Christina has a glass of water. Michael has a fruit juice drink. Both drinks are at room temperature, and both students add ice to their drink's. Condensation begins to on the outside of Christina's glass before Michael's. How can they state their observations as a problem to design an experiment.
A) What is condensation?
B) How does ice cause condensation to form in water?
C) Does the temperature of the air influence condensation?
D) Does the type of liquid influence the rate at which condensation forms?
This is for the people who got on now.
Not even going to guess?
Let me give you some hints:
What variables are the same for each?
B) does not address the variable
They know what condensation is.
Does the temperature of the air influence condensation?
To design an experiment based on their observations, Christina and Michael can state their observations as the following problems:
1) Problem A: What is condensation?
- This problem seeks to understand the process of condensation and its causes.
2) Problem B: How does ice cause condensation to form in water?
- This problem aims to investigate how the presence of ice leads to condensation forming on the outside of Christina's glass but not on Michael's fruit juice drink.
3) Problem C: Does the temperature of the air influence condensation?
- This problem focuses on exploring whether the temperature of the surrounding air affects the formation of condensation on Christina's glass compared to Michael's drink.
4) Problem D: Does the type of liquid influence the rate at which condensation forms?
- This problem intends to examine whether the type of liquid (water or fruit juice) influences the speed at which condensation occurs on the respective containers.
To design an experiment based on their observations, Christina and Michael can state their observations as a problem in the following ways:
A) What is condensation?
- This observation suggests exploring the phenomenon of condensation and understanding its mechanism. The experiment could involve studying the process of condensation by introducing a known quantity of water vapor into a controlled environment and observing the formation of condensation.
B) How does ice cause condensation to form in water?
- This observation implies investigating the relationship between ice and the formation of condensation in water. The experiment could involve comparing the presence or absence of ice in multiple containers of water at the same initial temperature and examining the rate and amount of condensation that forms on the outside of each container.
C) Does the temperature of the air influence condensation?
- This observation proposes exploring the effect of air temperature on the formation of condensation. The experiment could involve placing identical containers filled with the same quantity and temperature of liquid (e.g., water or fruit juice) in two or more different environments with varying air temperatures. The amount and rate of condensation forming on the containers could then be measured and compared.
D) Does the type of liquid influence the rate at which condensation forms?
- This observation suggests investigating whether different liquids result in varying rates of condensation formation. The experiment could involve comparing the condensation formation on the outside of containers filled with different liquids (such as water, fruit juice, or other liquids at room temperature) under the same environmental conditions (temperature, humidity) and time intervals. The amount and rate of condensation could be observed and compared.
By designing experiments based on these observations, Christina and Michael can gather data to further understand the factors influencing condensation and test their assumptions.
