wide range of topics typically covered in a one-semester chemistry course for non-science majors. This re-mixed textbook is an adaptation of chapters predominantly from three open source chemistry texts- Boundless Chemistry by LumenLearning, Chemistry: Atoms First (2e) by OpenStax, and General Chemistry: Principles, Patterns, and Applications by Salyor Academy. This specific text was created to align with the flow of topics taught in the course Chemistry 1010 at Utah State University.

The goal of this textbook is not to make you an expert. True expertise in any field is a years-long endeavor. Here I will survey some of the basic topics of chemistry. This survey should give you enough knowledge to appreciate the impact of chemistry in everyday life and, if necessary, prepare you for additional instruction in chemistry. Throughout each chapter, I present two features that reinforce the theme of the textbook—that chemistry is all around you.

This animation from KET's distance learning physics course demonstrates the mathematical formula for a scientific law as it applies to light.

Students use media resources and an in-class investigation to explore the types of energy within different types of systems. They also use the formulas for kinetic and potential energy to examine the path of a projectile.

In this video segment adapted from ZOOM, the cast builds a suspension bridge from a couple of chairs, some cardboard, and rope.

In this interactive activity from ChemThink, learn how ionic bonds are formed and how an ionic bond structure is represented by its formula.

In this video segment adapted from NOVA scienceNOW, follow scientists in their quest to understand how stable elements are made and how to create the elusive element 114.

Are all atoms of an element the same? How can you tell one isotope from another? Use the sim to learn about isotopes and how abundance relates to the average atomic mass of an element.

This issue of the free online magazine, Beyond Penguins and Polar Bears, examines physical science concepts, such as heat, conductors, and insulation, and applies this knowledge to the animals and people in the Arctic and Antarctica.

This problem provides an interesting context to consolidate addition of fractions and requires students to develop and analyze different strategies and explain their findings. Students are asked to find a general method for expressing unit fractions (fractions which have numerators of one) as the sum of two different unit fractions. They also explore whether all unit fractions can be written like this in more than one way. The Teachers' Notes page offers rationale, suggestions for implementation, discussion questions, and ideas for extension and support.
