A glass of ice water is placed on a table inside a room that is at room temperature. The ice inside the glass melts. The diagram represents the changes observed. Which piece of evidence supports the conservation of matter during the changes shown in the diagram?

• The combined mass of the glass and its contents is the same before and after the ice melts.

• The combined mass of the glass and its contents is less after the ice melts.

• The contents of the glass are wet before and after the ice melts.

• The contents of the glass are colorless before and after the ice melts.

Which of the following is a property that can be used to identify a substance?

• Color

• Smell

• Density

• All of the above

Investigate how the phases of the Moon are related to its position relative to the Earth and Sun. Create a model to demonstrate the phases and explain how your model represents this celestial phenomenon.

• Use a basketball to represent the Moon and a flashlight as the Sun, showing how light illuminates the Moon.

• Draw pictures of the Moon in different phases without showing the Sun's position.

• Use a lamp and two balls to represent the Sun and Moon, but do not simulate the Earth's position.

• Create a computer simulation that includes the Sun, Earth, and Moon, showing how the Moon's orbit affects its phases.
