Cicada Life Cycle - Sir David Attenborough's Life in the Undergrowth
Did you know that cicadas lie beneath the earth for up to 17 years, then venture above ground as a massive group to shed their larvae shells, sprout wings, and sing for a mate? Attenborough is the narrator for this BBC documentary video, which is suitable for older elementary, middle school, and high school students.

Bianca Goes Where the Wind Blows
In this segment from Cyberchase, Bianca gives her niece Mikaela a kite for her birthday. Bianca is determined to find the best place to fly it. To help with their search, Bianca creates a wind gauge that measures how hard the wind blows. After taking wind gauge readings in different spots around the park, they are able to find a spot where the kite soars beautifully. Run time 03:25.
Physics with Mr. Noon: Electric Current, Part 2
The instructor gives more classroom demonstrations dealing with electric current, voltage, resistance, and Ohm's Law. The classroom is dark because the instructor is using a projector in a darkened room.
Voltage
This video ten minute video explores voltage. The video primarily differentiates electric potential and electrical potential energy. Electric
potential energy is the amount of work that is needed to move that
particle from one spot to another. The video features animation and a spokesperson.
Circuits (Part 1)
Introduction to electricity, circuits, current and resistance. This video, starts with a black screen because the instructor, in his conversational tone, uses it as a 'chalkboard.' Instructor uses different colors for clarification. Run time 11:39.
Circuits (Part 2)
Resistors in series. This video, starts with a black screen because the instructor, in his conversational tone, uses it as a 'chalkboard.' Instructor uses different colors for clarification. Run time 11:08.
Electric Circuits Design and analysis of currents flowing in series and parallel circuits of resistors and capacitors depend not only on the celebrated laws of Ohm and Kirchhoff, but also on the less celebrated work of Charles Wheatstone.
What Is the Formula to Calculate Resistance?
The formula to calculate resistance is voltage, or potential
difference, divided by current equals resistance in ohms. Calculate the
resistance created by a power supply with instructions from a math and
science teacher in this free video on science formulas.
How to Build a Basic Electronic Circuit
The components within an electronic circuit are much lower, in
terms of energy consumption, than an electrical circuit. Find out how to use a transistor to create an integrated circuit with help from a
science teacher in this video.
