1. BELL WORK: Copy and complete the concept map below:
Molecule Transport
no energy!
needs energy!
HIGH to LOW
LOW to HIGH
large molecules
water
Facilitated Diffusion
uses transport proteins
small molecules
Active Transport
Osmosis
Diffusion

2. Let’s check your eggs! Open your journal to page 17 (Egg Lab).
Send ONE person from your group to get your egg cup.
This person will pour out the vinegar and GENTLY rinse the egg.
Place the egg back into your cup and bring it back to your table.
As a group, make observations. What do you notice? How does the egg look different? How is it the same? Write what you see.
Draw a picture of what the egg looks like now.
Write a sentence in your Conclusion area about whether your hypothesis was right or wrong.

3. Now what??
Use the bottle at your table to cover the egg in syrup – just barely cover it! Don’t drown it.
With your group, create a hypothesis about what you think will happen to the egg in syrup overnight (If I put an egg in syrup, then………).
Send ONE member of your group to put the cup back on the counter.

4. Solutions Foldable Fold the top of the paper down to make a tab.
Put a THIN line of glue on your tab, then glue it to the bottom of page 16 (Transport Foldables).
Write SOLUTIONS (Osmosis) above the paper.

5. ISOTONIC means “same strength”
DRAW THIS on the flap!
Under the flap, write this:
equal concentration inside & outside
NO VISIBLE CHANGE
water moves evenly in & out
BELOW the flap, write this:
ISO = same

6. HYPERTONIC means “above strength”
DRAW THIS on the flap!
Under the flap, write this:
solute concentration HIGHER outside the cell
water moves out of the cell
CELL WILL SHRINK
BELOW the flap, write this:
HYPER = HIGH, makes the cell DRY!

7. HYPOTONIC means “below strength”
DRAW THIS on the flap!
Under the flap, write this:
solute concentration LOWER outside the cell
water moves into the cell
CELL WILL SWELL
BELOW the flap, write this:
HYPO = LOW, makes the cell GROW!

8. If the inside of a cell is 95% water, what is the concentration of water in an isotonic, hypertonic, or hypotonic solution? What is the concentration of solute in each of those cases?
