Conclusions

They’re a bit tricky

How did you do?

Look at the conclusion for the Bubble Gum experiment we did yesterday.

Determine which criteria you met and which you need some work on.

You will use this information to answer the following questions.

Your responses will not be scored.

Let’s Practice! Use the data table to answer the following questions

The effect of the Water Temperature (°C) on the Dissolving Time (s) of sugar

Water Temperature(°C)

Dissolving Time (s)

Trial 1 Trial 2 Trial 3 Average

10 °C 60 66 66 64

40 °C 42 41 43 42

80 °C 18 22 20 20

Investigative Question: How does the temperature of water affect the time it takes sugar to dissolve in the water?

A. The temperature does affect the time it takes to dissolve the sugar

B. The temperature does not affect the time it takes to dissolve the sugar.

C. As the temperature increases the time to dissolve decreases.

D. As the temperature increases the time to dissolve also increases.

How does the temp affect the amount of time it takes to dissolve sugar?

25%A. Therefore, as the water temperature

increases, the dissolving time decreases.B. Therefore, as the water temperature

increases by 70 degrees the dissolving time decreases.

C. Therefore, as the water temperature increases by 50oC the dissolving time decreases by 22 seconds.

D. Therefore, as the water temperature increases by 70oC the dissolving time decreases by 44 seconds.

10 °C 60 66 66 64

40 °C 42 41 43 42

80 °C 18 22 20 20

Which of the following best supports your conclusion

80 – 10 = 70 degree increase

64 – 20 = 44 second decrease

Therefore, as the temperature increases by 70 degrees the time decreases by 44 seconds.
