Question

your team writes a report of your findings and posts it to an aerospace - engineering forum.
silicone o - ring gaskets exposed to cold temperatures seem to fail more often than those exposed to warm temperatures.
if silicone o - ring gaskets are exposed to below freezing temperatures, then their integrity will be damaged.
silicone o - ring gaskets will crack with exposure to temperatures below - 76°f (- 60°c).
do silicone o - ring gaskets crack under freezing temperatures?
o - ring gaskets maintain their integrity up to - 76°f (- 60°c), however, the gaskets exposed to - 130°f (- 90°c) showed structural damage after five minutes of exposure.
place o - ring silicone gaskets in temperatures of 32°f, - 22°f, - 76°f, - 130°f (0°c, - 30°c, - 60°c, - 90°c) for 30 minutes.

Explanation:

Step1: Identify the scientific question

The question "Do silicone O - ring gaskets crack under freezing temperatures?" is the scientific question.

Step2: Identify the hypothesis

"If silicone O - ring gaskets are exposed to below freezing temperatures, then their integrity will be damaged." is the hypothesis.

Step3: Identify the experiment

"Place O - ring silicone gaskets in temperatures of 32°F, - 22°F, - 76°F, - 130°F (0°C, - 30°C, - 60°C, - 90°C) for 30 minutes. Observe gasket integrity throughout the length of exposure." is the experiment.

Step4: Identify the observation

"Silicone O - ring gaskets exposed to cold temperatures seem to fail more often than those exposed to warm temperatures. Silicone O - ring gaskets will crack with exposure to temperatures below - 76°F (- 60°C). O - ring gaskets maintain their integrity up to - 76°F (- 60°C), however, the gaskets exposed to - 130°F (- 90°C) showed structural damage after five minutes of exposure." are the observations.

Step5: Identify sharing of results

"Your team writes a report of your findings and posts it to an aerospace engineering forum." is sharing the results.

Step6: Analyze data

No specific data analysis steps are given in the text, but the observations are part of the data that would be analyzed to draw conclusions.

Step7: Draw conclusions

No specific conclusion is given in the text.

Answer:

Scientific Question: Do silicone O - ring gaskets crack under freezing temperatures?
Hypothesis: If silicone O - ring gaskets are exposed to below freezing temperatures, then their integrity will be damaged.
Experiment: Place O - ring silicone gaskets in temperatures of 32°F, - 22°F, - 76°F, - 130°F (0°C, - 30°C, - 60°C, - 90°C) for 30 minutes. Observe gasket integrity throughout the length of exposure.
Observation: Silicone O - ring gaskets exposed to cold temperatures seem to fail more often than those exposed to warm temperatures. Silicone O - ring gaskets will crack with exposure to temperatures below - 76°F (- 60°C). O - ring gaskets maintain their integrity up to - 76°F (- 60°C), however, the gaskets exposed to - 130°F (- 90°C) showed structural damage after five minutes of exposure.
