Information Processing.

๐ŸŽฏ Your mission

Predict it first. Then prove yourself right (or wrong).

โšก The twist

Nature loves to surprise the careful watcher.

๐Ÿคฏ

Mind = Blown

๐Ÿ”ฌ The more you look, the more nature shows you.

๐Ÿ”ฎ

Make a hypothesis first

Before you start: write down what you think will happen, and why.

What You'll Learn

Red blood cells carry oxygen using a protein called hemoglobin. White blood cells fight infection. Platelets help form blood clots to stop bleeding when you get a cut.
