Brief Description/Unit Goal
This Internet-based collaborative
project will allow students to share information about water usage with
other students from around the country and the world. Based on data collected
by their household members and their classmates, students will determine
the average amount of water used by one person in a day. They will compare
this to the average amount of water used per person per day in other parts
of the world. The students will locate the web page provided and navigate
the web site to answer the questions in Down The Drain.
The first lesson, highlighted
here, is: Lesson 1a How Much in a Gallon? In this lesson, students
will learn to use their computer efficiently and effectively to research
from a web site.

Science
Unit objective: After
locating the website to answer the question, How Much is a Gallon? the
students will navigate the website formulate a hypothesis, control and
manipulate variables with water flow formula, devise and conduct the experiment,
to predict an outcomes, compare and analyze results, and defend their conclusions.
Lesson Objectives:
-
In this lesson 1a, the students
will use an online calculator to convert their gallon hypothesis to liters
using http://www.calculator.com
-
After navigating the website the
students will complete the accompanying worksheet with 100% accuracy.
Pre-Requisite Technology Skills
The following skills are necessary
to successfully complete this lesson:
-
The students will be able to turn
on the computer independently.
-
The students will be able to find
and click on Netscape Communicator.

Materials
Accommodations for Special Needs
-
Special Education Students: Print
the word gallon on the gallon container and Liter on the liter container.
-
Gifted: Explore the other calculators
on the calculator page.
-
SEI: Print the word gallon on
the gallon container and Liter on the liter container. Teach the words
calculator, scroll, click before the lesson.
Procedures
1. Anticipatory Set: Show the
students a gallon container. Ask the following questions:
-
What is this?
-
How much water would this container
hold? (Accept gallon or liter)
-
How different is a gallon from
a Liter? Which is bigger? Who uses these measurements? Where have you seen
people use these measures?
2. State today’s objective. A
major part of science is the scientific method. We just finished a science
fair project and you did very well. Now we are going to begin a science
experiment using the computer tools to help us with your new investigation.
We are going to a captivating website Down the Drain. It asks us to determine
How much water we use. Today will start with the gallon/liter comparison.
Later we will use the computer to actually conduct a scientific experiment.
These lessons will help you learn to use your computer efficiently and
effectively. We will eventually answer the question How much water do we
really use? Let’s complete the first part of this scientific investigation
called How Much In a Gallon? The computer can help us answer this question
and show use how to convert gallons to Liters.
3. There are two worksheets
to help us keep track of our data. We’ll begin with the worksheet 1a: How
Much In a Gallon?
4. Hand out the worksheet,
Worksheet 1a: How Much In a Gallon?
5. Read the worksheet together
and give the students time to record their hypothesis for each question.
6. Comparing Gallons and Liters
Here in the U.S. we still
use gallons to measure the quantity of many liquids. However, that is starting
to change. Can you think of anything that is measured in liters instead
of gallons? Yes, gasoline in Mexico and liters of Coke or Pepsi in the
US.
7. Now that you have your guesses,
each is called a hypothesis. Let’s convert our gallons to liters. The computer
can help.
8. Go to the Down The drain
website: http://www.k12science.org/curriculum/drainproj/
9. Click on the left side
of the screen on the Reference
Material section.
10. Scroll to calculator.com
11. Click on the orange unit
converter.
12. Scroll to volume. Type
in your gallon estimates and click calculate.
13. View and record the data
on your worksheet Lesson 1a: How Much in a Gallon?
Assessment
1. Worksheet 1a: How Much in
a Gallon?
2. Using a student checklist,
the teacher will record the student’s ability to access the website and
follow the directions to the calculator and convert the volume measures.
