T. Rex Tracks: A Math and Science Activity with Turtle Trails Publishing

I am thrilled to share this guest post from my friend Carla from Turtle Trails Publishing. You may also know her from the excellent learning activities she shares at Preschool Powol Packets and Teaching Without Chairs. Your kids are going to love getting outside and trying this dinosaur-themed STEM activity!

Tyrannosaurus Rex is one of the most popular dinosaurs of all time for a lot of reasons, but how much do you actually know about this dinosaur? I have an awesome science + math activity you about T. Rexes for you and your kiddos today!

T. Rex Dinosaur Math and Science Activity


Hi! My name is Carla Mae Jansen, and I recently finished writing A Dinosaur Made Me Sneeze, a picture book about the rock cycle (more on that below!). Anyway, since I’ve been working on this book we have been doing a ton of dinosaur activities lately--partly because the book is on everybody’s minds and partly because we all love dinosaurs! Seriously, I think there’s a part of me that will be seven forever.

Anyway, today I’m excited to share this T. Rex Tracks activity with you! It’s a low-prep, easy to do dinosaur activity that has your kids use science reasoning and math skills to create T. Rex “tracks!” 

Simple Supplies:


1- Track Markers (masking tape OR paper OR sidewalk chalk if you’re outside!)
2- Measuring tape or rulers

Easy How To:


1- To begin, ask your kids to guess how tall their legs are. Most kid legs will be 2-3 feet high. Tell them that most T. Rex legs were about 11 feet high! Measure 11 feet high along a wall, and see where the T. Rex leg would be! The rim of our basketball hoop was right at 11 feet...and yes, my 7 year old can climb straight up to it!

2- When we did this, I told the kids that since T. Rex legs were so tall, their steps were HUGE! But before we looked at T. Rex steps, let’s see what kid steps look like. Let the kids work in teams to mark a set of kid “tracks” showing at least 10 steps.  Is this different if they run?

3- Ask your kids how many kid steps they think would fit inside of one T. Rex step (or stride). If you have paper, write down their guesses. Since we were outside, we just talked about it.

4- Ask the kids how they can figure out how many kid steps fit inside on T. Rex step. It might help them to know that T. Rex steps when walking were about 5 feet long and when running were about 12 feet long!  According to our measurements, my 4-year would have to 6 steps to keep up with a T. Rex, my 7-year old would have to run 4 steps for every 1 T. Rex step, and my 10 year old would have to run 3 mighty leaps to keep up.

How close were their guesses from #3?

T. Rex Fun Fact: Some researchers believe that T. Rexes could have run up to 20 miles per hour, but would not have run faster than that because if they were to fall going any faster the crash would have killed them!

To finish off the fun, we read A Dinosaur Made Me Sneeze!


This is my new dinosaur-themed, science-based picture book!  It’s a delightful rhyming story that introduces rock cycle science (complete with vocabulary like “sedimentary,” “igneous,” “metamorphic,” and more!) with fantastic characters and a hilarious story! It showcases the changes that the Earth and rocks on the Earth make as years go by. You can learn more about it, see some of the illustrations, and more HERE! I really hope you love it!!

I hope you have a “roar-some” time with your T. Rex tracks!! 

Thanks again for letting me join you, and happy educating!

40+ STEM Activities Using Materials You Already Have

I've scoured the 300+ posts on Share it! Science to find over 40 hands-on science, STEM or STEAM activities that do not require special materials and can be completed with things you most likely already have at home. In a few cases I have made suggestions of possible substitutions for materials as well. With a little flexibility and creativity we can work together to give your family a fun experience at home (as well as sneaking in some learning...but don't tell the kids!)

Whether you are stuck close to home due to school closures, or just stumped on what to do with your kids over a vacation you are sure to find something here that will keep you busy! So, raid the recycling bin, check out the craft drawer and start learning and having fun.

Making, Building and Experimenting Activities 


Kids love things that move! You can build a zany Rube Goldberg machine out of recyclables or just about anything else you have in the house. What task will your machine accomplish? Feeding the dog? Cooling you off on a hot day? Squeezing toothpaste out of a tube? The possibilities are endless with this one!

Encourage the kids to be spies and CSI's with this (ink-free) fingerprinting and (heat-free) invisible ink activity! Explore loops, whorls and arches and other unique patterns in your fingerprints and create and distribute some secret messages. You probably have everything you need right in the kitchen!

Have a flashlight, white paper, water, an old cd? Just a few of the things you can use to make a real rainbow indoors! Learn how to make 5 different rainbows from just a few common household items.

Save your toilet paper rolls and try this challengeHow much weight can a toilet paper tube hold? How about an egg?

Science in the kitchen! This outlines a decomposition experiment with apples, but you could substitute any food you've got on hand. 

Build a marble roller coaster! This is so much fun for kids and adults alike. You might not have the tubes I've used in this post on hand, but you can use just about any recycled container to create a little roller coaster.

STEAM: Activities that include Art


You'll find several STEAM activities in this post outlining a family STEAM (Science, Technology, Engineering, Art and Math) event at my school. These are all fun for the whole family.

Grab a container from the recycling bin and build a zoetrope, then have the kids make some simple animation. This is always a hit with older kids. **Depending on the size of your container you may need to adapt the measurements. (We have faith in you!)
