In this video segment, the ZOOM cast demonstrates how to use cabbage juice to find out if a solution is an acid or a base.
The synthesis and reactivity of atomic hydrogen
In this hands-on OLogy activity, kids learn about matter by building their own models of carbon out of pipe cleaners, wire, and clay. The activity begins with a kid-friendly introduction to matter, elements, and atoms. The illustrated, step-by-step directions show kids how to use the information about carbon on the Periodic Table to create a mobile that shows the element's basic structure. A PDF version of the Periodic Table, along with a kid-friendly overview of how to read it, is also included.
Overview of how the periodic table was developed and information on its breakdown into different blocks.
What is there to know about the periodic table? Why is it important? Why does it appear in nearly every science lecture room and labs? Is it just a portrait of an aspect of chemistry or does it serve a useful purpose? Why is the name periodic appropriate? Why is the table arranged in such a way? What are the important features of the table? Does it give order to the approximately 120 known elements?
Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Then play a game to test your ideas!
Submitted as part of the California Learning Resource Network (CLRN) Phase 3 Digital Textbook Initiative (CA DTI3), CK-12 Foundation’s Chemistry - Second Edition FlexBook covers the full course of chemistry topics taught in high school. This digital textbook was reviewed for its alignment with California content standards. The 25 chapters cover measurement in chemistry, matter and energy, the atomic theory, Bohr model of the atom, chemical periodicity, behavior of gases, acid and bases, stoichometry, covalent bonds and formulas, electron configuration of atoms.

This is a lab activity where the students group the given elements as metals, nonmetals or metalloids.
Students learn about the periodic table and how pervasive the elements are in our daily lives. After reviewing the table organization and facts about the first 20 elements, they play an element identification game. They also learn that engineers incorporate these elements into the design of new products and processes. Acting as computer and animation engineers, students creatively express their new knowledge by creating a superhero character based on of the elements they now know so well.
This is a comprehensive science textbook for Grade 10. You can download or read it on-line on your mobile phone, computer or iPad. Every chapter comes with video lessons and explanations which help bring the ideas and concepts to life. Summary presentations at the end of every chapter offer an overview of the content covered, with key points highlighted for easy revision. Topics covered are: skills for science, classification of matter, states of matter, kinetic molecular theory, the atom, the periodic table, chemical bonding, transverse pulses, transverse waves, longitudinal waves, sound, electromagnetic radiation, particles, compounds, physical and chemical change, representing chemical change, magnetism, electrostatics, electric circuits, reactions in aqueous solution, quantitive aspects of chemical change, vectors and scalars, motion in one direction, mechanical energy, the hydrosphere. This book is based upon the original Free High School Science Text series.
This survey chemistry course is designed to introduce students to the world of chemistry. In this course, we will study chemistry from the ground up, learning the basics of the atom and its behavior. We will apply this knowledge to understand the chemical properties of matter and the changes and reactions that take place in all types of matter. Upon successful completion of this course, students will be able to: Define the general term 'chemistry.' Distinguish between the physical and chemical properties of matter. Distinguish between mixtures and pure substances. Describe the arrangement of the periodic table. Perform mathematical operations involving significant figures. Convert measurements into scientific notation. Explain the law of conservation of mass, the law of definite composition, and the law of multiple proportions. Summarize the essential points of Dalton's atomic theory. Define the term 'atom.' Describe electron configurations. Draw Lewis structures for molecules. Name ionic and covalent compounds using the rules for nomenclature of inorganic compounds. Explain the relationship between enthalpy change and a reaction's tendency to occur.

This interactive activity from the American Chemical Society presents the properties and electron configurations for all the elements in the periodic table. Discover patterns by plotting the elements' properties according to their place in the table.
Inorganic chemistry is a division of chemistry that studies metals, their compounds, and their reactivity. Metal atoms can be bound to other metal atoms in alloys or metal clusters, to nonmetal elements in crystalline rocks, or to small organic molecules, such as a cyclopentadienyl anion in ferrocene. These metal atoms can also be part of large biological molecules, as in the case of iron in hemoglobin (oxygen-carrier protein in the blood). Upon successful completion of this course, students will be able to: Describe nuclear charge and calculate effective nuclear charge in terms of Slater's rules; Demonstrate an understanding of trends in the periodic table; Describe the bonding between atoms in terms of valence bond theory; Describe inorganic structures by using valence shell electron pair repulsion theory; Identify the nomenclature rules of coordination compounds; Demonstrate an understanding of crystal structures, lattice energies, and different types of unit cells; Explain the electronic structure of solids, the concept of band gap energy, and how this band gap determines the electronic properties (insulator, conductor, and semiconductor) of solid materials; Describe general trends in the reactivity of elements within Groups I through VII.
