Investigate the relationship between independent and dependent variables. Individuals begin by identifying independent and dependent variables from different problem situations. Then, using specific guidelines, they create posters...

Milk does a body good ... unless, of course, someone is lactose intolerant. Pupils play the role of pharmaceutical scientists in a guided inquiry lab about lactase. Lab groups collaborate to learn more about lactose intolerance, how...

Mrs. Moore's class is trying to earn money for a trip to the science museum, but how much more do they need? Solve this problem with your own class as they develop their ability to model real-life situations algebraically. As an added...

What does viscosity have to do with splatter? An activity shows that the viscosity of a substance is inversely proportional to the distance of its splatter. Learners conduct the experiment by collecting data, graphing, and analyzing...

It seems the post office has run out of stamps! Learners build all the values of postage available if the post office only sells five- and seven-cent stamps. The task provides an opportunity to create an expression in two variables and...

Time to come clean! Scholars continue preparing the shampoo they created in the previous two lessons. The purpose of this stage is to calculate the perfect amount of additive to make the shampoo lather. 

Have you ever wanted to build a conductor? Here is a activity that takes pupils through building a conductor based on Drude's model in order to better understand electricity.

Babies grow at an incredible rate! Demonstrate how to model growth using a linear function. Learners build the function from two data points, and then use the function to make predictions.

Obesity is a worldwide concern. Using survey results, learners compare local BMI statistics to celebrity BMI statistics. Scholars create box plots of the data, make observations about the shape and spread of the data, and examine the...

True or false — Double Stuf Oreos always contain twice as much cream as regular Oreos. Scholars first measure the masses of the filling in regular Oreos and Double Stuf Oreos to generate a class set of data. They use hypothesis testing...

Keep your pets slim, trim, and healthy using mathematics! Pupils use a linear programming model to optimize the amount and type of food to provide to a pet rabbit. They model constraints by graphing inequalities and use them to analyze a...

Agriculture is truly a math-based profession! Help the dairy farmer determine the supplies needed to complete his barn. Using given dimensions, learners build equations and use units to determine the correct amount of materials.
