A short PowerPoint to help increase pupils' understanding of pressure. A number of pictures show different types of shoes and open a discussion of how force from a body is applied over different areas, (which translates into different...

What does stretching a balloon have to do with equilibrium? Groups explore preconditioning by stretching a balloon to a point of equilibrium. They then measure the amount of force required to stretch the balloon to the same point several...

Need some activities to go along with your unit? A collection of hands-on activities from PBS offers opportunities to add to your electricity, sound, and force units. The electricity activities revolve around building a...

Force the plane through the air. The lesson introduces the force on an airplane that makes it go forward. Pupils learn how Newton's laws of motion apply to flight in the eighth segment of a 22-part unit on flight.

The laws of momentum can lead to fun! Learners with visual impairments use bowling pins and a bowling ball to model the law of conservation of momentum. They take turns bowling with differing degrees of force to explore how energy is...

Learners won't have to squirm when asked the facts after completing an intriguing lab investigation! Hook young scholars on science by challenging them to verify Hooke's Law using a gummy worm. Measuring the length of the worm as they...

Do charged and neutral particles behave differently as they undergo phase changes? Science sleuths examine two types of attractive forces using an informative interactive. Pupils can vary the amount of Van der Waals attraction present...

A succinct set of slides covers the main points for your weather unit. From the factors that contribute to conditions, to fronts and extreme occurrences, to the different types of clouds, numerous facts are listed in bullets. The only...

There's quite a bit in this physical science packet. First, how is heat transferred? Learners read a brief explanation of conduction, convection, and radiation before identifying common occurrences (with pictures) as one of the three....

How much can opinion influence a news story? A standalone resource discusses the importance of John Brown's Raid through the lens of journalism. Learners analyze two different texts, one from the perspective of the North and the other of...

Students explore constructive and destructive forces. For this constructive and destructive forces lesson, students complete a WebQuest. Students explore the different types of forces and their effect on the surrounding geography. When...

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...

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.

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...

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...

Can you catch the same cold twice? Elementary and middle schoolers learn about what happens when a virus attacks their bodies, and how the immune system never forgets a virus, with an entertaining comic book. The packet includes...

Obviously, a sturdy bridge is the desired outcome. Pupils select from one of four different types of truss bridges, then construct a model of the bridge from craft sticks and glue, making sure that it satisfies certain constraints. They...

Get your class to take a closer look at DNA. Pupils conduct research to determine the methods used by scientists to analyze the molecular structure of DNA. The class members investigate different types of molecular imaging along with gel...

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...

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 view examples of different types of erosion. In this erosion activity, students discuss the different types of erosion and how erosion changes Earth. Students explore erosion and the effect it has on engineering.

Introduce your class to to the remaining three simple machines-- the lever, pulley, and the wheel-and-axle with a plan that includes the three different types of levers in the discussion of levers. The lesson continues with the...
