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.

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.

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.

ISOTONIC means “same strength”Under the flap, write this:• equal concentration

inside & outside• NO VISIBLE CHANGE•water moves evenly in &

outBELOW the flap, write this:• ISO = same

DRAW THIS on the flap!

HYPERTONIC means “above strength”

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!

DRAW THIS on the flap!

HYPOTONIC means “below strength”

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!

DRAW THIS on the flap!

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?
