In this interactive activity from the ZOOM Web site, search for chemistry clues and experiment with acids and bases in a virtual kitchen.

Practical lab into the chemical reaction between calcium carbide and water and the resulting ignition of acetylene gas.

How do you know if a chemical equation is balanced? What can you change to balance an equation? Play a game to test your ideas!

The Biology course is a first-year course in biology at the high school level and involves the scientific study of living organisms. The course considers the interactions among the vast number of organisms that inhabit planet Earth. It presents the basic form and function of these organisms, from cells to organ systems, from simple viruses to complex humans. It delves into interactions between organisms, and between an organism and its environment. It also looks into how biotechnology is used to improve our health and daily lives.

- Understand the form and function of microorganisms
- Understand the form and function of plants
- Understand the form and function of animals
- Understand the workings of human biological systems
- Understand biology as it relates to the Earth's environment

A 90 minute laboratory experiment utilizing observations and reasoning regarding the Law of Conservation of Matter and Energy.

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.

Life as an emergent property of networks of chemical reactions involving proteins and nucleic acids. Mathematical theories of metabolism, gene regulation, signal transduction, chemotaxis, excitability, motility, mitosis, development, and immunity. Applications to directed molecular evolution, DNA computing, and metabolic and genetic engineering.

Students will compare ingredients in two different pancake recipes, then taste the difference. We will talk about the chemical reaction that happened when the recipes are mixed and why there are bubbles in the pancakes.

CK-12 Chemistry Đ Second Edition covers: Scientific Method; Matter; Atomic Structure; Elements & Their Properties; Chemical Reactions; Stoichiometry; Chemical Kinetics; Physical States of Matter; Thermodynamics; Nuclear & Organic Chemistry.

The resources selected for this publication will help your students understand chemistry at work, using examples that will spark their interest. A basic understanding of chemistry concepts and terminology will prepare them for more abstract studies.

Students will study how temp and concentration affect reaction rates and then design a procedure to get the reaction to occur in a specified amount of time.

Find out about the chemistry of candy and how sugar reacts at different temperatures to become fudge, caramel, lollipops, and more in this interactive activity adapted from the Exploratorium.

In this interactive activity adapted from Iowa State University, design and carry out an experiment: dissolve salts in water, see how different ionic compounds produce different reactions, and observe the resulting changes in temperature.

In these videos adapted from the Journal of Chemical Education, observe how a material that is usually hard to ignite becomes very flammable when its particles are suspended in air.

This module focuses on the launch and propulsion of the Genesis spacecraft. Students will become familiar with how rockets are launched, learn how and why specific rockets are chosen for varying payloads, learn about the history of rocketry, and work with variables that might affect the performance of a launch vehicle. They will work in teams to test a single variable involved in launching a rocket and learn the variables involved with constructing and launching a water rocket. Each activity includes a teacher's guide and students handouts. Video and audio clips are provided.

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: atomic combinations, energy and bonding, intermolecular forces, solutions and solubility, atomic nuclei, thermal properties and ideal gases, quantitative aspects of chemical change, energy changes in chemical reactions, types of reactions, the lithosphere, the atmosphere, vectors, force, momentum, impulse, geometrical optics, lenses, telescopes, microscopes, human eye, longitudinal waves, sound, sound waves, physics of music, electrostatics, electromagnetism, electric circuits, electronic properties of matter, conduction. This book is based upon the original Free High School Science Text series.

This lab activity is designed to have students use their knowledge of balancing and identifying chemcial reactions and apply it in a fun and interesting way!

This is the first semester in a two-semester introductory course focused on current theories of structure and mechanism in organic chemistry, their historical development, and their basis in experimental observation. The course is open to freshmen with excellent preparation in chemistry and physics, and it aims to develop both taste for original science and intellectual skills necessary for creative research.

During this activity students build a plastic pipette rocket. The first concept will to learn how igniting varying mixtures of hydrogen and oxygen will affect how far the rocket will fly. Second students will observe and manipulate variables to better understand the fundamental chemistry concepts: principles of combustion reactions, kinetics, stoichiometry, gas mixtures, rocketry, and different types of chemical reactions. Finally, students will assess their own understanding of these chemistry concepts by investigating how NASA scientists launch real rockets into space. One follow-up activity would be to investigate and collect data on a launching a heavier object at the school football field.
