Atmosphere and Heat Transfer Summative Remediation Sheet

Name ______Period _____

*The items on this remediation sheet are drawn from the data analysis of the test taken on 3/12/18. Data showed that S6E4a, atmospheric layers, specifically temperature and 36E4b, unequal heating from day to nightwere the weakest areas. Students will be retaking a very similar test when they retake Wednesday March 14. This sheet is meant to serve as a supplement to warm ups, the Science notebook, the prior formative and summative assessment to help students prepare. It should not be the only tool of preparation.

Student Reflection Original Grade ____
There are a variety of factors that could impact how well a student performs when tested. Please answer the questions below honestly in order to help make future assessments a success.
Did I meet expectations on this assessment?
If you did, explain what you did to prepare that you feel contributed the most to your success.
If not, explain why. Were there barriers to your preparation? What would you do differently in the future that could eliminate the barriers? What might you do to increase your chances of success on future assessments?

ATMOSPHERE – Read the passage below:

The atmosphere can be divided into four layers based on temperature variations. The layer closest to the Earth is called the troposphere. Above this layer is the stratosphere, followed by the mesosphere, then the thermosphere.

Temperature variations in the four layers are due to the way solar energy is absorbed as it moves downward through the atmosphere. The Earth’s surface is the primary absorber of solar energy. Some of this energy is reradiated by the Earth as heat, which warms the over lying troposphere. The global average temperature in the troposphere rapidly decreases with altitude until the tropopause, the boundary between the troposphere and the stratosphere.

The temperature begins to increase with altitude in the stratosphere. This warming is caused by a form of oxygen called ozone (O3) absorbing ultraviolet radiation from the sun. Ozone protects us from most of the sun’s ultraviolet radiation, which can cause cancer, genetic mutations, and sunburn. Scientists are concerned that human activity is contributing to a decrease in stratospheric ozone. Nitric oxide, which is the exhaust of high-flying jets, and chlorofluorocarbons (CFCs), which are used as refrigerants, may contribute to ozone depletion.

At the stratopause, the temperature stops increasing with altitude. The overlying mesosphere does not absorb solar radiation, so the temperature decreases with altitude. At the mesopause, the temperature begins to increase with altitude, and this trend continues in the thermosphere. Here solar radiation first hits the Earth’s atmosphere and heats it. Because the atmosphere is so thin, a thermometer cannot measure the temperature accurately and special instruments are needed.

As altitude increases in each layer, what happens to the temperature in the:

Troposphere / Stratosphere / Mesosphere / Thermosphere

(Not in the passage) As altitude increases in each layer, what happens to the air pressure in the:

Troposphere / Stratosphere / Mesosphere / Thermosphere

HEAT TRANSFER:

When comparing the soil and water heating lab data with all classes, which substance heated the fastest; soil or water? Which substance cooled the fastest; soil or water?

If it is Noon at the beach, would the beach and water be heating or cooling?

If it is Midnight at the beach, would the beach and water be heating or cooling?

Using the answers from above, which is correct? Why?

A scientist is recording the temperatures of coastal sand and ocean water.

Which of these tablesmost likelyshows his observations?

Parent Acknowledgement
I have reviewed my child’s reflection and understand that he/she will be allowed to retake the Atmosphere and Unequal Heating Summative on March 14th. Times are available before school at 8:10am. Students who can’t come in early or stay late will be afforded the opportunity to take the retake during class on that day. Those students who do so will be responsible for making up any missed work.
