Alright stop!   Collaborate and listen.  The Little V’s are back with a brand new invention.  Vantaztic Learning has some mad skills on the mic, but even I can’t touch the brilliance that came from these young problem-solvers.  Your mind will be blown back to the 90’s to when we thought this track was solid,

as you listen to these clever devils collaborate.  See the thought process unfold for yourself as the scientists explain how their prototypes will slow beach erosion.

Some background info for our readers:  The kids spent a day to design a blueprint of how their idea would look and created a write up of how it works.

Day two (this day) was focused on creation of their sketch.  Next week they will test their project to see if it does in fact work, and if for some reason not, back to the drawing board.  For our fourth event day, we’ve invited a couple of professionals from our local community with background knowledge and first hand experience in beach renourishment to visit and listen to the students as they present their ideas, discuss the successes and drawbacks of the pretesting, and share their improvements.  Suppose we’ll have to wait to add more until testing and discussion take place, so for now . . . hit the hi-hat.  Word to your mother.

Engineering a Way to Slow Erosion
Wave Erosion Testing

2/23/17 Mr. Rudolph, “Rudi”, stopped in to listen to the young minds share their ideas and models to prevent beach erosion.  Mr. Rudi works for the Carteret County Shoreline Protection in Emerald Isle, NC.  He shared how to combat the erosion issue with the method Carteret County uses, dredging sand onto the beaches.  Fun Fact:  Sand is classified as sand if it is between 1/16-2 mm in size, any larger and it is mud, and then gravel.  Fun Fact:  An average of 1 million cubic yards are pumped onto the beach for a given project.  Fun Fact:  If sand is the erosion problem, then the solution is sand, putting it back to where it belongs.  The kids were engaged and developed terrific questions such as, “Would my hurt the environment?”, “How much sand is used to dredge back onto the beach?”, “How do you know when too much erosion is happening?”, and “What is your favorite part of your job?”.  Super way to end the week.  We are definitely spoiled to have so many resources at our fingertips.

Coastal Connections: Science in the Field to the Classroom

June 4, 2016 at 9:00 am (Science) (, , , , , , , , , , , , , , , , , )

Below is a thinglink I have concocted to sum up the outreach events and partnering of local organizations relating to the field of science in which the students from the tail end of last year to the current roster have been a part of.  The roster of students of 2015-2016 have had been exposed to so many incredible resources that make our community.  It is uncommon for such a small place to have the vast amount of people working in related fields of environmental, biological, and physical sciences as it does.  These children have had more interaction with scientists throughout the school year than the peers from any region, making them stewards for our community and hopefully sparking a curiosity to pursue a career in a related science field.  In this case, it is good to be spoiled.

None of this could have been possible if it were not for a.) my colleague Lauren Daniel whispering in my ear to join her in this quest with the COHORT and b.) also the Center for Marine Science and Technology (CMAST) to put me in contact with groups such as the Coastal Reserve, Coastal Federation, NOAA, and Duke Lab (to name a few).  This thinglink will serve as my introduction to the National Marine Educators Association in Orlando, FL this summer.  I think the viewers will be impressed with what these young minds have experienced and created because of those experiences.  Please leave comments below if you feel the thinglink lacks explanation.  Just keep in mind these are only captions and I’ll be explaining the activities in depth.  I can always do the same in the comment section.  Thank you and enjoy.

Exploring Circuits

March 9, 2016 at 8:00 am (Science) (, , , , , , , , , , , , , , , , , , , , , , )

We’ve spent some time reading and exploring how to create a static charge.  We now know (I hope we remember) static means to stay still,  We’ve also added current (move), discharge (empty), and insulator (protect) into our repertoire.

We also have predicted and tested items that can conducts electricity vs those that will not.  Last week I attended NCTIES (nerd tech convention) and met a scientist named Steve Spangler, who seems to be on the Ellen Degeneres Show quite a bit.  Cool tidbit, his father invented fake blood.  See any movie ever?  Yeah, that’s his dad’s fake blood on the screen.  He said he was stoked seeing Jaws and thinking how all that blood came from his mom’s nine blenders in their basement.

Anyway  . . .

Thanks to Mr. Spangler, we now have an Energy Stick (find them on Amazon) in which we conducted circuits, safely, through the human body.   We were able to make a class circuit with 4th and 3rd grade combined.  Next we’ll take a scavenger hunt throughout the school to find items that will conduct, allow to pass, electrical currents.  Then we’ll create squishy circuits (home made batches of play-dough) to explore more fun with electricity.  There are recipes for batches that will conduct and those that serve as insulators.  4AA Battery packs  ($2.48 per pack) will be in need – we only have one.  May have to get a Kickstarter or GoFundMe! Enjoy the learning.

Engineering Ideas: Irrigation

January 23, 2016 at 9:00 am (News) (, , , , , , , , , , , , , , , , , )

Meet a group of engineers applying logical reasoning, problem-solving, and mathematical concepts to create an irrigation system to make water flow three feet (without leaking) and disburse into two separate cups evenly.  Students were split into teams to devise an irrigation company name.  These company’s were given a $500,000 budget to use towards materials needed for construction, but before being allowed to purchase, they needed a blueprint design of the construction.  Each member created an illustration and the members of each team voted on which design to use based on budget and style.  After blueprints were approved by the inspector (yours truly), they were allowed to purchase the needed items, such as plastic tubing, cups (plastic & Styrofoam), duct tape, pvc, clay.  All of these items ranged in price by foot and inch from $2,000 – $25,000.  Each company was responsible for keeping up with the budget and making modifications to the blueprints prior to changing the construction.

Prior to beginning this project, we researched what irrigation was, how the Roman Aqueducts were constructed and worked, and focused on ethical procedures – which tied back to our previous knowledge from lessons on deforestation and the estuary/dragonfly pond activities.  With every good intention there usually is some negative impact or consequence.

Irrigation Construction

With that, company’s went to work figuring out how their constructions should be made, placed, and would work.  To keep the ethical point in mind, we added a stipulation.  Teams had three chances to make their irrigation system work without springing a leak.  However if a leak occurred, a company would have to shell out $50,000 for EPA violations.  The issue the people in Flint, Michigan are experiencing with water quality or lack their of would appreciate this.  If a company was successful after three attempts they went on to become a multi-million dollar sought after mogul.  If a company was unsuccessful due to leakage or blockage of water flow, then they most likely went out of business.  However, some unsuccessful company’s had ideas to merge to pool together budget and materials.

There were many purposes to this lesson.  The subcategories are:

  • Did the students work as a team?
  • Did everyone play a role?
  • Did their system work?

Students will self evaluate their experiences during this activity when we return.  Thank you to http://www.tryengineering.org for the lessons (some modifications were made).  Enjoy their creations.

Thar She Blows

September 11, 2015 at 3:57 pm (Science) (, , , , , , , , , , , , , , , )

This week we researched the differences and similarities between ancient and modern day sperm whales (Thanks KidBiz), and we also revamped our comparing skills with the use of whole numbers and fractions for our place value unit.  So why not keep the ball rolling by comparing life size whales of different species?  The scientists spent the afternoon comparing and contrasting modern sperm whales vs narwhals, studying their traits and how they provide advantages for survival.  We are currently in the mix of creating our own bird and/or fish species and will share these in the weeks to come.
