The Science Behind Going Back to School

As school starts back up, we have to get into our “school year habits” and routines, but before we blindly go back to our school habits, we should figure out the science behind everything we do when we go back to school!

Waking Up Early:

During the summer, kids don’t always have to wake up at a certain time. This leads to waking up later in the mornings, and sometimes it even results in waking up in the afternoon.

What most people don’t understand, though, is that there is so much science involved in the simple process of waking up!

There are at least 11 neurotransmitters that play a role in going to sleep and waking up. Of those neurotransmitters, the Orexin neurotransmitter, produced in the hypothalamus, is known to be linked to wakefulness.

The Morning Routine:

When you create a new routine or a schedule, there are health processes involved in that. Your brain identifies the routine and gets you in the habit of following the routine every day.

Sooner or later, you will complete the tasks on your schedule without realizing that you’re following your routine.

Your brain just gets used to the tasks and makes you complete them.

The Ride to School/Work:

When you get in the car/bus/train, get on the bike, or even walk and head to work or school, there is SO much science involved in that!

Cars, buses, trains, and bikes are all works of engineers and scientists that designed and planned every aspect of those ways of transportation.

When you walk, that is a completely scientific process! There are muscles and bones and limbs and neurotransmitters all involved!

The After-School Relief

The first days of school can be draining, and a lot of it has to do with mental processes.

Before you go to school, you feel a mix of emotions ranging from happiness to nervousness to angriness (because your summer was too short).

After the first day ends, however, you feel relieved and happy that the day is over.

All of these emotions are controlled by your brain, and they simple scientific processes that dictate how you feel.

Going back to school is a terrifying and exhilarating experience!

Before you get scared or nervous, think about how those emotions are just scientific processes that your brain controls. If you think about it that way, you can control your brain to make you feel excited!

Hopefully everyone’s first days of school went well, and we wish for everyone to have the best school year yet!


Gender Neutral Toys for the Future of Children

Boys are supposed to play with toy cars and construction toys, and girls are supposed to play with dolls and kitchen toys, right?

Wrong! For the future of STEM fields, we need gender neutral toys!

Check out this paper written by Christie Pearson!

The Importance of Gender-Neutral Toys in the Future of STEM

Gender-typed toys are not effective in fully developing children’s academic, artistic, cognitive, musical, and physical skills.  In addition, they perpetuate stereotypes that can limit a child’s scope of possibilities for future education and professional aspirations.  Toys are children’s tools for exploration and discovery.  They are not only a fun part of childhood, but necessary in a child’s development.

Judith Elaine Blackmore, professor of psychology and assistant dean at Indiana University-Purdue University, conducted two studies that evaluated the perception of toys and their effectiveness in child development.  The toys were categorized as strongly feminine, moderately feminine, neutral, moderately masculine, and strongly masculine.  She found that “strongly gender-typed toys appear[ed] to be less supportive of optimal development than neutral or moderately gender-typed toys” (“What the Research Says: Gender-Typed Toys”).

The division instilled during childhood playtime plays out in higher academia and the professional world.  “Despite accounting for half of the college-educated workforce, in 2010” only 13% of engineers in the United States were women (“Science and Engineering Indicators 2014”).  Since the late 1980s, there has been a movement to increase the number of women in science, technology, engineering, and mathematics (STEM) disciplines.  Gender parity initiatives have worked to increase enrollment in higher educational through scholarships and STEM programming in elementary, middle, and high schools.  Many of these efforts have been successful, and at Southern Methodist University’s Lyle School of Engineering there is a 33.3% female enrollment rate as of the Spring 2015 semester.  The Lyle School is also unique for having at least 30% female enrollment rate for the past ten years.  While this percentage is progressive, there is still room for improvement.

The problem is clearly visible in the toy aisle where gendered-typed toys are maintaining the barriers of gender stereotypes.  In 2012, Debbie Sterling created a Kickstarter account to make her prototype of construction toys for girls a reality.  Barely three years later Sterling functions as the founder and CEO of GoldieBlox, one of the most popular toys for girls.  GoldieBlox is helping to blur the lines between gendered-typed toys, creating construction toys for girls, ages 4 to 9, by incorporating verbal skills with spatial skills (Sterling).  Sterling does not seek to replace dolls; on the contrary, she seeks to incorporate engineering and math in young female play.  She is quoted on the GoldieBlox website saying, “There’s nothing wrong with being a princess, we just think girls can build their own castles too.”

