The illustration shows two kinds of matter. Which BEST explains how pizza differs from milk?
Pizza is a suspension, and milk is a solution.
Both are solutions; pizza’s components can be seen, and milk’s components cannot be seen.
Pizza is a mixture, and milk is a compound.
Both are mixtures; pizza is heterogeneous, and milk is homogeneous.
Students were asked to create and sort models of classified matter into pure substances and mixtures. Which statement correctly explains how the molecules in the illustration could be sorted based on their characteristics?
Sample X is the only example of a pure substance, because it is the only sample with only one type of element.
Samples V and Y are mixtures, because they are made of multiple substances that are not chemically combined.
Samples U and W are classified as mixtures, because the molecules are chemically combined in these samples.
Samples U, V, and W are examples of pure substances, because there are multiple unique substances in the samples.

Students were asked to create and sort models of classified matter into pure substances and mixtures. Which statement correctly explains how the molecules in the illustration could be sorted based on their characteristics?
Kala wanted to classify common household materials as pure substances and mixtures. She collected as many things from around her house as possible and made two lists. Kala’s friend thinks that she made a mistake.
What change can Kala make to her list that will correct her mistake?
Ellie was comparing samples of substances to determine if they were a pure substance or a mixture. Ellie classified Samples A and B as mixtures and Sample C as a pure substance.
Is Ellie’s classification correct? Why or why not?
An unknown substance is a liquid and is red in color.
How can you determine if the unknown is a mixture or a pure substance?
In the water cycle, water molecules absorb thermal energy from the Sun, causing them to evaporate from lakes and oceans and rise into the atmosphere. Eventually, they form clouds and then precipitation.
Which statement describes the activity of the water molecules in this process?
On chilly mornings, water vapor may cool to form frost on grass and windows. It goes directly from a gas to a solid through a process called deposition.
Which sequence of boxes represents the change in the movement of particles of water vapor as it deposits?
The diagram represents water molecules at 0 ⁰C.
How should the model be changed to show these water molecules at -5 ⁰C?
Alex’s teacher showed him a model of gas particles in a sealed container.
How should Alex change the model to show the particles of this gas at a higher temperature?
You are planning and carrying out investigations to distinguish between chemical and physical properties of sugar.
Which of the following techniques demonstrates a chemical property of sugar and why?
Which state of matter has the highest density and the largest amount of chemical potential energy?
Relate the changes in molecular motion of particles as they change from solid to liquid to gas.
Elaborate on the reason(s) that matter is said to move even as in a solid state
Which of these would best describe the outcome of increasing the kinetic energy of the molecules in the above picture?
From the list below, determine which properties are for compounds.
I. It takes a large amount of energy to separates the elements of a compound.
II. The proportions of the elements in a compound are always fixed.
III. It is easy to separate the elements of a compound.
IV. The elements/components of a compound do not retain their individual properties.
