Measure the Giraffe
Choose a building or climbable pole that is at least 20 feet in height (high enough to measure a giraffe).
Lay the heavy end of a measuring tape on the ground beside the building or pole. Lay a heavy object such as a rock on it.
Stand a ladder beside the building. Climb the ladder or pole to a height of 20 feet, pulling the measuring tape with you.
Climb down, marking each foot from 20 feet to 5 feet with a marker. Mark each foot with a long line, each inch with a short line. Write the numbers for each foot beside the foot markings. If you do not need as accurate a measurement, you can just mark the foot and half-foot intervals.
Record the Growth
Download a free spreadsheet application such as OpenOffice.org, Calc, Gnumeric or log on to Google Spreadsheets. Create a new file. Save the file with the name of your giraffe and the date he or she was born.
Write the years, starting from the year you are in now to 30 years from now, across the top row with each year in a separate cell. Write the months from January to December down the first column, starting from the second row.
Copy and paste the text you just entered into additional spreadsheet pages if you have more than one giraffe.
Record the giraffe's height in the corresponding cell for the month and year you measured him or her, starting at birth.
