The kinesthetic aspect of this graphing activity captures the attention of the students who are kinesthetic learners which in turn improves effort and the level of student learning. Students can practice creating and interpreting bar graphs on these printable worksheets. Students will have one more opportunity practice graphing sample data before we progress on from our Data Analysis Unit. Have students brainstorm what equipment might be required for such a team climbing shoes, helmets, harnesses, chalk, chalk bags, carabiners, belay devices, ropes, and so on. During this practice the teacher will model the correct answer, walking through each of the problems step by step. In addition, students explain why it is important to have a good graphing window.
Step 1: Pose the following problem to your class: Do you think there is a relationship between the time studying for a test and the score earned? The worksheet contains two sections. Test Score scatterplot from the Cultivating Data Study Time vs. Cara is ordering stickers for craft supplies and she can get the stickers she needs from 2 different suppliers. The resulting line can be used to make predictions, either by finding a point on the line or by determining the formula of the line and plugging in values. How does a number line help us interpret the data? This video clip captures two students working to determine which sample graph correctly illustrates the scenario in the question. By setting up multiple stations around the room, students will maximize their instruction time by keeping students engaged throughout the entire lesson! Sometimes, no relationship is apparent between the variables, e. Note: Some equipment, such as the ropes, can be used by more than one teammate.
Within this unit students already learned about electronegativity in terms of bonding types in. Their enthusiasm was contagious and set the tone for the whole activity! The worksheet printable contains three separate worksheets about scatterplots. Test Score Table from the Cultivating Data Study Time vs. Within this lesson there are no additional resources needed. The students will receive many verbal reminders as time passes to help gauge their progress and increase their chances of completing the activity before the end of the class period. If the line were to be extended to 0 athletes, it would go through the origin. .
How do you graphically depict the data set on a number line? Conversely, in another example students will be shown a graph, they will analyze the curve, and then develop a statement best summarizing what has occurred. This is a of the answer key for the first section with how I added in partner appointments at the top and the questions I had students perform with their partners. Sample questions include reading a scenario and determining which graph best represents the situation. I also use the analogy of students in a classroom and those closest to the teacher are watched more closely. After the warm-up exercise, teachers will introduce the dot plot. Pie graphs, or circle graphs, show percentages or fractions of a whole group. Step 5: If the class is comfortable creating and reading scatterplots, take a few data points from the table and show where they appear on the scatterplot.

Step 9: Distribute the Cultivating Data Worksheets: Scatterplots, Outliers, and Lines of Best Fit printable to students to complete over 1—3 days. Step 6: Ask if the scatterplot shows a relationship between study time and test score and, if so, how. I then go into the three major trends for atomic radius, ionization energy, and electronegativity with students filling out information in a table on their graphic organizer. The water sale averaged 150 L per minute. During these presentations, discuss which equipment might have a one-to-one correspondence for equipment-to-climber, and which equipment might be shared among the team.
The students will also be paired with a higher level student to help guide them through the activities. Step 9: Encourage students to use tables first to represent the problem situation, then move from the tables to graphs, then to equations. An example of a negative correlation might be apparent if we made a scatterplot of hours of television watched versus test scores. The graph below represents the number of dozens of muffins you have y , as a function of the number of hours since the bakery started work that day x. You own a bakery that makes muffins. Test Score: Table and Scatterplot printable and the Cultivating Data Worksheets: Scatterplots, Outliers, and Lines of Best Fit printable. The graphing activity will take 30-40 minutes so the students must remain watchful of the time in order to complete the task before the end of the class period.
As students fill in the rest of the table, ask them how they are determining the cost of the climbing shoes for each row or each number of athletes. The worksheet printable contains three separate worksheets about scatterplots. Have students incorporate this expense in order to form a new table, graph, and equation. Each month she will deposit twice as much as the previous month. How do you measure the center of the data? Sample questions include reading a scenario and determining which graph best represents the situation. The dependent variable the effect — in this case the test score — is on the Y-axis.
Step 2: Ask how one could determine whether or not the relationship exists e. As students become more familiar with the process, encourage them to explore assigning shared equipment to the climbers. Have the group working on the ropes consider this as they represent the problem situation. For the second section of the worksheet students first fill in various elements on a blank periodic table and then compare the various elements to each other using the trends. Ask if there might be a clearer way to show the relationship a scatterplot. In this lesson students learn about the trends of the Periodic Table by doing an inquiry activity, taking notes, watching videos, and doing practice questions. Students will create dot and box plots that represent the data.
The resulting line can be used to make predictions, either by finding a point on the line or by determining the formula of the line and plugging in values. For example for atomic size on slide 11 students will say that size decreases across periods and increases down groups. Determine the rate of change and initial value of the function from a description of a relationship or from two x, y values, including reading these from a table or from a graph. Step 1: Pose the following problem to your class: Do you think there is a relationship between the time studying for a test and the score earned? Step 4: Have students analyze the table after 5 or 6 rows have been filled in. Tony starts an ice cream stand and tracks his net profit over time. Students enjoy the opportunity to independently move around the classroom and visit each station.
Step 6: Ask if the scatterplot shows a relationship between study time and test score and, if so, how. Related Topics: Examples, solutions, videos, and lessons to help Grade 8 students learn how to construct a function to model a linear relationship between two quantities. To begin the lesson I have students begin to figure out the trends for ionization energy, electronegativity, and atomic radius through an inquiry activity. To learn more about this lesson, click on the Lesson Reflection below. By actively engaging in the station rotation strategy, students take ownership in the activity and work in collaborative groups. They will be relating the costs of climbing to the number of athletes involved in the competition.
