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

## Rocks, Fossils, and the Law of Superposition Sequencing Activity

Objectives:

• Sequence information using items which overlap specific sets
• Relate sequencing to the Law of Superposition
• Show how fossils can be used to give relative dates to rock layers.

Materials:

• Fossils, Rocks, and the Law of Superposition Google Slides – this will walk you through the lesson step-by-step
• additional lesson plan details on their site
• print and cut apart the 8 cards for each part of the lesson
• to set up the cards, use large 4×6 index cards and store in ziptop bags.
• on one side of the index cards, glue on the nonsense letters
• on the reverse side, glue on the fossil layers
• laminate for durability
• Replace the letters for each fossil layer, see my ppt for new random letters
• spelling out the word “ORGANISM is way too easy for students to figure out and they will not really have a chance to work on the activity with the depth of thinking and problem solving that you want them to do
• be sure to stagger cards so that the order of the cards is not the same, otherwise they will flip over the cards and have the answer for part 2
• Notes HandoutLaw of Superposition Notes (pdf) students will take notes and record their answers on this handout.

Tips for this lesson:

This is a fantastic lesson and I have used it successfully with both 5th and 6th grade students. When introducing this lesson I use the analogy of a laundry hamper, or in most cases, the pile of dirty clothes on the floor in their bedroom. Today’s clothes would go on top of the pile, each day adding a layer of dirty clothes. The older clothes would be on the bottom of the pile, kind of like a timeline of what they wore this week. When that laundry is collected and moved to the laundry room, the layers would get disrupted. With rocks, the layers form on top of each other, and the older layers are on the bottom. We then brainstorm how those layers can be disrupted: earthquakes, tectonic plates moving, landslides, digging, etc…

For this activity, they have to figure out the pattern of how these layers are formed, and there are clues in each layer, they just need to know what to look for. For the nonsense letters, there is a pattern that connects all the layers together. Many will think it is alphabetical, but I tell them that it is not. Once they have worked on it a few minutes, I have them share their theories. Once each group has shared their theory, I give them the clue. And suddenly, the pattern is clear now that they know what to look for. Using the same strategy, they will then sequence the fossils on the reverse side of the index cards.

## 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

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

## Genetics with SpongeBob – Learning how to use Punnett Squares

If you have a unit on genetics, this is a must have as part of your lesson plans. The worksheets were created by Tracy and posted on her website, ScienceSpot.net (link). I created a Google Slides presentation for my 7th graders to help them set up, solve, and analyze Punnett squares.

As a class, we worked on the first few problems together. Then, students worked with a partner and self checked their work using the ppt slides. For homework, they were to finish the problems and self check using the ppt slides. In class the next day, we reviewed some of the problems to check for understanding.
