Chemistry Unit - Worksheets Chemistry Cards Interactive Notebook Piece and more

I am excited to share our new chemistry unit with you! (It has been recently updated and now is around 150 pages!!) As you know, we love hands-on activities and I want to show you some of the fun ways we explored the periodic table and touched on topics like valence electrons, Bohr Diagrams, Lewis Diagrams (electron dot diagrams), ions, isotopes, and more!

Some of the topics we explored included:

  • 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

Chemistry Unit - Periodic Table Ions Isotopes Bohr Diagrams and moreWe did this unit together when the kids were 10, 12 and 14.  I think this unit is best for middle school and up (perhaps as a supplement to for high schoolers being introduced to chemistry for the first time).

Note: Chemistry for Elementary — My youngest enjoyed the unit, but some of the topics we touched on as the unit went on were a bit above her head. (She still wanted to participate but acknowledged it was challenging for her!)  Be sure to this post Fun, Simple Science Experiments for Younger Kids! (Introducing Kids to Chemistry) if you have younger kids (It has a free Chemistry Experiment Packet for young learners.)

The First 20 Elements and Elements with Unusual Symbols:

Update: There are two new chemistry booklets on the first 20 elements and on elements with unusual symbols in this packet. My youngest was in 5th grade she worked on these pages. 🙂

Chemistry Activities - The first 20 elements - unusual symbols

She used a beautiful book about the elements by Theodore Gray Elements: A Visual Exploration of Every Known Atom in the Universe   (affiliate link) as a reference. It has huge pictures of the elements as well as pictures of items that use this element.

Booklet and the book - Elements A Visual Exploration of Every Known Atom in the Universe

This booklet had her 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.Chemistry Booklet on the first 20 elementsBuilding Molecules Activity

My 5th grader also spent some time building molecules.

Period Table Hands-On Activities

This was the first activity we did as we started looking closely at the Periodic Table:

Hands-On Chemistry Activities - The Periodic TableIn the packet, there is a student instruction sheet on how to color the elements. This activity includes the first 36 elements.  My daughter spent several days coloring the cards (while we did read alouds).  We talked about Mendeleev, who was the first to develop the periodic table and discussed how challenging that must have been.  I told them that Mendeleev knew quite a bit about the properties of the various elements… and with their color-coded cards, they had considerable information too.  They had to build the periodic table.  The teacher notes (pictured below right) explain some of the hints I gave them on the way, but they did a great job with it as you can see from the pictures above! Along the way, the students took notes on the observation page (seen below in the middle) about the families they were looking at. (For example, they pretty quickly figured out that the blue elements were all metals — like iron, copper, zinc, etc.).  They also saw that the yellow cards all had one little electron in the lower left corner.

Note: There are cards for the elements 1 (hydrogen) through 36 (krypton) included in the Chemistry Packet.

Chemistry Unit - Building the Periodic Table ActivityNext we went over the parts of the atom (nucleus, protons, electrons, nucleus, etc.).  We did another hands-on activity to introduce the kids to valence electrons. I handed the kids Bohr Diagram cards that were the same size as the element cards from the activity above.  I divided the cards among the kids and had them place the cards on top of the cards below.

Chemistry Unit - Bohr Diagrams Valence Electron Activity - Parts of the Atom worksheet 2Then, the kids had to observe the kids and see if they could find any trends:

  • each row/period added on “shell” (or ring) around the nucleus
  • each column/group had the same number of electrons in the outer ring (except for helium)

Note: There are Bohr Diagram cards for elements 1 (hydrogen) through 20 (calcium) included in the Chemistry Packet.

Hands-On Chemistry CardsThe next day, the kids did a cut-and-paste activity with those same Bohr Diagrams.  We used this chart a lot as we continued on with this unit because then they could easily see how many valence electrons were in the outer shell of the elements!

They also did the worksheet I made for them which has them look at the number of shells and number of valence electrons various elements have.

Bohr DIagrams - Valence Electrons -Worksheet and ActivityWe went on to talk about some of the information in the Periodic Table such as atomic number, atomic weight, chemical symbols & the element names

Chemistry Unit - Periodic Table Worksheet - atomic number atomic weight chemical symbolWe also talked about some of the groups of the Periodic Table – alkali metals, alkaline Earth metals, halogens and noble gases.  We talked in quite some depth both about the general properties of these groups and also about some of the properties of the elements themselves:

Chemistry Worksheets on the Alkali Metals, Alkaline Earth Metals, Halogens and Noble Gases

We went on to talk about Lewis Diagrams. These are similar to Bohr Diagrams, but only provide information about the valence electrons (the outer electrons of an element). By this time, the kids were able to whip through this worksheet (using the Bohr Diagram cut-and-paste activity above):Lewis Diagram WorksheetWe did a *really* fun activity when we explored Lewis Diagrams! My kids were stunned when I brought out bowls of Fruit Loops (not a regular item on my grocery store list, LOL!!!)

