Young scientists learn that seeing isn't necessarily believing when it comes to the states of matter. After performing a fun class demonstration that models the difference between solids, liquids, and gases, children complete a series of...

Studies show that obesity is now a global problem. But how are researchers measuring obesity? Young scientists investigate the myriad of methods for measuring body fat through a presentation. From hands-on to high-tech, viewers learn...

Model and explore osmosis using squash and potatoes. Young scientists expose chunks of potatoes to different concentrations of a squash solution. They compare the weights of the chunks before and after exposure to the solution and use...

Looking for a fresh take on traditional food/energy pyramids? Conduct an innovative activity where pupils build their own! The lesson uses research data from Gorongosa National Park in Mozambique for a real-life safari touch. Scholars...

The tension of the 236 strings in a grand piano exert a combined force of 20 tons on the cast iron frame. The presentation includes topics such as work, forms of energy, conservation of energy, gravitational and elastic potential energy,...

Learners examine Boyle's Law by analyzing experimental results with a hands-on lesson that provides a set of four experiments that illustrate the relationship between pressure and volume of gases. Groups analyze results using...

In this Newton's Second Law worksheet, students answer 13 questions about force, mass and acceleration. They calculate weight, force, masses and acceleration of objects.

In this weight worksheet, students read about weight, friction, and equilibrium. Students then complete 10 matching, 7 fill in the blank, and 8 word problems.

In this experimental design and measurement worksheet, students answer questions about independent and dependent variables, they write hypotheses, they identify instruments that measure mass, weight, and volume and they calculate the...

In this force and acceleration activity, students solve 3 problems about moving objects, the forces working against them, the mass and their acceleration. Students determine if 6 statements about a falling elephant and a falling feather...

Test the limits of gravity while encouraging full class participation with this thrilling lesson. Pupils investigate the meaning of work and how it is equivalent to energy. They explore the joule and apply it as a unit of work. They...

Build an appreciation for the green movement by recycling your own paper! Learners participate in a STEM instructional activity by learning about the process of recycling paper and then designing their own models. Their ultimate task is...

Twelve pages of mostly multiple-choice questions comprise this comprehensive New York Regents physics exam. It covers an entire year's worth of physics curriculum and requires about three hours for completion. Review the questions to...

Students role play as paleontologists who make inferences about the weight of dinosaurs. They use models and the density of water to make these inferences.

In this density learning exercise, students read about density, volume and mass. They then use what they learned to answer the 8 questions on the page. The answers are on the last page.

Slide books with a little assistance from Newton. Using books, groups create a demonstration of Newton's Second Law of motion. Pupils compare the distance traveled by one and two books when they apply a force to them.

Force acts on objects in mysterious ways ... until now! A comprehensive presentation explains the balance of forces acting on objects. Learners draw free body diagrams to show these invisible forces and make force calculations.

Fifth graders study the concept of momentum and its application by Newton in his studies. They view a demonstration and complete an experiment with toy cars on a racetrack that shows them the properties of momentum and how velocity and...

Young scholars record information from the periodic table for sodium and chloride. They determine whether salts are molecular or ionic compounds, along with sodium chloride's molecular weight, and relative weights

Is obesity a disease or just a preventable risk factor for other diseases? Scholars attempt to form their own opinions by reading a background of the issue and watching videos that explore the main pro and con arguments using an included...

Learners utilize a balance scale. In this applied science instructional activity, students compare the weights of two objects using an elementary balance scale. Learners balance the scale with weights to find how heavy an object is.

In this chemistry learning exercise, students read about atoms, their charges, and their parts; protons and neutrons. They examine how to determine atomic weight by looking at an example. They work online as they practice finding the...

In this chemical reaction principles worksheet, students read about definite proportions and the law of conservation of mass. Students read about how to balance a chemical equation. Then students complete 20 fill in the blank, 2 short...

Fourth graders use a matchbox car to push across a hard surface and observe what happens. They then push the car across a soft or rough surface and discover what happens. The two ideas are discusses as Newton's First and Second Laws of...
