Set up hints – students prep items at their table then come up to the tank. After dunking, dry off with towels (I just drop it onto a thick folded up towel next to the tank). I have a bank of TBBs set up on the side of the classroom – students find the mass on their assigned TBBs then record results. Repeat trials. Towards the end of class, students enter all their data into the spreadsheet then I give them the volume of their film canister. Depending on the type of film canister, the volumes are about 39-41 mL. Confirm with a large graduated cylinder or water displacement tank.
This introductory lab is a fun way to analyze data and the students look forward to finding the results each year. Who will be taller, boys or girls? Will we be taller than last year’s class? You can really analyze the data in multiple ways, you can also add the concept of min, max, mode, and range in addition the mean, you can look for trends, and you can talk about sample size, etc…
This post highlights the eight Scientific and Engineering Practices and spotlights a few lessons related to each practice. I had this as eight separate posts but decided to consolidate for easier viewing.
For more details and examples about the Science and Engineering Practices, visit NSTA.

Google Slides 2016 (Public) – this presentation will outline what mining is, where it occurs, types of mines, what commodities are mined in the United States, and covers mining in New Jersey. Maps are from the CDC
What is mining? (pdf) – this is a guided handout that students will take notes on as we discuss mining
Sterling Hill Mining Museum – this has been an annual field trip for our school for around 30 years. Their mineral collection is amazing!
Videos: These are also available on Netflix – updated April 2018
This is one of my favorite activities from our minerals and mining unit. It takes about 1 whole class period to explain the activity, collect data, eat the cookie (& crumbs), and clean up. We discuss our results the next class and determine who made the most profit.
When determining the value of the chocolate ore, I have the students place their chocolate pieces close together in one area of the map. When they are done, I go around and circle the area of chocolate and give their chocolate a rating. They count the number of boxes their chocolate covers and enter it into their spreadsheet.
If there are crumbs attached to the chocolate, I call that ‘slag’ and it lowers the value of the chocolate ore. This leads to a great discussion afterwards when we compare the profits and talk about land use. Is it better to get out as much chocolate as you can, even if you get a lot of slag, or is it better to remove just the chocolate even though you will have less in the end? How is this similar to coal mining? Diamond mining?
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.
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!
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)
to edit this spreadsheet, make a copy for each map, then share editing rights with each group of students who will be working on that map
if you don’t use Google Drive, you can download the Google Sheet as an Excel spreadsheet
ex: Map A data is shared with 4 students from period 1, 4 students from period 2, 4 students from period 3, 4 students from period 4, and 4 students from period 5. When done, they will have 200EQs plotted and color coded on the table top map.
Colored pencils or markers per map
1 Table sized map per lab group (3-6 students) – printed and assembled
The map will remain on the table, as the next class comes in, they will add the data for their assigned region(s) to the same map as the class before them
