It's not just for kids, it's for everyone. If you are looking for basic chemistry help and information, stay on this site. We have information on matter, atoms, elements, the periodic table, reactions, and biochemistry. If you're not sure what to click, try our site map that lists all of the topics on the site. If you get lost in all of the information, use the search function at the top or bottom of each page.
The computer will give you a list of chemical symbols and a list of chemical names. Choose the chemical name that each chemical symbol represents. Press the 'Check my answers!' button after you have made your choices.
This site offers games for students in math, science, the elements, reading comprehension and some just for fun!
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.
Welcome to It's Elemental - Balancing Act! The computer will give you a number of incomplete chemical equations. Balance the chemical equations by selecting coefficients from the pull-down menus. Once you think the equation is balanced, press the 'Check my answer!' button. Have fun and good luck!
A lesson for every single element on the period table. Created by the Periodic Videos team using the TED-Ed platform.
Each lesson has a video and it guide you through learning about it. Resources include:
WATCH
THINK (Questions)
DISCUSS (Discussion Questions)
AND FINALLY (Which is different and depends on the element)
You can also customize the lesson and share what you've made.
Students will model the atomic structure of common elements found in soils, determine an atom's valence electrons, draw Lewis electron dot diagrams, and discuss the basic principles of element bonding.
The following file contains the assets (or resources) to accompany the Sask DLC Grade 9 Science. Please note that this is not the content of the course, but the assets used to support and deliver it. The files are organized in a zipped folder. You can download it and extract the files. Links are also provided to other materials like videos and other suggested resources.
This Crash Course Kids video reviews how substances can be organized into groups according to their various properties.
Proof: Any subspace basis has same number of elements. Created by Sal Khan.
Check out these great video/curricular resources for Grade 7. The ROVER videos all indicate the curriculum outcomes that they address.
ROVER (Recommended Online Video Education Resources) is a video streaming service for Saskatchewan teachers and students in the PreK-12 education system. It is managed and maintained by the Saskatchewan Ministry of Education. ROVER is a video-on-demand service that provides teachers and students with the convenience of immediate access to streamed, educational videos that support curricula.
This site also offers all of the curriculum documents for all grade levels.
If you are unable to access the site, it may be because a Saskatchewan Ministry of Education Blackboard login is required. All students have an Edonline account, so contact your child's school or the Ministry of Education’s Support Desk at 1-866-933-8333 or email at stans@gov.sk.ca for login information. Your child's student number will be required.
Science assessment rubrics for every grade from Grade 1-9, for each unit.
Add different salts to water, then watch them dissolve and achieve a dynamic equilibrium with solid precipitate. Compare the number of ions in solution for highly soluble NaCl to other slightly soluble salts. Relate the charges on ions to the number of ions in the formula of a salt. Calculate Ksp values.
What exactly can we tell about an unknown substance by it's properties. We already know that a substance is matter that’s made of one kind of atom or molecule, and that has specific properties and that some substances are elements, which means they can’t be broken down into other substances through physical changes or chemical reactions. We also know that we can group substances and elements by their properties. We know that metals have high reflectivity and magnetivity. What else do we know about metals?
