Long considered the symbol of safe harbor and steadfast waiting, the lighthouse gets a mathematical treatment. The straightforward question of distance to the horizon is carefully presented, followed by a look into the...

Focus on inquiry-based learning in your science class with a series of activities designed for middle schoolers. A helpful packet samples four different texts, which include activities about predator-prey relationships, Earth's axis...

Scholars examine, cut, paste, and sort 12 images featuring different types of movement in order to show what they know about energy—potential and kinetic. 

The color of the sky depends on the time of day. Young scholars experiment with scattering different wavelengths of light to recreate the color of the sky. They observe both the longer blue wavelengths and the shorter red and orange...

Did you know scientists can tell the age of an asteroid by looking closely at its craters? This final activity of a six-part series focuses on two asteroids, Gaspra and Ida, in order to demonstrate the concept of dating asteroids....

Third graders explain the basic healthy eating and physical activity concepts.  In this healthy lifestyles lesson, 3rd graders describe two main components of a healthy lifestyle, demonstrate two different types of physical...

Students, through group and individual activities, study and experiment with the concept of balance. They attempt balancing tasks at different levels of difficulty and in different body positions. They work to improve their balance.

Second graders examine human body movements by measuring the choreography of a dance.  In this physical education instructional activity, 2nd graders participate in a creative dance which is based on specific movements of each limb,...

You can teach Bocce ball to most age levels. The biggest concern with younger players is safety; they need to learn how to throw the Bocce balls without inadvertently hurting another player. The focus in this lesson is how to generate...

The amount of energy Americans use doubles every 20 years. The first lesson in a 10-part series teaches scholars about different forms of energy. They rotate through five stations with hands-on activities or experiments at each in order...

Students determine the density of different substances. In this physical science lesson plan, students rank them according to their density. They discover the relationship between volume and density.

Students examine the basic concepts of advertising.  In this media awareness lesson, students discuss target audience, art, and purpose in advertising to determine what makes an advertisement effective or ineffective. ...

Fifth graders roll different sized cans down an inclined ramp in order to determine if the contents of a can affect the speed at which is rolls. In this physics lesson, 5th graders work in small groups to send each can down the ramp...

Explore gravity, force, and mass as some of the natural forces in the universe. Each slide provides information and examples that describe each concept. Learners are encouraged to throw a basket ball and a bean bag into the air to...

Many physicals include a blood glucose test, but what are doctors actually testing? Scholars graph and interpret blood glucose data, allowing them to observe the differences in lactase persistence and draw conclusions. They then connect...

Why do sprinters wear spiked shoes? Scholars explore various styles of shoes and how they handle forces when running. Scholars adjust variables including shoe type, horizontal force, surface type, and normal force to determine which...

This worksheet would make a nifty quiz on the laws of thermodynamics. Nine multiple choice questions assess high schoolers' understanding of energy transfer, specific heat capacity, phase change, fusion, and vaporization. It is short but...

Probability, especially conditional probability, can be a slippery concept for young statisticians.  Statements that seem self-evident on the surface often require a daunting amount of calculations to explicate, or turn out to be...

Surprise! is the theme of this series of ESL lessons. Cover an array of topics such as where we live, different times of day, shapes, the city and the country, what we do for fun, jobs, and games, all while practicing how...

Students examine physical change with different temperature and solvents. In this elements and compounds lesson, students conduct experiments to discover what happens to the mass of a substance when is undergoes a physical change.

Students use the internet to discover the basic concepts in physics. They complete interactive simulations where variables can be changed. They answer comprehension questions to end the lesson.

Students comprehend that a chemcial change produce substances with a different composition and physical and chemcial properties. They state the differences between physical and chemical changes. Pupils observe changes that occur during...

Students investigate different liquids to develop their concept of a liquid. They work at a center to tip, swirl, shake, roll, and otherwise investigate seven liquids in small, clear plastic bottles: plain water, corn syrup, liquid...

Young scholars track species using the Journey North project. They examine the meaning of physical and behavioral adaptation, migration, and identify adaptations that help the species they track survive.
