2. Place the Dino is a container of water or other liquid. Make sure the Dino is covered

with the liquid. Wait one hour or longer.

3. Remove the Dino and pat him dry with paper towels. Place the Dino on the same

graph paper but below the first drawing. Trace, shade or color as you did before. Count

the shaded squares and record. Record the time.

4. Put the Dino back into the water (or liquid) and wait for another hour. Repeat these

steps for 24 hours or one day. You may record every few hours and still get good data.

5. After the last tracing, add ¼ cup of table salt to the water (or liquid) in the container

that held the Dino. Stir to mix the salt into the water or liquid. Place the Dino into the

salt solution. Notice that he floats! Place a spoon or other object on the Dino to keep the

Dino under the salt solution. Wait for one hour and repeat measurements as you did

before. Keep soaking and recording until the Dino reaches a size where there is no

longer any change.

Conclusions:

1. Your data is the number of squares on your graph paper. Measure the size of a square

in centimeters with a ruler. One square is equal to __________ square centimeter. This

is a measurement of area or length x width.

2. How many square centimeters did your Dino grow in water in one day? __________

3. Using the data of size in square centimeters and time, make a line or bar graph to show

the changes in area per hour for the WATER OR OTHER LIQUID measurements. The

time is the independent variable and placed on the horizontal axis.

4. Make another graph of the salt solution measurements.

5. Did you prove your hypothesis correct? ____ Explain. _________________________

_______________________________________________________________________

6. How did the growth of Dino compare to the observations you made while he was in a

salt solution? Did he behave the same or differently? Explain.

________________________________________________________________________

7. Based on your observations, explain the movement of water for the Dino in water and

for the Dino in salt water. Answer on a separate sheet of paper.
