This is a great explanation as well – he has tons of Chemistry videos which are geared more towards High School and College Students.

The Atoms Family

Materials:

  • Google Slide Presentation (Public) – a fun way to introduce the parts of the atom and how to determine the numbers of protons, neutrons, and electrons. Get ready to do some singing and snapping 🙂
  • Handoutsvia ScienceSpot.net

Color Coding Families on the Periodic Table

This is a fun way to introduce the families of the periodic table and their properties. The students really enjoy watching the video clips from Periodic Table Videos and the experiments performed by the Chemistry Department at the University of Nottingham.

As a class, we found the location of each family, recorded the elements for each family, discussed their properties, color coded the periodic table, and discussed any patterns they noticed.

Materials

  • Google Slides (Public) – updated for 2016 with links to the YouTube videos to view an element in each family
  • Handout – (pdf) students take notes for each family and use this is a reference for further lessons
  • Periodic Table – (Updated 2016 pdf) I like to use this student version of the periodic table from Jefferson Lab for my 6th graders. I photocopy it double sided – one side stays blank while the other side is color coded. If students have binders with a clear pocket on the outside front, I ask that they place it there for quick reference and access.

This activity was featured on the following blog post: The Joy of Chemistry – A Unit in Photos a few years ago. You can read about how she used this lesson in her 3rd grade classroom as part of her Chemistry unit.

Below is a video about Sodium from Periodic Table Videos. They have a lot of great chemistry videos posted for free on their site, be sure to check them out!

Patterns of the Periodic Table: Finding Shells and Valence Electrons

Materials:

  • Google Slides – students will learn how to find the number of energy levels (shells) for elements in periods 1 – 8 and the number of valence electrons in their outer shells using the periodic table. Updated (Public link)
  • Handout – updated Shells & Valence Electrons
    • Older version: How to determine the number of valence electrons and shells using the element’s group number and period – Notes (pdf) and Slides (ppt)
  • Find that Element!” Worksheet (pdf)- Practice finding the period & group for each element

 

How to draw Lewis Structures – a step by step tutorial

Materials:

  • Updated Google Slides (Public Link) with step-by-step instructions on how to draw Lewis Structures
  • Lewis Diagrams worksheets

How to draw Bohr Diagrams – a step by step tutorial

I updated the Google Slides and worksheet for my lesson on drawing Bohr Diagrams. This lesson will walk your students through the basics on how to draw a Bohr Diagram for the first 20 elements on the periodic table. I also created a simple worksheet for students to record their drawings and do independent practice.

Element, Compound, or Mixture? Identify & Sort

Screen Shot 2016-07-01 at 12.05.24 PM
Students can practice identifying elements, compounds, and mixtures

Materials:

Different ways to use this activity:

  1. Vocabulary reinforcement
  2. Students can review the slides independently as added practice and self check.
  3. This can be a guided mini-lesson for a whole class to reinforce the concept.
  4. Students can work in pairs to sort the cards into the 3 different groups, then discuss the answers as a class. Challenge – categorize the mixtures.
  5. Give each student one of the larger cards and have them do the activity “Quiz, Quiz, Trade

Identifying and Balancing Chemical Reactions

Types of Chemical Reactions (Public)

Tracy has a nice lesson plan and handout on identifying chemical reactions posted on her website: http://sciencespot.net/Pages/classchem.html#chemreactions .  I modified the ppt slides she had posted for her 8th graders to use with my 6th graders as a guided lesson.

I used this lesson after we had already learned how to balance chemical equations using the hands on lesson I created and described below (also found on my Chemistry page):

Balancing Chemical Equations Activity – one of my long time favorite activities. Students will learn how to read formulas, count atoms, create and read chemical equations, and balance chemical equations using a hands on activity with color coded formulas:

We worked through the problems together and I called on students to first identify the chemical reaction and then balance the equation. After a few slides, they began to recognize the types of reactions quickly and had a good understanding of how to identify and balance the equations.

Ionic & Covlalent Bonding Activity

Ionic and Covalent Bonding (Public)

I recently used Tracy’s Bonding Basics 2010 Activity (link) with my 6th graders as a guided lesson. We spent one day on Ionic Bonds, and the second day on Covalent Bonds. Students worked in pairs and practiced making Lewis Structures, finding Oxidation numbers, identifying elements as either Metals or Non-Metals, and determining what each element would do when bonding with another element.

Instead of candy, I used pennies as electrons along with the element cut outs she provides on her website. This was a great hands-on activity to have students ‘see’ how the atoms bond together, and after a few slides, they were able to quickly determine how each element would bond.

Resources:

  • Ionic & Covalent Bonding: Google Slides (Public link)
  • Handout – I modified the handout for use with  my students (link)

Bond with a Classmate Activity

My 6th graders recently completed “Bond with a Classmate” from Tracy’s ScienceSpot website. I have used this activity successfully with both 5th and 6th grade science classes over the years. Here is the description form her website:

Bond with a Classmate (Gail Sanders, Monroe Middle School, Wheaton, IL)

In this activity from Gail Sanders, a member of the MidLevel Science Teachers group in Northern Illinois, students are given a tag (or necklace) to wear with the symbol of an ion and its oxidation number. Positive ions are green and the negative ions are blue. The students are instructed to “bond” with other ions and keep a record of their bonds. Students had to work with their bonding partner to agree on and write a formula and name for the compound they formed. Once that was done, they could break the bond and find a different ion with which to bond. After 5 bonds, students switch tags with another student and start bonding again.

Lesson Worksheets: Bond with a Classmate Cards (pdf) and Bond with a Classmate worksheet (pdf)

I have a modified  version of the student handout posted here (link pdf file). If you have a smaller group of students, I would suggest changing cards after 3 bonds. When a student has successfully made 3 bonds, they come up to my desk, I quickly check their bonds for correctness, and then give them an oppositely charged ion. For example, if a student is Mg +2, they would then receive Cl -1 and make 3 bonds with that new ion.

The version in the video posted above is a more challenging version of the activity, I would suggest 8th grade or higher. Bond with James – free lesson plan on TPT (link). You can also combine both set of cards.

I don’t use the yarn for this activity, the students carry the cards around with them and it is easier for them to place the cards on the table when they pair up so they can write down the formula and compound name more easily instead of looking down and upside down at their cards.

If you have used this activity, would love to hear how it worked with your students and if you have any other ideas to add to this lesson.
