In this lesson students will gain an understanding of what "processed" means. They will also distinguish between natural and processed foods, and learn about sources of some foods.

In this science fair project, use a refractometer to measure changes in sugar content in ripening fruit. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction, followed by a...

Sauerkraut, pickled fish, pickled vegetables, kimchi, corned beef, processed cheeses, smoked lunch meats. Do you like these high-salt foods? What about your grandparents, do they? Do your grandparents seem to like most foods to be a bit...

The goal of this cooking and food science fair project is to understand how processed cheese is made, and to determine which percentage of emulsifying salt produces the best processed cheese. The Science Buddies project ideas are set up...

This is an interesting project that explores which geometrical shapes make the strongest bridge truss structures. It is a good introduction to the engineering design process. You'll design three different trusses, and use online...

In this interactive activity adapted from NOVA, expand your understanding of the scientific process. Watch two videos featuring animations and interviews with scientists, and notice how the processes unfold and vary from one...

Experiment with designs of different hulls for boats to see which hulls are suited for which purpose. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction, followed by a...

How do scientists "copy" DNA? They use a process called the Polymerase Chain Reaction, or PCR. The key to making this process work is having a primer that will stick to the piece of DNA you want to copy, called a template. In this...

We have all heard the old saying, "One bad apple spoils the whole bunch." Due to the production of the plant hormone ethylene during the ripening process, this saying proves true. This experiment will investigate the role of ethylene in...

In this science fair project, use a calorimeter with an attached heating element to measure how water responds to added thermal energy.

This is a project that illustrates the process of natural selection in action. You'll need access to a laboratory for working with the bacterial cultures used in this project.

Many essential chemical reactions and natural biochemical processes occur in liquid solutions, so understanding the chemical properties of liquid solutions is fundamentally important. This project will challenge you to discover how much...

In this science fair project you'll discover how to turn the ocean into a source of freshwater by using the power of the Sun, and the water cycle. You will ultimately find just how salinity affects this process.

When we get hot, we sweat. The physiological role of sweat is to cool us down. When the water evaporates, it removes energy from our bodies. This sort of evaporative cooling can also be used to cool homes, using what are referred to as...

Design different hull designs for boats from milk cartons and experiment with which hull will glide the fastest, be most maneuverable, and which will support the most weight. The Science Buddies project ideas are set up consistently...

Sedimentary rock forms in layers that are deposited one after the other over long periods of time. Oftentimes, sedimentary rock contains fossils and other debris that are deposited within the layers. Use this experiment to investigate...

In this lesson plan, students learn about EarthCaches and processes of the Earth. Using online resources, they find an EarthCache located near their school, visit it, and record the information required in its associated activity. They...

Computer technology continues to develop at a rapid pace. A new home computer is noticeably faster than a machine from five years ago, and dramatically faster than a machine from ten years ago. Exactly how much faster? This project will...

Media-rich detailed description of modern cloning technology and the two different processes used: artificial embryo twinning and somatic cell nuclear transfer.

After researching how scientists drill into the ocean floor to retrieve core samples, students work in small groups to simulate the process in the classroom and report on their findings.

In this activity, you will investigate some of the processes that make water move in and out of the atmosphere by making a miniature water cycle model inside a plastic bag.

In this lesson, students will understand that in order to grow healthy plants, soil, water, light, and air must be provided. Students will use math skills such as measurement and science process skills such as observation, comparing, and...

Students who are mathematically inclined can use the student version of a program like MatLab or Mathematica to convert a digital image into numbers, then perform operations such as sharpening or special effects. This is a great way to...

Kamoku is a boy from Hawaii who is interested in the seven life processes. Do you know what these are? Join Kamoku and discover them with him.
