We don't think of liquids as floating typically, but a quick look at any oil spill tells a different story. Lesson explores various densities of liquids and why this fact is important. After observing the density variation, scholars...

The first golf balls were made of wood and would only last for a few games. Modern golf balls last a lot longer but they don't float. The presentation provides the directions for a lab to determine the minimum amount of salt needed to...

Students assess human impact on water quality. They determine how the force of friction retards motion. Pupils describe and measure quantities that characterize moving objects and their interactions within a system: Time, Distance,...

High schoolers measure the length, width and height of different materials.  In this design lesson students complete a lab to see what engineers need to consider when planning a structure.

Students find the mass, volume, and density of various objects. In this density measurement activity, students observe how same-sized objects can have different masses, then use water displacement to find the density of each object and...

Ninth graders develop operational definition of density, do computations using density equation, categorize pieces of matter as being able to float on water or not, based on density, explain why some objects sink or float based on...

In this parallax effect worksheet, students observe 2 photographs taken of an active area of the sun by 2 STEREO satellites and 1 photograph taken of the same active area of the sun by the SOHO satellite. Students observe the shift in...

In this solar storms worksheet, students read about the correlation between different astronomical events to find patters and new 'laws' of nature. Students use given statistical information about solar flares and coronal mass ejections...

Students measure respiratory rates on live toads, and the effect water temperature has on their findings.  In this scientific method lesson, students record their findings and present them in a graph, comparing the results.

Accommodate your chemistry class with an experiment that is both entertaining and educational. Through the activity, blossoming chemists perform calculations on various isotopes, as represented by beans and legumes, to obtain...

How fun would it be to teach the concept of stoichiometry while allowing your chemistry class to assemble a classic campfire treat? This fun and engaging activity allows pupils to explore the principles of the chemical theory while...

The Law of Conservation of Matter can be complex for young scientists to fully grasp. Use this experiment to help simplify the process as pupils perform two experiments to determine mass: one that melts a substance and the other that...

Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...

Three activities allow young flight engineers to understand the 4 principles of flight (weight, lift, thrust, and drag), to construct a glider, and to create a propeller. Multicultural history and literature are integrated by reading...

Mint candies are good for more than just one's breath. Using basic materials such as mint candies, straws, index cards, and Popsicle sticks, scholars create race cars that meet a given budget as well as design constraints. They perform...

Students construct the Metric Pyramid from the handout. They use the Metric Pyramid to convert from standard to metric measure and vice versa. They compute their own Body Mass Index.

Students explore the measurements of capacity by constructing a creative project in the shape of a man. The man has body parts that represent different units of measurement and can be used to make conversions. This is highly concrete and...

If a car gets heavier, it goes farther? By running an activity several times, teams experience Newton's Second Law of Motion. The teams vary the amount of weight they catapult off a wooden block car and record the distance the...

Referring to the periodic table of elements, nuclear physics learners determine the resulting elements of alpha and beta decay. Answers are given in atomic notation, showing the atomic symbol, mass, atomic number, and emission particles....

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...

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...

Too much material will weigh you down. The sixth segment in a series of 22 highlights how weight affects a plane. Pupils learn that engineers take the properties of materials, including weight, when designing something. 

Quiz your learners on density, mass, and volume with six equations. Each equation prompts kids to consider an object made of a different material, and to find the desired measurement.

All soil is not created equal! A lab activity asks learners to collect and analyze soil. Specific calculations determine the amount of sand, silt, and clay in a sample and allow individuals to identify the soil texture.
