An interesting approach to science projects where students are challenged to create complex machines that do very simple jobs, e.g., opening a door. Offers four ideas for projects.

Provides detailed instructions for how to help a student make a solar system model, and additional suggestions for making a constellation poster, making a model showing phases of the moon, and creating a solar system model to scale.

In this engineering science fair project, students will determine the most effective method for quickly raising the temperature of a liquid in a tank. The Science Buddies project ideas are set up consistently beginning with an abstract,...

In this human behavior science fair project, the student will investigate whether packaging can persuade children to eat healthily. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and...

In this project you'll learn how to make a piezoelectric pickup for acoustic guitar using inexpensive components. You can then connect your acoustic guitar to an amplifier, and record your own music. If you are interested in electronics...

Egg allergies are not uncommon, therefore many egg substitutes are sold in order to bake, and cook recipes that call for them. In this science project idea, you'll investigate how to modify recipes so that even egg-allergic friends and...

A list of 50 ideas for science fair projects for Grade 7.

Here's a project with practical applications for homes with a wireless network. This project shows you how to build and test parabolic reflectors for the transmitters on your network. You may be able to increase the range of your...

The element lead is a neurotoxin that is particularly dangerous to young children. Among other uses, lead compounds were common paint additives until being phased out for safer titanium-based additives beginning in the 1960's. Lead...

Here's a project where you can try your hand at being a detective with your computer. In this project you'll write a program to do some basic analysis of features of written text (for example, counting the length of each word in the...

Find out the real explanation for why your parents are so weird. Here is a project that lets you explore the internet to find out why your "DNA blueprint" is so important to health and disease. In this project you will use methods that...

If you like to bake, this could be a good project for you. There is a purpose for each of the ingredients in your recipes, but not everyone is always aware of what that purpose may be. Though this lab takes multiple days, you will...

There's nothing quite like the smell of fresh-baked muffins for breakfast on a Saturday morning. If you're into baking, you might want to try this insightful project that lets you witness the chemistry behind making muffins. You'll get...

In this week long "kitchen chemistry" project you will use chemicals from the supermarket to test for the presence of iodine and iodide in salt. These are common micronutrients added to some preparations of table salt. A materials list,...

In this project you'll learn a method for measuring how much chemical energy is available in different types of food. You will build your own calorimeter to capture the energy released by burning a small food item, like a nut or a piece...

In a bioassay, a living organism serves as a detector for toxins-the same way canaries were used in coal mines to detect invisible toxic gases. In this project, water fleas (Daphnia magna), a freshwater crustacean, are used in a bioassay...

What covers less than 10% of the Earth's surface, yet is a vital natural resource for terrestrial life? What filters ground water and supports most of our food production, not to mention the production of building materials and paper?...

Water is a valuable resource many often take for granted. This exercise however gives you the opportunity to learn about and discover how greywater (water that has been used for washing or bathing) can be used for watering ornamental...

Imagine yourself as a software engineer, a decade and a half from now. You are called upon to help solve the world energy crisis by programming nano-organisms (NANORGs) to extract energy from industrial sludge. Your program must be small...

In this science project, you will investigate the secrets of your distant past as revealed by your DNA. In order to obtain a sample for DNA analysis, you will scrape a soft swab inside your mouth to collect cheek cells. Based on the...

Descriptions of five experiments and a list of other ideas for possible science fair projects for Grade 7.

Physical activity is needed for maintaining normal bone strength and mass. But whether physical stress on finger bones during development leads to an increase in finger length, is something you will discover in this project not by...

Imagine that a biologist arrived at your big family reunion and had no idea who were sisters, cousins, aunts, uncles, etc., but tried to sort it out by how all of you look. Just based on how you look, would s/he be able to guess whether...

In this two week long project, you will design an assembly-language control program for the microprocessors of a colony of nano-organisms (NANORGs) in a virtual world. If you're up for a real programming challenge, this is the project...
