STEM Tuesday — Digging Up History/Archeology– In The Classroom

I love both science and history, so I was really excited to read books on this month’s list. I confess to being a bit grossed out by some of the mummies, but these books didn’t disappoint. I saw many different aspects of the field of archaeology and learned a lot about the societies and people the archaeologists studied.

Mummies Exposed! by Kerrie Logan Hollihan

This book covers many different types of mummies. While many were purposeful, some were accidental. Through the examples, we learn about the science behind the creation of mummies. Analysis of the Items buried with the mummies gave clues to the type of people they had been and how they spent their time when they were alive.

 

 

 

The Whydah by Martin W. Sandler

The search for the pirate ship Whydah required the study of historical maps and records. These records, along with the artifacts discovered on the shipwreck paint a very different picture of pirates than we’ve come to expect.

 

 

 

Forgotten Bones by Lois Miner Huey

This book looks at what archaeologists have learned about a segment of society whose history has gone largely unwritten. I was fascinated by how much information they were able to glean from the bodies. Customs that left permanent marks on the body helped identify those who grew up in Africa versus those that grew up in America. Scars from injuries helped indicate what types of jobs the people performed. Most amazing was the ability of an artist to create a possible representation of each of the skeletons found using DNA analysis and the structure of the skulls.

 

Suggested Activities

In true “me” fashion, my brain went into overdrive thinking of activities that would fit well with these books. Here are a few…

Become an Artifact Detective

Archaeologists have to be detectives. They need to use the clues they’ve unearthed to figure out who these people were, how they lived, and what caused them to die. Challenge your class to be detectives, too.

First, have each person represent themselves with things. Have them pick 5 to 10 items that are often found with them. They could be things they carry around with them or wear every day. They could be favorite items or games we might find in their room at home.

To include science in this exercise, have the students describe the items as a scientist would. What is the item made of? What color is it? What are its measurements? Include a sketch or photo of the item. You could even pretend that these things have been buried for centuries. What would degrade and what would stay whole? If it broke into pieces, what would a defining feature be that might give a clue to what the item is?

For the next part, make sure each list doesn’t identify who the items belong to. Instead, use a student number or a nickname like the archaeologists did in the books.

Provide the set of lists to the class. This could be done by posting them around the room or through a virtual message board. Challenge the students to identify which of their classmates belongs with each of the artifact lists.

Once everyone has attempted to identify their classmates based on their artifacts, have each person present their artifacts and explain why they picked the items they did. The students will not only practice deductive reasoning, they’ll also get to know each other better.

Do Some Research

The discoveries described in The Whydah and Forgotten Bones relied upon historical research to help identify what was discovered. In the case of The Whydah, historical records like maps and diaries helped provide the location where excavators should look for the lost ship.

Use these examples to look into where historical records can be found and what kinds of information different documents can provide. This could even include a field trip to a local historical library or National Archives location and a lesson on how to use microfiche.

So many people use these resources – authors, archaeologists, genealogists, historians, lawyers, and more. To make this exercise more relatable, perhaps tie it to research into a local historical figure or genealogical research.

Debate the Issue

In Mummies Exposed! and Forgotten Bones, archaeologists faced cultures that believed burial grounds should remain untouched. After reading one or more of these books, have your students join the debate. Does the knowledge gained from archaeological research outweigh the beliefs that burial grounds should not be disturbed? Is it enough to rebury the bodies once they’ve been studied?

Other Ideas

Time Capsule

It occurred to me that each archaeological dig described in these books is like a time capsule. They capture what life was like for that person or people at the moment in time when they became buried or lost at sea. There are some good ideas here: http://www.timecapsule.com/time-capsule/how-to-make-a-school-time-capsule

Decoding the Past

The Smithsonian Learning Lab has a lesson about how archaeologists interpret artifacts called “Decoding the Past.” If you download the PDF, you will find an article on the subject and worksheets for some related activities. https://learninglab.si.edu/collections/decoding-the-past-the-work-of-archaeologists/AUq5scPw1RXKYyNy

Archaeology Activities

The Society for American Archaeology has a ton of activities for students, including a few about the Iceman (featured in Mummies Exposed!). https://www.saa.org/education-outreach/teaching-archaeology/k-12-activities-resources

 

I hope you and your students enjoy exploring these books and activities. If you have any suggestions for how you make archaeology and history come alive, please share in the comments below!

STEM Tuesday — Pets — Writing Tips & Resources

Using Super Senses

Most humans rely on their eyes to learn about the world; sight is our dominant sense. But as you learned last week, life is far different for our furry friends. They don’t see nearly as well as we do.

