Students examine the U.S./Canadian trade relationship. In this economics lesson, students participate in a simulation that requires them to use economies of scale to trade laterally.

Young scholars understand the meaning of scale and calculate various problems related to Cyberchase videos. In this scaling lesson, students measure a Proporciona boat using blades of grass. Young scholars calculate dimensions based on a...

Launch your class on an exploration of the solar system. Learners construct solar system models to scale and get a better understanding of our place in the vast void of space. This is a great way for them to cement their understanding of...

Pupils determine scale factors from one figure to another and the scale factor in the reverse direction. Scholars compute the percent changes between three figures. 

The 12th lesson in a series of 20 opens with a demonstration of exponential functions using pasta. This concept is connected to the Richter Scale, which is also an exponential function. Scholars compare the exponential scale that...

Students gain an understanding of how the powers of 10 and scientific notation can be used to represent the scale of things in the universe. They relate the number of stars in the universe to the number of grains of sand on Earth's beaches.

Help your class understand the magnitude of the distance between Earth and Mars with an activity that asks small groups to use balloons to create scale models of the Earth, Moon, and Mars. Class members figure out the distances...

Chris Van Allsburg's Two Bad Ants provides third graders with an opportunity to examine point of view and how the point of view of others may differ from their own.

Understanding how functions transform is a key concept in mathematics. This introductory lesson makes a strong connection between the function, table, and graph when exploring transformations. While the resource uses absolute value...

The density of the huge planet of Saturn is 0.7 g/cm3, which means it could float in water! In the second part of 22, science pupils explore the size and order of the planets. They then calculate weight and/or gravity and density of...

A PowerPoint presents features of polymers and two of its categories (thermoplastics and thermosets). Instructors conduct demonstrations to illustrate the Weissenberg Effect and the Barus & Kaye Effects of polymers in the first...

What's missing from most studies of the American Revolutionary War is information about the role African Americans played in the conflict. To correct this oversight, middle schoolers research groups like the Black Loyalists and ...

Every living creature can leave a fossil record, yet most fossils belong to extinct organisms rather than ones currently living. Scholars learn about dating rock layers, fossils, and the environment of the past. Pupils understand that...

Lead your class through the procedure to create a scale model of the solar system. This resource reinforces concepts of scale and the mathematics involved, as well as the planets. Attach paperclips and staples to index cards to show the...

Proportions are ratios found using multiplication or division. Middle schoolers solve measurement problems, find a figure's missing dimension, and find the distance between two points. Resource features four lesson plans with detailed...

Students compare bacteria and viruses and their roles in biotechnology and bioterrorism. They outline fundamental steps of bacterial transformation and the possible selection processes to identify transformants. They discuss...

If Earth is modeled by a grapefruit, what planet could be represented by a golf ball? This activity uses everyday and not-so-everyday objects to create a model of the Solar System.

How did our universe really begin? Explore the Science Big Bang Theory and Cosmic Microwave Background (CMB) with this multiple activity-based instructional activity that demonstrates that the increase of density due to the decrease of...

The Hopewell people of the central Ohio Valley used right triangles in the construction of earthworks. Pupils use the Pythagorean Theorem to determine missing dimensions of right triangles used by the Hopewell people. The assessment task...

Teach the basics of measurement and conversion with a five-lesson resource that builds an understanding of proportion and measurement conversion from elementary through high school. Initially, young scholars use ratios to determine soup...

Investigate the procedure for developing computer chips! Learners use solar print paper to create both positive and negative images. They observe the effects of single and multiple exposures and compare results.

How do you teach a student with visual impairments about the conservation of mass? You use tactile models that represent the theoretical concept. Baking soda and vinegar are used to add gas to a deflated balloon. Learners will feel the...

Bringing together the young artists and the young organizers in your class, this lesson takes that popular topic of tessellations and gives it algebraic roots. After covering a few basic properties and definitions, learners attack the...

What's the term for clouds that look like fluffy cotton balls? What about thick, gray clouds? Learn the names and descriptions for each type of cloud with a activity and activity. Learners read four columns of high-level, mid-level,...
