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.

A work in progress, CK-12 Chemistry Teacher's Edition supports its Chemistry book covering: Matter; Atomic Structure; The Elements; Stoichiometry; Chemical Kinetics; Physical States of Matter; Thermodynamics; Nuclear and Organic Chemistry.

This activity provides a demonstration and lab exploration of one of the main "building blocks" of the periodic table of elements: chlorine. During the lab, students compare physical and chemical properties of chlorine compounds.

Students will be able to differentiate between pure substances and mixtures, as well as elements, compounds, homogeneous mixtures, and heterogeneous mixtures.

This is a fun interactive way to learn about mixtures and compounds as well as test how much you know about them. Complete the crossword to see how much you know about compounds and mixtures.

This Introductory Chemistry textbook was developed by the Chemistry faculty at Montgomery College, and provided by Professor Patricia Takahara. The book is meant for students with very little or no background in chemistry. Concepts here are presented at a very basic level in order to provide the foundation for college-level general chemistry. This book is used in Introductory Chemistry, a non-credit, preparatory course at Montgomery College (Maryland).

This is a POGIL activity geared for general chemistry students. The activity guides students through the process of determining how ionic and binary compounds are named as well as inorganic acids.

This investigation is to help reinforce the idea that a mixture can be taken apart by physical means. It will be set up as a contest in which students will have 3 hours of class to separate as much pure substance as they can. These will be broken into percentages based on purity and the amount they have been able to separate. There is no procedure written so students have a completely open and inquiry based activity.

This activity is an extension activity following a unit study on mixtures and solution. Students will use variables to create a unique cola formula and present their findings.

This lesson plan introduces the properties of mixtures and solutions. A class demonstration gives the students the opportunity to compare and contrast the physical characteristics of a few simple mixtures and solutions. Students discuss the separation of mixtures and solutions back into their original components as well as different engineering applications of mixtures and solutions.

Through three lessons and their four associated activities, students are introduced to concepts related to mixtures and solutions. Students consider how mixtures and solutions and atoms and molecules can influence new technologies developed by engineers. To begin, students explore the fundamentals of atoms and their structures. The building blocks of matter (protons, electrons, neutrons) are covered in detail. The next lesson examines the properties of elements and the periodic table one method of organization for the elements. The concepts of physical and chemical properties are also reviewed. Finally, the last lesson introduces the properties of mixtures and solutions. A comparison of different mixtures and solutions, their properties and their separation qualities are explored.

Small molecules are chemicals that can interact with proteins to affect their functions. Learn about the structure and biological functions of various small molecules like sugar and caffeine. Also featured on the HHMI DVD, Scanning Life's Matrix: Genes, Proteins, and Small Molecules. Available free from HHMI.

Students are challenged to use computer-aided design (CAD) software to create “complete” 3D-printed molecule models that take into consideration bond angles and lone-pair positioning. To begin, they explore two interactive digital simulations: “build a molecule” and “molecule shapes.” This aids them in comparing and contrasting existing molecular modeling approaches—ball-and-stick, space-filling, and valence shell electron pair repulsion (VSEPR)—so as to understand their benefits and limitations. In order to complete a worksheet that requires them to draw Lewis dot structures, they determine the characteristics and geometries (valence electrons, polar bonds, shape type, bond angles and overall polarity) of 12 molecules. They also use molecular model kits. These explorations and exercises prepare them to design and 3D print their own models to most accurately depict molecules. Pre/Post quizzes, a step-by-step Blender 3D software tutorial handout and a worksheet are provided.

This quick-lab provides a concrete experience with crystal formation from saturated salt solutions that can help students make solubility problems more relevant to their experience.

This activity is a lab where students will be working with chemical changes and reactions. It's a simple activity that can be done with household items.

Learn about properties of matter through engaging, bitesize animated videos. There are many videos organised into these chapters: solids liquids and gases, elements compounds and mixtures, atomic structure, periodic table, ionic bonding, covalent bonding and metallic bonding.

This is a quiz on mixtures and compounds to see how much you know. Review readings and other assignments to prepare for this quiz.

This is a lab activity where students will investigate solubility or miscibility of eight substances with water.

The Chemistry Capstone Essay is a way to introduce or assess students' knowledge and understanding of a variety of science texts and their understanding of chemical theories and applications taught during the year. Students demonstrate knowledge by having to be concise and distill down complex ideas and connections from a variety of different texts.