Lewis Diagram Activity - Chemistry Hands-On ActivitiesPeriodic Table – Metal – Nonmetal – Metalloid

Our next topic was about metals, nonmetals and metalloids and how this information can help us understand different types of bonds that are formed. We talked (briefly) about covalent and ionic bonds.  We talked about that in covalent bonds electrons are shared, which in ionic bonds atoms give their atoms away.  It was beyond the scope of this unit to go into much more detail than this, though I did touch on electronegativity charts. We looked at the Pauling Table and talked briefly about how that chart can help scientists determine/understand the types of bonds that are formed. (There is a page about that in the chemistry packet.)

Periodic Table - Metals – Nonmetals – MetalloidsWe did a review activity. The kids created an interactive notebook piece for their science notebooks about the Groups of the Periodic Table. The kids cut out examples of one Bohr Diagram for the groups, plus they cut out descriptions of each group. Your student can use the information provided or write their own description for each group.  There is an answer key provided (but not pictured below!).

Chemistry Interactive Notebook PIece - Groups of the Periodic TableThe chemistry packet has some matching cards for some of the unusual chemical symbols that the kids memorized.  We also touched on some of the trends in the Periodic Table (though we really didn’t go into that much detail… that will come when they do high school chemistry).

Chemistry - Trends in the Periodic Table Worksheets - Unusual Chemical Symbols

Elements with unusual symbols activity

One afternoon, I brought out some ping-pong balls and cups. The kids thought that was funny and enjoyed trying to bounce the ball into the correct cup! 🙂  Below you can also see some of the chemistry review cards I made for the kids (with many of the terms they learned during this unit… from proton and neutron to halogen, covalent bond, and anion and atomic number.

Chemistry Unit Review

You might end your chemistry unit there or you can go on to talk about electron configuration.

With my older two (and now with my youngest, age 13), we talked about electron configuration & electron notation.  (For example, oxygen is 1s2, 2s2, 2p4 — does that ring a bell from you high school chemistry days?!)

My kids thought it was tricky at first, but then quickly got the hang of it.

I have just updated this section to add in a number of colorful sheets (that go along with the s-block, p-block, d-block and f-block colors on the reference pages):

Electron Configuration Worksheets - Chemistry UnitI included some pretty in-depth teachers notes. Of course, you can always email me if you have any questions!

Here are a few close-ups of this material:

Electron Configuration Activities - WorksheetsElectron Configuration Worksheets for the Transition MetalsThis packet includes a general teach plan & information about how we completed this unit.  Our family took about 4 weeks (though there were some weeks when we only did science 4 days or only spent a brief amount of time on science that day.)

Do I need any specific books with this unit?

No, our notebook pages and worksheets include answer pages and teacher notes.  There are several chemistry resources I’m glad I had on hand, though. These are affiliate links:

Chemistry Resource BooksUnderstand Basic Chemistry Concepts – I originally got the free version on my Kindle, but I liked it so much I felt I had to have the book itself!  Chapters 1 and 2 are especially useful with this unit.

Chemistry Homework Helpers by Greg Curran – This is fairly advanced (and I didn’t use it with the kids), but was really useful for me as the instructor.

Glencoe Chemistry Matter and Change – I purchased quite a number of used high school chemistry textbooks (8!! Crazy right?!!) and after going through these, the one textbook we wound up using a lot (for my high schoolers) was this textbook. It has all the answers to the practice problems in the back (not just the odd answers!).  We used this A LOT when my kids covered high school chemistry, but I was glad I purchased it when my kids were in middle school so I could use it as a reference.

One Mom asked if this packet is suitable for someone with little to no chemistry knowledge.

Here was my answer! Yes! I provided all of the answers and actually added in quite a number of teaching hints along the way. I designed the activities so that the kids discover some of the patterns of the Periodic Table themselves. (That’s why Bohr Diagrams are really useful, if a little outdated in our knowledge of atoms!)

In this packet, I have a general guide at the beginning of the packet of what we did on day 1, day 2, etc. b/c I thought some parents might want a bit more guidance. I tried to make it pretty straight-forward (so even wrote out instructions for what I said to the kids on certain days and what hints I gave to help them discover the answers/patterns for themselves.
