What Is Energy? Short Demos
Three short, hands-on, in-class demos expand students’ understand of energy. First, using peanuts and heat, students see how the human body burns food to make energy. Then, students create paper snake mobiles to explore how heat energy can cause motion. Finally, students determine the effect that heat energy from the sun (or a lamp) has on temperature by placing pans of water in different locations.
Global Climate Change : The Ross Ice Shelf
This video lecture explores the effects of climate change on the Ross Ice Shelf in Antarctica. Slides depict how a large iceberg fell off the Ross Ice Shelf in March 2000. The lecturer describes his expedition to the ice shelf shortly after this event. He describes dives conducted to observe the underwater ecosystems containing krill and jellyfish, and the ocean currents around the icebergs. Facts about the icebergs in Antarctica are presented, and the sensitivity of polar regions to climate is
Understanding Rational Numbers and Proportions
The three activities in this investigation center on situations involving rational numbers and proportions that students encounter at a bakery. These activities involve several important concepts of rational numbers and proportions, including partitioning a unit into equal parts, the quotient interpretation of fractions, the area model of fractions, determining fractional parts of a unit not cut into equal-sized pieces, and equivalence.
Quick take on Pythagoras and his theorem
A topic once reserved for high school geometry, the Pythagorean theorem is now part and parcel of the middle school curriculum. These resources offer visual demonstrations that can make the abstract theorem more concrete for students and lead them in analyzing the mathematical relationships involved, as recommended by the Principles and Standards for School Mathematics. The last resource offers background information on Pythagoras himself.
Look Alike Liquids
In this introductory activity, students will compare the way water and isopropyl alcohol appear on different surfaces. Through the activities in this investigation, students will see that liquids have characteristic properties that can be used to identify an unknown. There is a downloadable activity sheet that will be very helpful to educators, and will help students stay on track. An assessment sheet is also available on the activity page to keep track of students progress. There is also a step
In this activity, students use and create scatterplots based on information from a table, and compare and contrast annual rainfall in various places around the world.
This activity will help the students understand that science theories change in the face of new evidence, but those changes can be slow in coming. Students will observe how scientific theories change over time, Be introduced to the sophistication of the geocentric model and the time it took to change the theory underpinning the heliocentric model, Compare the heliocentric model to the geocentric model.
Lines of best fit using least squares
Fit a line to the data in a scatter plot using your own judgment. Then compare the least squares line of best fit.

Dreadful Memories: The Life of Sarah Ogan Gunning, 1910-1983
Teacher is advised to review content:
Born in the coalfields of eastern Kentucky, Gunning suffered a life of bitter poverty which became the fuel for dozens of moving songs about working people, the mines, and the great coal strikes of the twenties and thirties. Gunning's a cappella roots music is intercut throughout the interviews and archival footage.

Normal - Station and Gait Exam - Station Sub-exam - Patient 1
Patient is a female with no known neurological health problems who volunteered to act as a simulated patient in order to demonstrate 'normal' responses to exam techniques. She is merely a reference point for exam procedures and protocols, as well as to denote subtle signs from diagnosed patients.
Across Southwest Canada at Night
This video was taken by the crew of Expedition 30 on board the International Space Station. The sequence of shots was taken January 25, 2012 from 12:34:11 to 12:36:28 GMT, on a pass from near the border of British Columbia and Washington state, near Vancouver Island, to southern Alberta, near Calgary. The main focus of this video is the Aurora Borealis over Canada, which appears very near the space station during this short video.
Treaty of Guadalupe Hidalgo
