10/28/15 Date:10/28/15Topic:Hyper/Hypo/Iso (tonic)Page # ___ Use the reading on your desk to determine if the cells below are in a hypertonic, hypotonic, or isotonic solution. #1#2#3 Note: Bath time wrinkles is NOT osmosis!!

Today in Room 326… HW: Complete all calculations (if not already complete) and write full Trend Analysis (last page of lab) CONTENT OBJ: SW identify solutions as iso, hypo, or hypertonic based on the look of the cell LANG. OBJ: SW describe in writing the difference between iso, hypo, or hypertonic solutions ANNOUNCEMENTS: Good time yesterday! Every Tues/Thurs AGENDA: Reading & Identify solutions Hypo/Hyper/Iso Notes Hypo/Hyper/Iso worksheet Gummy Bear Lab Day 2 Date:10/28/15Topic:Hyper/Hypo/Iso(tonic)Page # ___

Sugar Dust Explosion

Hyper, Hypo, Iso (Tonic)* Hyper(tonic) = higher concentration of solute compared to surroundings Cells will shrink Hypo(tonic) = lower concentration of solute compared to surroundings Cell will swell Iso(tonic) = equal concentration of solute compared to surroundings Cells won’t change

Hypo/Hyper/Iso worksheet Ms. Gately- check everyone’s homework from yesterday AND today, and check the lab if not already!

Gummy Bear Connection Gummy bears in water  What should happen? Gummy bears in salty water  What should happen? You will see for yourself!

Gummy Bear Lab Day 2

Volume & Density Volume = l x w x h Density = mass / volume % change = (Day 1 / Day 2) x 100 Do the calculations!
