RJ instructs your sixth graders in two different methods of determining least common multiples. The first is by listing several multiples of each number, and the second is by drawing factor trees. This is an ideal flipped classroom...

What is the ratio of wins to total games for Mia's soccer team? RJ teaches viewers how to figure it out with a step-by-step procedure. He shows them three different ways to represent ratios: word form, ratio form, and fraction form. 

Here is a fun online activity that learners can use to practice imitating patterns! Along the way, they are exposed to the names of geometric shapes including rhombus, hexagon, octagon, and decagon.

Please excuse my dear Aunt Sally! Sort of like an animated slide show, this lesson walks fifth graders through the order of operations. Also included are a sing-along karaoke video, key vocabulary with definitions, and a seven-question...

Using an amusing amusement park, Sam describes how it is a coordinate plane and how to graph an ordered pair. Perfect for beginners, the animation moves on to point out a tip using the first quadrant of an empty coordinate plane.

To illuminate how afterimage occurs, create a star, square, or other geometric-shaped light for learners to look at for 30 seconds. Then, have them explain what they see as they shift their focus to a blank wall. A full explanation of...

By rolling marbles down a six-foot length of track, physical scientists determine how much energy is lost to heat. It is recommended that you opt for the foam pipe insulation track because more friction slows the marble, allowing...

Here is a fun little exploration of the potential energy potential of falling water. Learners drop water from various heights using a straw, and they analyze the diameter of the splash. Pair this with two more activities of the same...

Help your learners to visualize where historical events have taken place around the globe with a map that details the major regions of the seven continents. 

Explore the world's water without leaving the classroom! In this second of three uncomplicated but wonderful activities, physical science learners feel the pressure of water. They discover that the deeper the water, the stronger the...

Using popsicle sticks and glue, groups must work together to design and build a bridge that can support weight and is aesthetically pleasing. The lesson begins by learners reading about different features of bridge architecture, followed...

Working under specific constraints and with designated criteria, groups work together to create a product using an assembly line process. In addition, they work through the entire engineering design process with an excellent graphic to...

Sure, you may be able to build a better mousetrap, but what about a gum dispenser? In a fun engineering challenge, teams must design and build a working interactive gumball machine with specific constraints and criteria.

In an effort to practice engineering design, STEM classes break out into teams and endeavor to make a working ink pen. To prepare, they read about writing implements through history, patents, and viscosity of liquids. Armed with this...

To prepare for the activity, STEM classes read about nanotechnology and the amazing properties of graphene. They collect a graphene sample from pencils, and then connect them into simple circuits to determine whether it makes a better...

Fascinating reading about nanotechnology, nanoscale properties, and liquid crystals precedes a fun activity for young engineers. They measure their hands in nanometers, research, and then investigate how heat effects a sheet containing...

A comprehensive resource gets fourth grade physical scientists making observations about the period of a pendulum and then applying knowledge to a playground swing. Through seven different stations, they will record observations and...

Sometimes engineering problems that seem easy prove to be more challenging than imagined. Present your class with the challenge to build a functional display tower to support a statue using only the supplies available in class while...

Providing clean water to a town is quite a feat... is your class up for the challenge? After a short reading about water towers, groups work together to design a working water delivery system. The water flow must be adjustable (able to...

A fun and challenging activity for nearly any age group, partners must work together to build the tallest structure possible using paper clips, straws, and pipe cleaners. In addition to being tall, the structure must also be able to...

Check out this amazing, customizable graphic organizer. You can create as many grids as you'd like with two to five columns and three to seven columns. The title is editable as are the labels for the columns and the rows. The process is...

The slope of the land is an important feature when considering the erosion that will occur. In this resource, which is part of a rain garden unit, learners calculate the slope of the proposed garden site. Even if you are not planning a...
