"Clean the data!" "I did not know it was dirty." Introduce your class to the process of cleaning data so that it can analyze it. Groups work through a guide that demonstrates the common ways to filter and sort data. Pairs then...

Statistics can be manipulated to say what you want them to say. Teach your classes to be wise consumers and sort through the bias in those reports. Young statisticians study different statistical reports and analyze them for...

How accurate is data collected from a sample? Learners answer this question using a simulation to model data collected from a sample population. They analyze the data to understand the variability in the results.

We know that sample data varies — it's time to quantify that variability! After calculating a sample mean, pupils calculate the margin of error. They repeat the process with a greater number of sample means and compare the results.

Here's the perfect lesson plan for those who think the world needs faster pumps. Building on the previous activity, scholars work to make the pumps function faster in transferring water between containers. They try adding an additional...

How many practice lay-ups do you think Michael Jordan has done in his lifetime? Too many to count, but he had to start somewhere! Practice is the key to getting better in any activity. Look through this basketball instructional activity...

Scholars apply the concepts of box plots and dot plots to summarize and describe data distributions. They use the data displays to compare sets of data and determine numerical summaries. 

Pupils work several real-world problems that use percents in the 11th portion of a 20-part series. The problems contain percents involved with taxes, commissions, discounts, tips, fees, and interest. Scholars use the equations formed for...

As an introduction to Sharon Creexh's Walk Two Moons, a volunteer dons a pair of boots and walks about the classroom.Observers then ponder the axiom, Don't judge a man until you've walked two moons in his...

Students explore the concept of mathematical models. In this mathematical model lesson, students create a mathematical model from data from 4 cities over 15 months. Students are told they are working for a weather station. Students...

Continuing from the previous lesson in the series, scholars learn to use positive and negative integers to describe real-world situations. In groups, they come up with their own situations for given positive and negative integers. 

The difference between accuracy and precision is fundamental for high school science learners. Using test kits for nitrate concentration in water, they compare readings with each other. They consider the accuracy, precision, and bias of...

Students make a prediction. In this applied science lesson plan, students guess the number of items in a jar. Students create a bar graph to show the predictions and the actual amounts.

Sometimes the best view is from the farthest distance. Satellite imaging makes it possible to create altitude maps from far above the earth. A three-part activity has your young scientists play the role of the satellite and then use...

Students research various events during the War of 1812 and then create magazine articles with supporting illustrations, students are in control of their learning.

What was Bryce's mistake? Through analysis of a student work example, learners develop their own ability to compare the fractions one fourth and one half. Central to this activity is the concept that, when comparing fractions, the whole...

Students construct bar graphs using the results from various experiments. In this graphing lesson, students review data from a previous experiment and demonstrate how to construct a bar graph. Students use a checklist to ensure...

Students explore ways to assess the accuracy and reliability of data reported by Journey North observers.

Students discuss parachutes and write a procedure to determine the effect of different size parachutes and different masses on the time it takes the masses to fall. They record all their data from their experiment then write three...

What is autumn like in Shanghai? How much rain falls during September in Sydney? Is Moscow cold in October? Take a virtual trip around the world with a research assignment on autumn in different countries. After learners answer questions...

Get to know more about the characters of the novel The Lion, the Witch and the Wardrobe by C.S. Lewis by comparing and contrasting their character traits using a Venn diagram.

Looking for an estimation activity a bit more involved than the typical "guess the number of jellybeans in the jar" game? Here, learners use a picture to estimate the number of people at a large event, look for potential problems with...

Students experiment with primary colored water to mix new colors. They record new colors on a simple data sheet and share opinions on their work.

The use of box scores from baseball games is the foundation of this math lesson. Organize your class into groups of four, and give identical box scores from a baseball game that was just played. Have them create word problems from the...
