- Twenty five labs to study bones, muscles, nerves, balance, reflexes, reaction time, and muscle fatigue. Many of these labs require little setup and could be used in centers or stations. The directions are written directly to the students so they can be done independently.Six of the labs includes a o$37.00$51.00Save $14.00
How do our muscles work to produce movement? In the first activity students work with a simple model to show that muscles can only pull, they cannot push. Understanding that muscles come in pairs is a key concept when understanding a muscular system.
In the second activity, kids investigate muscle fatigue. Students squeeze simple clips or clothespins and count the number of squeezes they can do. Repeated trials change the results as their muscles fatigue. Once you have the materials, there's no prep involved. This could be set up as a station lab. In the third activity, kids use a cool model to show how muscles on one side of their hand create flexion and on the other side create extension.
- How do muscles produce movement?
- Why do muscles come in pairs?
- What happens when muscles contract over and over?
- How can you demonstrate muscle fatigue?
- How can you model muscle flexion and extension.
Topics & Concepts Addressed:
- Muscles can only pull, they cannot push
- Muscles come in pairs
- Contracting muscles may either flex or extend limbs
- Muscles become fatigued when used quickly and repetitively.
- Muscles can only pull, they cannot push.
- Muscles come in pairs
- Contracting muscles may either flex or extend limbs.
2 rulers with holes, string, brad (paper fastener), paperclips, binder clips or clothespins, seconds timer (clock or app), tag board, string, straws, hot glue
assemble the setup for the first activity or have students do this with a little assistance; building the model of the hand i takes a 20 min or more.
About 20–30 minutes per activity (90 minutes)
These labs are part of a unit of study on Bones, Muscles, & Nerves geared to a lower elementary audience (grades two and three).
Extensive teacher notes address the many questions that come up. You shouldn’t have to do outside research on this topic unless you want to.
Elementary Grades 2–3, Ages 7-9
