Science Bowl Round 1

Amanda is examining a piece of granite rock with a hand lens. She knows that igneous rocks were formed in a specific way. Which is the process of the formation of igneous rock?

• It is always formed when molten rock cools.

• It is always formed by weathering and erosion.

• It is always formed when heat and pressure change other rocks.

• It is always formed with crushed animal shells, bone and teeth.

Select all of the following that describes an example of a material undergoing a chemical change to become another material with different characteristics.

• When water boils, it turns into vapor, which is a gas.

• Iron turns to rust when it is exposed to oxygen.

• When marshmallows are roasted over a fire.

• Gold can be spread out very thin to cover a large area.

• Stomach digesting food.

The force of gravity appears to attract all objects equally, regardless of mass. Which of the following demonstrates this idea?

• Two cars traveling along the road at the same speed in opposite directions.

• A rubber ball will bounce much higher than a wooden ball, even if they weigh the same.

• Magnets can both repel and attract each other, depending on how they come into contact.

• A bowling ball and a marble will fall to the ground at the same rate when someone drops them.

The students in Mrs. Shapiro's class are experimenting to see whether different types of soil affect the growth of plants. They plant three seedlings in sandy soil, three more in clay soil and three more in topsoil. They give each plant the same amount of water and place the plants in a sunny window as shown in the picture. After two weeks, the students observe that the plants in the topsoil grew best. Which of the following is evidence on which the students will base their conclusions?

• observations and drawings of the seeds

• description of the procedures for the investigation

• predictions the students made before the investigation

• height of the plants growing in each of the different soils

Around seven o'clock one evening, Deion observed a pattern of stars, called Orion, in the night sky. Three hours later, he went outside to show his parents that same patterns of stars. What would he notice about the pattern of stars after three hours?

• The pattern of stars would appear to be in the same place in the sky.

• The pattern would be smaller because the stars moved closer together.

• The pattern of stars would appear to have moved together across the sky.

• The pattern would change because each star would have moved in a different direction.

Annabelle and Jose are building a complete circuit for their science inquiry in class. They want the lightbulb to turn on an off so they install a switch. The light switch can be used to open and close their circuit. Given the information above, which statement below must be true about using a switch in a circuit?

• The switch must use a conductor such as rubber to open the circuit and light the bulb.

• The switch must use an insulator such as rubber to close the circuit and light the bulb.

• The switch must use an insulator such as copper to open the circuit and light the bulb.

• The switch must use a conductor such as copper to close the circuit and light the bulb.

Janice found two seashells when she went to the beach. They appear to be almost the same size, but they have different shapes. How could she figure out if their volume is the same?

• Fill each seashell with water to see if they hold the same amount.

• Find the mass of each seashell on a balance to see if they have the same mass.

• Measure the length of each seashell with a measuring tape to see if they are the same length.

• Drop each shell into a graduated cylinder with water to see if they raise the water level equally.

Todd can throw a baseball from the outfield all the way back to home plate. Why does he have to move his arm in order to make the ball fly all that way?

• He has to get the ball high enough in the air so the air can support it.

• The ball's energy can only be released if he lets it go above the ground.

• Moving his arm makes the ball's own energy take it in the right direction.

• He has to transfer some of his muscle's energy to the ball to make it move.
