Watch beta decay occur for a collection of nuclei or for an individual nucleus.
Starting from atoms, see how many molecules you can build. Collect your molecules and see them in 3D!
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!
Chemistry: Atoms First is a peer-reviewed, openly licensed introductory textbook produced through a collaborative publishing partnership between OpenStax and the University of Connecticut and UConn Undergraduate Student Government Association.
This title is an adaptation of the OpenStax Chemistry text and covers scope and sequence requirements of the two-semester general chemistry course. Reordered to fit an atoms first approach, this title introduces atomic and molecular structure much earlier than the traditional approach, delaying the introduction of more abstract material so students have time to acclimate to the study of chemistry. Chemistry: Atoms First also provides a basis for understanding the application of quantitative principles to the chemistry that underlies the entire course.
Crash Course Kids combines the same engaging lecture-style content delivery with animated graphics that focus on grade school science.
Topics include Earth Science, Physical Science, Biology, Geography, Engineering, and Astronomy.
These videos are amazing!
The University of Saskatchewan offers this tremendous resource that promotes the richness and diversity of the sciences, nurture curiosity and innovation, and inspire students to consider a career in science, and support teachers to provide exciting educational experiences.
Check out the great collection of video and activity resources for teachers and parents to supplement and enhance Grade 9 science learning.
Just how small are atoms? And what's inside them? The answers turn out to be astounding, even for those who think they know. This fast-paced animation uses spectacular metaphors (imagine a blueberry the size of a football stadium!) to give a visceral sense of the building blocks that make our world. A quiz, thought provoking question, and links for further study are provided to create a lesson around the 5-minute video. Educators may use the platform to easily "Flip" or create their own lesson for use with their students of any age or level.
Create a laser by pumping the chamber with a photon beam. Manage the energy states of the laser's atoms to control its output.
How did scientists figure out the structure of atoms without looking at them? Try out different models by shooting light at the atom. Check how the prediction of the model matches the experimental results.
Students will predict bond polarity using electron negativity values; indicate polarity with a polar arrow or partial charges; rank bonds in order of polarity; and predict molecular polarity using bond polarity and molecular shape.
Produce light by bombarding atoms with electrons. See how the characteristic spectra of different elements are produced, and configure your own element's energy states to produce light of different colors.
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.
When do photons, electrons, and atoms behave like particles and when do they behave like waves? Watch waves spread out and interfere as they pass through a double slit, then get detected on a screen as tiny dots. Use quantum detectors to explore how measurements change the waves and the patterns they produce on the screen.
