For this colliding asteroids worksheet, students are given the equation to determine the collision time for asteroids. Students use this equation to solve 4 problems including finding the area of a cross-section through the body of an...

In this modeling a planetary nebula worksheet, students use a diagram to calculate the intensity at different radii from the center of the nebula. Students use the Pythagorean Theorem to determine the distance between two points on the...

Students examine the relationship between land development and the environment. In this environmental stewardship lesson, students explore how population density, land development, transportation, and impervious surfaces take their toll...

Students explore density, mixture and solutions in a reaction. In this chemistry lesson, students create their own chap-stick using ingredients they analyze for their chemical contents. They discuss measuring skills, melting points and...

Students study the water cycle and how the sun is an important factor.  In this water cycle lesson students investigate how to desalinate water and explore the different densities of fresh versus saltwater.

Students demonstrate how ocean currents are influenced by changes in density. They discover that temperature and salintiy affect density as well. They participate in a short experiment to end the activity.

Learners explore an estuarine system to gather data on density driven currents. This type of current is contrasted with temperature and wind driven currents.

Since light travels faster than sound, some people may appear bright until you hear them speak. The presentation covers what sound is, how fast it travels in various mediums, properties of sound, hearing, and the parts of the human...

Students explore the economic, political, racial, and religious roots of Manifest Destiny. They read articles and analyze how the concept influenced the nation's westward expansion. Students discover the motivations and expectations of...

Students explore the concept of Manifest Destiny. In this Westward Expansion instructional activity,students examine primary and secondary, print and nonprint sources regarding the removal of the Cherokee.

Your young chemists will find these slides very informative. Groups and periods of the periodic table are labeled and described according to the charge. Comprehensive explanations of physical and chemical properties and how they relate...

Salinity is the focus of two experimenters that work to answer the question, How does salt change the physical properties of water? Super scientists compare the freezing rate of salt and fresh water, combine the two waters to...

Don't just sink the boat. Using a closed container as a submarine, pupils experiment to see what to add to the container to make it float, sink to the bottom, and hover in the middle. After finding one option, learners see if they can...

Hand your incoming scientists a collection of helpful worksheets to introduce them to your chemistry class. The packet addresses exponents, scientific notation, metric conversion, and dimensional analysis.

It's electronic! Pupils uncover elements and their electron configurations as they explore mass, groupings, correct charges, and sliding theory. Young scientists learn creative ways to remember various elements and correctly...

Science rocks! Explore three types of rocks and the rock cycle with an igneous rocks experiment. Pupils discuss textures, composition, and learn how melts are formed from the Earth's crust. They weigh materials using a scientific scale...

Introduce your class to storage tank failures caused by major storms with an activity that looks at how the concepts of Archimedes' Principle and Pascal's Law affect the storage tanks along the Houston Ship Channel. The background...

The challenge: determine whether a tank will float. A design activity has groups work as engineering teams in order to determine the stability of given tanks and liquid contents. The teams need to determine the equations to...

Groups use a marble to determine the viscosity of household fluids. The procedure calls for pupils to measure the amount of time it takes a marble to fall a specified distance in the fluids. Using unit conversions and algebra, the teams...

Wolves eat better when the bunny population increases, but how long does that last? A series of 12 biology lessons uses the sixth installment to explore the predator-prey relationship between bunny and wolf populations. Young scientists...

How can people control a hot air balloon? The simple simulation allows scholars to adjust the payload mass, burner, and vent position on a hot air balloon and observe the changes in velocity and altitude over time. Challenge questions...

Why does the air in a hot oven not burn skin, but metal in the oven does? The simulation focuses on the difference between temperature and thermal energy and the way these are transferred. Scholars adjust the temperature of an oven and...

Air, air, everywhere, but what's in it, and what makes Earth's air so unique and special? Journey through the layers above us to uncover our atmosphere's composition and how it works to make life possible below. Pupils conduct...

Sometimes scientists learn more from unexpected findings than from routine analysis! Junior oceanographers dive deep to explore hydrothermal vent communities in the fourth lesson in a series of five. Scholars examine data and look for...
