Light Optics.
🎯 Your mission
Learn the rule. Then catch nature using it.
⚡ The twist
Speed isn't the same as force. Don't mix them up.
Mind = Blown
⚡ Static electricity is the same physics as lightning, just smaller.
Make a hypothesis first
Guess: where does the energy go?
What You'll Learn
All living things share basic characteristics: they grow, reproduce, respond to their environment, and need energy to survive. Plants make their own food through photosynthesis, while animals must eat other organisms.
Key Words
- ecosystem
- producer
- consumer
Steps
Look at the vocabulary words and write a definition for each in your own words.
Create a detailed food web for a local ecosystem. Include at least 8 organisms and use arrows to show energy flow from producers to top predators.
Watch carefully for any changes and note the time.
Create a data table to organize your measurements.

Stretch Challenge
Try this in real life this week.
Time how long a small ball rolls down something, then change the slope and try again.
For the dinner table
“Show me something at home that uses this kind of energy.”
