Intro to Chemistry – Size of Atoms Activities
How small is an atom? How does an atom compare in size to virus or to a plant cell? This introductory chemistry packet has a number of activities to help kids conceptualize just how small an atom is.
For the longest time in elementary, my youngest in particular had trouble understanding which was smaller an atom or a cell. This Intro to Chemistry Mini-Unit has activities to help kids understand this in a more visual way.
This Introduction to Chemistry mini-unit includes several notebook pages and activities about atoms, the size of atoms, what atoms look like compared to bacteria and viruses.
There are a number of activities that will help students to understand size and scale while comparing atoms, DNA, viruses, cells, frog’s eggs and other things up to the size of mice.
It can be challenging for kids to understand and conceptualize difference in size between atoms, cells and other objects. An atom is the smallest unit of a chemical element and a cell is the smallest unit with the basic properties of life. This packet helps kids explore the relative size of atoms compared to other larger cells and organisms.
This packet begins with a basic introduction to chemistry. We talked about how Greek philosophers thought about matter and proposed the idea of an indivisible particle called an atom. In the 1700s scientists learned more about atoms and in 1803, John Dalton proposed the Atomic Theory, the idea that all matter is made of atoms.
From there, we talked about the size of an atom. One quick activity includes illustrations of atoms and molecules, viruses, bacteria and other cells. Students have to pick out the pictures of atoms and molecules. Illustrations don’t tell us much about the relative size of these particles. The next Size Comparison Activity is designed to help understand just how small an atom is.
It also introduces students to some really small measurements – the nanometer and micrometer.
The final page introduces students to elements and the periodic table.
There are several notebook pages. The student pages are fill-in-the-blanks. There are full-text pages which the instructor can use (or if your family prefers, your students can read through the full-text pages instead). You do not need any outside sources or books with this packet. This Introduction to Chemistry Packet will take just a few days to complete.
What age is this material for? This is probably most suitable for upper elementary and middle school students, though younger students could certainly arrange the objects in order and participate with siblings.
This material is also available in our Chemistry Bundle Options. See the Chemistry Page for more details!

This 100+ page Properties of Matter packet covers:
- Elements & Compounds
- Organization of the Periodic Table (on a very basic level, our Chemistry Unit goes into *much* more detail on that!). In this unit there is just one page on that.
- Molecular vs. structural formulas
- Physical and Chemical Properties
- Basic definitions (of terms such as viscosity, elasticity, capillarity, ductility, malleability, etc.)
- Hands-On Activities of some of these properties (viscosity, cohesion, capillary action, etc.)
- Density Activities
- Mixtures: Solutions, Colloids and Suspensions
- Separating Mixtures
- Review Materials
- Building Molecules
Electricity & Circuits Unit – (suggested for grades 5-8) This is a fun, hands-on unit! My daughter did this in 6th grade and really loved it!
Chemistry Packet: The Periodic Table
150+ Page Chemistry Packet!
The Chemistry Unit is more than 150 pages and goes into detail about the periodic table, valence electrons, periods, groups, Lewis Diagrams, and basic vocabulary such as ions and isotopes.
Students are introduced to the structure of the periodic table, Bohr Diagrams, Lewis Diagrams and electron configuration in a fun, hands-on way! There are also booklets for students to become familiar with the first 20 elements and elements with unusual names.
I would do the Chemistry Unit after the Properties of Matter Unit.
This booklet had my daughter find out: the atomic number, atomic weight, period and group numbers. Plus, there was some space for her to write some basic facts about each element.
Some of the topics we explored in the Chemistry Unit include:
- Building the Periodic Table
- Bohr Diagrams & Understanding Valence Electrons
- Periods, Groups & Families
- hydrogen & the alkali metals, alkaline Earth metals, halogens, noble gases
- Atomic Number, Atomic Mass & Chemical Symbols
- Lewis Diagrams
- Metals, Metalloids and Nonmetals
- Unusual Element Symbols
- Trends of the Periodic Table
- Electron Configuration
Recommended for chemistry:
Molecular Model Kit: We have had our Molecular Model Kit on hand from the time the kids were pretty young. We used it multiple times a year… building everything from water and carbon dioxide molecules to glucose or methane, ethane, propane, etc. (depending on what we were talking about!) I recommend you get one that has at least 12 (white) hydrogens, 6 (red) oxygens, and 6 or more (black) carbons — I highly recommend this kit (for any time) but especially if you do the Physical & Chemical Properties of Matter Unit and/or the Chemistry Unit.
Pathogens – Viruses, Bacteria and More!
The Pathogens Packet is not included in the Chemistry Bundle (it is included in the Biology Bundle), but would go well with the Introduction to Chemistry – Size of Atoms mini-unit.
$8.99 Pathogens Packet (100 pages) – This unit covers the six major living and nonliving pathogens: bacteria, protozoa, fungi and parasites/worms as well as viruses and prions. The large majority of this packet goes into detail about bacteria and viruses. See more information about the Pathogens Unit here.
