Going through phases

What did you do?

We observed the different phases and collected data.

What tools did you use?
Thermometer, beaker, hot plate, safety googles, protection gloves, iPad.

What was the procedure for this investigation?
1: We put the icecubes in the beaker and placed it on the hot plate (hot plate was on 4)

2: We put the thermometer in the beaker and recorded temperature.

3: Every 4 minutes we recorded qualitative and quantitative data with the thermometer.

4: Slowly the icecubes turned into liquid, and then when we set the hot plate to its highest rate, the water turned  into gas.

What does the data tell you? Answer the questions in part A & B

A. Investigation part I (Solid – Liquid phase change)
How phases changes throughout a short activity.

When did you notice a change in temperature?

When the liquid turned into gas, the temperature got higher.

What did you observe about the temperature of the water over time once the ice was completely melted?

After the icecubes got melted, the water wasn’t as cold as the icecubes, so it was higher.

Why did the temperature of the water stop rising?

According to our data table, the temperature of the water continued rising.

B. Investigation part II (Liquid – Gas phase change)

1. What was added to the water in the beaker on the hot plate that caused the temperature to change?

We were adding heat to the water in the beaker to change the temperature.

2. Describe the temperature of the water while it was being heated to the point of evaporation.

The temperature got higher and higher and the water started bobbling.

3. Did the temperature reach boiling point before or after the water began to evaporate?
It reached boiling point before and while it began to evaporate.

Sources of error:

What are some reasons that your data/ results may not be accurate?
Some more thinking:
We may have seen wrong on the thermometer.

1. What if water only was in solid form? How would it effect our bodies?
Because our bodies contains liquid, it would be hard.

2. What if metals were only available in liquid form? How would if affect the way we travel?
It wouldn’t be possible to travel with car or plane or train or ships because all of them is made of metals. Then you would have to go by wooden boat or horse and carriage or just walk.
