What are the issues surrounding water quality? Viewers of this short presentation gain information about the importance of clean water, the lack of fresh water, water contamination, and ways that engineers treat water. 

Eighth graders explore mathematics by conducting a series of investigations using a colorimeter. In this math lesson, 8th graders explain the purpose of food irradiation. They collect data and graph them.

Middle schoolers investigate the use of math in everyday life. They investigate several occupations and pay scales. They complete spreadsheets that show how monthly bills can be organized using technology. They use word processing...

Pairs work together to determine whether unknown solutions are either acids or bases by using a red cabbage indicator solution. After determining the general pH of the unknown solution, classmates blow into the same indicator after...

Elementary schoolers examine the uses of rulers, scales, and measuring cups. They determine the criteria for the use of each tool and visit different areas of school to find items that can be measured with these tools. Everyone takes...

The first activity in this resource has learners computing the mean and standard deviation of two different data sets and drawing conclusions based on their results. The second activity has them using a dice-rolling simulation to...

What linear equation will fit this data, and how close is it? Through discussion and partner work, young mathematicians learn the procedure to determine a regression line in order to make predictions from the data. 

Students explore inequalities to determine the optimal solution to maximize a profit for a company. In this linear programming lesson, students discover how to graph inequalities and how to determine the algebraic representation of a...

Systems of parallel lines have no solution. Pupils work examples to discover that lines with the same slope and different y-intercepts are parallel. The 27th segment of 33 uses this discovery to develop a proof, and the class determines...

Reduce variability for more accurate statistics. Through simulation, learners examine sample data and calculate a sample mean. They understand that increasing the number of samples creates results that are more representative of the...

Investigate what is pushing on us. An intriguing lesson has pupils calculate the amount of force on various squares due to air pressure. Using the data, individuals create a graph in the third lesson of the Up, Up and Away unit...

Increase your sample and increase your accuracy! Scholars complete an activity that compares sample size to variability in results. Learners realize that the greater the sample size, the smaller the range in the distribution of sample...

They say you can interpret statistics to say what you want them to. Teach your classes to recognize valid experimental results! Pupils analyze experiments and identify flaws in design or statistics. 

Efficiently graph a quadratic function using transformations! Pupils graph quadratic equations by completing the square to determine the transformations. They locate the vertex and determine more points from a stretch or shrink and...

It is a-maze-ing how lost one can get. Teams reconstruct a simple maze and solve it. Participants create an algorithm that a robot would follow in order to solve the maze as well. The activity includes an extension directing pupils to...

Looking for an excellent lesson that incorporates math, science, and technology? Groups of three learners use a viewing tube to perform an experiment, and discover how to organize their data into an Excel spreadsheet.  This is a...

Relax ... now visualize the data. Introduce pupils to creating charts from a single data set. Using chart tools included in spreadsheet programs class members create data visualizations that display data. The...

Wrap up an engineering lesson plan with a worthwhile project. An engineering design task challenges groups to develop a package for a pharmaceutical company given constraints on the volume. Learners then create a presentation to...

Students make an eco-friendly vehicle to help make transportation better for the environment. In this transportation lesson plan, students learn how transportation inventions are bad for the environment. They then see how engineers have...

Investigate how public key cryptography works. Scholars continue their study of one-way functions and asymmetric keys and apply this information to public key cryptography. They use an app to explore public key cryptography and its...

Make Newton proud. Scholars apply their understanding of forces and energy to an engineering design challenge. They learn about simple machines, create a presentation on Newton's laws, and develop a balloon-powered car.

Seventh graders use the Internet to research the holiday of Kwanzaa. Using the information, they create a brochure to promote the holiday to others. They email the information to a friend to end the lesson.

High schoolers examine the guidelines the United States Department of Agriculture places on food. In groups, they create a list of the foods they consume and discuss the political and environmental implications of purchasing the food. ...

Students investigate apples. In this reading comprehension lesson, students read a book about apples then compare and contrast, make graphs, distinguish between fact and fiction and work in groups. Students work in groups...
