Holiday Science: Gravy

What’s so scientific about your holiday gravy?  Isn’t gravy just, well, food?  Food we put on mashed potatoes and turkey at Thanksgiving and Christmas and Sunday and, well, pretty much any time?   How could gravy have anything to do with science?

Yummy! But science?  How in the world. . . .
Yummy! But science? How in the world. . . .

Here’s the thing, drooling holiday turkey & gravy lovers:  gravy-making is all about the science of starch.

Starch?  That white powdery stuff Great-Grandma used to make her handkerchiefs and your Great-Grandpa’s boxers smooth and stiff?

Yep.  Exactly.  Only in the kitchen, we use white powdery stuff made especially for use in food.  Otherwise, it’s the same stuff.

Starch is plant-based, and many people use wheat or corn-based starches to make gravy.  I like to use corn starch*, as flour (wheat-based starch, no joke!) adds its own flavor to gravy whereas corn starch does not.  Both, however, require some fancy whisking to get all the lumps out!  (If you’ve ever had to choke down lumpy gravy, you’ll appreciate the extra effort put into smooth gravy!)

A kitchen whisk makes stirring lumps out of gravy a lot easier and quicker!

What is starch, exactly?  Interesting question!  Starch is a complex carbohydrate.  To put it more simply, starch is a fancy chain of sugars – fancy, because while sugar dissolves completely in liquid, starches absorb the liquid, rather than disappearing completely in it.

If you added a heaping tablespoon of sugar – white or brown – to your skillet of hot turkey fat, it would simply disappear, completely absorbed by the liquid.  But if you added a heaping tablespoon of cornstarch or flour to that same skillet, it would start bonding with the fat and the entire contents would start to “gel.”  Add a little salt and some milk to your skillet, keep stirring, and in a few minutes, you’ll have delicious gravy, table-ready to pour right onto your mashed potatoes and turkey slices.  Without the addition of milk, your gravy would be too stiff to ladle out!

If you use flour as your starch, your gravy will be a little “stickier” than gravy made with corn starch.  Many people prefer that, and many people do not.  Your call.  If you have a gluten allergy, use corn starch – flour contains gluten.

Take a quick scientific peek at what you’re adding to your gravy:

Simple starch molecule

You see?  I TOLD you gravy was scientific!

Especially for you cooks, here’s a simple recipe for holiday (and any other day) gravy:

In a large skillet, heat (on low) 1 cup of turkey drippings (or ham drippings, or bacon drippings, or butter), stirring constantly.  Sprinkle one heaping tablespoon of corn starch onto the drippings, still stirring constantly.  When the mixture begins to bubble, SLOWLY add milk (or water if you don’t want your gravy as rich) and still stirring constantly.  Switch out your spoon for a whisk, and begin slowly whisking the mixture.  It will start to firm up very quickly.  When it’s the right degree of firm to your taste, remove from heat and pour into a gravy boat or bowl.  Take it to the table and start eating.  Gravy should be served and eaten immediately, so it’s probably going to be the last thing set on the table before everyone dives in.  If gravy has to sit and wait, the consistency changes.  That’s scientific, too.  Look it up.

Make a big batch; gravy freezes nicely, and there’s something about turkey gravy in the spring. . . .

Don’t think it’s just wheat and corn that contain starch.  Loads of vegetables, legumes, and grains are starchy.  Potatoes,  pumpkin, sweet potatoes,  all kinds of beans, peas, rice, and tons of other foods are starchy.   Don’t try to make gravy with all of them, though.

*Yes, indeed, the same corn starch we use for our non-Newtonian liquids!  In fact, gravy IS a non-Newtonian liquid!

Not Everyone Hates The Science Fair!

Science Fairs get a lot of bad press these days, and I don’t like it. Honestly? I think the only bad science fair is a science fair that a child is FORCED to enter every year.

You heard me. The science fair should be 100% voluntary, most of the time.   Maybe it would be better if fifth grade, for example, was a mandatory year, and all others were voluntary.

I fully understand that this stance will not make me very popular with a few science teachers, but as I am a science teacher and a parent, I have a right to my own opinion, which is based on personal experience as are all opinions.

Don’t get me wrong – I am a HUGE fan of science fairs. My own children looked forward to it every year, from K-8, and even while a few other kids were kicking and screaming and whining and claiming it wasn’t FAIR, the fact is, it was absolutely fair. The fair was fair.

This picture went viral recently, all over the internet.

Please click the link and read Ms. Messina’s article at the Huffington Post about how and why she created this poster!

This poster was created by Susan Messina, who is not at all against science fairs – just the ones that force kids who aren’t interested to participate, too. Her article over at the Huffington Post is very interesting and informative, and will give you the background into why she decided to make the poster.

Ms. Messina suggests that if the science project is required, then it could be a family project which would allow students and parents to work together collaboratively. I disagree, unless the assignment is for a group project. I think any assigned project should be an individual thing.  Families may, and should, provide encouragement and help with supplies, and the occasional suggestion, but mostly, parents and siblings need to stand back and let the student create. However, if the assignment IS for a group project, then the science fair is the perfect chance for the entire family to learn together!  Otherwise, let the student create the project and show his/her family the creation, complete with hypothesis and experiment and results.  It’s good practice for the judges!

Parents who shamelessly do the science project themselves ruin it for all the families who do it RIGHT.

