Lab Activity Master List

I was asked if I would post my "master list" of lab activities. These are not necessarily lab activities I have for sale, though you may find a couple in my TpT store. Most of them I found by Googling free resources or by browsing Teachers Pay Teachers. If you search the terms, most of the time, you should get some kind of idea for an activity. Some activities I do with all grade levels (such as "Saving Fred" and microscope skill activities), I just make alterations to make them more challenging for older students. If you have a question about a specific activity, let me know and I'll try to get back with you. (I'm a lot more active on Instagram, so if you have an account, try messaging me there. I'm not a regular blogger.) I'll try to add links to things as I have time and make this a growing list.

General Science

Lab Safety-Kesler escape room on TpT

Microscope Skills-Letter E activity (Google for lots of versions), CSI mystery powder 

STEM-Egg Drop Challenge, Ship a Chip, foil boats, paper bridges, cup challenges, Saving Fred gummy worm activity (Google for lots of versions of each activity)

Writing Lab Procedures-Students build an animal using marshmallows and toothpicks, then write step-by-step directions for their process. Cover original animals (or take photos, if your school is 1:1 with technology) and have groups trade directions to see if they can correctly build each other's animals.

Physical Science

Visible Light-Use red, green, and blue bulbs to experiment with light color mixing; test opacity/reflection/transmission/etc. of various materials (foil, wax paper, plastic wrap, etc.) using a flashlight

Electromagnetic Spectrum-Use spectroscopes to observe different types of lights (LED, incandescent, fluorescent, etc.). If you do not have spectroscopes, I ordered some inexpensive ones from Home Science Tools or you can make them from old CDs and cardboard paper towel tubes (Google how-tos).

Sound Waves-To visibly observe sound waves, hit tuning forks on table and quickly submerge in a bowl of water. To observe how sounds travels more efficiently through solids than gases, tie a string to a metal dinner fork so that there are two long "tails". Hold the ends of the strings against ears and press ears closed. Have partner tap the fork. If your students have iPads, Garageband is a fun app to experiment with.

Properties of Waves-Use slinkies to observe transverse vs. longitudinal waves.

Physical vs. Chemical Changes-Mystery white powder activity; a version of this is available in my TpT store. If you don't like my version (it's pretty sparse), I'm sure there are plenty of others.

Atomic Structure-Make edible diagrams using Skittles for protons/neutrons and Red Hots for electrons. Practice identifying different information on periodic table to create atoms for different elements.

Periodic Table & Metals/Nonmetals/Metalloids-Alien Periodic Table

Elements/Compounds/Molecules-Paperclip models

Acids, Bases, & pH-Identify pH and neutralize common acids and bases with red cabbage indicator. 

Chemical Bonds-Drop on a Penny activity (Google for lots of ideas.)

Balancing Chemical Equations-Use candy or math manipulatives to model.

Balanced/Unbalanced Forces-Experiment with bouncy balls, dominoes, and spring scales (I'll try to remember to post my activity when I find it).

Motion & Acceleration-Calculate speed of toy cars on ramps.

Newton's Laws-I do the simpler of these activities that I have materials for.

Potential/Kinetic Energy-Build marble runs.

Simple Machines-Design Rube Goldberg machines.

Pickle Autopsy: Teaching Anatomical Position Vocabulary

So, anatomical position vocabulary isn't actually in any of the standards I'm supposed to be teaching. But, my 8th graders had their state test April 16, more than a month before we get out of school, and I had to have all 8th grade standards taught and reviewed by then. So, what's a gal to do with 8th graders for the next month of school?

Start teaching high school standards, of course!

Our students have a choice between two different high schools in our district, and they won't all necessarily go straight into the same class in the 9th grade. Some may end up in Biology, while others may end up in an intro or general science class. So I had to decide which skills would serve them all.

I figured Greek & Latin root words and anatomical position vocabulary would be the most useful basic skills for them. We already cover Greek & Latin root words throughout middle school, so I decided they might not be very engaged in what would just seem like end-of-the-year review, so I narrowed my focus to just the anatomy vocabulary.

I made a PowerPoint and guided notes outline to introduce the topic. We practiced labeling a few diagrams, and the unit culminated in an autopsy...a pickle autopsy.

Now, I could have done an actual dissection (frog, etc.) except for these caveats:

• It's the end of the school year, so funds are a little low for ordering a bunch of preserved specimens.
• It's the end of the school year, and last minute orders might not arrive in time.
• I have some dissection tools, but not scalpels, which could be necessary for many specimens.
• I'm not comfortable introducing scalpels to my students at this point.
• I don't want to steal the thunder of a high school biology teacher who is looking forward to doing students' first "real" dissection with them. High school teachers are better equipped than I am. I need to leave it to them.

Hence, pickles. It's the perfect way to review anatomical position vocabulary and introduce dissection skills without dissecting an actual preserved specimen.

Here's the basic setup:

Each team got a dissection tray, plastic knife, tweezers, pick, hand lens (not shown), dropper, Petri dish, and a "victim" (pickle). Each victim had its own "punny" toe tag with identifying information. Some of the victims had the same last name so different student teams could confer to decide if they were related or not.

I made a very basic reference sheet for each table.

One station was a "Toxicology Lab" where students would get a sample of their victim's body fluid (pickle juice) and test it with red cabbage indicator to check pH. Some of the victims had been "poisoned" (soaked in baking soda solution), so they would get an alkaline result. I had a pH scale and a few samples already set up. My 8th graders have learned about pH, but it was in 7th grade, so it had been a while.

I added a little food coloring to the body fluid samples because the "poisoned" samples were a little lighter in color, and I didn't want it to be obvious that there was a difference. (Food coloring shouldn't affect the results much.)

I had a few pre-made samples set out in a chem plate so my students would know what to look for.

Here are my very hilarious toe tags. I don't know if my students "got" it. I didn't see any of them roll their eyes. 🙃 Vinnie Gar is perhaps my favorite.

Here, the students are dissecting. They recorded their observations on a lab sheet.

It wasn't obvious at first, but every victim had a variety of wounds. They had all been cut with a knife and stabbed with toothpicks (I left pieces of them embedded). Some had tiny balls of aluminum foil that I had inserted by poking them into the pickle with a toothpick. A couple of them had a gherkin inside (baby pickles!). A few had even been poisoned (the baking soda solution I mentioned above). Students had to draw and label dorsal and ventral wounds and describe each wound using superior/inferior, proximal/distal, medial/lateral, etc.

This was one of my favorite labs we have ever done. I'm so glad we had a chance to do it.

I'd like to share it with you, as well!

This is based off a file from The Forensic Teacher Magazine. This is the original. I simplified and shortened it a little for my middle schoolers. You can access all of my anatomical position vocabulary and pickle autopsy files here.

Your lab/classroom is going to smell like pickles afterward, but that's a small price to pay for such an engaging activity.

Um...It's been a while

I'm a bad blogger.

Has it really been more than a year since I last blogged?

Anyway, I've been thinking that I'd try to do better and start posting some of the cool things my students do here. It would also be a good way to share activities with everyone that I don't necessarily want to post on Teachers Pay Teachers. Click here for my store. There's not a lot there, but you might find something useful.

I'm a lot more active on Instagram, so during my next hiatus, that's probably where I'll be. My handle is @middleschoolmadscientist.
