Hobos
In the Garden: Reading Temperature Graphs
Having
a new tool to carry out experiments is like playing with a new toy. During
the tulip experiment some Journey North classrooms signed up with iScience
to use a new tool, the Hobo Data Recorder in their gardens. Maybe these
batterypowered temperature recorders can help us learn about the physiology
of tulip bulbs.
Who knows, we may even learn what temperatures are necessary for tulips
to emerge and bloom!
Use
Data to Solve Garden Location Puzzle
Analyzing experimental data is difficult and often takes extra time and
effort before a level of understanding is reached. Scientists study data
for clues to answer questions. What questions do you have when you look
at the 2 graphs? What statements can you make about this data from one
of our Garden Sites? Let’s begin by practicing using mathematical
terms to describe what we see.

Can
You Communicate in Mathese?
The process of translating graphic pictures of the data encourages us
to learn and use mathematical vocabulary. Understanding terms like axis,
horizontal, vertical, range, outlier, etc. are essential for communicating
about the data. Try answering these questions as you practice using mathematical
terms.
 Find the
x axis on each graph. What is represented along this horizontal line?
 How many
times is each date represented along the x axis?
 Find
the y axis. What is represented along this vertical line?
 What
is the lowest temperature on the y axis on each graph?
 What
is the high and low temperature on each graph? Find it and calculate
the temperature range.
 Which
graph has the largest range in temperatures?
How
to Conclude
After answering the questions write a paragraph about each of the graphs.
The data for each was recorded in the same garden. Do you want to know
more? Include any questions you have.
Maybe temperature
recorders can help us learn more about the physiology of tulip bulbs.
Who knows, we may even learn about what happens to make tulips emerge
and bloom!
National
Science Education Standards
Science
as Inquiry
Use
data to conduct a reasonable explanation. (K4)
Use math
in all aspects of scientific inquiry. (58)
Simple instruments,
such as magnifiers, thermometers, and rulers, provide more information
than scientists obtain using only their senses. (K4)
Physical
Science
Objects have observable properties, including size, weight, shape, color,
temperature, and the ability to react with other substances. Those properties
can be measured using tools, such as rulers, balances, and thermometers.
