We’re doing an easy sink or float orange density experiment for kids. Also, look at my page 4 Weeks Free Physical Science Unit Study & Best Hands-on Ideas for more activities.
The sink or float orange density experiment is an easy activity that helps kids grasp important science concepts in a hands-on way.
Plus, it’s a hands-on way to introduce other scientific methods like predicting, testing, observing, and analyzing results.
After the experiment, your child should be able to understand that the density of an object determines whether it floats or sinks.
But what is density? First, talk about the misconception that that heavy things sink and light things float.
There must be something more to sinking and floating than size or weight.
So density means the relationship between the mass of the substance and how much space it takes up (volume).

10 Books About Physical Science
Physical science varies in topic. It can cover states of matter, forces and motion like push and pull, forms of energy like simple circuits, light and sound to earth and space.
Can you make an ice cube disappear? Put it on a hot sidewalk. It melts into water and then vanishes! The ice cube changes from solid to liquid to gas. This Level 2 Let's-Read-and-Find-Out picture book is a fascinating exploration of the three states of matter. This clear and appealing science book for early elementary age kids, both at home and in the classroom, uses simple, fun diagrams to explain the difference between solids, liquids, and gases. This book also includes a find out more section with experiments designed to encourage further exploration and introduce record keeping.
In Matter: Physical Science for Kids, kids ages 5 to 8 explore the definition of matter and the different states of matter, plus the stuff in our world that isn’t matter, such as sound and light! In this nonfiction picture book, children are introduced to physical science through detailed illustrations paired with a compelling narrative that uses fun language to convey familiar examples of real-world science connections. By recognizing the basic physics concept of matter and identifying the different ways matter appears in real life, kids develop a fundamental understanding of physical science and are impressed with the idea that science is a constant part of our lives and not limited to classrooms and
laboratories
Why did Gandhi hate iodine (I, 53)? How did radium (Ra, 88) nearly ruin Marie Curie's reputation? And why is gallium (Ga, 31) the go-to element for laboratory pranksters?The Periodic Table is a crowning scientific achievement, but it's also a treasure trove of adventure, betrayal, and obsession. These fascinating tales follow every element on the table as they play out their parts in human history, and in the lives of the (frequently) mad scientists who discovered them. The Disappearing Spoon masterfully fuses science with the classic lore of invention, investigation, and discovery.
Jeanne Bendick, through text and pictures, admirably succeeds in bringing to life the ancient Greek mathematician who enriched mathematics and all branches of science. Against the backdrop of Archimedes' life and culture, the author discusses the man's work, his discoveries and the knowledge later based upon it. The simple, often humorous, illustrations and diagrams greatly enhance the text.
Charles Ludwig retells Michael Faraday’s remarkable life story in fictionalized form. Here is the father of the electric motor, the dynamo, the transformer, the generator. Few persons are aware of the brilliant man’s deep Christian convictions and his determination to live by the Sermon on the Mount. For ages 12 to 15.
Book about electricity for children.
Did you know that energy comes from the food you eat? From the sun and wind? From fuel and heat? You get energy every time you eat. You transfer energy to other things every time you play baseball.
Have you ever wondered why a prism turns ordinary sunlight into a rainbow? Isaac Newton knew why. How can a magnet be used to generate electricity? Michael Faraday could have told you. Can you explain how a toaster toasts bread? In this book, author Paul Fleisher answers these and many more questions as he looks at the laws that describe how waves behave. Through simple experiments, detailed illustrations and concepts that are easy to understand, readers are introduced to the basic principles of light, electricity and magnetism in a fun, exciting way.
Have you ever wondered why a 10-tonne boat floats but a tiny pebble sinks? Archimedes knew why. How does a basketball or tennis ball bounce? Robert Boyle could have described how! Can you explain why a hot-air balloon rises but a balloon you blow up drops to the ground? To answer these questions and many more, author Paul Fleisher explains the laws that define how and why liquids and gases behave the way they do. Through simple experiments, detailed illustrations and concepts that are easy to understand, readers are introduced to the basic principles of fluid mechanics in a fun, exciting way.
Explains the concepts of simple and complex machines and mechanical advantage, and describes how wheels, including gears and ball bearings, work

ORANGE SINK OR FLOAT EXPERIMENT
First, look at this easy list of supplies for the wow factor.
- 2 mandarin or naval oranges
- 2 containers. Use glass for better visibility.
- water
First, gather all supplies needed.
Fill both containers with water but leave room at the top to prevent them from overflowing when the oranges are introduced.
Peel one orange and leave the other orange unpeeled.
Then place the unpeeled orange in one container.
Place the peeled orange into the other container.
What are the results?
Why does this happen?
When an orange is placed in water with the peel still on it will float.
It floats because the peel has air pockets making it less dense than the water.
Imagine the peel as a little lifejacket for the orange.
A peeled orange will sink because the peel is removed making the orange denser than the water.
