Curated OER
The Action Potential
In this biology worksheet, learners examine the internal functions of the human body while considering the factors needed to explain the physiological reactions.

2nd Grade Physical Sciences
Second graders complete activities to measure motion and learn about the Earth's history. In this motion and Earth history lesson, 2nd graders discuss sound and complete a matching sound activity. Students then study the history of Earth...
Curated OER
Tuned in: Tuning Forks and Sine waves
Students explore the characteristics of a pure sound wave produced by a tuning fork. They use sine waves to find a curve to fit the sound wave data produced by the tuning fork. A CBL and microphone is required for this activity.
Curated OER
Ion Flow in Neurons
Student perform an experiment in which they determine the velocity of ion flow in an electrotonic potential and compare it to the velocity of action potentials. They record and analyze their results.
