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.

Entropy, it isn't what it used to be. Presentation includes kinetic-molecular theory, heat and internal energy, thermal equilibrium, temperature scales, laws of thermodynamics, entropy, latent heat of fusion, specific heat, calorimetry,...

One of the key questions in statistics is whether the results are good enough. Use an activity to help pupils understand the importance of sample size and the effect it has on variability. Groups collect their own sample data and compare...

The more you text, the less you study. Have classes test this hypothesis or another question related to text messages. Using real data, learners use technology to create a scatter plot and calculate a regression line. They create a dot...

Cut it out! Beginning readers practice sequencing skills at home or at school with a variety of activities that require cutting out multiple sets of picture cards and putting them in the correct order. 

Manufacturers' claims may or may not be accurate, so proceed with caution. Here pupils use statistics to investigate the M&M's company's claim about the percentage of each color of candy in their packaging. Through the activity,...

Intrigue the class by completing a lesson on meiosis, filled with challenging and insightful activities to spark the interest of every person in the room. Each member of the class learns about genetic disorders due to faulty meiosis, and...

How does examining an ice core tell us about weather? Learners set up and explore fake ice cores made of sugar, salt, and ash to represent historical snowfall and volcanic eruptions. From their setups, scholars determine what caused the...

How do you engage pupils in a discussion about osmosis without leaving them overwhelmed? By providing them with the tools to perform an exciting experiment, and they will see osmosis in action! Young chemists and biologists use...

Population density, it is not all that it is plotted to be. Pupils analyze a scatter plot of population versus area for some of the states in the US. The class members respond to eight questions about the graph, specific points and...

Give your young scholars a chance to show what they've learned from the module. The last installment of a 21-part series is an end-of-module assessment task. It covers basic and conditional probabilities, expected value, and...

Determine the number of possible genetic codes. Class members are challenged to determine the number of possibilities of a genetic code that is 20 bases long. They continue to explore the average lengths of broken RNA molecules.

Use expected values to analyze games of chance. The 15th installment of a 21-part module has young mathematicians looking at different games involving tickets and deciding which would be the best to play. They calculate expected payoffs...

Pupils learn everything from how to take scientific measurements, to accuracy/precision, to density and a plethora of topics from a presentation on the metric system.

The density of the huge planet of Saturn is 0.7 g/cm3, which means it could float in water! In the second part of 22, science pupils explore the size and order of the planets. They then calculate weight and/or gravity and density of...

How do robots move? A presentation shows viewers the different types of configurations of that help robots move and lists the advantages and disadvantages of each of the configurations.

The National Women's History Museum provides this interactive resource that permits users to explore women who played key roles during the Progressive Era in the quest for workers' rights, the Settlement House Movement, the Suffrage...

Scholars learn how to make a digital canvas and fill it with artwork by creating a drawing app using the canvas element. The activity requires learners to previous knowledge of arrays and return commands to draw images.

Women were in the workplace long before Rosie the Riveter pushed up her sleeve. Learn about the working options available to women during the Industrial Revolution, the Progressive Era, and the Great Depression with a lesson that...

Be sure to look both ways when making a two-way table. In the lesson, scholars learn to create two-way tables to display bivariate data. They calculate relative frequencies to answer questions of interest in the 14th part of the series.

Spin to win! Individuals calculate the average number of tickets expected based on a probability distribution for the number of tickets per spin. Pupils use that information to determine the average number of tickets that can be won...

Examine the importance of sequence and series through contextual situations. Here, learners partake in a five-day unit that begins with the basics of arithmetic and geometric sequences and series. As it progresses, pupils apply the...

How likely is it to draw a blue marble? Pupils find the likelihood of events and connect that to the probability of the event. They find the probabilities of simple events and show their probabilities on a scale.

Representing data is as easy as pie. Class members construct pie charts given a frequency table. Individuals then determine the size of the angles needed for each sector and interpret the size of sectors within the context of frequency....
