Week 11 Blog
What did I learn this week?
Today in lab we learned about how matter interacts with other matter in a series of experiments. There were six stations: Baking soda and vinegar, m&m's w/ water, cold soda, plunger, ice melt, and floating coke.
Baking soda and vinegar:
Some observations my group made was that the bag got cold, gas was released, and the bag expanded. One question we had was why did the bag get cold?
M&M's in water:
Observations: Colors are washing off and they are not mixing. Why did the colors not mix?
Observations: There was no condensation forming even when the soda was cold. Does consistent change in the temperature of the environment affect condensation?
Plunger:
The plunger stuck to the table but not the cardboard. Is there a difference in air pressure when it was trying to stick on the cardboard?
Ice melt:
The pot melted the ice faster while the wood struggled. Maybe the wood doesn't absorb water as well as the pot.
Floating coke:
Observations: Both small cans (diet and regular) floated. Big diet coke floated while big regular coke sunk. What does density mean? What does concentration have to do with this experiment?
Are you able to what you learned to what you already know?
I was able to properly predict some of the experiments because I've done some of them before. For example, I remember doing the baking soda and vinegar experiment. However, it was difficult to explain the scientific phenomena.
What are new or remaining questions?
How can I build on students' curiosity? What is the most important part about science pedagogy--the process/experimenting or the answers to the scientific phenomena?
