May The Force Be With You

Well, it isn’t May yet, but the force is strong with these students.  The content of this topic scaffolds upon grade level.  Our first graders began exploring how gravity and slope change the rate of speed an object travels.  They began building ping pong ball mazes from cardboard, making modifications to their slope for how fast or slow they wanted their ball to travel as well as alternating direction.  Week 2 was spent investigating magnetic properties of pushes and pulls.  They rescued paperclips from drowning in a cup of water, worked on their “magic” magnetism by levitating items, and testing magnetic strength via stacking materials between a magnet and magnetic object.  Then in week three, third graders focused on balance in motion.  This week was dedicated to exploring how to balance a variety of objects and what balance means.  From their they created cars out of index cards, straws, tape, and life savers in which the goal was to have a vehicle that would steer straight by looking at symmetry of vehicle design of the chassis, wheel axles, and placement of tires.

Third grade is currently using Hot Wheels to build tracks to test variables of speed, distance traveled, vehicle design, and engineering a safety harness to protect LEGO figures.  Their week two will consist of building parachutes to slow the rate of fall for ping pong golf, rubber, and Styrofoam balls.

Fifth grade engineered Slinky spring scales to calibrate the weight of objects and test their results verses the digital scale read-out.  Then the used genuine spring scales to test surfaces areas and the amount of friction produced by pulling wooden blocks across  linoleum, carpet, sandpaper, wax paper, foil, and rubber mats.  The third installment to their force unit was calculating the speed of vehicles.  For this activity fifth graders used pull back ATV’s, adding  weight after each series of three trials.  Then they compared the results and created graphs to represent the speed and distance.

Hopefully we’ll be  back before the school year lets out for another episode of Vantaztic Learning.  May the 4th be with you.

Hello, My Name is Phil. Phil Ter.

Welcome back to the show.  This latest episode on #FullSTEAMahead is all about our innovative 4th graders and their study of detritus feeders.  These students have discovered there are benefits and drawbacks to any given environment.  This week fourth graders focused their attention to our nearest estuary, the Bogue Sound, with particular interest on a specific marine critter that generates millions of dollars ($5.5 million in 2017 to be exact) for the state of North Carolina a year.  Take’em raw or let’em boil.  You can shuck’em.  You can suck’em.  Just be careful where you get’em.  Yes faithful readers we are learning about those detritus feeders known as oysters, Mother Nature’s natural Brita system.

On Monday we engaged in an estuary card game provided by the North Carolina Coastal Reserve in which every player begins with ten goldfish crackers to represent their estuary.  There is also a pot representing a “larger estuary” to pull from if needed.  Students take turns drawing and reading the information on the cards to one another.  If lucky you might draw a card that reads something like, “Sea grass has been planted around the perimeter of the estuary, preventing erosion to creep into the water.  Add three fish from the pot.”  OR sadly one might draw a card reading, “Farmer Fred’s hog farm lagoon overflowed and the waste created an algal bloom sucking all the oxygen out of the water.  This caused a fish kill, lose all your fish.”  At this point, students would have a full belly eating all of the crackers they accumulated.

On Tuesday we were visited by a good friend and neighbor Rachel from the North Carolina Coastal Federation.  She brought her storm water runoff table to demonstrate how pollutants enter our waterways.

On Wednesday, the class took a stroll out to the rain garden.  We identified the various plants established, discussed the rain garden’s purpose, looked for physical debris the plants have caught, and noticed the huge pile up of asphalt caked around the first line of defense (the river rock).  We will revisit the rain garden to weed out invasive plants sprouting through, trim back the Muhly Grass once the purple feathering fades, pull back the river rock to lay out more newspaper and landscape fabric, and shovel the asphalt out.  We returned to the STEAM lab to be welcomed by oysters (on loan from the Carteret County Community College’s Aquaculture Center).  Watch them clean the tank in lapsed time.

Our detritus friends stopped by to demo how they filtrated water, keeping the Bogue Sound clean.  While these critters filtered phytoplankton, our students began to brainstorm items they could use to create their own filtration system.  They sketched their model and labeled the materials they planned on using for the build day.

