Think critically — and linearly by applying linear equations to solve real-world problems. Young mathematicians write equations to model the profit on popcorn and cotton candy at a carnival and solve problems using these equations.

Investigate field properties of real numbers. Scholars use a table for a given operation to determine the identity element. They use the same table to find a missing value in an equation.

Horses need exercise, too. Scholars create linear equations to model the perimeter of exercise fields for horses. They finish by solving their equations for the length and width of the fields.

Rotate this resource into your lesson plans. Scholars rotate polygons in the coordinate plane by multiples of 90 degrees. They then compare the original and new figures to develop conjectures about coordinate points after rotations.

Improve your fifth graders' persuasive writing skills in four weeks. Working independently, in peer editing groups, and with instruction, writers work over the 17 sessions to craft an argumentative essay. They craft a...

"Statistics are no substitute for judgment" - Henry Clay. Young mathematicians use provided statistics from a soda taste test to explain why conclusions are faulty. They devise a new test that would be more appropriate than the one given.

Students demonstrate the genetic principles of Heredity. They discover that each species has a unique Genetic fingerprint and that people can use "Genetic fingerprints" to solve a number of problems. They discuss examples of uses of DNA...

Tiny particles can provide big learning opportunities! Middle school scientists explore the world of nanoparticles through reading, discussion, and experiment. Collaborative groups first apply nanotechnology to determine water...

Show us your moves. Using sensor equipment, scholars track the motion of different movements, such as jogging, skipping, or jump roping. They analyze velocity and acceleration and create graphs representing each movement.

Don't be shocked when your class has a blast making their own batteries! Science scholars examine a dry cell battery, then design and construct a wet cell battery. The activity guides them through the parts of a battery, the variables...

Your mission, if you decide to accept it, is math skills practice. In this app, Mission Impossible meets basic number operation skills, and your students are the secret agents. 

Ready to roll up those sleeves and get your hands dirty? Dirty with soil science content, that is! Overcome those "But it's just dirt" objections with a trip outside to collect soil samples for some in-class analysis. Use the...

It's a race to the finish! Which ice cube will melt the fastest? Scholars discover the effect thermal energy has on melting ice. They experiment with melting ice cubes on different materials and learn that even at a consistent...

Explore the function of enzymes through a series of lab investigations. Learners use household enzymes such as hydrogen peroxide to model the role of enzymes. The enzymes break down proteins with and without a catalyst.

How do the laws of motion work in space? Learners explore Newton's laws of motion in different experiments as part of the Christa's Lost Lessons series. They rotate around the room in three stations to experience each law in action using...

Many problems in life have more than one possible solution, and the same is true for advanced mathematics. Scholars solve seven problems that all have at least two solutions. Then three higher-level thinking questions challenge them to...

Have your young scientists questioned why plants grow a particular way? Through this learning opportunity, scientists gain firsthand knowledge about how plants develop and various factors that affect rates of growth as they bring plants...

Binary graphing ... bit by bit. Pairs work together to develop a protocol in order to send the points of a graph. One partner sends the points and the other receives them and tries to recreate the graph. The pupils use the rubric to...

Polygons — it's all about the angles. Groups work with dynamic geometry software to find the sum of the measures of the angles of various polygons. After finding the information for several polygons, the groups generate a formula that...

The biopoem is a great way for instructors to get to know class members, classmates to get to know each other, and readers to flesh out their understanding of a character. Why not create a biopoem for a character from Oedipus the...

What's the difference between a rock and a mineral? And what properties are used to identify minerals? The first installment of a five-part series on earth materials and processes prompts young scientists to identify a set of...

Provide guidance and practice of the useful skill: solving rational equations using both an algebraic and graphical approach. Pupils solve increasingly more difficult rational equations using algebraic methods. After, they...

Pupils work to find probabilities by using areas under the normal curve. Groups work to calculate z-scores and solve real-world problems using the empirical rule or tables.

Using the 5E method for teaching about kinetic energy, potential energy, and conservation of energy, this two-week unit with many videos and possible extensions is sure to keep pupils engaged as they are learning.
