Can Photosynthesis Occur at Saturn?
In the 19th activity of 22, learners determine if distance from a light source affects photosynthesis. Participants capture oxygen in straws and find that the amount of water the gas displaces is proportional to the rate of photosynthesis.

Patterns and Fingerprints
Human fingerprint patterns are the result of layers of skin growing at different paces, thus causing the layers to pull on each other forming ridges. Here, groups of learners see how patterns and fingerprints assist scientists in a...
Laboratory for Atmospheric and Space Physics
The Solar Wind Tunnel
The winds of change are blowing in our very own solar system! But what makes some heavenly bodies more affected by solar winds than others? Pupils discover the concept of magnetic forces at work in space in this attractive interactive,...
Curated OER
Earth Science and Landscapes
Students examine the landscape of the Colorado Plateau. In groups, they compare and contrast the Southwest and the Colorado Plateau. They also examine the different landform formations in the area. They complete a worksheet to end the...
Curated OER
the Impact of the U.s. Supreme Court on High School Journalism.
Students study of the First Amendment, Tinker, Hazelwood and the Colorado Student Free Expression Law. They discuss the ramifications on the student press and recite their memorized First Amendment rights. They discover what can...

Women in the West
Young scholars explain how women in the West obtained the right to vote. They list at least three Colorado women, along with their major contributions, who helped shape the American West.
Vanier College
Logarithmic Function
The worksheet provides an extensive selection of questions regarding logarithm functions. Evaluating, rewriting, solving, and tons more topics are included in the worksheet.

Planetary Magnetism
What do magnetic fields look like? The best way to learn about magnetic fields is to try identifying them for yourself. Scholars will understand the importance of magnetic fields after completing this experiment. The extension activities...
PhET
Acid-Base Solutions
Learners, through watching a simulation, can manipulate various characteristics of different solutions focusing on acid-base solutions where pH, strength of solution, and concentration may be changed. Views may be at the molecular level,...
PhET
Build a Molecule
How many different molecules can you build? In a simulation, learners make molecules from given atoms. There are numerous collections from which to build three to five molecules from given kits of atoms. Scholars can also view their...
PhET
Molecule Shapes: Basics
In molecules, bonds rotate about the nucleus due to the repulsion of subatomic particles. In a simulation, learners manipulate the bonds of a molecule to meet the atoms' needs. They can then see the specific molecular shapes of five...

Measuring the Interplanetary Magnetic Field
Scientists need to figure out how to measure interplanetary magnetic fields, but the magnetic field of the spacecraft is interfering with their readings. Scholars attempt to solve the problem that has perplexed NASA scientists for years.
PhET
Isotopes and Atomic Mass
Some isotopes are unstable, or radioactive, meaning they will decay over time and turn into another isotope or stable element. In the interactive simulation, participants manipulate elements to create isotopes and gather information....
PhET
Molecule Shapes
The shape of a molecule is determined by the arrangement of atoms around the central atom and lone pairs of electrons. Scholars build models of molecules using single, double, and triple bonds. They can then see real molecules bond...
PhET
Radioactive Dating Game
Uranium 235 has a half-life of over 700 million years and is the fuel used in the atomic bomb dropped on Hiroshima, Japan. Pupils see the half-lives and decay rates of Carbon-14 and Uranium-238. They also take measurements of these two...
PhET
Reactants, Products and Leftovers
Did you know when you mix the reactants sulfur, tungsten, and silver, you get the products SWAg? The simulation begins with making sandwiches, to show pupils reactants and products of something familiar. They then can make water,...
PhET
States of Matter
Water is the only molecule on Earth that can naturally exist in all three states of matter. The interactive simulation shows different molecules changing states of matter with the addition or removal of heat. Learners then see how...
PhET
Balancing Chemical Equations
Just like the old saying goes, "What goes in must come out." This simulation allows pupils to balance chemical equations. The introduction gives three examples before scholars switch to game mode, pick their level, and continue to...
PhET
Beer's Law Lab
Beer's Law can be used to measure the concentration of certain compounds in samples of food. In the concentration simulation, particpants change and measure the concentration of different solutions by manipulating various types of...
PhET
Sugar and Salt Solutions
Ionic bonds form from electrostatic energy, allowing for higher conductivity than those seen in covalent bonds. In the simulation, learners add sugar and salt to water and see the effects on concentration and conductivity of their...
PhET
Wave on a String
The sound waves of thunder are made when lightning very quickly heats the air surrounding it, expanding faster than the speed of sound. Learners explore waves through their own movement of string or set waves to constantly oscillate....
PHET
Simplified MRI
Cancerous tissues contain more water than normal tissue, which causes the cancerous tissue to resonate longer on the screen and be seen. High school learners can see how MRIs detect tumors in someone's head. Radio transmitters emit their...
