In this trees lesson, 4th graders read the book, A Tree is Growing and complete a KWL chart on how trees grow and how they are used. Students research the symbiotic relationship of humans and trees, create tree collages, plant a...

Many organizations put on barbecues in order to make money. In a real-world math problem, the money allotted to purchase steak and chicken at this barbecue is only one hundred dollars. It is up to your potential chefs to figure out how...

Fifth graders explore the relationship between potential energy and kinetic energy.  In this energy lesson, 5th graders examine objects and describe  potential and kinetic energy of the objects. Students complete two worksheets.

Students investigate density and its relationship to air and gas. Students perform experiments to determine if gases have mass. They explore possible ways to figure out the density of gases.

Aspiring astronomers study stars. They compare stars and explain the relationship between radius, mass, and diameter. By creating a star simulation, they discover how a binary star system's orbit can cause changes in the observed...

Your older elementary students investigate electromagnetic energy and the electromagnetic spectrum. They will observe 7 items represented in the electromagnetic spectrum and make a poster of all the things the items have in common. After...

An interesting instructional activity on hypothesizing about the diameter of a drop of blood that is splattered. To test their theories, learners work in groups to make blood droplets splatter from different heights. They use graphed...

Does carbon dioxide really affect temperatures across the world? This fifth installment in a six-part series investigates the relationship between carbon dioxide and global temperatures. Graphs created from genuine data help...

Students determine that the relative concentration of copper ions in water can be determined by a color comparison. They make a copper (II) sulfate solution of a given concentration. Students dilute their initial solutions until their...

Scholars learn to create scatter plots and investigate any relationships that exists between the variables with a lesson that also show them that statistical relationships do not necessarily indicate a cause-and-effect...

High schoolers find the relationship between the variables based on experimental data. They determine mathematical relationship between pH and the amount of hydrogen Ions in solution.

Eighth graders examine the relationship between race and employment in the tobacco industry. Using the text, they evaluate the impact of polical and economic changes on life in North Carolina. In groups, they research different...

Mathematics can model just about anything—so why not simulate the height of water in a toilet bowl? The lesson asks pupils to create a graphical model to describe the relationship of the height of the water as it empties and fills again....

Young scholars investigate the relationship of the steps in the water cycle, and create a simulation of the water cycle in a jar.

Through the examination of the relationship between the lengths of the sides of a triangles learners will learn the classification of triangles (acute, right, or obtuse).

Learners discuss the relationship between and the equivalent forms of rational numbers. They will convert numbers from decimals to fractions, understanding they are equivalent, but just different forms.

Your advanced physics class will appreciate this lesson in which they use magnetic field sensors to determine the relationship between the number of turns per meter of a solenoid and the magnetic field produced. The materials for this...

Discover how trend lines can be useful in understanding relationships between variables with a lesson that covers how to informally fit a trend line to model a relationship given in a scatter plot. Scholars use the trend line to make...

How can an object as heavy as an airplane fly? Turns out the answer is quadratic! Your classes explore the Bernoulli Effect through an interactive graph representation. As a plane increases in speed, the lift force also increases. Young...

Study logarithmic properties using a triangle. A clever manipulative shows how a triangle can represent the three parts of a logarithmic or exponential equation. Pupils review the concept and then answer guiding questions to further...

Explore a geometric sequence model through a simulation. Learners change the starting drop height of a ball and watch how the heights of following bounces change. They consider the ratio of the consecutive bounces as they analyze...

Who wouldn't want to wear four pairs of sunglasses? Each pair of sunglasses reduces the percent of incoming light by one-half. An interactive tutorial helps young mathematicians build a graph that models this scenario. They...

Second graders use an online database to research information about bird's beaks and feet. Using that information, they discover what foods they eat and where they live. In groups, they cluster the food/habitat and beak/feet data to make...

Students explore the states of matter. They discuss the different phrases of matter and categorize everyday substances as solids, liquids, or gases. Students explore the relationship between the phases on an atomic level and the role of...
