Guilded Age 2

Read the two questions.Question 1: Is change in atmospheric CO2 levels likely to impact marine life?Question 2: Should diesel and gasoline engines compliant with CO2 emission standards be banned?Use complete sentences to explain whether both questions can be answered by science or not. Be sure to explain why for each question.

1. Yes science can help answer whether co2 levels are likely to impact marine lie. You can figure out how much co2 is in the atmosphere and figure out if marine life can handle that amount. 2. No science cannot help answer this question because its a matter of opinion.

What part of the scientific method involves drawing inferences about experimental results and determining if the collected data support the original hypothesis?

Drawing conclusions

A student wants to examine a substance without changing its identity. Which of the following properties of the substance should the student examine?

Ductility, because it can be observed by altering the shape of the substance

Which of the following cannot be tested by science?

How emotion affects the quality of a painting

Which question requires knowledge from both science and religion to answer?

How were the atoms that create all matter originally formed, and how are they are able to bond together to form compounds and molecules?

Which of the following is a property of a pure substance?

It can be chemically separated if it is a compound.

Which of these statements best explains why chemistry is testable?

It can measure data by experiments.

Which of the following happens to a molecule of an object when the object is heated?

It gains kinetic energy.

Which statement is not true about the field of science?

It is consistent and does not need to change with new discoveries.

Which of the following is a unit of volume in the metric system?

Liter

Janet observes that bubbles rise inside water when water is heated. Which of the following best names and explains the change that causes bubbles to rise?

Physical change, because heat only changes the attractions of the molecules

What type of energy does a rock resting on top of a hill have?

Potential energy

What are characteristics of reliable science?

Replicable results and empirical data

Carlos is trying to determine how music affects the growth of bean plants. He hypothesizes that classical music will cause a plant to grow at a higher rate than no music or rap music. He grows nine bean plants in similar lighting, temperature, and soil conditions. Three are exposed to classical music 24 hours a day, three are exposed to rap music 24 hours a day, and three are grown in complete silence. Carlos measures the growth of the plants every day and finds that the plants all seem to have the same rate of growth.What is missing from Carlos's scientific investigation?

Research on what other scientists have observed and investigated on this topic

Which of these is an example of a physical change?

Shredding of leaves in a machine

The solar system moves at the speed of 828,000 km/h. Tara writes the following steps to calculate this speed in decameters/second (dm/s).[1 km = 100 dm]Step 1: Divide 828,000 by 100.Step 2: Divide the result obtained in step 1 by 60.Step 3: Divide the result obtained in step 2 by 60.Step 4: Write the number obtained in step 3 with the unit dm/s.Which step is incorrect in the conversion?

Step 1

A scientist hypothesizes that the temperature at which a turtle's egg is incubated determines the sex of the offspring (whether it will be male or female). What is the independent variable?

Temperature

If a question is testable and can provide an answer based on empirical observations and reasonable logic, it can be answered with science.

True
