Mathematics - 4th Grade

• Dino Drool
  In this activity students build a water cycle model and monitor it for a 2-week period helping them to understand that water changes state as it moves through the cycle.
• Food Intake and Physical Activity
  Students graph their estimations of caloric intake and caloric expenditures
• Getting A Grip On Graphs
  Students will gather a variety of data and create a graphs to display the data.
• Graphin' and Glyphin' Utah Weather
  Students will use glyphs as a way to visually represent information about Utah weather.
• Graphing the Weather
  Students take weather readings using simple weather instruments and predict the weather in this lesson. They take readings for a month during a season and chart it. With the information, they can graph what is happening with each instrument each day and use the data to show patterns the storms follow for that particular season.
• Picnic Possibilities
  Students will learn to use weather data to plan outdoor activities.
• Weather Instruments
  Students will learn about air pressure and how it is measured. Students will also learn how density is measured. Students will then create two or three weather instruments to measure these parameters and will create graphs of their data.
• Winter and Summer Storms Scenarios
  In this lesson students will understand that there are reasons that summer and winter storms are different, and will discover the patterns for each.

• Categorical and Numerical Data
  Students will compare representations for categorical and numerical data.
• Collecting, Representing, and Interpreting Data Using Spreadsheets and Graphing Software
  Spreadsheets and graphing software are tools for organizing, representing, and comparing data. This activity illustrates how weather data can be collected and examined using these tools.
• National Population Projections
  Students will examine the United States Census Bureau website to investigate population projections from 1990-2100. Using the five provided pyramids, students will analyze the data to determine how the population is distributed over time, and explain what factors might contribute to these trends.
• State Population Projections
  Students will examine the United States Census Bureau website to investigate projections of the total population of states from 1995-2025. Using the provided data, students will analyze statistics from five states of their choice, develop specific research questions using the data, and create three graphs to compare and contrast the information.
• Uncertainty
  Students will analyze collections of both their own data and others. Students will create data distributions in order to determine the highest, lowest, and middle values, as well as pile ups and gaps, for a particular set of data. Students will also be introduced to the notion of sample size and how it can affect results. Finally, students will begin to explore the questions that can be answered based on a set of data, and the additional questions it might prompt one to ask.
• Working With Categorical Data
  Students will formulate and refine questions which can be addressed with categorical data. They will consider aspects of data collection such as how to word questions and how to record the data they collect. Finally they will represent and analyze the data in order to answer the question posed.
