4th Grade Science Experiments

science experiments

Experiments is the step in the scientific method that arbitrates between competing models or hypotheses. Experimentation is also used to test existing theories or new hypotheses in order to support them or disprove them.

4th grade

Fourth grade (called Grade 4 in some regions) is a year of education in the United States and many other nations. The fourth grade is the fourth school year after kindergarten. Students are usually nine or ten years old, depending on their birthday. It is a part of elementary school.

Janice VanCleave's The Human Body for Every Kid: Easy Activities that Make Learning Science Fun (Science for Every Kid Series)

What makes the heart beat faster or slower? How do tightrope walkers keep their balance? Why does spinning fast cause dizziness? Explore the mysteries and the workings of the human body through this fascinating collection of ideas, projects, and activities. Have fun while you learn about everything from the body’s basic building blocks to how the brain receives messages from other parts of the body. Make a model of a human cell that you can eat for dessert. Make a working model of a human lung from a soda bottle, a balloon, and a garbage bag. Through these and other activities, you’ll find out how your lungs supply air to your blood and your heart pumps blood throughout your body; how your body sees, hears, feels, smells, and tastes the world around it; how you lose and regain up to five pounds of skin every year; and much more. Most of the materials you need are already part of you; the rest you will easily find around the house or classroom. Every activity has been “child tested” and can be performed safely and cheaply in the classroom, at a science fair, or at home.

Experiment bags

After the dry tests, Sabi added water to the crushed cereal to see if she could find more proof of iron in the cereal. She wrote the names of the cereals on the bags and the time that she put it in the bags to make sure that her timing was accurate!

4th grade science experiments

How do magnets work? What makes a curve ball curve? What keeps an airplane in the air? How can a pulley make you five times stronger? Now you can learn the answers to these and other questions about basic physics through 101 fun, safe, low-cost experiments and activities that can be performed at home or in the classroom. In Physics for Every Kid, you’ll learn about gravity from funnels that seem to defy nature by rolling up hill. Using a balloon as a power source, you’ll make a fluorescent light bulb glow and learn how electrons are used to produce light. And you’ll levitate a Ping-Pong ball to understand aerodynamics. Each of the 101 experiments is broken down into its purpose, a list of materials, step-by-step instructions, expected results, and an easy to understand explanation. Every activity has been pretested and can be performed safely and inexpensively in the classroom or at home.
