Calculating Measures of Dispersion
Double the fun — calculate two measures of deviation. The lesson plan provides information to lead the class through the process of calculating the mean absolute deviation and the standard deviation of a data set. After learning how to...

Seed Dispersal and Plant Migration
There are five methods of seed dispersal. They include gravity, mechanical, animal, water, and air. Scholars study seed dispersal in lesson five of the series of six. Through discussions, hands-on analysis of different seed types, and...

Measuring Dispersion
Students compute the standard deviation for a given set of data. In this measuring dispersion lesson, students compute the mean, and then the distance from the mean for each data point. They find the standard deviation of the data.

Goal Setting
Students understand how they can incorporate dietary guidelines in their daily life. For this investigative lesson students set dietary goals and incorporate an activity to learn how to create a new seed variety while studying...

Wind Power
Many have played with seed helicopters at one time or another. Learners use paper to create their own helicopters to model the Linden seed. After a discussion of seed dispersal, they take their models outside, let them go, and make...

Starting With Stats
Statisticians analyze a data set of student IQs by finding measures of central tendency and dispersion such as mean, median, mode, and quartiles. They practice using a graphing calculator to find the values and analyze box plots and...

Measures of Central Tendency: Range
In this measures of central tendency worksheet, students complete 40 problems in which a set of data is analyzed and the range is calculated. This page is intended as an online activity, but may be completed on paper.

Build a Weather Vane
Students construct a weather vane using their knowledge of some geometric shapes. In this weather lesson, students work in pairs to create a weather vane in order to measure wind direction. Students follow precise...

Connecting Measurement
Students participate in activities the connect measurement to geometry, statistics, estimation, and the real world. They collect measurements from their elbow to the tip of their middle finger and make a box plot of the data as well as...

Analyzing and Interpreting Statistics
Use measures of variance to compare and analyze data sets. Pupils match histograms of data sets to their respective statistical measures. They then use calculated statistics to further analyze groups of data and use the results to make...

#24 How Much Air Is In Foamed Polystyrene Products?
Students are challenged to come up with a good estimate of the amount of air in foamed polystyrene products. They use this gas evolution experiment and as such have students measure the gas generated when foamed polystyrene is degassed...
Curated OER
Let's Get Carried Away
Students discover how seeds travel from their parent plants in search of water, sunlight, and nutrients, and conduct experiments in which they note characteristics that encourage seed dispersal by means of wind, water, animal carriers,...

Through Thick or Thin!!!
Students differentiate between high and low viscosity. Students collect, graph, and interpret data, then quantitatively measure polymer solids. Students experiment with a household example of an emulsion polymer.

Global Change: Where Land, Air and Water Meet
Students discuss the atmosphere as a mixture of gases. In this science instructional activity, students explore the world's oceans and fresh waters understanding that there are dissolved chemicals. Students realize that many substances...

Exercise Those Statistics!
Young scholars participate in various activities, measuring their pulse rates and recording the data. They analyze the statistical concepts of mean, median, mode, and histograms using the data from the cardiovascular activities.
Curated OER
Do Objects Vary Very Much?
Students examine the concept of standard deviation, calculating mean, and collecting data. They measure the standard deviation in a bag of M&M candy, record the data, and calculate the mean.
Curated OER
Stemmin'-n-Leafin'
Students make stem and leaf charts to determine the measures of central tendency using test score data. They analyze the data to draw inferences which they share with the class. They complete the associated worksheets.

Alien Invasion
Students research how alien species can change an ecosystem. In this coral reef lesson, students describe invasive species and site evidence how these species came to be invasive and what control measures are possible.

Chernobyl 2 - Air Currents
Learners create a scale model of the affected area of the Chernobyl disaster. Using this scale model, they simulate the explosion and the resulting uneven dispersal of fallout due particularly to wind direction and weather conditions.

Welcome to Populations!
Students define what population is in their own words. In this biology instructional activity, students explain different ways to measure population density. They interpret population graphs.
