The Transit in Pictures

Lights, camera, action! Math educators consider how to improve their instruction by examining a model of the five-practice problem-solving model involving a movie theater. Participants examine cognitive demand in relation to problem...

While this resource does not provide problems for chemistry learners to solve, it outlines skills that they should have and concepts that they should grasp. Topics include thermodynamics, periodicity, redox equilibria, transition metals,...

Water, one of the basic needs of humans, is found in all three states of matter on Earth; no other planet—that we know of—possesses this quality. Here is a unit that allows learners to explore through experimentation what it...

With the abundance of food products we can easily access in our society today, it is easy to forget the toll this can take on our global environment. Young learners will discover how the transition to agriculture and domesticated living...

Do your part to prevent forest fires with an activity about not playing with matches. A word search prompts young rangers to fill in the blanks about the consequences of playing with matches, and a set of pictures provides spaces for...

Scientists used flame tests to identify elements long before the invention of emission spectroscopy. Young chemists observe a flame test of five metal cations in the fourth lesson of an 11-part series. Individuals then work...

Introduce your young chemists to alkali metals, alkali earth metals, transition metals, metalloids, nonmetals, halogens, and noble gasses with a presentation that explains the classes of elements and a few facts about each. 

Calculate the movement and properties of planets like professional astronomers! Scholars use Kepler's third law to find Mercury and Venus's distance from the sun. Using changes in brightness of distant stars and Kepler's third law,...

From hydrogen to ununoctium, this collection of videos has everything you need to begin teaching about the periodic table. Offering descriptions of each element and interesting experiments...

Humans have only inhabited the earth for a fraction of the time that life has existed. Young scientists explore the facts about the emergence of life on Earth with an interactive resource. While highlighting different types of life, the...
