Conduct an experiment to see how the temperature in a cup changes with the amount of sugar dissolved in the cup. Make sure a teacher pours the hot water for you!
Create a table with the headings – amount of sugar (mg), amount of sugar (grams), starting temperature (C), final temperature (degrees C), time (seconds).
Make a graph (either drawn or using Create-a-Graph) to show how the temperature changes with time for each mass of sugar. What does the graph tell you? Are the slopes linear? What is the domain and range of your data?
Using letters to describe relationships
And here is a list of investigations you can conduct :
What is the relationship between the number of lines and the number of stars?
What is the relationship between the number of dots and the number of pentagons?
What is the relationship between the number of lines and the width?
What is the relationship between the number of lines and the length of the cross arms?
What is the relationship between the number of lines and the number of triangles?
