Information Processing.
🎯 Your mission
Set it up. Test it. Be amazed.
⚡ The twist
Nature loves to surprise the careful watcher.
Mind = Blown
🔬 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.
What You'll Learn
The skin is the body's largest organ. It protects against germs, helps regulate body temperature, and contains nerve endings that detect touch, pressure, pain, and temperature.
Key Words
Tap a word to see its definition.
Materials Needed
- cotton balls
Safety First
- Have an adult check your set-up before you start, and tidy everything away afterwards.
Steps
Look at the vocabulary words and write a definition for each in your own words.
Map your taste zones: dip cotton swabs in salty, sweet, sour, and bitter solutions. Touch different areas of your tongue and record where each taste is strongest.
Compare the before and after states.
Write your conclusion: did the results match your hypothesis? What would you change next time?