The toy aisle should not be divided by assumed gender stereotypes.  Girls and boys are different, but their opportunities don’t have to be.  Playrooms are children’s first classrooms, toys their first textbooks, and their imagination the curriculum.  The current education system requires all male and female students to take core classes: English, math, and science, in primary education.  In order to better prepare young children for success in the classroom and beyond, we should bring our children to a toy aisle that stocks an endless array of opportunities for all.

DSC_5687 DSC_5710 DSC_5731

Everyone had a lot of fun and learned a lot during our camp, and we are sad that it had to come to an end. We can’t wait until next year!


SMU CSI Camp Session 4 Day 2

Today was the second day of our last session of SMU CSI Camp 2015.

We started the day off with an exciting presentation by the FBI. Our campers learned a ton about being in the FBI and how cool the job really is!

DSC_5438 DSC_5439 DSC_5450

After learning all about the FBI, our campers went to do a Fingerprint Dusting lab with the SMU PD, and they also got to find out what kind of fingerprints they had with our Fingerprint Sensor Activity!

DSC_5453 DSC_5463 DSC_5504 DSC_5505

After learning about their fingerprints, our campers got to learn about the SMU Police Department and the SMU SWAT Team. They got to learn about what the SWAT Team does, and they got to see some cool equipment!

DSC_5557 DSC_5536

After learning about the SWAT Team and cool equipment, our campers got to extract DNA from strawberries! They got to squish the strawberries and mix the strawberries with other things to get the DNA!

DSC_5563 DSC_5612 DSC_5611

After the DNA Extraction, our campers got to look at their eyes and do an Iris Recognition Activity!

Today was a ton of fun, and the campers learned a lot!

We are sad that our camps for the year are ending, but we are glad that everyone has had such a wonderful time! We definitely cannot wait until tomorrow!

SMU CSI Camp Session 4 Day 1

Today begins the first day of our last SMU CSI Camp for this summer.

We have a great group of campers who are ready to learn and solve crimes!

We started our day with a presentation by detective Sean Kearney. He taught us everything we needed to know before going into our own crime scene!

DSC_5187 DSC_5201

After learning from him, we were ready as we stumbled upon our own crime scene! There was a kidnapping in the Caruth Institute, and we needed the best group of young minds to figure out who committed it! Luckily, we had them! Our campers joined together to examine the crime scene as they collected evidence, took pictures, and sketched the scene.

DSC_5208 DSC_5262

After examining the crime scene, the campers took a break from it and got to meet a K9 officer and his partner! He explained his job and how him and his dog solve crimes! After hearing about the officer’s job, we went outside to see a demonstration of how the officer and his partner work together!

DSC_5356 DSC_5376

After the K9 presentation, the campers returned to the classrooms to see if they could solve the crime we discovered at the crime scene. We took a sample from the soil we found at the crime scene and observed it under the microscope to see if we could find any clues.


After looking at the soil, we did a paper chromatography lab to see what marker was used on the note we found at the crime scene! Every company uses multiple colors to make up the black marker, so we were able to see different colors in different markers, and compare them to the note to figure out which marker was used!

DSC_5426 DSC_5431

The campers learned a lot today! We can’t wait to continue our camp tomorrow!

SMU CSI Camp Session 3 Day 3

Today was the last day of our third session of SMU CSI Camp.

As we were all sad that the great time at camp was coming to an end, we were also all excited to see what great science adventures the day had in store for us!

We started our day with a visit from Dr. Amy Gruszecki, a forensic pathologist. She explained what a day in her job is actually like. To our surprise, her job is nothing like what they depict on TV!


She showed us pictures of things she examines as well! The picture below shows an artery in the heart – the one on the left is good, and the one on the right is blocked!


As the day went on, we did forensic anthropology and a gait lab!

DSC_5026 DSC_5043 DSC_5057

After this, the campers got to do a facial recognition lab! With this activity, our campers got to apply knowledge they learned throughout the week, and they got to learn even more!

DSC_5093 DSC_5088

We also had a visit from Jose Gloria and Ruth Spencer of the Denton County SWAT Team! The girls got to see all their equipment, and they even got to play with some of it!

DSC_5104 DSC_5128 DSC_5164

Session 3 has officially come to an end, and we are so glad that it was so much fun for the campers! Not only did we all have a ton of fun, everyone learned a lot and got to apply their new knowledge throughout the week!