Years ago, my son was the only one in his kindergarten class to submit an entry to the science fair at his school.  He was obsessed with sea creatures at this time, and with pirates.  His project kind of reflects both interests.  Please don’t call CPS on me; he’s a grown man now.

Andy's diorama.  He had just turned 5.

Now, a diorama is NOT a science project, but for a kindergarten student who had had no instruction and who insisted on entering the science fair even though his teacher and the fair judges weren’t sure if a five-year-old qualified, I think it’s pretty good.  When the judges looked closely, I saw their expressions change and they convened for a chat.  Can you figure out why?

He'd read that pirates sometimes disposed of prisoners this way.

He told the judges that he wanted the bottom of the sea to look interesting.

He wanted to illustrate what happened if a pirate went swimming in infested waters.

His favorite stuffed toy was a big red octopus we got for him at Epcot.  He wanted to include Big Red in his diorama in such a way that people would remember him.

The octopus is my favorite part of Andy's diorama.

And, he loved tubeworms.  He tried to draw a coral reef but he didn’t think pirates would dispose of a prisoner via the cement shoe route near a coral reef.  “Too many onlookers.”  He may have been only five years old, but even then he was looking ahead.

tube worms

Remember now, that a diorama is NOT a science experiment.  Do not encourage your kids to try to enter a diorama or demonstration or poster as a science project.  My little son, when asked, was able to explain the science behind why cement shoes would certainly sink a naughty pirate to the bottom of the sea, and how a foolish pirate who went swimming in shark-infested waters would certainly become the first course for a shark’s supper,  He did admit that his soft huggie octopus would probably never try to strangle a pirate, but that he’d included that scenario for effect.

But for a very young child who is only just beginning to learn about the world outside his own home, whatever strikes and holds his/her interest is something well worth encouraging.  Just be there to ask questions and be sincerely interested when your child gives you a lengthy explanation.  Take him/her to the library and look at picture books.

Do experiments in your home.  My son tied gravel to his Batman action figure’s feet to see how many it would take to sink the Dark Knight to the bottom of a pail of water.  He got out his postcard of tubeworms from Marineland to make sure he was drawing and coloring them correctly.

As he grew older, his science fair entries were actual experiments, and in seven years, he earned six blue ribbons.  His final entry, in 8th grade, was about how air pollution is destroying the world’s statues and buildings.  He took eight huge pieces of sidewalk chalk and carved them into statues, mounted them here and there on a paper-mache mountain, and sprayed them with vinegar several times a day, to represent pollution.  Every night he took a picture.

Our buildings and statues are definitely being worn down by pollution.

He wanted to use hydrochloric acid instead of vinegar, but we said “no.”

We did have some locked in the garage cabinet, though.

Doesn’t everybody?

How to Study Density with Popcorn

by Christy McGuire, Contributor

Thanksgiving is almost here! You can use one of the original foods from the first Thanksgiving to discuss density with your students. Popcorn is fascinating because it changes so drastically during the cooking process. The color, shape and texture of a popped kernel are all different than those of an unpopped kernel. If you can spare the day before Thanksgiving break, this simple density experiment would be a great way to practice their inquiry skills, and a great excuse to have a treat in class!

How to Study Seeds with Popcorn/How to Combine Thanksgiving and Science in your Elementary Classroom

If your students have already covered density, this is a great time to practice doing a full exploration complete with a written report. You might simply give them access to the relevant materials and set them loose with this challenge:

Find how density changes for popped verses upopped corn. Check the results of your experiment and write a description of your findings, including an error analysis.

If density is a new concept, or if your students are struggling to get the hang of the scientific method, you can help them figure out the procedure. Make them do as much of the thinking as possible though! Science is more fun for the engineer making the decisions than for the technician doing as he is told.

Leading questions to help students develop their procedures

How do we calculate density? (mass per volume)

What measurements will we need to take in order to find density? (mass and volume)

How do we measure mass? How do we measure volume? (balance, and appropriate beakers)

How are we changing the popcorn? (popping method)

The Science of Popcorn

Hints for a successful experiment

You can expect your popcorn to increase in volume by about 16X.

To  pop the corn over heat, put a couple of tablespoons of oil in the pot or beaker, add corn and heat over medium heat.

If you are using a microwave, you can measure the volume of the popcorn in a bag of microwave popcorn and assume the same volume is in a second bag of popcorn that you pop before class.

Increase accuracy by repeating with varying quantities of popcorn, or by combining data from multiple lab groups.

Science of Popcorn

Data Analysis

If you wish, you can have your students graph mass a function of volume for various amounts of unpopped corn, then do another graph for the popped corn. The slope of these graphs will be the density of the popcorn.

You can also ask your students to compute density algebraically, then graph density as a function of popped or unpopped.

Requiring students to analyze the accuracy of their results could provide some very interesting feedback. Lab groups could compare results with the rest of the class. They can also compare the initial and final masses and try to defend any changes that they find. My experience is that the mass of the popcorn actually increases during this experiment. Don’t tell your students! See what they can come up with to justify their own answers. Factors that they may want to consider include the mass and volume of the oil used to cook the kernels and the humidity on the day of the experiment.

No matter what your students’ level, this experiment can be adjusted to provide a challenging, and interesting exercise. I hope you will enjoy. Happy Thanksgiving!
