Lake Michigan Trip
Look at Me!
Testing the Waters
The air was cold, so I wasn't too keen on placing my feet in the water, but my sisters were brave enough to, so I did too.
I was in for two seconds and I wanted out. The water was freezing! I didn't understand how my sisters could stay in there for so long, just sloshing around happily.
I didn't understand why they would make their toes numb... But at least I wasn't cold.
Testing the Waters
Connection to Science #1
While traveling, we rode in gas fueled vehicle.
The fuel in the car powered the engine. There are four phases of the Combustion cycle that are used to keep the car in motion. The cycles repeat of and over, making the car stay in motion. The first is intake. During this phase the intake valves open while the piston pushes itself downward. This brings gas and air to the engine. The second phase is all about compression. The piston moves up and gas and air get pushed into a smaller space where it can cause a bigger explosion to push the car forward. The third phase is combustion. The spark plug ignites, causing the gas to explode. The explosion forces the piston to get pushed down. The fourth and last phase is exhaust. The exhaust valve opens and empties the leftover gas that was made by the explosion. The gas moves to the catalytic converter, then the muffler, and finally exits he tailpipe.
Connection to Science #2
The Prevailing Westerlies push all of the warm water off of Wisconsin's coast and into Michigan's. The water has to be replaced with something other than warm water(because it was pushed to Michigan's coast), so it gets replaced with cold water. Therefore the water is colder on Wisconsin's than the water than on Michigan's coast.
Why don't we have more evironmentally friendly items fueling our cars?
How do electric cars work compared to gas powered cars?
When the warm water is replaced with cold water, does the water at the bottom of the lake get colder?
