Third graders attempt to determine the height of a telephone pole or tree without climbing to the top.

Learners experiment and discuss circuits and how they work. In this science lesson plan, students construct a telegraph machine using cardboard, wires, battery, electric tape and masking tape. They investigate what happens as the...

Students differentiate between exponential and logarithmic functions. In this algebra lesson plan, students use logarithmic properties to solve equations. They identify growth and decay of graphs.

Pupils explore the concept of code theory. In this code theory lesson, students discuss noise, error correction, Hamming distance, parity check matrices, and cyclic codes. Pupils develop these concepts through practice and discussion.

Eighth graders measure height and shadow length of other students on a sunny day and develop a ratio. They apply the ratio to other students and objects using shadows to determine height.

Students examine and discuss the Morse Code. In small groups they develop messages using Morse code and take turns decipering the messages.

Based off of the hit television show NUMB3RS, this lesson has students explore how "closely connected" a network structure is. Framed in the context of a terrorist cell, students must find which setups would allow organizations to still...
