Introduction
Today you are going to explore different resources to learn more about how information travels through the human body.
Please visit the resources on the next pages and be ready to answer question afterwards about what you explored.

Task
Task 1:
Take a pretest to give me information about your background knowledge (click HERE or go to https://goo.gl/forms/J8g7wpJMJtREegv63)
Task 2:
Watch this video about the basics of a neuron (or visit http://viewpure.com/HZh0A-lWSmY?start=0&end=0
Task 3:
Play the interactive “Mad Mad Neuron” game
Task 4:
Visit the “Bitesize: The Nervous System” resource pages (use pages 1, 2 and 3)
Task 5:
Play the Baseball Reaction Time game
Process
Answer the following questions after you have explored the different resources:
- What are neurons?
- Summarize- How are neurons different from other cells you may have seen before?
- What is a synapse? What happens there?
- What are 3 types of neurons?
- Where might sensory receptors be found? List examples.
- List examples of 2 sense organs, and what stimuli the receptors in these sense organs are sensitive to.
- What are reflex actions and how do they work?
- Why is it a benefit to humans to have reflex actions?
- Compare and contrast reflex actions and the way our body's stimulus/ response pathway works normally.
- Write a quick summary of how a batter hits a fastball using terms we have learned so far.
- We are going to design a simple experiment to test a person's reaction time using a falling meter stick. Would it be more accurate to measure their reaction time by timing how fast the test subject catches the falling meter stick, or by measuring how far the meter stick falls and converting the distance to time using a reference chart? Explain.
Evaluation
After you have completed all tasks and answered the study questions, take this post test:
