Think Like Scientists: Can You Balance An Egg on Its End?

“Great discoveries and improvements invariably involve the cooperation of many minds. I may be given credit for having blazed the trail, but when I look at the subsequent developments I feel the credit is due to others rather than to myself.” Alexander Graham Bell

There is an urban myth that the only day you can balance an egg on its end is during the spring equinox, which happened to be March 20th at 12:57 pm. Is that true and how can we know?   Here’s how:
Use the CL-EV-R model to engage your students in an activity where they try to balance a egg on its end.   CL-EV-R stands for Claims, Evidence, and Reasons and is a wonderful teaching and learning strategy to support argumentation in the Common Core as well as learning in science.
The short version of CL-EV-R is for students to make a Claim, gather EVidence to support the claim, and explain their Reasoning for why the evidence supports or does not support the claim.


Below is a 5E Lesson Plan: Can You Balance An Egg on Its End?
For this activity, I suggest using a dozen eggs, one egg per group of 2-3 students. Explain to the students that you have heard that it is possible to balance an egg on its end only on certain days such as the Spring Equinox. Ask them to pair-share what they think about that statement (or claim). Ask them to talk about evidence they can gather to prove or disprove the claim. The response you are looking for is “let’s just try it today!”
Hand out one egg per team of students, or even one egg per student. Have paper towels handy for that one egg that will roll off the table or desk and needs to be cleaned up!  Use the opportunity to talk about the effects of gravity! Allow students to try to balance their eggs.   Note – for every dozen eggs, about 25% will balance! Be prepared for the “ah-ah!” experiences students will have when several of them do balance their eggs! Record student results in a t-chart.  You may want to ask students to predict how many eggs out of a dozen will balance and how many will not.
Look at the class data.  How many eggs were students able to balance?  How does that compare to the student predictions? Why do some eggs balance and others do not?   (There is a reason that you can read about on-line). What does the evidence tell us about the claim that you can only balance eggs on the Spring Equinox?
Does it make a difference if the eggs are raw or hard-cooked?
Would we get similar results for duck, quail, or other types of eggs?  How about an ostrich egg?
Is it possible to balance an egg on its pointy end?  (I have been able to do that only once in the last 1472 eggs I have tested!)
If you freeze the egg would it be easier or harder to balance?
Challenge students to do the same activity with their parents, brothers, sisters, aunts, uncles, etc!  Take a picture and share! Include this activity as part of your school’s STEM Night of Science and Math Night. Gather other questions from the students.
Take a picture of your students doing this activity and share on your school’s website.
In this lesson students are using all the 21st century skills. To integrate technology seamlessly into the lesson, you can have the students blog about the experience, create a presentation demonstrating their results such as using EduGlogster or creating a poll (poll everywhere or Google Forms) to gather the results from the class.

Using ThingLink in the Classroom

“An essential aspect of creativity is not being afraid to fail.” by Edwin Land


Thinglink was introduced to me when I was at the NC Technology in Education Society (NCTIES) Conference during a presentation by Richard Byrne (@rmbryne). I thought it was a really great FREE web tool but was disappointed it didn’t also have an app. A few weeks ago, Thinglink launched their FREE app, which I love!

What is Thinglink? Thinglink makes pictures interactive with text, video, images and links. When you click on a Thinglink image, you’ll see symbols such as red video circles and dots where it is interactive. Thinglink has endless possibilities in education. My top 3 ways of using it in education are below:

1. Student Portfolios: Teachers can use a picture of a student and through-out the year, students can add images of their work or video to show mastery of content. By doing this each quarter the teachers, students and parents can see the progress over the year. Each corner of the picture could represent each quarter/semester.

2. Assessment, Projects and Presentation: Students can create Thinglinks to show their understanding for any Common Core or Essential Standard. Teachers can have a rubric setting the expectation for what they want in the Thinglink. For example you could require, two text boxes, a link and  a video. Or you can set the expectation that the student must show mastery of a standard, and the student has a little more freedom to determine what that looks like. Having the students creating Thinglinks lets them use all their 21st century skills of critical thinking, creating, communicating and collaborating (if they work with a partner).

Ex of Assessment: The student can draw out any topic, for example the water cycle or a math problem, using the free Skitch app. The student can save it to their camera roll and then create a Thinglink demonstrating their knowledge by adding recordings, text and links explaining their thinking.

Ex of a project: The students can make book reports by taking a picture of the book cover and embedding a movie trailer that they have created for the book. Or for non-fiction the student could find a picture of the person like Steve Jobs, and they can show their understanding of the book. Click here for my example, I chose to do a favorite quote and speech.

A fabulous teacher, Lisa Maples, embedded her class Thinglink into her wiki, as an end of year project. There are  links to various digital projects that the students have created.

3. Lesson Plans and Homework: Teachers can create Thinglinks to help differentiate lessons and homework. Using any image, the teacher can add the content they want the students to know. You can even spice up graphic organizers and info-graphics.

Ex of  a Lesson Plan: The teacher can take a picture of an ecosystem and add all the vocabulary words and/or videos that can help the students learn the topic.

Ex of Homework: This is a great way to flip the classroom. You can embed videos and practice problems on a  topic and have the students complete for homework. Click here for an example using comparing fractions.

Thinglinks are easy to create on both the website and in the app. First create an account at (it is free). If you want to create a Thinglink on the app, download it, and then sign in. Using the pictures in your camera roll, chose one and then tap anywhere on the picture. Here you add the content you want such as video or text, add a title and you are done. You can share it by emailing the link from the app but it also automatically syncs; when you log into your account through the website, you can share it many more ways. If you are creating a Thinglink on the website, click on create in the top right corner and chose an image that is on your computer or for a website (make sure it is a creative commons imagine) and add your content. That is it, I love free and simple!

Any of these Thinglinks can be made into a QR code as well. You can have these posted around the room as helping aids or to inform the students. Just copy the url and paste into any QR code creator such as qrstuff or follow my directions on my blog post about making  QR code in google drive.

I would love to hear how you have used Thinglink or want to use it in your classroom, please share in the comments or on this open Thinglink I created by clicking edit and adding your idea. (To make a Thinglink where anyone can add info, click on the edit tab and set your settings to anyone.) Another great way to have students collaborate in the classroom.
