Watch quantum "particles" tunnel through barriers. Explore the properties of the wave functions that describe these particles.
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.
Broadcast radio waves from KPhET. Wiggle the transmitter electron manually or have it oscillate automatically. Display the field as a curve or vectors. The strip chart shows the electron positions at the transmitter and at the receiver.
Learn about different types of radiometric dating, such as carbon dating. Understand how decay and half life work to enable radiometric dating to work. Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.
Create your own sandwich and then see how many sandwiches you can make with different amounts of ingredients. Do the same with chemical reactions. See how many products you can make with different amounts of reactants. Play a game to test your understanding of reactants, products and leftovers. Can you get a perfect score on each level?
Explore what makes a reaction happen by colliding atoms and molecules. Design experiments with different reactions, concentrations, and temperatures. When are reactions reversible? What affects the rate of a reaction?
Through this lab, students are introduced to energy sciences as they explore redox reactions and how hydrogen fuel cells turn the energy released when hydrogen and oxygen are combined into electrical energy that can be read on a standard multimeter. They learn about the energy stored in bonds and how, by controlling the reaction, this energy can be turned into more or less useful forms.
Watch a reaction proceed over time. How does total energy affect a reaction rate? Vary temperature, barrier height, and potential energies. Record concentrations and time in order to extract rate coefficients. Do temperature dependent studies to extract Arrhenius parameters. This simulation is best used with teacher guidance because it presents an analogy of chemical reactions.
How did Rutherford figure out the structure of the atom without being able to see it? Simulate the famous experiment in which he disproved the Plum Pudding model of the atom by observing alpha particles bouncing off atoms and determining that they must have a small core.
This site offers a collection of hundreds of free K-12 STEM resources, from standalone models and simulations to short activities and week long sequences of curriculum materials. Filter by type of subject, activity type and grade. Searchable subjects include: physics and chemistry, life science, engineering, earth and space, and math.
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.
Students build a saltwater circuit, which is an electrical circuit that uses saltwater as part of the circuit. Students investigate the conductivity of saltwater, and develop an understanding of how the amount of salt in a solution impacts how much electrical current flows through the circuit. They learn about one real-world application of a saltwater circuit — as a desalination plant tool to test for the removal of salt from ocean water.
This site offers take-home science projects that can be completed with or without Internet access, all free of charge.
Every week Science North will provide Grade 7 teachers with a pre-recorded video and printable resource.
Teachers will be able to share these YouTube videos and resources with students weekly.
Included are classroom videos, student handouts, and offline lesson plans.
These videos and handouts can be sent to students to provide them with key concepts and activities that link to the curriculum.
Welcome to Secondary Science Implementation Support. This site from the Ministry of Education in SK has a huge collection of excellent supports for High School Science.
There are currently over 500 supports available.
Select "Support Materials" from the menu on the left.
This site houses materials developed to support teachers' implementation of secondary science courses. The Support Materials section contains materials that have been developed and refined by each of the course-specific Secondary Implementation Support teams. Teachers are free to use these materials as they wish.
Any teacher may post questions in the Discussion Board and/or share their materials. Note that copyright must be respected in all cases.
Support materials for Science 10, Health Science 20, Environmental Science 20, Physical Science 20, Chemistry 30, Physics 30, Biology 30, Earth Science 30, Computer Science 20 and Computer Science 30 have been posted.
You must be logged into Blackboard to see the supports.

Students learn how to classify materials as mixtures, elements or compounds and identify the properties of each type. The concept of separation of mixtures is also introduced since nearly every element or compound is found naturally in an impure state such as a mixture of two or more substances, and it is common that chemical engineers use separation techniques to separate mixtures into their individual components. For example, the separation of crude oil into purified hydrocarbons such as natural gas, gasoline, diesel, jet fuel and/or lubricants.
Students will design a method that applies various chemistry techniques to separate a mixture by physical means to simulate how a scientist would mitigate contamination in a stream due to run-off.
Student teams make polymers using ordinary household supplies (glue, borax, water). They experiment with the semi-solid material when warm and cold to see and feel its elastic and viscous properties. Students will begin to understand how the electrical forces between particles change as temperature or the force applied to the substance changes. Is it a solid, a liquid, or something in between? How might it be used?
Students are given a variety of materials and asked to identify each material as a solid, liquid or gas. They use their five senses ŰÓ sight, sound, smell, texture and taste ŰÓ to identify the other characteristics of each item.
This is a lesson about using light to identify the composition of an object. Learners will use a spectrograph to gather data about light sources. Using the data they‰Ûªve collected, students are able to make comparisons between different light sources and make conjectures about the composition of a mystery light source. The activity is part of Project Spectra, a science and engineering program for middle-high school students, focusing on how light is used to explore the Solar System.
