How do you teach the periodic table at home? A free 4-week homeschool unit
A homeschool periodic table unit works best as four short weeks: meet the elements, learn the first 20, see how elements join into compounds, then explore the patterns in the table. Each day is 15 to 25 minutes, and every week ends with a game day. Everything below is free, apart from household items you probably already have.
The plan is written for elementary kids, and it's easy to stretch for an older sibling. It slots in beside a full science curriculum or works as a stand-alone unit.
What will your kid know by the end?
- What an element is, and that the periodic table lists all 118 of them.
- The first 20 elements by name and symbol, with one real-world fact for each.
- That compounds, like water and salt, are elements joined together.
- How the table is organized: rows, columns, metals on the left, nonmetals on the right, and the noble gases at the end.
What do you need?
- A printed periodic table (any free one is fine).
- The free Elemon element cards 1–20, printed on card stock if you can.
- The free periodic table bingo cards.
- A device with a web browser for game days.
- Everyday items for element hunts: aluminum foil, a pencil, table salt, chalk, a balloon, copper wire, baking soda and vinegar.
- A notebook for an "element journal."
Week 1: What are elements?
The goal this week is the big idea: everything is made of elements, and the periodic table is the list.
- Day 1: Read what the periodic table is, explained for kids together. Find hydrogen, oxygen and gold on your printed table.
- Day 2: Element hunt. Find five things at home made mostly of one element (foil, a pencil's graphite, a copper wire, a balloon's helium, a silver or gold ring). Write each in the journal.
- Day 3: Pick one element card and read the back together. Draw the element in the journal with one fact.
- Day 4: Talk about states: some elements are gases (oxygen, helium), most are solids (iron, carbon), and only two are liquids at room temperature (mercury and bromine).
- Day 5, game day: Play a solo match of Elemon on Easy. After the match, ask which card was the best and what it does in real life.
Week 2: The first 20 elements
The goal is names and symbols for hydrogen through calcium.
- Days 1 to 4: Learn one chunk of five elements a day using the sentences in the first 20 elements for kids. Lay out that day's five cards in table order.
- Day 5, game day: Periodic table bingo, calling the names so your kid has to find the symbols. Then play "Atomic War" with the cards: flip one each, and the higher atomic number wins.
If your kid enjoys this part, the memorization guide has a gentle 4-week plan you can keep running in the background.
Week 3: How do elements make compounds?
The goal is that elements join into new substances with new properties.
- Day 1: Read elements and compounds, explained for kids. Water is hydrogen and oxygen, yet it's nothing like either gas.
- Day 2: Bond hunt with the cards: match hydrogen with oxygen (water), sodium with chlorine (salt), carbon with oxygen (carbon dioxide) and silicon with oxygen (sand).
- Day 3: Kitchen look: salt crystals under a magnifying glass, and the fizz when baking soda meets vinegar, which gives off carbon dioxide gas.
- Day 4: Journal: draw water as one big oxygen atom with two small hydrogen atoms, and salt as a checkerboard of sodium and chlorine.
- Day 5, game day: In Elemon, put sodium and chlorine on one team (use Choose five) and watch what the Salt Bond move does.
Week 4: The patterns in the table
The goal is reading the table's shape, the reason it's called *periodic*.
- Day 1: Color your printed table: metals one color, nonmetals another, and the metalloids in between.
- Day 2: Families. Read Elemon's nine types vs. the real element families, then sort the cards by type and by real family.
- Day 3: The noble gases (helium, neon, argon). Why don't they react? Look at neon's and argon's cards.
- Day 4: Design an element card. Your kid picks any element, researches three facts and fills in the design-your-own card sheet.
- Day 5, game day and wrap-up: A full match with Random five, then your kid teaches you three elements from their journal.
How does this fit with a homeschool science curriculum?
It's built to supplement, not replace. If you use a full curriculum such as Apologia, REAL Science Odyssey or Elemental Science, run this unit when your book reaches atoms, matter or chemistry, and use the game days as review. If you're not using a curriculum, the four weeks stand on their own as a chemistry starter.

Frequently asked questions
What age is this homeschool unit for?
It's written for elementary kids. Younger ones can do the element hunts, cards and games with you reading aloud; older kids can take on the journal, the compound drawings and the design-your-own card on their own.
How much screen time does the unit use?
One game day a week, about 15 minutes each. Everything else is cards, paper and things around the house.
Can siblings of different ages do it together?
Yes. Play bingo and card games together, and give the older sibling the harder jobs: calling clues instead of names, drawing particle models, and researching an element beyond the first 20.
