2. Stations 1 – Food Coloring
No energy used
Passive transport
Diffusion

3. Station 2 – Raisins and Grapes
No energy used
Passive transport
Osmosis – water into or out of the cell

4. Station 3 – Potatoes No energy used Passive transport
Osmosis – water passing across the cell membrane
Salt water causes loss and potato becomes bendable
Tap water causes gain and potato become very sturdy

5. Station 4 – Mesh Bean Bag Active transport Energy used
Shake the beans out
Exocytosis – beans leaving the bag (exit)

6. Station 5 - Balloons No energy used Passive transport
Diffusion – air leak carrying vanilla scent outside of the balloon

7. Station 6 - Flowers No energy used Passive transport
Osmosis – water being absorbed by plant cells across the cell membrane and into the cell carrying the food coloring
