Use the power of mathematics to find the number of red chips in a bag — it's a little like magic! The activity asks learners to collect data to determine the percentage of red chips in a bag. They calculate the margin of error and...

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.

Don't leave your classes vulnerable in their calculations! Help them understand the importance of calculating a margin of error to represent the variability in their sample mean. 

Error does not mean something went wrong! Learners complete a problem from beginning to end using concepts developed throughout the last five lessons. They begin with a set of data, determine a population proportion, analyze their result...

Take a good look at tree leaves and notice the adaptations for collecting solar energy. Pupils trace the margins of five different leaves onto graph paper and count the number of squares covered. They then relate this infomation to the...

Students review concepts related to market structures and competition. Using supply and demand, they identify what factors cause them to shift and analyze business downward facing demand curves. They compare and contrast the abilities of...

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...

Here is a fantastic World War I research project that includes clear guidelines for topic choice, guiding questions, and suggested presentation products. Research subjects range from battles of the war, trench warfare, and weaponry, to...

Ninth graders gather samples of different tree leaves in their neighborhoods, and on school grounds, and identify several species of common South Carolina trees using leaf and growth characteristics with aid of dichotomous key.

High school economists learn about the stock market in a project where they "buy" and track stocks. The author of this resource reports it is the high point of her 12th grade economics course, but no resources are attached. After viewing...

High schoolers study photosynthesis and chemosynthesis.  In this chemosynthetic lesson students explain the processes of these and define terms. 

Students examine how oceanographers use chemical and physical parameters of seawater to locate hydrothermal vents.  In this ocean lesson students complete an activity and worksheets.
