Use this resource to have your class learn about the cell. This resource walks learners through the construction of a model of a cell. This project is completed in a cooperative learning group, and  reinforces the higher-order...

Will human population growth always be exponential, or will we find a limiting factor we can't avoid? Young scientists learn about both exponential and logistic growth models in various animal populations. They use case studies to...

What an eccentric way to learn about each level of cellular organization! Allow emerging biologists to utilize white paper and create their own foldable charts to describe each level of organization in the body. You may also adapt the...

Providing a higher-level thinking experience, this presentation provides an in-depth and interesting review of mammals. The terms used in the presentation give students a chance to be exposed to scientific classifications. There is also...

If pupils think the three types of rock are classic, punk, and hard, these puzzles offer gentle correction. Scholars match the type of rock to how it formed and an example in four grid puzzles. Each requires problem-solving and...

You might not be able to learn through osmosis, but you sure can observe it! Scholars observe and measure osmosis using chicken eggs. They control for multiple variables to determine which variables have an impact and how the impact...

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...

Why are car manufactures required to install seat belts and airbags; do they really make that big of a difference? Scholars use a simulator to determine the amount of force dissipated by a seat belt and airbag in a head-on crash. This is...

Many types of cancer treatments now depend on nanotechnology—a big "little" discovery. Scholars begin by removing "malignant" tissue from simulated brains, one using fluorescent markers thanks to nanotechnology and one without. This...

How is energy transferred within an ecosystem? What would happen to a food web if one of the organisms was removed? Elementary or middle school ecologists examine these questions and more in a comprehensive 5E learning cycle lesson....

If you are looking for a great way to present natural selection in humans, look no further. This handout is intended to accompany the 14-minute video The Making of the Fittest: Natural Selection in Humans, which can be found on the...

Titration calculations require concentration. The 10th lesson in an 11-part series challenges young chemists to use titration in order to determine the molarity and mass percent in concentrated vinegar. Analysis questions encourage...

Kids act as scientists and preditors in this short natural selection activity; they collect and analyze data, then apply their new knowledge to real-world examples of natural selection. The layout of the worksheet is easy enough to use...

What better way to study the structures of organisms than by creating a new being? After considering different types of skeletal supports (exoskeleton and endoskeleton), budding biogeneticists work together to create their own animals -...

Being an astronaut takes not only high mental acuity, but also a high level of physical fitness, especially for those who spend a long amount of time away from Earth, such as the astronauts serving on the International Space Station....

Many people know that fiber optics are used in delivering the Internet, but are surprised to learn they are also used in astronomy. Scholars explore light, reflection, and fiber optics through hands-on activities. They discuss...

Can a small change in laboratory procedures save energy? Scholars test three different methods for heating water in a science lab. Then, they calculate the energy efficiency for each and compare them to determine which uses the least...

If you are looking for worksheets about alternative energy sources to use on Earth Day, you'll find several here. However, since Earth Day is all about conserving natural resources, please print these double-sided in order to reduce the...

What are the three types of energy a ski jumper uses? If you said potential, kinetic, and heat, then you are correct. Scholars adjust the jumper's mass, jumper's form, and height of the start line in the simulation to display graphs of...

Can you easily lift more than your own weight? With a pulley system, almost anyone can manage this challenge. Scholars adjust the mechanical advantage (number of pulleys), weight of object being lifted, and the length of rope pulled. The...

What are some simple uses for an electromagnet? Scholars explore the electromagnetic circuitry in a doorbell through an interesting simulation. They control the core material, number of loops, amount of current, and strength in a spring....

What does your DNA actually look like? Use simple materials with this experiment to find out! Geneticists of all ages can follow these instructions to extract their own DNA. For learners who are hoping to extend the activity, there are...
