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 use ball and stick models to create common compounds. Each group will need 10 Hydrogen atoms ( white ), 4 Carbon atoms (black), 2 Oxygen atoms (red), 1 nitrogen atoms (blue).

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 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.

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.

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