Lessonโญ 30 XPThe Heart and Circulatory System (Part 4)
Information Processing.
๐ฏ Your mission
Learn the rule. Then catch nature using it.
โก The twist
Nature loves to surprise the careful watcher.
Mind = Blown
๐ฌ The more you look, the more nature shows you.
Make a hypothesis first
Before you start: write down what you think will happen, and why.

The circulatory system includes the heart, blood vessels, and blood. Arteries carry oxygen-rich blood away from the heart, and veins return oxygen-poor blood to the heart.
Key Words
- respiratory system
- circulatory system
Steps
Review the background information on Information Processing before starting.
Test reaction time: have a partner drop a ruler and catch it. Record the centimeter mark 10 times. Calculate your average reaction time.
Watch carefully for any changes and note the time.
Create a data table to organize your measurements.
