Atomic Structure.
๐ฏ Your mission
Predict it first. Then prove yourself right (or wrong).
โก The twist
Mixing two safe things doesn't always make a safe thing.
Mind = Blown
๐ง Hot water can freeze faster than cold water under the right conditions. Nobody fully understands why.
Make a hypothesis first
Predict: will the mixture get hotter, colder, or stay the same?
What You'll Learn
Symbiosis is a close relationship between two different species. In mutualism, both benefit; in parasitism, one benefits while the other is harmed; in commensalism, one benefits and the other is unaffected.
Key Words
- germination
- pollination
- photosynthesis
Materials Needed
- paper towels

Steps
Look at the vocabulary words and write a definition for each in your own words.
Design a controlled experiment: grow plants under different light conditions (full sun, partial shade, no light). Water equally and measure growth daily for one week.
Use your senses (except taste) to describe what you notice.
Write a summary of your findings in 3-5 sentences.
