Rotating through five stations, evolutionary biologists explore the question of how changes in DNA facilitate the changes in a population over time. High-quality, colorful cards of animals, skeletons, skulls, and DNA sequences can all be...

Does mass change during a chemical reaction? Demonstrate the Law of Conservation of Matter while encouraging class members to be creative with a two-part lesson. First, learners use Alka-Seltzer® tablets and water to demonstrate the...

The pocket mouse can be light brown like the sands of the desert, or dark brown like the volcanic lava flows that are interspersed throughout New Mexico's Valley of Fire. It seems that predators have weeded out light colored mice in this...

Scholars analyze a propaganda poster against communism. The resource uses the poster to examine the domino theory and containment policies used by the United States to stop the spread of communism in Vietnam. Scholars work in pairs or...

How did the stickleback fish, which was once ocean bound, evolve to be able to persist in freshwater lakes? Hear from the scientists who identified the genes and related switches that allowed these survivors to adapt. In addition to the...

The hunt is on! Young mathematicians follow clues and complete a series of ten math puzzles as they try to crack Dr. Integer's code and find the location of his hidden treasure.

Mammals are some of the newest organisms to appear on Earth. Young scholars complete an activity that results in a timeline showing the appearance of different types of living organisms. Provided with a list that spans from prokaryotes...

Readers respond to a series of questions focused onJuliet Marillier's young adult novel Wildwood Dancing, and crafted to reflect the levels in Bloom's Taxonomy.

Bubbles aren't just for children. In the third installment of a seven-part series, teenagers use bubble solution to create bubbles and observe patterns of refraction on the bubble surfaces. Application of this concept to thin films in...

Stephen Perry invented and patented the modern rubber band in 1845. Young scientists put his discovery to work as they use rubber bands to observe entropy and enthalpy. They determine the change in free energy to figure out if it...

How important is momentum? Pupils investigate and apply the definition of momentum as they conduct analyses during a series of one-dimensional collisions. They infer the relative masses of two objects by carefully staging and predicting...

How did relations between the United States and the People's Republic of China evolve between 1950 and 1970? Your young historians will complete a timeline of events with evidence that the relationship between these two great...

In a fun and interactive two-day lesson, learners sort anole lizard pictures by appearance. Next, they watch a video about the anoles and re-sort based on the information in the video. In addition to physical characteristics, budding...

What adaptations exist in order for icefish to survive the subfreezing temperatures of the Antarctic Ocean? Middle and high schoolers can find out through watching a related 13-minute video and performing a simple investigation to...

What's the link between lactase persistence and dairy farming? Biology scholars analyze data to find evidence of the connection, then relate this to human adaptation. Working individually and in small groups, learners view short video...

My room isn't messy — it's a scientific experiment in entropy! Scholars investigate entropy, enthalpy, and spontaneity through a guided procedure and set of questions. The lesson connects the Second Law of Thermodynamics, energy...

A 15-page package thoroughly teaches your physics or astronomy learners about Kepler's three laws of planetary motion. Each one is stated and explained. Class members answer questions, solve problems, and participate in the classic...

What is it that makes people keep going when they face challenges in life? Ask your class to consider this question in relation to their own experiences and as they read material from The New York Times. Using personal experiences...

Get into the swing of things. Pupils use a pendulum to demonstrate the conversion of potential energy to kinetic energy and back. After measuring the speed of a pendulum and compare it to the calculated theoretical speed, they...

Does it feel a little humid in here? Learners assume the role of water vapor in the atmosphere as they explore the differences between warm and cold air. They roll dice to determine their level of energy, which determines if they...

Earth historians research a specific dinosaur, write a paper about the Mesozoic era that it lived in, create an artistic rendition of the environment, and give a presentation in class about what they learned. Be aware that there are...

In this solar storms worksheet, students use an on line source to read newspaper stories about scientific theories and hypothesis related to space weather phenomena. Students answer 7 questions about past solar storms and compare ideas...

Probability prevails in this assignment as youngsters determine the probability of finding a blue pen in a cereal box when they can come in blue, green, yellow, or red. Learners set up a simulation to determine the outcome of compound...

Why is the weather man wrong so often? Young climatologists discover how chaos rules both weather and climate through a math-based activity. Using an iterative equation, the class examines how small day-to-day weather events total up to...
