This activity is a fun way to work with scatter plots in a realistic situation. The data is from a watermelon seed spitting contest. Then, they analyze the scatterplot, identify a trend and write an explanation of the relationship between BMI and systolic blood pressure. As part of the design cycle, engineers measure, collect and analyze data. We really want students to be able to understand what a trend means on these plots. 7), Construct and interpret scatter plots for bivariate measurement data to investigate patterns of association between two quantities. Then, I give them tasks to complete like: Make a graph with a positive correlation. The activity uses some non-expendable (reusable) items such as medical sensor devices, tape measures and a scale; see the Materials List for details.

Students also draw lines of best fit and make predictions from the scatterplots. Have students brainstorm new real-world examples of positive and negative correlations in a context different than the application discussed in this lesson. 6), Describing the nature of the attribute under investigation, including how it was measured and its units of measurement. The emphasis in this lesson is to take students a little beyond the basics of Scatter Plots to explain the correlation coefficient (r) and the coefficient of determination (r squared). These measurements provide the doctor with important medical information about your health. These task cards can be used as a game, a center or station, a whole class activity, independent work, or partner practice for concepts related to scatter plots and line of best fit. TpT Digital Activity Students create a scatterplot based on data from an experiment and answer questions related to their graph. Also, the scale of both axes should be reasonable, making the data as easy to read as possible. *Vocabulary/definition guide for interactive notebook, 8.SP.2 Escape Room - Line of Best Fit & Analyzing a ScatterplotPDF AND GOOGLE FORM CODE INCLUDED. Scatter Plots and Data Activity Bundle 8th Grade $ 11.50 This Scatter Plots and Data Activity Bundle includes 6 classroom activities to support 8th-grade volume concepts. Each student gets a graph and a fun size pack of M&Ms. 2. 6), communicate mathematical ideas, reasoning, and their implications using multiple representations, including symbols, diagrams, graphs, and language as appropriate;
If you have small classes (less than 20 students), combine data from two or more classes so that the scatterplots have a sufficient number of data points. Verify that students have collected their data accurately and have calculated their BMI, blood pressure and pulse values correctly on the Student Data Sheets. (Grade
(Use a ruler.) Explain that the higher the variance (or standard deviation) value, the more the data is scattered, and the more difficult it can be to find trends. Also, they measure their blood pressures and pulse rates. The activity uses some non-expendable (reusable) items such as medical sensor devices, tape measures and a scale; see the Materials List for details. technology, engineering or math (STEM) educational standards. This line of best fit activity can be used with two groups of students - those who know how to write equations for lines and those who do not. Time Required: 2 hours 45 minutes
Or, it may be used as independent practice if students are familiar with scatter, This file includes four linear regression examples (all real-life data). 8), Knowledge gained from other fields of study has a direct effect on the development of technological products and systems. Last updated September 13, 2011. MATH MUGSHOTS are a GREAT way to review math concepts while providing some âcolorâ to math class. Calculus: Integral with adjustable bounds. Students need to be able to identify the following trends: positive correlation, negative correlation, no correlation, and need to be able to make predictions from trend lines since they will be creating and analyzing scatterplots. A student uses a wrist blood pressure sensor to measure her blood pressure and pulse rate.copyrightCopyright © 2013 RET-ENET Program, The University of Texas-Pan American. The three pieces fit together like a, This is a fantastic resource for introducing students to graphing and data representation. Scatter Plot: Shodor > Interactivate > Activities > Scatter Plot Scatter Plot: Graph ordered pairs and customize the graph title and axis labels. Although they work well enough, mercury thermometers have some problems: for instance, it takes 3-7 minutes to read your temperature, and they are made of glass. 6 -
Jul 4, 2015 - Students create a scatterplot based on data from an experiment and answer questions related to their graph. They create thermometers using simple materials and develop their own scales for measuring temperature. Students will examine eight scatter plots. I use this M & Ms scatter plot activity from Math Equals Love as an anticipatory set to reinforce positive, negative and no correlation. example. This bundle has everything you need and more to teach and assess your students on scatterplots! For these plots, expect to see positive trends: the higher the systolic blood pressure, the higher the BMI value. 8), Students will develop an understanding of the relationships among technologies and the connections between technology and other fields of study. It will be the... 2 mins 6th - 11th Math 8), Measurement and data. It is one of the best lessons that I have ever written, and I highly recommend it. Based on the popular "Two Truths and a Lie" icebreaker game. Using the class data sheets, have students create and analyze scatterplots of BMI vs. pulse rate, following the instructions on the Creating and Analyzing Scatterplots Using Technology Worksheet (see Figure 2). Scatterplots are useful to engineers when they are investigating relationships between two variables—just like we are going to be doing in this activity. 6), Giving quantitative measures of center (median and/or mean) and variability (interquartile range and/or mean absolute deviation), as well as describing any overall pattern and any striking deviations from the overall pattern with reference to the context in which the data were gathered.
