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. observation 2 if silicone o - ring gaskets are exposed to below freezing temperatures, then their integrity will be damaged. hypothesis 3 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 (- 80°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, - 80°c) for 30 minutes. experiment 7 observe gasket integrity throughout the length of exposure. draw conclusions 6 analyze data 4 scientific question share results 5

Explanation:

The statements describe steps in the scientific method. The first is an observation about O - ring gasket failures at different temperatures. The second is a hypothesis about damage at below - freezing temperatures. The third is another hypothesis about cracking at a specific temperature. The fourth is a scientific question. The fifth is data from an experiment. The sixth is a step in the scientific method to draw conclusions. The seventh is the experiment itself.
