4th - Water Properties Practice

Sofia placed a popsicle on a plate inside her house. After 15 minutes, it had changed into liquid juice. What does this investigation best show about how water changes state?

• Ice melts into liquid when it gains heat.

• Water boils and turns into steam when frozen.

• Ice disappears without changing temperature.

• Liquid water becomes colder when placed indoors.

A group of students wanted to measure the amount of water that collected on the outside of a bottle of cold lemonade. What tool would be best for them to use?

• Ruler

• Balance

• Graduated cylinder

• Thermometer

Jordan left a shallow dish of water on his porch in the morning. By the evening, the dish was empty even though it was never spilled. What property of water explains this change?

• The water cooled and froze into solid ice.

• The water boiled quickly and turned to steam.

• The water evaporated into a gas and mixed with the air.

• The water disappeared because it sank into the dish.

One group of students heated water until it boiled, while another group observed water freezing into ice. Why would these groups record different temperature data?

• One group observed a change from liquid to gas, and the other observed a change from liquid to solid.

• One group used a broken thermometer, and the other did not.

• Both groups measured the same change, but at different times of day.

• Both groups placed their water samples in the same location.

At Elena’s house, water is used in many ways: drinking glasses of water, keeping food cold with ice, and watching steam rise from soup on the stove. What do these examples show about water?

• A. Water is only useful when frozen as ice.

• B. Water is helpful in all of its states because each state has different properties.

• C. Steam cannot be a real form of water since it disappears.

• D. Ice and steam are not important since they don’t stay the same.

Sam placed snow in a bowl outside on a sunny day. First, the snow melted into liquid water. Later, the water was gone even though the bowl never tipped over. Which explanation best describes what happened?

• The water froze again into solid ice.

• The water melted, then evaporated into the air as gas.

• The snow soaked into the bottom of the bowl.

• The melted water stayed the same and never changed.

Students created posters about how people use water: - Poster A: “Liquid water is used for swimming, cleaning, and drinking.” - Poster B: “Solid water is used to cool drinks and preserve food.” - Poster C: “Gaseous water has no use because it is invisible.” - Poster D: “All three states of water are useful in everyday life.” Which poster contains an incorrect scientific claim, and why?

• Poster A, because water cannot be used for swimming.

• Poster B, because ice is not part of water's changes.

• Poster C, because water vapor is useful even though it cannot be seen.

• Poster D, because only liquid water has value to people.

A class designed a model showing water in three states: - Solid ice to cool fruit, - Liquid water to grow plants, - Steam to help cook vegetables. They noticed problems: the ice melted too quickly, the water flooded the soil, and the steam escaped before cooking the food. What improvement would best use scientific knowledge about water's properties?

• Insulate the ice, use drip irrigation for liquid water, and capture steam in a closed container.

• Let the ice melt naturally, pour all the water at once, and allow steam to rise freely.

• Use only liquid water for all tasks and remove the ice and steam.

• Spray mist everywhere and allow ice and steam to change on their own.