Finally, on Thursday the students began selecting the materials from their blueprints to begin construction.  They pulled from previous ideas from the week.  Rocks were selected much like the ones that act as a defense line around the perimeter of the rain garden.  In addition to the pebbles, sand, marbles, and bottle caps were at their use.  They recommended cotton balls, shredded paper, and coffee filters to absorb pollutants.

The end results were Vantaztic.

Sum of Its Parts

“No problem can withstand the assault of sustained thinking.” – Voltaire

Fifth graders applying their know-how of when something is disassembled it should (in theory) weigh the same as when in one piece.  We borrowed a NASA activity, tweeked it a bit to tie in this standard with the objective of building a satellite.  We used Legos, with each style representing a specific instrument provided the NASA list.  In case you are wondering, the answer is an emphatic yes.  Yes I weighed every Lego piece/style to the tenth of a gram.  #Ihavenolife

Moving forward:  Here is how the spiel went . . .

“By now you’ve learned the weight of an object is equal to the weight of the sum of its parts. This is true in all closed systems. So let’s apply your knowledge of this skill to build a satellite. Each part of a satellite has a specific job, and some satellites have different jobs than others. Some are used to take photos, some satellites measure gravity, some measure temperature, and there are even satellites that scan a planet’s land formations. In fact, there are way more instruments built on satellites for many other jobs not mentioned . . . yet. One thing all human made satellites have in common, is that they are made up of different instruments (pieces) that all weigh different amounts, and all of these parts need power.”

First students watched two clips provided by NASA, then journaled responses:
Video 1 – Why is a good idea not enough to build a satellite?
Video 2 – What obstacles do you need to consider before building your satellite?

Next they create a team of four people. Their job as a team is to . . .
1. share your notes from the two videos.
2. decide what you want your satellite to do.
3. make sure everyone is included and involved in this mission.
4. develop a team name.

Notes in google classroom before moving ahead (STOP STOP STOP STOP STOP: Before you can proceed, you will need a teacher’s signature next to your notes.)

“The instruments (pieces) of a satellite not only have different jobs, but they weigh different amounts too. After deciding on the type of satellite, your team will design the satellite using Legos. “

Rules (Part 1): Refer to the Satellite Instrument Data Table. This sheet will guide you on what the different instruments are called, what they do, how much they weigh, and how much power they require.

Your team’s satellite can have . . .
a.) no more than 4 instruments.
b.) be able to fit inside the space capsule.
c.) AND once assembled, the satellite must weigh between 15-21 grams.

“You will each record the instruments you intend to use to build the satellite, include the weight of each piece, and once you pick up the pieces, sketch two views of your constructed satellite (refer to the sheet provided to you). You can weigh pieces individually. You are not allowed to assemble the satellite until after your sketches have been approved by a teacher.”

Rules (Part 2): After sketches have been approved, you will use gloves to assemble your satellite. This represents how astronauts fix and operate on satellites while in space. Each teammate will have a turn at assembly or reassembling the satellite. Weigh the satellite and compare it to your recorded data.

Rules (Part 3): Shake Test. Place your satellite inside the space capsule (Styrofoam cups) and shake the capsule rapidly for 30 seconds. Take the satellite out of the capsule and see if your satellite made it in one piece.  If not this is the time to modify your satellite and retest.

Shake Test

*If time permits, review another team’s design and complete the steps on the Quality Assurance Form.

We finish off like most activities, where student feedback is key.

  • What did you like or dislike about this activity?
    • Explain why.
  • How would you change this activity to make it better?
  • What is something you wish you could have done?

Our school year took a restart after Hurricane Florence, with some of the kids living in different places or with many members, to transfers of familiar faces moving and new faces joining.  Here’s to new beginnings.

 

STEM activities to get push pause on the stress, and puzzle our minds:

  • Coding mazes with Bee Bots.
  • Exploring how a statue’s shadow moves.
  • Building hats to protect our ears and eyes from the sun.
  • Solving the Hanoi Tower Challenge.
  • Building bridges to cross.
  • Using the power of air with a Vortex Cannon.
  • Rescuing one from a well, constructing a claw.

