Florida Sunshine State Standard Benchmark: SC.H.3.2.4:

The student understands that science, technology, and society are interwoven and interdependent.

Additional Florida Sunshine State Standard Benchmarks:

SC.D.1.2.2: The student knows that 75% of the surface of the Earth is covered by water.

SC.D.1.2.4: The student knows that the surface of the Earth is in a continuous state of change as waves, weather, and shifts of the land constantly change and produce many new features.

background knowledge
BACKGROUND KNOWLEDGE
  • EXPLAIN:

Earth has been called the water planet. The average radius of the earth is 3,963 miles. The surface area of the earth is 197,259,000 square miles. Approximately 75% of the earth is covered by water. Oceans actually make up 97.2% of the water found on earth. Although the oceans are connected, different parts have different names: Atlantic, Pacific, Arctic, and Indian. The Pacific Ocean is the largest. All the water that has ever been available to our planet is on or in the earth right now. The percent of total area that each continent and ocean makes up can be determined by randomly selecting locations on the globe.

background knowledge1
BACKGROUND KNOWLEDGE

In this experiment, it is very important that we record data as we perform multiple trials to ensure validity of our results. It is very important to take very detailed notes as you conduct your experiments. In addition to your data, record your observations as you perform the experiment. Write down any problems that occur, anything you do that is different than planned, ideas that come to mind, or interesting occurrences. Be on the lookout for the unexpected. Your observations will be useful when you analyze your data and draw conclusions. It is very important that you follow your procedure carefully to ensure fair, scientific testing.

background knowledge2
BACKGROUND KNOWLEDGE

While testing, record all data immediately. Be accurate and exact as you observe, measure, describe, count, or photograph. The results will be more convincing and valid if you repeat the experiment as many times as possible. For example, an experiment that uses ten plants will give more valid results than one that tested only one or two plants. Testing and measuring the distance a car rolled down a ramp twenty times would be more valid than testing it only three times. Understand that an experiment must be repeated many times and yield consistent results before the results can be accepted.

Objective:

I can record data from the experiment to determine that approximately 75% of the Earth’s surface is covered by water.

purpose
Purpose:

To apply the scientific process in order to record, analyze, and communicate results to determine that 75% of the Earth’s surface is made up of water.

slide13

Materials:

  • 1 Inflatable Globe
  • Chart paper
  • Blue and green crayons
  • Water, Water Everywhere! Chart
slide14

HYPOTHESIS

(write in your own as an IF…..THEN…. statement)

  • If I randomly toss a globe back and forth to a partner, then my finger will land on water 75% of the time.
slide15

Procedure

1. Brainstorm how to determine the percent of the earth

covered by each of the continents using only an

inflatable globe.

2. Using the chart – record your predictions as to what

percent of the earth that continent or ocean covers.

3. Sit in a circle with your group and toss the globe with 2

hands to someone in your group 20 times.

4. Tally on the chart to record your results if the catcher’s

pointer right finger lands on water AND on what

continent or ocean

5. Repeat this process 3 times.

6. Total your results on the chart.

explain
Explain:

Explain how your results compare to this chart? Were your predictions accurate?

results conclusion
Results/Conclusion:
  • From the data recorded, what can you determine about the surface of the Earth?

elaborate
Elaborate:

Todd wanted to determine the amount of water that could be saved with a water-saving nozzle on his family shower. Each day for one month, each family member plugged the bathtub drain and measured the water level after taking a shower using the water-saving nozzle.

Part A What could Todd do to improve his experiment to show how much water his family saved?

Part B What additional benefits to the environment would there be to using the water-saving nozzle?

evaluate
Evaluate:

Cities have water purification programs to keep drinking water free from bacteria and other pollutants. How does this help people living in these cities?

A. It eliminates filters from factories.

B. It produces large amounts of water.

C. It helps people by cleaning the air they breathe.

D. It helps people by making the water safer to use.
