At the top of the page are a reading passage and colorful diagram that depicts the tug-of-war that occurs between bonding molecules due to electronegativity. High school chemists fill in a chart with electronegativity values, the...

How important is momentum? Pupils investigate and apply the definition of momentum as they conduct analyses during a series of one-dimensional collisions. They infer the relative masses of two objects by carefully staging and predicting...

What must a sentence contain in order to be complete? What different types of sentences exist? Look at declarative, interrogative, and exclamatory sentences with this 17-slide presentation. Several example sentences are shown, and the...

What happened to the plant in math class? It grew square roots. Here, a set of 11 worksheets provide a review of plant reproduction. It includes the structure of a flower and each part's function, pollination, fertilization, seed...

Students determine how force on an object affects its movement. In this force and motion lesson, students take digital pictures of objects in the school setting that are pushed and pulled. They develop a presentation using the digital...

Middle schoolers build models of types of levers. In this simple machines lesson, students use dowels and modified wooden rulers to build different types of levers. They compete to create the most efficient lever in the class.

In this rocks worksheet, students compare and contrast the 3 types of rocks: sedimentary, igneous, and metamorphic. Students complete 1 graphic organizer.

In this circuits an Ohm's Law instructional activity, students read about the differences between series and parallel circuits. They are given Ohm's Law and the definitions of current, voltage and resistance. Students match variables...

Third graders study and define force. They determine that the cause of movement is pushing or pulling which are the types of force used when operating simple machines. They experiment to determine which object requires the most amount of...

Host a design challenge of Olympic proportion! Junior engineers build their own bobsleds using simple materials. The activity focuses on kinetic and potential energy and how the center of mass affects motion on a downhill track....

Friction and gravity are always at odds! Learners complete a set of activities to explore the relationship between friction and gravity. Groups make conclusions about the factors that affect the amount and type of friction between surfaces.

Ride the wave to an understanding of refraction! The first in a series of two inquiry-based lessons challenges learners to create transverse waves with two different types of springs. As their wave hits an object, they observe the change...

Introduces your class to the types of loads experienced by a bridge. Groups calculate the ultimate load combinations to determine the maximum load requirement. Using this information, builders then determine the amount of material...

Make Newton proud. Scholars apply their understanding of forces and energy to an engineering design challenge. They learn about simple machines, create a presentation on Newton's laws, and develop a balloon-powered car.

Even light cannot leave the force of a black hole! Learners use a model to explore the gravitational force of a black hole. An elastic bandage and heavy ball serve to create the hole, while marbles become the victims of its strong force.

Wow! Colorful and simple, these 160 slides introduce the various forms of energy, along with a relevant image. Some of the images are animations, which help beginning physical scientists to visualize the flow of electrons or energy! This...

Students identify and classify the powers and responsibilities of all three levels of executive government in Australia. In this executive government lesson, students discuss the various services that the government in...

What are packaged food products really made of? This lesson will prompt your learners to consider and investigate the source of ingredients in their food. They begin by breaking into groups and analyzing food labels by identifying...

Make your work as a teacher a little easier with a physical science project on simple machines. After introducing young scientists to these devices and identifying their different uses around the school, this project engages...

Pupils study scientific names and descriptions of forces.  In this motion activity students organize information into a graphic organizer then teach it to other pupils. 

Let the resource stretch the minds of your young scientists with a lesson about tensile strength and stiffness of materials. Groups consider how easily materials stretch and relate this property to engineering design.

Students examine types of forces and movements. They identify different causes that can affect movement and speed. They create their own predictions about they believe to be the outcome of an experiment.

How have the women's share of the labor force and chosen occupations evolved in the United States over the last century? Using census reports, graphs detailing the gender makeup of the labor force, and analysis of the careers of...

In this forces in action worksheet, students identify types of forces, label forces of action, and draw forces of action as they respond to 6 short answer questions.
