We learned that matter is made of atoms which are very small and the Atomic Theory is a scientific explanation of the structure of atoms and how they interact with other atoms. We learned that atoms have a dense nucleus made of protons which have a positive charge and neutrons which have no charge. Outside the nucleus there are negatively charged electrons speeding around in an area named the electron cloud. We learned that there are many kinds of matter and an element is the type of matter made of just one kind of atom. Then we learned that all known elements are organized by their properties in the Periodic Table of Elements. Next we learned that different atoms of the same element can contain different numbers of neutrons and electrons can be gained or lost but the number of protons in an element always stays the same. This is why elements in the Periodic Table of Elements are given an atomic number equal to the number of protons.

Animalia II,
Jayne wanted to finish the Animalia search puzzle. We examined each page and found new words and different ways to interpret the images. She gave me some information about her favorite animal (unicorns) and I showed her about the real unicorn (narwhals).
We learned that atoms go through chemical changes with different types of atoms that can cause molecules to change the way they are put together forming new compounds. Then we learned that compounds can have different properties from the elements that formed them. We learned the structure of the Periodic Table of the Elements. Then we learned about the chemical bonds between elements in compounds. We learned that most of the time atoms do not travel alone. Atoms bond with other atoms to make molecules. When atoms bond with all the same type of atoms, they are called elements because they are purely one type of atom. Sometimes different kinds of atoms bond together. When this happens a compound molecule is formed. Chemical formulas are a simple shorthand chemists use to indicate the type and number of atoms in a molecule. Next we learned that atoms are limited in the number of bonds they can make. Chemists use the “HONC” rule to remember the maximum number of bonds for Hydrogen, Oxygen, Nitrogen and Carbon. Hydrogen can make one bond, Oxygen two, Nitrogen three and Carbon four.

Animalia,
Jayne and I read the book Animalia, by Graeme Base. This book presents, with exceptional artwork, the alphabet, with a single letter per page. Each page is alliteration taken to the extreme with hundreds of items for the reader to find, all with names that start with the associated letter. Jayne was tasked with finding the drawing of a boy, which is incorporated into the artwork for each letter. While searching for the boy, we expand our vocabulary by finding the hidden treasures.