We’ll soon be back with full reports of the tinkerers and thinkerers.  Keep an eye and ear out for our multipurpose marine tank.

Back In The Saddle

1s & 5s

A bit lazy on the title I know, but I’m running out of STEAM.  Get it!?  (cue crickets chirping)   Eh . . .  anyway . . . let’s take a gander at first graders who continue applying their know-how about forces, pushes, and pulls. This lesson centered on pulls with the use of weight and gravity; much like what pulls glaciers if we recount to the last post with 4th grade’s topic.  These first graders tinkered with adding and/or subtracting the amount of washers to their vehicle by connecting them via string & paperclips.  After exploration time with the vehicles and the weights, the students repeated the activity beginning with one washer, then 2, 4, 6, and 8 writing down observations between each trial as to which provided the greatest/fastest pull, and why they believed this to be true.  We’ll pick up with this activity and review our discoveries in the next post.

Weight & Gravity

 

Moving on to 5th where our marine biologists are using bathymetric sonar technology to map the ocean floor.  NOAA’s ship, the Okeanos Explorer, uses this type of sonar which flares out onto the ocean bottom, pinging data back to the ship in a color coded scale to outline trenches, volcanoes, sunken ships, etc.  These students constructed models of the abyss and/or trenches which they are preparing for another class.  Pictures of them sampling data by use of color coded straws are models built by another 5th grade class.  The lower the straw, the deeper the coordinate.  After recording the data the next step will be to transfer the information to a color bar graph, one sheet per column (columns were from A-J).  After the bar graphs are made for each column the students will cut, and glue the data in their journals to create a three dimensional pop-up scale.  We will have pictures once this is complete, so stay tuned and until then check out the pictures and video.

Properties of Gases and Liquids

Let’s check in on 3rd and 4th graders as they tie in the basic properties of matter in the STEAM lab:

4th graders simulated the movement of glaciers across Earth’s surface using ice/sand cubes to scratch across trays covered in aluminum foil, noting how these massive natural phenomenons create valleys, mountains, and leave behind rock debris known as glacial till or moraine.  After the hands-on activity we followed up with a minds-on digital breakout about  . . . you guessed it, glaciers.  If you’ve never completed or seen one of these, it is a series of questions to unlock to proceed to the next question.  These questions include directions, vocabulary, numbers, etc.

Glacier Digital Breakout

3rd graders are investigating how air takes up space by first attempting to inflate a balloon into a bottle.  After several attempts and becoming light headed the kiddos realized that the air trapped in the bottle prevented the inflation of the balloon.  Thus, oxygen takes up space.  Poking a hole into the bottle gave students the ability to inflate the balloon by blowing the air in the bottle out, yet once they ceased inflating the balloon, the air was sucked back in taking up the space it once did.  After paired discussions, many students came to the conclusion that a second property of air is that although we cannot see oxygen we can see it when it moves something.  An air bazooka was used to model this theory by knocking over Styrofoam cups.  Challenge 1: Students built teams of three to design an air powered vehicle.  They discussed the variables teams wanted to use (long thin balloons or round, fishing line or kite string, a whole, 3/4, 1.2, or 1/4 straw).  Stipulation: The air vehicle must travel 5 yards.  Students tested their designs three times, keeping track of the distance and time it took to travel.

Air Engineering

To expound on the idea of air taking up space, students performed an activity called Protect The Tissue, where a napkin or tissue is placed in the bottom of a plastic cup, tipped upside down and submerged into a bucket of water.  This demo allows students to see how air is trapped inside the cup, serving as a barrier between the water and the tissue.  We discussed how this might be helpful for people in real life.  Their brainstorming led to SCUBA diving, and submarines.  So the challenge is now to apply their knowledge properties of matter in creating a submarine.  After researching the term buoyancy, teams problem-solved to devise a submarine (plastic bottle) to float on the surface of water in a tub.  Then they had to figure out how to make the sub sink to the bottom of the tub.  After achieving these two stipulations teams worked on reaching a neutral buoyancy.  Material for this activity are a plastic bottle, cap, water, bubble packing wrap, and rubber bands.  We are still testing the subs, so content will be added after the naval fleet has accomplished their mission.  Until next time.