So how do dogs and cats make up for their less-than-stellar vision? They use other, supersensitive senses like smell. Did you know dogs have 40 times the number of scent cells humans do? And both dogs and cats use whiskers to make sense of their surroundings. I learned these fascinating facts from this month’s books about our beloved pets. And comparing and contrasting our senses led me to think about how authors use our senses — and sensory details — when writing.

Souping Up Sensory Detail

Writers have a superpower. They can magically teleport readers into a book. A good book sucks the reader into the action. It’s like being in a favorite movie or video game. How do writers perform that trick?  Sensory details.

Since humans rely on vision, our natural inclination as writers is to provide lots of details related to what we see. For example, we might write, “A pink starfish clung to the gray rock.” Pink and gray are both visual details.

Yet to truly capture a setting, we must act more like dogs and cats and employ our other senses too. What does the starfish’s ocean home smell like? If you could touch the starfish, would its skin feel lumpy or smooth or rough? What does the sea smell or taste like? Is it salty?

To help you make the shift to your other four senses when writing, try this exercise.

  1. Highlight sensory details in your work. First, pick a paragraph. Then grab a pack of highlighters or colored pens. Highlight any details you included about sights, sounds, smells, textures, and tastes. Use a different color for each sense. Do you notice a pattern? Is your writing packed with visual description? Are there senses you’ve left out entirely?
  2. Close your eyes. Imagine yourself in your setting or sitting next to your character, and think about what you might hear, smell, taste, and feel. Real writer tip: If you’re writing about a place you’ve never visited, find a video online and listen. Or, take a trip to a local museum, zoo, or aquarium to suss out smells, sounds, and even textures if you can find touch tanks or petting programs.
  3. Revise. Go back to your paragraph and add sensory details that help give your reader a fuller picture of the world you’re writing about.

This is a technique I use each and every time I revise. I hope it helps you too!

STEM Tuesday– Pets — In the Classroom

We all love our pets, from the biggest dogs to the tiniest hamsters. They inspire and amaze us with their crazy antics and incredible abilities. In the classroom, students can delve into their interest in pets and other animals with high-interest activities that explore the science of how and why our pets behave the way they do. In this activity, students will conduct an experiment to see if dogs can tell the difference between colors.

Can Dogs See Color?
To start, learn as a class about how dogs see by reading through Inside of a Dog, Young Readers Edition: What Dogs See, Smell, and Know by Alexandra Horowitz and Dog Science Unleashed by Jodi Wheeler-Toppen.

This title offers readers fun science-based activities and experiments to do with their pets based on how the animals think, move, drink, and more.

 

 

To introduce this activity, explain to students how in animals, including humans, the eye and brain work together to translate light into color. Light receptors in the eye send messages to the brain. The brain processes this information and tells us the color we see. In the human eye, there are three types of color receptors called cone cells. Cone cells detect red, blue, and greenish yellow. Together, these cone cells allow us to see the full spectrum of colors.

What about dogs? What colors, if any, can they see? Unlike humans, dogs have only two types of cone cells which detect greenish blue and yellow. Explain to students that they will perform an experiment to test a dog’s ability to see color.

Materials
• Construction paper in different colors – red, green, and blue
• Two glass jars or cups of the same size
• Tape
• Dog treats

Procedure
Because most schools do not allow pets in class, explain to students that they will be conducting fieldwork at home and then analyzing their results as a class. You may assign students to small groups so that every group has a dog for fieldwork. Explain to students the procedures that they will follow at home to conduct their fieldwork.

Fieldwork Steps
1. To begin, students will cover each jar with one color of construction paper.

2. With the dog out of the room, place the blue and red jars on the floor. Bring the dog into the room and tell him to come. When the dog comes to the blue jar, give him a treat. If he goes to the red jar, do not give him a treat. Repeat the process several times and switch the position of the jars. Continue to give the dog a treat every time he chooses the blue jar over the red jar.

3. Take the dog out of the room. Add the green jar to the red and blue jars. Call the dog into the room and tell him to come. Which jar did the dog choose? Continue to give him treats for choosing the blue jar. Repeat 10 times, moving the positions of the jars each time. How many times did the dog choose the blue jar? Record the results.

Back in the Classroom
Have students organize the results of their fieldwork. They can create graphs, charts, or other visual displays of their data. Have each group present their data and discuss their results.

To encourage classroom discussion, have students discuss the following questions:
1. Based on the data, do you think dogs can see color? Which color(s)? How do your results support your answer?
2. Did the breed of dog affect the results? Why or why not?
3. Did any other factors affect your fieldwork and results? How?
4. What other experiment could you design to test if dogs can see color?
