Dan wants to see how sugar and sand mix with water. He adds 5 grams of sugar and 5 grams of sand to 100 mL of water. He stirs the mixture thoroughly. Dan then pours the mixture through filter paper into another beaker. The diagram shows how filtering is completed using filter paper and a funnel. After Dan filters the mixture using the filter paper and funnel, which statement should be correct?

• Both the sugar and the sand are collected by and found on the filter paper.

• Both the sugar and the sand are found in the water collected in the beaker.

• The sand is found in the water collected in the beaker, and the sugar is collected by and found on the filter paper.

• The sugar is found in the water collected in the beaker, and the sand is collected by and found on the filter paper.

Which solution of sugar and water is the most concentrated?

• one scoop sugar in 500 mL of water

• one scoop of sugar in 1,000 mL of water

• two scoops of sugar in 500 mL of water

• two scoops of sugar in 1,000 mL of water

A student draws a picture of soup. What could the student change in the picture to show that the soup is a mixture?

• The student could draw a napkin near the soup to show that it is a liquid that can spill.

• The student could draw a spoon in the soup to show it has been mixed.

• The student could draw a placemat under the bowl to show that it is hot.

• The student could draw different vegetables in the soup to show it has different parts.

Denise has four bowling balls with different colors and masses. She records the mass of each ball in a table. Denise rolls each ball with the same force on the same surface and records the distances the balls travel in five seconds. Which statement represents an accurate inference about the motion of the balls?

• The pink ball travels a shorter distance in 5 s than the red ball.

• The red ball travels a shorter distance in 5 s than the brown ball.

• The green ball travels a shorter distance in 5 s than the pink ball.

• The brown ball travels a shorter distance in 5 s than the green ball.

Analyze the diagram that shows two objects and their corresponding forces. Which object will experience the fastest change in speed, and why?

• Object A; it is larger.

• Object A; it has a greater force applied.

• Object B; it is flatter.

• Object B; it has a greater force applied.

A student added 20 g of baking soda to a plastic bag containing 20 mL of vinegar and immediately sealed the bag. The student observed the vinegar and baking soda reacted to release a gas, which caused the bag to expand. What happened to the total mass of the substances in the sealed bag after the reaction?

• The total mass stayed the same.

• The total mass decreased.

• The total mass increased.

• The bag absorbed some of the mass.

• B. Mercury, Mars, Venus, Earth, Uranus, Neptune, Saturn, Jupiter

• C. Jupiter, Saturn, Neptune, Uranus, Earth, Venus, Mars, Mercury

• D. Neptune, Uranus, Saturn, Jupiter, Mars, Earth, Venus, Mercury

What inference can be made from the table?

• A. Inner planets are larger in size and denser compared to outer planets.

• B. Inner planets are smaller in size and denser compared to outer planets.

• C. Outer planets are heavier in mass and smaller in size compared to inner planets.

• D. Outer planets are lighter in mass and smaller in size compared to inner planets.

Compared to the Sun, all other stars look like points of light in the night sky because the stars

• are much smaller than the Sun.

• are much farther away than the Sun.

• give off different colors than the Sun.

• give off much less light than the Sun.
