Students examine fossil fuels, nuclear and renewable fuels. They study investigate types of heat transfer such as convection, conduction, and radiation. They complete crossword puzzles based on the vocabulary. They design, construct and...

Students study the causes of different types and speeds of landslides. They determine that landslides are the result of gravity, friction, and the materials involved. They examine the step engineers are taking to prevent and avoid...

Students research tornadoes. For this weather lesson, students construct a KWL chart on tornadoes and view the video National Geographic-Tornadoes. Students discuss the facts they learned from the film and complete the KWL chart.

High schoolers examine the definitions of biomas gasification and generate their own biomass gas.  In this renewable energy lesson students collect gases and roast a marshmallow. 

Students evaluate pH levels through a solubility experiment. In this pH levels lesson, students list characteristics of acids and bases. Students complete their own pH level experiment. Students go to the GEMS Alien Juice Bar website to...

Students research volcanoes. In this volcanoes instructional activity, students visit websites with worksheets about the terms for volcanoes and volcanic eruptions in the world. Students complete the work online and play a game for...

Students investigate the force of compression and how it acts on structural components through a hands-on group project. They use everyday products such as paper, toothpicks, and tape to construct a structure that will support the...

Students explore the solar system. In this solar system lesson, students use Internet and print resources to research a component of the solar system. Students create travel brochures based on their research findings.

Learners explore the solar system. In this space science lesson, students take notes on the solar system provided by their instructors. Learners then collaborate to design a computer-generated drawing of the solar system.

Students research how roller coasters work. In this physics lesson plan, learners research the history of roller coasters and the safety factors in the design of a roller coaster on the website www.learner.org/exhibits/parkphysics. They...

Students explore the water cycle. In this earth science lesson plan, they read the book Water Dance by Thomas Locker and use an interactive whiteboard to review the water cycle with an interactive website.

Young scholars explore the concept of patterning using musical instruments. In this music lesson plan, students identify several instruments and practice playing patterns with them. Young scholars identify the patterning in a musical piece.

Students study the concept of bird migration. In this bird lesson, students read Make Way for Ducklings, discuss the concept of community, and write reflections.

Students explore the concept of chemical formulas.  In this chemical formula lesson, students watch a video about balancing chemical equations.  Students conduct an experiment using silver nitrate and sodium phosphate. ...

Students investigate how rocket thrust is generated with propellant. They listen to a teacher-led lecture, discuss Newton's third law of motion, answer discussion questions, and view photos of rockets and rocket designs.

Young scholars work together to review what they know about damage during tornadoes. They design a structure that they hope protects people against tornadoes. They share their structure with the class.

This resource provides information about commutative and associative properties of addition.

Children need to understand why the mathematical properties work and how they are applied. In this activity, we explore modeling and "proving" the associative property.

[Free Registration/Login may be required to access all resource tools.] Students practice applying the associative property to multiplication problems.

Brush up on your math skills relating to the associative property then try some practice problems to test your understanding.

In this lesson on the associative property of multiplication, students explore grouping factors, learn key vocabulary, and apply their learning to a real-life scenario.

An introduction to the associative property of multiplication. Includes examples and practice problems throughout, along with explanations of solutions.
