Today the students reviewed how to create graphs to represent data. We did a PopCorn Read Aloud to review different types of graphs and what they can be used for. We also discussed how creating and using graphs helps scientist to recognize things like patterns, relationships, scale, proportion, quantity, stability, change, cause, and effect (NGSS CCCs) as well as allowing scientist to analyze and interpret data, engage in argument from evidence, and obtain, evaluate, and communicate information (NGSS SEPs).
After this, we participated in a class survey of our favorite type of dessert, created a data table, and then made a simple bar graph of the data. After we graphed this data, I showed them how they could turn their simple bar graph into a multi-bar graph by adding data from other classes. I then showed them how to create a key for this multi-bar graph. Students were told that they would be expected to create a multi-bar graph of the Life Science data chart (the one they copied into page 9) as part of their Creative Output for this assignment on page 8 of the ISN.
We then answered the questions for #1 -#2 and began creating the line graph for #3. Some classes were able to complete the line graph and answer the questions for #3 while others were not. I have provided the work completed and assigned questions #4 and #5 as homework due with ISN Check 02 on 10/04/17.
