The purpose of the "Yummy Gummy Lab" was to observe the effects of __________ on a gummy bear. *

My hypothesis was that the gummy bear left in plain water will *

My hypothesis was that the gummy bear left in salt water will *

My hypothesis was that the gummy bear left in no water will *

Choose the number that reflects the order in which the procedure for the experiment took place *

Think about the steps we took to complete this lab experiment

Label the beakers as "water," "salt water"

After some time has passed take the gummy bear out of their solutions and notate measurements again

Place a gummy bear on each beaker

Measure the 3 gummy bears and notate their before measurements (height, width, thickness, color, etc)

Fill 100 mL of each solution into their labeled beaker

Analyze if there was a difference in measurement

Write a conclusion based on the results of the experiment

Conclusion

Choose the best answer according to your homework

Why did it happen? It has to do with a process called_______. *

Imagine the gummy bear is a real living thing. It would be made up of tiny, living units called_________. *

Each cell is surrounded by a _________ that protects the cell by keeping the cell parts inside and keeping other things outside. *

While it stops most things, _________ can pass through it. *

We call the membrane ________________, because it decides what comes in and out. *

Osmosis is a kind of diffusion. When diffusion occurs, molecules move from a 1)______ concentration towards a 2)________ concentration of water. *

1) lower, 2) higher

1) higher, 2) lower

1) inside, 2) outside

1) outside, 2) inside

If the water outside the cell has LESS water than inside, water will move from the _1)_______ of the cell to the _2)_______. *

1) lower, 2) higher

1) higher, 2) lower

1) inside, 2) outside

1) outside, 2) inside

That is what happened to the Gummy Bear in the __1)____. The water had to move out of the Gummy Bear to ___2)_____ the concentration of water. The Gummy Bear became ___3)____ with less water to fill it up. *

The opposite happened to the Gummy Bear in the plain water. Water moved from the __1)___ of the Gummy Bear to the __2)___ to even out the concentration of water. As more and more cells gained water, the Gummy Bear became larger as more water filled it up *

So why did the Gummy Bear in ______ get as big as the Gummy bear in plain water? Since there was sugar in the water AND in the Gummy Bear, the water didn't have to move as much to "even out" the concentration. *

What does this have to do with me? Osmosis works the same way for your cells as it does the Gummy Bear. When you sweat a lot, you are ______ water. *

Osmosis takes over and starts to pull water out of your cells, which is not a good thing. Now that water left your cells, the concentration of salt in your cell has______. *

It is important to drink LOTS of water if you are sweating a lot. _________ would occur again and balance out the water to keep you healthy. *