Updates on project #FullSTEAMAhead

After painting the ceiling tiles to match the periodic table, local artist Eve is adding murals to the room.  This renovation process would not have been possible without being a recipient from Lowe’s Home Improvement’s Toolbox for Education grant.  Below is a replica of our local estuary in the Bogue Sound.  Eve is working on the engineering process and will then add a mural of the phases of the moon as well as NC’s watersheds.  Who knows what else I can con her into doing for us before she’s had enough of me?

You’ll also notice our outreach partner from the community college Aqua Culture Department (located in MHC) measuring dimensions for the touch tank.  I was fortunate to receive grant funding from both the Carteret-Craven Electric Co-op ($1,000) and the Mid Atlantic Marine Education Association ($1,000) to begin this project.  David Cerino (from the college) will aid in constructing the tank and supplying the water as well as critters (on loan) for our students to observe, care for, and learn from.  The tank will serve multiple purposes.  We will convert it as needed (which basically means adding or removing life) for use in water quality testing, observing oyster filtration rates, replicating our estuary ecosystem, understanding detritus (bottom) feeders, sea level rise with focus on the moon and how it affects the tide, wave energy (harnessing renewable resources), engineering water crafts, testing buoyancy, and whatever else I can think of.  We hope to finish the tank by February ’18.

 

Speaking of outreach, our friend Sarah from NOAA (National Oceanic & Atmospheric Admin.) dedicated her day to working with 5th grade and touching on many of their content strands:

5.P.2.1 Explain how the sun’s energy impacts the processes of the water cycle (including, evaporation, transpiration, condensation, precipitation and runoff).

5.E.1 Understand weather patterns and phenomena, making connections to the weather in a particular place and
time.
5.E.1.1 Compare seasonal changes in weather conditions (including wind speed and direction, precipitation, and temperature) and patterns.
5.E.1.2 Predict upcoming weather events from weather data collected through observation and measurements.

Her activities included making a model of a home on the shore and viewing the affects of the tides as glaciers melt, and then observing what happens to the water level in a bottle as heat is applied.  The kids made predictions, measured the increase of the water as it crept up the straw, and kept record of the process.

Below also includes 5th graders exploring water convection currents (how waves form from hot pockets of water mixing with cooler ones).  To see video footage check out the twitter page (tweet from 1/11/18) on the right of the blog.

Third graders devoted a unit to the structure and function of the human body. 3.L.1.1 Compare the different functions of the skeletal and muscular system.  They manipulated leg models as read in the last post, but also explored a model hand (glove filled with sand) to determine what might be missing.  As they made comparisons to the model hand and their own, they were daunted the task of creating a mechanical hand which would be able to

a.) move it’s phalanges

b.) grasp an object

c.) pick that object up without dropping it

Partners developed designs with the given materials in mind to make their project a success on any or all of the three levels mentioned.

And we also have footage of first graders operating our newly acquired Bee Bots (again thank you to CC Electric Co-op for another $1,000 grant) to use with their knowledge of push and pull forces.  First grade was given challenges of moving boxes out of the way by coding the robots to either push or pull the boxes (rope included) according to the placement of the Bee Bot.

 

Before this post ends, I shamelessly ask any one reader of this post to spread the word via social media, letter, or pigeon carrier about our next need.  In the words of Colt Cabana, Facebook it out, snap chat it out, tweet it, vine . .  wait is this is even a thing anymore?  Anyway – I have written a piece through Donor’s Choose to fund us for two class sets (18) of Vernier Go!Motion Devices which will contribute to all grade levels in our school.  To read about our want, click on the link Echo Echolocation to read how these devices will be used with the students chrome books to conduct more hands-on activities relating to forces and motion, marine sciences, and engineering to name a few.  Our date to qualify is expiring in February.  We currently have $100 donated to the cause.  I’m not asking that you yourself pay, but maybe know of someone with means that could help.  Bluntly, I a need a cup of sugar.  Do you know a Sugar Daddy?

Thanks for reading.
