3D Printed Science Kits
Ionic Bonding Puzzle Kit
Ionic bonding puzzle to help students practice finding the ratios between atoms based on their charge. Each kit comes with 18 ion tiles (3 of each) and custom tray/lid to organize and store the materials. See the videos below for a demonstration of how the pieces fit together
The color scheme for each style will match the rainbow colors shown photos.
An activity using these kits can be found for free here:
If you have specific color requests, send me a message and we might be able to figure something out :)
Topography Mystery Boxes - Set of 4
Students use a toothpick marked every 1 cm to map out the mystery landforms. From this mapping, they create a simple topographic map and match their mystery maps with virtual landforms.
This set includes 4 different landforms labeled 1-4 and printed in the colors shown as well as black covers with a 5x5 grid of holes. The two halves are held together using 4mmx2mm magnets but could be glued with superglue if you want to make the mystery more permanent. ;)
Each set will also include 6 marked toothpicks and a jig to mark more if needed.
Radioactive Dice and Box
Tangram Square Challenge
In this challenge, a student or group is provided with all of the pieces of this puzzle except for the small square and they are asked to assemble the pieces into a square. After they are successful, it is announced that a new scientific discovery has been made and that the students must somehow incorporate this new information to their puzzle.
There are lots of pdfs to print and cut this design out on paper but sometimes it's nice to have a more durable and tactile model to use year after year :)
Some examples of this activity online:

The large square is 10 cm x 10 cm and all pieces are printed 5 mm thick.
Double Slit - Physical Model
A physical model to show the pattern made by two coherent waves as they “interact” in the double slit experiment
Colors may vary depending on available filament but will be designed to best show the interactions
Resonator
Modeled off of the Exploritorium's resonator demonstration (https://www.exploratorium.edu/snacks/resonator), this single part print shows the resonant frequent of different length oscillators. When you shake the apparatus at just the right frequencies to match the natural frequency of the different lengths, you can drive them independently to a large amplitude oscillation.
The longer the length, the more slowly it tends to vibrate, and the lower its natural frequency. Thus, the long side will resonate at lower frequencies than the short side.
Tangential Velocity Launcher
A Tangential Velocity Launcher for demonstrating that an object moves tangent to the curve once it leaves its circular path
A marble or bearing can be spun up with the lever in the down position and then released by opening the lever gate. Provided with the instructions to “score a goal”, students tend to “discover” the idea of tangential velocity on their own :)
Penny Circles
These labeled circles are a physical version of this quadratic modeling activity where students graph the number of pennies (or nickels) that fit flat in a circle with the diameter of the corresponding circle.
I have found that it's best to have a complete set of rings for each group but groups can also share if you don't have enough for that.
Button Battery LED Holder
A simple little set up to hold a battery and LEDs to make light up necklaces or other crafts involving button batteries.
The 3-Volt 2032 button battery securely snaps into place and built in grooves guide the LED leads into place and hold them snug against the battery.
When assembling, remember that LEDs only work one direction and the long wire must be connected to the positive side of the battery. The LEDs are spaced out so that the battery holder can be taped to the back of a piece of card stock and designed as eyes for a ghost or other character.
To remove the battery, just use the edge of a table to push on the battery through the semicircular cutout on the holder.
Cup Balance
A simple design that uses standard 3.5 ounce plastic cups and a toothpick to measure relative masses.
The toothpick must be round and is a fairly snug fit in the hole on the top but can be easily replaced if it breaks. The supports can be anything that provides clearance for the cups without interfering. As shown in the photo, I just use upside-down large plastic cups
This can used as part of a lab where students use beans as units to quantify a variety of properties including mass.
These sets for purchase include cups and toothpicks in addition to the 3D printed part
+4 Cation Expansion for Ionic Bonding Puzzle Kit
A silver +4 cation piece to add to the Ionic Bonding Puzzle Kit. This piece connects in the same way as the others. These are sold individually so you can determine how many you want to add to your collection :)
BeeSpi V Mount for Marble Ramp
Two 3D brackets to mount a BeeSpi v probe to a 2020 aluminum extrusion. Parts will be printed in black PLA. Mounting hardware not included but details and links to purchase can be found at the following link.
