In this module, students engage in a visual demonstration on the causes & effects of air pollutants on air quality and kinesthetic activities on particulate matter & visibility.
Watch alpha particles escape from a polonium nucleus, causing radioactive alpha decay. See how random decay times relate to the half life.
Having students follow animal tracks (even just people, dogs, or squirrels) and investigating how tracks are made is a fun and exciting way to develop critical thinking, measurement, and graphing skills.
In this lesson, students explore the importance of albedo (or reflectivity) to penguins and the surfaces they inhabit and learn how penguin colonies may be mapped using satellites.
In this middle school and high school unit, students engage with 360�� virtual reality tours, authentic Arctic datasets, and app-based labs to construct models and explanations for the unit driving question, "Why might the Arctic be warming twice as fast as the rest of the world?"
In this lesson, students investigate whether other parts of the world are changing and getting hotter just like Colorado.
Create your own shapes using colorful blocks and explore the relationship between perimeter and area. Compare the area and perimeter of two shapes side-by-side. Challenge yourself in the game screen to build shapes or find the area of funky figures. Try to collect lots of stars!
Build rectangles of various sizes and relate multiplication to area. Discover new strategies for multiplying algebraic expressions. Use the game screen to test your multiplication and factoring skills!
Build rectangles of various sizes and relate multiplication to area. Partition a rectangle into two areas to discover the distributive property.
Build rectangles of various sizes and relate multiplication to area. Discover new strategies for multiplying large numbers. Use the game screen to test your problem solving strategies!
Explore the interactions between various combinations of two atoms. Turn on the force arrows to see either the total force acting on the atoms or the individual attractive and repulsive forces. Try the "Adjustable Attraction" atom to see how changing the parameters affects the interaction.
Experiment with a helium balloon, a hot air balloon, or a rigid sphere filled with different gases. Discover what makes some balloons float and others sink.
Why does a balloon stick to your sweater? Rub a balloon on a sweater, then let go of the balloon and it flies over and sticks to the sweater. View the charges in the sweater, balloons, and the wall.
Explore the origin of energy bands in crystals of atoms. The structure of these bands determines how materials conduct electricity.
Look inside a battery to see how it works. Select the battery voltage and little stick figures move charges from one end of the battery to the other. A voltmeter tells you the resulting battery voltage.
Watch beta decay occur for a collection of nuclei or for an individual nucleus.
Our goal is to present the key observations and unifying concepts upon which modern biology is based; it is not a survey of all biology! Once understood, these foundational observations and concepts should enable you to approach any biological process, from disease to kindness, from a scientific perspective. To understand biological systems we need to consider them from two complementary perspectives; how they came to be (the historic, that is, evolutionary) and how their structures, traits, and behaviors are produced (the mechanistic, that is, the physicochemical)
Build fractions from shapes and numbers to earn stars in this fractions game or explore in the Fractions Lab. Challenge yourself on any level you like. Try to collect lots of stars!
When will objects float and when will they sink? Learn how buoyancy works with blocks. Arrows show the applied forces, and you can modify the properties of the blocks and the fluid.
During this module, students take a virtual mobile lab drive with scientists to investigate and learn about atmospheric carbon gases, their sources, and impacts on air quality.
