Before Isaac Newton became the father of physics, an accomplished mathematician, or a leader of the scientific revolution, he was a boy living in an apothecary's house, observing and experimenting, recording his observations of the world in a tiny notebook. As a young genius living in a time before science as we know it existed, Isaac studied the few books he could get his hands on, built handmade machines, and experimented with alchemy.

Just looking at the periodic table can be enough to give young science students a serious headache. But as you’ll soon find out, all those mysterious numbers and letters are clues to the amazing world of elements. The brainchild of Siberian superchemist Dimitri Mendeleev, the periodic table represents the 111 known elements, from hydrogen and oxygen to nobelium and lawrencium. But this doesn’t mean there are only 111 elements in the universe.

Chemists are kind of like detectives. They do a lot of research and conduct experiments to find out new information. If an idea has not been proven yet, a chemist will need to make an educated guess called a hypothesis. Kids will learn what a hypothesis is and how a hypothesis can become a theory. Fun music and engaging lyrics will have future chemists learning about making an educated guess.

How are balloons able to float? Is it magic–or is it one of earth’s elements, like iron or oxygen experiencing an explosive charge? Helium is formed when unstable atoms collide. Helium is found underground with other gases, like methane, which is the main ingredient in natural gas used to heat our homes! Learn how helium was born, and how exploding stars helped create a gas lighter than air!

What do all the things you can see and touch in the universe have in common? Atoms! Made up of electrons, protons, and neutrons, atoms are so tiny you can’t see them without special microscopes.

There are many types of sugar used in the foods we eat. To stay healthy, we can't consume too many of those pesky added sugars!

Sugar and salt look a lot alike. Kids will learn that the reason sugar and salt look the same but taste very differently is that they are made up of different elements. Kids will learn about the periodic table and that when different elements are joined together, they make different things. Fun music encourages young learners to explore this fascinating concept.

Kids will learn that scientists call the smallest part of anything an atom. Anything you see at all in the world that takes up space is made up of atoms. Fun music and engaging sound effects will teach young scientists about tiny particles called atoms.

Fun music and engaging lyrics will help kids learn important terms used in the science of chemistry including: hypothesis, atoms, elements, compounds, mixtures, condensation and evaporation. Perhaps you will a member in the Future Chemists’ Club when you grow up. The occupation of a chemist is fascinating.

Do you like math and science? Do you like to conduct experiments in science class? If so, then you might want to become a chemist someday. What exactly is chemistry? Chemistry focuses on chemical substances and how they interact with each other. Kids will love this upbeat audiobook guaranteed to make them interesting in learning more about becoming a chemist someday.
