BubbleSci

Recommended materials:

different types of soap (dish soap, hand soap, bubble bath, etc.), glycerin or corn syrup, items to make bubble wands (pipe cleaners, straws, etc.), measuring tools (cups, spoons, droppers, etc.), stopwatch (or smartphone app), distilled water, containers like cups or empty bubble solution bottles for students to test and keep their solutions.

Description:

Blowing bubbles may seem like a simple or childish pastime. However, blowing a bubble is packed with STEM concepts from physics to geometry to art (with that STEM becomes STEAM!). The lessons provided above allow teachers to take this activity in many directions to suit their instructional needs. For an engineering route, set up design challenges for the bubble wand and the solution. For a math route, study shapes, ratios or volume calculations. For a physics or chemistry route, experiment with air speed, solutions, surface tension and more.

Tips:

If glycerin is difficult to find, corn syrup can be used instead.  Also, your local dollar store may carry small bubble containers with wands as party or wedding favors, which make great containers to store students' final solutions.

Parts Per Million Activity

Required materials:

eyedropper, water, graduated cylinder (10 mL graduations), clear plastic cups, markers, food coloring

Description:

“Parts per million” is a scientific unit of measurement that counts the number of units of one substance per one million units of another. But because it’s hard to conceptualize really large numbers, it can be difficult to wrap our brains around what “one part per million” really means. Kim Preshoff (with help from 100+ animators from the TED-Ed Community) shares nine helpful ways to visualize it. Take this concept further with your choice (or both!) of the two lessons above.

Tips:

The Rutgers Engineering Planet lesson plan calls for masking tape, but the cup itself can be labeled with a permanent marker. For the Country Club Ichthycide Lab, egg platters can substitute the Chemplates. The more affordable option is to use cups, so it is up to the teacher's discretion whether to use cups or the platters/Chemplates. Also, the eyedropper can be substituted by an empty food coloring bottle.

Required materials:

Lesson 1: scissors, pencil, crayon, eraser, pencil sharpener, index card, chalk, calculator, a doorknob (within classroom), roll of tape

Lesson 2: clear cups, antacid tablets, water

Description:

Lesson 1 focuses on how to measure at the nano scale and provides students with an understanding of how small a nanometer really is. Students learn about electron microscopes, participate in hands-on activities to measure common classroom objects in the metric scale, and then convert the result to nanometers.

Lesson 2 focuses on how materials behave differently as their surface area increases. Students will learn about nanotechnology and how engineers can harness the differences in how materials behave when small to solutions for challenges in many industries. 

Tips:

Many craft, household or classroom items that you already have will work for this activity and can be reused multiple times. One class can use one of each item if students can exchange or trade them between groups as they work through their data collection from measuring the length (or diameter for the tape).

Description:

Design challenges provide opportunities to apply skills and knowledge in unique and creative ways. Designers are often asked to create or innovate products that solve complex problems, yet address aesthetic requirements to make the product as profitable as possible.  As you will discover with this challenge, designers sometimes have to embody the role of engineers and artists to ensure all solutions also are aesthetically pleasing and creative enough to serve multiple purposes.

Tips*:

No materials are needed for this project except the teacher's choice of CAD software and one compatible computer per 1-2 students. Basic craft materials can be used to prototype students' physical designs or elevate the activity by 3D printing the prototypes.

Required materials:

household or classroom items, i.e. plastic snack bags, sticky notes, toothpaste, pair of scissors, markers, pencils, etc. within a paper lunch bag

Description:

Many students believe that technology only refers to things powered by electricity. In this lesson, each group of students gets a “mystery bag” containing an example of technology. When students open their bags, they may be surprised to see that they contain everyday objects like sponges, slippers, or bubblegum! (eie.org)

Tips:

Nothing necessarily needs to be bought for this lesson except possibly the paper bags. Many household or classroom items that you already have will work for this activity and can be reused multiple times. Items listed here have already been tested with students as a part of this lesson. My favorite items to use come from the kitchen: Cyclone by Quirky, a spork, gloves, recipe cards, etc.
