Periodic Table Activity: 8 Hands-On Stations for Identifying Atoms in Chemical Reactions (TEKS 8.6B)

Chris Kesler · 8 min read

Many 8th graders can recite some of the elements on the periodic table. Far fewer can actually use it. Ask them which elements would react with each other, or why sodium and chlorine end up in the same compound, and you'll get the same blank stares you got when you taught them matter classification.

The periodic table isn't a chart to memorize. It's a tool that predicts behavior. The trick is helping kids see the patterns themselves rather than just labeling rows and columns on a worksheet.

The Periodic Table & Reactions Station Lab for TEKS 8.6B does that in one to two class periods. Hand kids a stack of color-coded shape cutouts and let them arrange the cards. The patterns reveal themselves, and the periodic table stops being a wall poster and starts being a tool.

8 Hands-On Stations for Teaching the Periodic Table

A station lab is a student-led activity where small groups rotate through 8 stations (plus a 9th challenge station for early finishers) at their own pace during one to two class periods. You become a facilitator of the content rather than a lecturer. As kids are working, you're walking around, spot-checking, breaking misconceptions, and guiding students through the early phases of mastering the concept.

The Periodic Table & Reactions Station Lab has four input stations (where students take in new info on how the periodic table is organized) and four output stations (where they show what they learned and apply it to chemical reactions). Here's what's at each one.

4 Input Stations: How Students Learn the Periodic Table

🎬 Watch It! —

A short YouTube video walks students through how the periodic table is organized. Students answer three questions about how rows (periods) order elements by atomic number, how columns (groups) order them by chemical properties, and how Mendeleev built the original arrangement. Visual learners come alive at this station.

📖 Read It! —

A one-page reading passage explains the periodic table's structure, with vocabulary work on periods, groups, chemical properties, and reactivity. Three comprehension questions follow. Comes in two reading levels (dependent and modified) so you can differentiate without prepping anything extra. Spanish version included.

🔬 Explore It! —

This is the heart of the lab. Students get a stack of color-coded shape cutouts (different shapes for groups, different colors for periods, with numbers that increase across the rows). They arrange the cards however they think makes sense, then answer questions that nudge them toward discovering the periodic table's actual structure. By the time they're done, they've built a mini periodic table by hand and can locate any element by group and period.

💻 Research It! —

Students use reference cards (or the Genially in the digital version) to identify the elements involved in four sample chemical reactions. They figure out which reactions pair up groups 1 and 17, which pair up groups 2 and 16, and why the periodic table can predict that. This is where TEKS 8.6B's standard ('use the periodic table to identify atoms involved in chemical reactions') gets directly addressed.

4 Output Stations: How Students Show What They Learned

📋 Organize It! —

A card sort. Kids physically arrange element and vocabulary cards under the right categories: periods, groups, chemical properties, reactions. Easy to spot-check at a glance — this is where I'd stand if I wanted to see who actually gets it.

🎨 Illustrate It! —

Students draw a blank periodic table and follow a checklist: number the groups 1-18, number the periods 1-7, color period 4 red, color group 14 blue, mark three elements with similar properties yellow, star oxygen, put a square around magnesium. Even kids who say 'I can't draw' surprise themselves here.

✍️ Write It! —

Three open-ended questions where students explain how the periodic table is arranged, how it can predict reactions, and a common misconception (that elements in the same period have similar properties — they don't, that's groups). This is the writing practice middle schoolers need and rarely get in science class.

📝 Assess It! —

Eight multiple-choice and vocabulary questions that double as a quick formative check. If you're grading the lab, this is the easiest one to grade.

Bonus Challenge It! Station for Early Finishers

🏆 Challenge It! —

Optional extension for early finishers. Requires teacher approval before they start (so it doesn't become a free-for-all).