After such a great session 3, we absolutely cannot wait to start session 4 next week!

SMU CSI Camp Session 3 Day 2

This morning was the second day of our third session of SMU CSI Camp!

The day was filled with a ton of exciting science activities, and everyone had a lot of fun!

The morning began with a presentation by a real FBI Agent! The campers learned everything they wanted to know about the FBI!

DSC_4882 DSC_4883

After the FBI presentation, the girls worked with the SMU Police Department and learned all about fingerprint dusting.

DSC_4884 DSC_4892

After fingerprint dusting, the campers wondered what kind of fingerprints they had, so we decided to complete a fingerprint sensor activity. Through the fingerprint sensor, the girls learned what kind of fingerprints they have, and they also learned what minutiaes are!

DSC_4905 DSC_4911 DSC_4916

After this, Detective Perez came in from the SMU PD and gave a presentation about women in law enforcement and more! Detective Perez showed the campers what she does to get in full uniform; she discussed what she carries on her belt, and the campers learned what all is carried in a police vehicle.

DSC_4921 DSC_4931 DSC_4941 DSC_4972 DSC_4974

After learning about law enforcement, the campers were curious to see what our next exciting activity was. The girls got to extract DNA from strawberries!

DSC_4987 DSC_4995 DSC_5007

To wrap up the day, we did an iris recognition activity!

DSC_5010 DSC_5011

Today was so much fun! We can’t wait until tomorrow!


SMU CSI Camp Session 3 Day 1

Yesterday was the first day of our second girls camp!

We have 10 eager 6th and 7th grade ladies this week from the DFW, Houston and Oklahoma area! We began our day with a presentation by a detective from the Dallas Police Department about being a Crime Scene Technician. He told us everything we needed to know before we entered our crime scene.

DSC_4736 DSC_4741 DSC_4754

With the information we learned from our Detective, we started surveying our crime scene. We sketched out the scene, took lots of pictures and collected the evidence.

DSC_4758 DSC_4769 DSC_4772 DSC_4813

After lunch, we got to meet K9 Officer Shane Menz and his partner from the Lewisville Police Department. He explained his job and how he and his partner work together to solve crimes. He showed us how he detects narcotics and how he is focused on his job at hand. As a reward he gets to play with his favorite toy, his squeaky ball.


We then went back to the evidence we found at our crime scene. The note that was left behind was hand written with a black marker, so we did a lab called Paper Chromatography to find out what kind of black marker was used to write the note. Did you know that black markers are actually made up of different colors and each company uses different colors in their black markers?

DSC_4861 DSC_4863 DSC_4867

We then took the soil sample that we collected at our crime scene and analyzed it under stereoscopes. We compared it to other samples taken around the location of our crime to find out where it came from.

DSC_4874 DSC_4876

It’s was an exciting first day! The girls can’t wait to continue their investigation today!

SMU CSI Camp Session 2 Day 3!

Today was the last day of our second session of CSI Camps.

Everyone was sad that all the fun was coming to an end, but everyone was also excited about the cool new things they were going to do today!

We started the day off with a presentation by a Medical Examiner!


Then we did some forensic anthropology!

DSC_4549 DSC_4552

After learning about all those things, we did a gait lab!

DSC_4570 DSC_4575

Afterwards, the Denton SWAT Team visited, and we got to explore their field of work – which was a ton of fun!

DSC_4590 DSC_4659 DSC_4707

The last science activity for the day was a facial recognition lab, in which campers applied knowledge they gained throughout the three days, and they got to learn more!


This group of campers was incredibly talented, and wanted to learn all they could from the camp.


It was a great three days, and we can’t wait for session 3 to begin!

SMU CSI Camp Session 2 Day 2

Our investigators were eager to start the day today, and they were right to do so!

The day started off with an FBI presentation!


After the FBI presentation, the boys did some cool labs!

The first was a fingerprint dusting lab!


Then, they did a fingerprint sensor activity!


Campers were then wowed by the SMU Police Department and SWAT Team!

DSC_4387 IMG_0310IMG_0330

To conclude all the excitement, today ended with two fun labs!

First was the DNA extraction lab:


Lastly, the campers did the iris recognition lab, which everyone enjoyed!


The campers can’t wait to learn more about science and do cool labs tomorrow!
