Assist your middle school class with one of the most inclusive weathering and erosion labs available. Individuals use sugar cubes and alka-seltzer to demonstrate the process of physical and chemical weathering. They sketch results...

How do Olympic runners succeed in physically demanding events like the 400-meter dash? Physiology scholars explore the relationship between acids, bases, and the muscular system through a scenario-driven activity. The lesson focuses on...

Model the transfer of energy during a typical 24-hour period. Young scholars use a game-like approach to learning the patterns of heat transfer through the day and night. Groups of four exchange different tokens as the energy...

Lesson 19 in the series of 36 analyzes the element hydrogen and the s-block elements. Through readings, answering questions, and discussion, learners write about and explain their occurrence, physical and chemical properties, and...

Between the time scientists discovered Pluto and reclassified it as a dwarf planet, it did not even make one full revolution around the sun. In two activities, scholars investigate scale models and their properties. Pupils find that it...

Weathering is not necessarily a result of the weather. Scholars conduct an experiment to explore the effect of surface area and volume on the weathering process. They create their own sugar cube rocks using the same number of cubes—but...

Here is part one of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas. With grand conversation and up to three demonstrations, learners make predictions about what they think will happen...

Explore the world (our world) of melting ice caps. Why are these caps melting? What is the effect of melting ice caps? Dive into the ever-present issue of global warming with a resource that has learners looking at data and participating...

Scientists need to figure out how to measure interplanetary magnetic fields, but the magnetic field of the spacecraft is interfering with their readings. Scholars attempt to solve the problem that has perplexed NASA scientists for years.

In this chemical reactions worksheet, students experiment with hydrochloric acid and copper (I) chloride to identify the types of reactions they undergo with various other substances. They also observe the law of conservation of mass and...

Student groups rotate through four stations to examine light energy behavior: refraction, magnification, prisms and polarization. They see how a beam of light is refracted (bent) through various transparent mediums. Students investigate...

Students become familiar with the variables that control Earth's solar energy supply. They explore the source and nature of solar energy, the genesis of radiation, and the structrue of the Sun, gas spectra are observed and sample...

Students examine mechanisms behind biological evolution and the theories that feed it, and are able to demonstrate their knowledge of these theories in a story.

Teens often display potential energy in class and kinetic in the hallways. This third presentation covers the six types of energy, each in potential and kinetic form. It also covers the Law of Conservation of Energy and Einstein's...

Students identify what and how to complete an Archaeological excavation is conducted. They identify the transition from one layer to the next more easily if the colors of the layers are different. When creating a dig, the teacher...

Middle schoolers build a Colossal Classroom Cladogram of vertebrate evolution. After putting it together, they show the gradual, mosaic accumulation of the traits which we, as humans, possess.

Not only do future engineers learn the difference between accuracy and precision, they also get some hands-on experience using different measuring tools. 

Emerging nutritionists explore what it means to be healthy. In the beginning of the unit, your class will examine the five food groups and learn how food gets from the farm to our plates. This leads into the investigation of...

Students experience a "hands-on" activity to get visual evidence of the physical nature of DNA and the process of DNA purification. They explore one method of chromosomal DNA isolation and DNA extraction.

Add a little music to your next physics class. Pupils discuss how frequency determines pitch and take part in several activities designed to teach them more about sound, melody, resonance, and vibrations. They use materials to construct...

You've probably spent plenty of time discussing animal adaptations with your young biologists, but what about human adaptations? Explore the evolving traits of humankind through an interactive that combines text and video clips. Scholars...

Is it really that big of a deal if the global climate undergoes a little change? Young environmentalists consider this very question as they discuss in small groups the impact of different climate change scenarios on their lives,...

Youngsters examine resource maps to find out which states are using solar and wind power and discuss as a class various other renewable energy sources. They use a provided data table to record pros and cons to each technology, build and...

Assist your class with correctly calculating the values for force, work, and power as they determine the amount various activities require. They gather data and participate in a group discussion to compare results upon conclusion of the...
