a) Over the course of 4 years, the height of
Nathalie Aissi from year 2005 to year 2008 is presented. (This experiment was
conducted by Nathalie Aissi’s mother and kept for years.) (Time vs. Height)
b)
As the years go by, Nathalie’s height keeps
increasing. So what is the average rate of change in 2006?

This is funny. My aunt used to measure my brothers and I every year when we were younger. She had in her wall the height of us and we used to compare who grew faster. I would like to have done this experiment to calculate the velocity in the rate of change in each one, but my aunt painted the wall erasing all the marks.
ReplyDeleteI love the concept you used in this and how relatable it can be to everyone. Great post and you did an awesome job!
ReplyDeleteGreat choice of a an example and detailed description!
ReplyDeleteI like how you have used many scan points to display what you are doing. Furthermore, your work is easy to follow, smart idea to do it all on paper and then use a picture.
ReplyDeletenathalie,
ReplyDeletenice one! personal and relevant! a little confused because you initially said you were investigating growth for 2006, but your secant calculations show that you are looking at t = 2005. just make sure your question matches your experiment! really great job on your graphs and table and also yay for remembering to include your units in ALL of your calculations! your analysis is good and i like that you explained the IRC mathematically as well as why it makes sense in real life.
good job. =]