How This Fits Into a Complete Periodic Table and Chemical Reactions Unit

At Kesler Science, most of our middle school resources are built around the 5E method of instruction (Engage, Explore, Explain, Elaborate, Evaluate). This Station Lab is from the Explore phase of the Periodic Table & Reactions 5E Lesson for TEKS 8.6B.

The full 5E Lesson also includes an Engage hook and activity, PowerPoint slides and interactive notebooks for Explain, student choice projects for Elaborate, and an Evaluate assessment. If you want the whole two-week unit, grab the 5E. If you just need the hands-on day, the Station Lab is plenty.

Materials Needed to Teach the Periodic Table With Shape Cutouts

Materials beyond what's in the download:

Almost nothing. The shape cutouts students use at the Explore It! station are included in the download. You'll just need to print them and (optionally) laminate them so you can reuse them every year.
Pencils and the printed answer sheets (included)
Scissors if you want students to cut their own shapes (or pre-cut them yourself for faster station rotation)
A device with internet for the Watch It! station

Standard covered: Texas TEKS 8.6B —

Grade level: 8th grade chemistry (also works as a stretch lesson for advanced 7th)

Time: One to two class periods (45–110 minutes total). Plan for two periods the first time you run a station lab.

Common Student Misconceptions This Lab Fixes

"Elements in the same row (period) have similar properties."
Wrong. Properties shift dramatically across a period. Sodium (Na) and chlorine (Cl) are both in period 3, but sodium is a soft metal that explodes in water and chlorine is a poisonous gas. It's the columns (groups) where similar properties live. The Write It! station catches this one head-on.
"The periodic table is just a chart to memorize."
It's a predictive tool. Once kids see that group 1 + group 17 elements always react (sodium + chlorine, potassium + chlorine, etc.), they realize the table tells them what's going to happen, not just what something is called. The Research It! station is where this clicks.
"Atomic number is just a label."
Atomic number IS the element. Change the atomic number, change the element. The Explore It! activity has kids arranging shapes by number and then realizing the numbers aren't arbitrary; they're protons, and they define what each shape is.

Tips for Teaching the Periodic Table in Your 8th Grade Classroom

Two things make this lab go smoother the first time:

1. Pre-cut the shape cutouts the day before.

The cutouts come in the download as printable pages, but cutting them takes 5–10 minutes you don't want to lose during station rotation. Cut them yourself or grab a parent volunteer. Laminate them and you'll never have to do it again.

2. Stand near Explore It! during the first rotation.

Watch how kids arrange the shapes. Some will sort by number first, others by color, others by shape. The 'aha' moment happens when they realize all three patterns work together — that's the periodic table revealing itself. If you don't see that moment, slow down before moving to the Explain day.

Frequently Asked Questions

What does TEKS 8.6B cover?

Texas TEKS 8.6B asks 8th grade students to use the periodic table to identify the atoms involved in chemical reactions. Students should be able to read the periodic table's organization (periods, groups, atomic number) and use those patterns to predict what elements will combine and how.

What's the difference between a period and a group on the periodic table?

A period is a horizontal row. Properties shift across a period (a metal on the left, a noble gas on the right). A group is a vertical column. Elements within a group share similar chemical properties, which is why elements in groups 1 and 17 reliably react with each other.

How long does this periodic table activity take?

One to two class periods (45 minutes to 110 minutes total). If your students are familiar with station labs, they may be able to finish it in one class period. However, many teachers like to use the input stations on one day and the output stations on the second day.

Do I need to provide my own materials?

Almost nothing. The color-coded shape cutouts students use at the Explore It! station are included in the download. You'll just need to print them, cut them, and (optionally) laminate them so you can reuse them every year. The Watch It! station also needs a device with internet.

Can I use this for 7th grade or in a 1:1 digital classroom?

Yes to both. The Modified version of every station works as a stretch lesson for advanced 7th graders. The full digital version (PowerPoint or Google Slides) works in 1:1 classrooms and Google Classroom — students type into the slides and submit them back.
