How do you measure up? by Aaron
Everyone in our class chose a measuring project. Mine was unique, but first here’s what my classmates did. Layla travels 3 kilometers to school on the bus. The fastest speed on the ________________  was 56 kilometers per hour.Raoul used a thermometer. The high this week was 23 degrees Celsius and the low was 8.Rene brought in photographs from every one of her birthdays. The teacher said Rene was very _______________ . That means she liked her photos. She made a graph of her height on every birthday. You could see which years she grew the most. When Rene was five, she ______________ ed her photo, but the N was backwards. Charlotte found out that 22 ______________________  of the students in our school are bilingual. Cool! Isaac wanted to use a ____________  as a measure of time. He learned that sabre-tooth tigers lived 10,000 years ago. That is 100 centuries. Now for my project. Ta-da! I used photography too. I took a selfie of my bare foot with a centipede on it. Does a centipede really have 100 legs? Some kinds of centipedes have only 30 legs and others have as many as 354 legs. It’s good they don’t wear shoes, or it would take all day to tie them. By the way, the longest centipede is 25 centimeters (10 inches). It has poisonous venom that can kill a mouse. Carly read a biography of a person that lived over two thousand years ago. She learned how to measure the height of a tree without climbing it. She wrote a paragraph about how she did it (with some help from her mom). The tree was 47 meters tall. I guess that’s how you ‘measure up.
