The Effects of Meteor Impacts

Using a chart of student test grades as an example, curious chemists learn how to calculate weighted averages. They apply this knowledge to elements on the periodic table. As practice in calculating average atomic masses, learners...

Where does the mass for a growing tree come from? Scholars consider a few different hypotheses and guess which is correct. They then analyze data from different experiments to understand which concepts science supports.

If you've ever wondered why clouds sometimes look so different, look no further than a classroom poster about cloud identification. It features pictures of clouds at high, mid, and low levels of altitude, as well as the name of each...

Should we be afraid of a large asteroid impact on Earth today? Young scientists estimate the size and composition of an asteroid similar to the one that caused the K-T mass extinction. They apply algebraic formulas to answer questions...

Dinosaurs owe their destiny to an asteroid. What are the chances humans will meet the same fate? A fascinating video lesson considers the probability of an asteroid colliding with the earth while taking into account variations in...

Students identify the relationship between kinetic energy, mass, and velocity. Then they explain and graph the relationship between kinetic energy and mass. Students also predict the impact of objects of different mass and velocity on...

Many variables impact your body mass, not just diet and exercise. Scholars collect and study data about body mass to better understand the complexity of a sensitive topic. They learn about leptin deficiency, the hypothalamus, and more.

A science lesson from the International Space Station is sure to be a hit. The video explains mass versus weight and the impact gravity has, or doesn't have, on each. The included worksheet encourages space scientists to research what it...

Solve the ultimate who dunnit mystery: the death of the dinosaurs. Viewers watch an engaging video that describes how the asteroid impact hypothesis came to fruition and the evidence supporting it. The video also explains how life...

How high will it bounce? Groups determine the height different balls bounce off of different surfaces. By performing the necessary calculations, they determine the initial and final momentum of the balls. The included worksheet provides...
