SmartyPants Review: Q2 Benchmark Assessment

Front

What causes ice to melt in warm water?

Back

Thermal energy flows from the warm air into the colder ice, causing the molecules to move faster and change from solid to liquid.

Front

What happens to the temperature of a penny when placed in room temperature water?

Back

The heat will transfer from the penny to the water, causing the penny's temperature to decrease.

Front

What is replication in scientific research?

Back

Replication is when several scientists perform the same experiment separately and compare their results with the original experiment results.

Front

Why does a bouncing basketball not remain in motion forever?

Back

The energy is transferred to sound and heat energy as friction occurs when it hits the ground.

Front

What is the importance of repeating experiments in scientific research?

Back

Repeating experiments and having others replicate them strengthens the validity of the findings.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, which is the total kinetic energy of its particles.

Front

What is the principle of heat transfer?

Back

Heat transfer occurs when thermal energy moves from a warmer object to a cooler one until thermal equilibrium is reached.

Front

What is a hypothesis in scientific research?

Back

A hypothesis is a testable statement or prediction about the relationship between two or more variables.

Front

What is the role of friction in motion?

Back

Friction is a force that opposes motion, converting kinetic energy into heat and sound energy.

Front

What is the scientific method?

Back

The scientific method is a systematic process for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.
