Features 13 core lab activities covering the fundamental concepts of physiology, ecology, plant systems and more
Use a force sensor to investigate and observe changes in the muscular movement of bones during a prolonged period of sustained exertion.
In this activity, students investigate and observe changes in the muscular movement of bones during a prolonged period of sustained exertion while they:
- Measure changes in force applied by their thumbs over a period of time
- Learn that the human organism has systems for digestion, respiration, reproduction, circulation, excretion, movement, control, coordination, and protection from disease, and that these systems interact with one another
- Learn that all organisms must be able to obtain and use resources, grow, reproduce, and maintain stable internal conditions while living in a constantly changing external environment
- Gain skills and confidence in using a scientific measurement tool, the force sensor, as well as the graphing capacity of a computer to represent and analyze data
Students gain experience conducting the following procedures:
- Setting up the equipment to measure force versus time
- Applying a push to the force sensor for 60 seconds without watching the force graph
- Applying a push to the force sensor for 60 seconds while watching the force graph
- Repeating the procedure for all lab group members
- Using math skills to interpret the force versus time data
Sensors / Equipment Used:
Designed to measure both pulling and pushing forces. Uses range from collisions to tug-of-war.
The Associated Bundle:
This bundle contains the probeware needed to perform all 49 lab activities in the Middle School Science through Inquiry lab manual.
