Unpacking Big Discoveries for Little Learners


There have been so many exciting scientific discoveries and breakthroughs in the past few years. Most recently, all the buzz is around the confirmation of gravitational waves, theorized by Einstein a century ago. The question for me as an educator is always how to share these important advances in science with students.

How does one explain a concept like gravitational waves to the very young? Particularly if you have to read several articles on it yourself to feel like you've grasped it?! Good news: you don't. No, I'm not saying that young children are not capable of learning difficult concepts, nor am I saying that science is not an important part of early childhood and elementary education. However, I am saying that what is more important when teaching kids in the years before middle school is laying a strong foundation in the sciences so that they can grasp all of these cool scientific advances when they read about them in their future textbooks.

(That said, if you live with, or teach a budding astrophysicist, there is no need to stifle their passion by not exploring these more complex concepts.)

When I was a science specialist for Preschool through 6th grade, I was often met with the incredulous response of "You teach 3 and 4 year olds science?!?" as if the idea of it was crazy. Yes, I do, and it's a lot of play and discovery. I think many people hear science and can only think of lab coats and Bunsen burners. When you teach at this level you are building the foundation that students will pull from in the more advanced years of their education. Science at this age has so much to do with forming kids' understanding of the world around them. 

So let's unpack the discovery of gravitational waves for the little guys. What basic science concepts are inherent in this topic? How can we build on understanding as they continue their education?

Early Childhood

Gravity: Young children do not feel the need to wait until science time to experiment, they are constantly experimenting. They've learned about gravity through learning to walk, building towers and knocking them down, building more towers and knocking them down...they might not have the vocabulary term for it, but they are already beginning to understand the concept of gravity. There is no reason not to introduce the vocabulary to go with their exploration.

Try some fun age-appropriate activities for exploring gravity:
Use fiction books such as Sheep in a Jeep by Nancy Shaw and non-fiction stories like I Fall Down by Vicki Cobb to explore the concept further.

     

Space: Explore the objects of space, starting at this age with the planets and the sun. Developmentally the idea of scale is a difficult one at this age. However, you can begin to show that some planets and space objects are larger than others, laying the groundwork for when scale is more comprehensible.

Waves: Students may have experienced waves at the ocean, or in the bathtub. Introduce the idea that there are other types of waves, some that we can't see. At this age, use sound as an example. Although we may not be able to see sound waves as they move from an object to our ear, we can see vibrations.

One of my favorite fun and messy ways to "see" sound is to tap a tuning fork and then dip it in a basin of water. It will make fun splashes and ripples.

Check out these other ways of seeing and feeling sound on my Pinterest board, "Sound Science"
 

Elementary

Gravity: Elementary students are better suited to begin to understand the concept of gravity beyond objects falling down. Try these gravity activities with elementary students.
Some elementary book suggestions for exploring gravity are Gravity by Jason Chin and Gravity is a Mystery by Franklyn M. Branley.

 
Space: This is the perfect age to begin building those to-scale solar system models on the playground. Students are better able to understand scale at this age (although it is still far from an easy concept!). They also love to learn about new things, so adding other space objects like asteroids, dwarf planets, etc. can be fun. You'll find seemingly infinite resources from NASA on their website.

Waves: You can now add light to your study of waves, in addition to sound (although those activities are still fun and useful here!) Try this activity, Big Wave, from the Center of Science and Industry to explore waves.

A great early elementary book for studying the properties of light waves and reflection is I See Myself by Vicki Cobb.


Einstein: Elementary is a great time for biographies. Inspire students with how Einstein's ideas and theories have held on and discoveries are still being made 100 years later. Try On a Beam of Light: A Story of Einstein by Jennifer Berne, and I Am Albert Einstein: Ordinary People Change the World by Brad Meltzer.

 

Middle School, High School and beyond

Gravitational Waves: At this point, students are poised to learn and understand current events like the confirmation of gravitational waves because of the strong background they've developed if they have been learning concepts like those we've outlined here.

Some excellent starting points to understand this idea:
As well as this video brought to my attention by the author of the blog iGameMom 



Super Novas and Black Holes: Along with concepts like the Big Bang, pulsars and binary stars, super novas and black holes are not only interesting to study, but are applicable to the study of gravitational waves. Try these hands-on activities to further explore these concepts.
Einstein: Some books for early middle school: Who Was Albert Einstein by Jess Brallier and Albert Einstein and Relativity for Kids: His Life and Ideas with 21 Activities and Thought Experiments by Jerome Pohlen.

ABC's of Earth Science


A is for Asteroid?! It is in the ABCs of Earth Science, part of the Jumbo Minds' Science ABCs book series. In this book, illustrated with bright, bold colors, each letter of the alphabet is paired with an Earth Science vocabulary word and definition.

ABCs of Earth Science

This book series, that also includes the ABCs of Biology, Chemistry and Physics is based on the idea that children's capacity to learn new concepts and vocabulary at a young age is so great. Why not incorporate science into their study of the alphabet? A isn't just for Apple after all!

As an early childhood science teacher for many years, I found that young children are indeed capable of learning the words used in science when they are paired with age appropriate activities. You don't have to be teaching rocket science to help build a strong foundation for the later years in science. Using vocabulary like "hypothesis" and "observation" from the get-go allows students to accurately convey the process of science in experimentation through play or classroom science activities. Teaching the alphabet through science fits perfectly into my early childhood teaching philosophy.



The ABCs of Earth Science would be a great book to use along with any early childhood science or alphabet curriculum. Introduce cloud types while reporting the weather during morning calendar activities, N is for Nimbus! Teach the difference between rocks and minerals when you set out the rock collection in the science center, M is for Mineral and R is for Rock.

Although designed for a young audience, the definitions in the book accompanying each letter of the alphabet are not watered down. This makes the ABCs of Earth Science useful in the elementary classroom as well. In addition to the kid-friendly illustrations, the text is designed for all learners using a dyslexic-friendly font to increase readability.

This is certainly a series I will recommend to my colleagues who teach in the early childhood classroom, and for families with young children.

A copy of ABCs of Earth Science was provided by the publisher for review, however the author was not compensated in any other way for this review. All opinions in this post are those of the author.

Celebrate Darwin Day!

charles darwin birthday
February 12th is Charles Darwin's birthday, now known as "Darwin Day". This is a great opportunity to thank Darwin for his contributions to science and learn through some great adaptation and natural selection activities. Who knows, you might even want to throw a Darwin Day party!

This post contains affiliate links, please see disclosures for more information. 

Charles Darwin is known for summing up evidence for the theory of evolution and developing the theory of natural selection through his travels on the HMS Beagle. His book, On the Origin of Species, shaped modern biology and evolutionary theory. Some of Darwin's most interesting work, and what I believe to be the best introduction point for children, was on the diversity of species, particularly the adaptations of island finches.

Darwin observed the finches on the Galapagos islands and found that their beaks varied due to the different types of food and environments on each island. Variation is not only seen in bird beaks around the world, but across bird species. A wonderful hands-on way to engage students in the idea of adaptation is to have them model how these various bird beaks work.

There are many activities where this is explored. In general, the idea is that you provide your class with various items that will serve as "beaks", straws, nutcracker, ladle, chopsticks, etc. The students try to forage for food items with these different beaks. You may provide things like gummy worms in soil, goldfish in water, sunflower seeds to crack, etc. You can get creative with this, keeping in mind you want to model something fairly realistic to nature. Many of the items you use can easily be found around the house.

The following lesson plans outline similar activities:
