Students at Poquoson Elemen-
tary and Poquoson Middle
School are monitoring their
own vegetables. Students are
in charge of watering and
maintaining a variety of lettuce
and other delicious salad in-
gredients. Stay tuned to see
how they grow!
Poquoson Elementary Third
graders entered the mobile
planetarium on February 16th
to explore what might have
killed the dinosaurs. Fourth
graders learned about the Milky
Way, and fifth graders discov-
ered how the conditions of
Earth and space contributed to
the sinking of the Titanic.

STEM Update
Dome Theater Brings Planetarium Experience to
Poquoson Elementary Students
Teacher STEM Challenge
Mr. Fry and Mrs. Bowden from Poquoson High School
and Mrs. Ward from Poquoson Middle School go
through the Engineering Design Process to develop an
amusement park ride that prevents people (ping-pong
balls) from falling out.
Water Walking
Materials:
Clear cups
Food coloring
Water
Paper towels
Small bin turned over
Directions:
Set two cups on top of the bin
Set two cups on the table surface next
to the bin
Add food coloring to the cups on the
bin (try a different color for each
cup)
Fill the cups with the food coloring up
almost to the top with water
Take a strip of paper towel and con-
nect it from a food coloring cup to
an empty cup; do the same for
the other two cups.
Try making the two food coloring cups go
into one cup to make a new color.
Design a Keep-a-Cube Container
Materials:
2 ice cubes
A small box (shoe boxes work well)
Waxed paper
Masking tape
Newspaper
Aluminum foil
Rubber bands
Paper plate or plastic bowl
Directions:
Using the materials, create a container
that can keep an ice cube from
melting.
When the container is complete, put
one ice cube inside and one on
the plate/bowl.
Compare each ice cube after 30
minutes.
Compare the melt rate using other materi-
als such as cotton balls, foam peanuts,
different size boxes, etc.
Do It Yourself STEM Activities Crystal Names
Materials:
Pipe cleaners
Fishing line {twine or yarn will work
too}
Pencils or wooden skewers
Scissors
Glasses or plastic container {one for
each color}
A container large enough to hold your
name {if doing your name as a
single piece written in cursive}
Borax
Food Coloring {optional, if you want
colored letters you can dye the
borax solution or use colored pipe
cleaners}
Liquid measuring cup
Tablespoon
Heat Safe Mixing Bowl
Directions:
Write your name with the pipe cleaners
(try to keep the letters connected,
try cursive) or make a design with
the pipe cleaners
Make sure your name or design will fit
in your container without touching
the sides of the container
Use the fishing line or twine or yarn to
suspend your name or design a
few inches from the wooden
skewer or pencil
Have an adult heat up a large pot of
water. Mix 3 tablespoons of borax
per cup of hot water. Add food
coloring (you can have multiple
containers to make multiple col-
ors if you have separate letters or
separate designs).
Carefully lower each letter into the
colored water.
Can Telephones Materials:
Recycled Soup Cans Duct Tape (optional) String of varying sizes and thick-
nesses Toothpicks or Paperclips
Directions:
Wrap your clean cans with duct tape.
Have an adult cut a hole in the center of the bottom of the can.
Tie the string of your choice to a toothpick or paperclip.
Thread the string through both holes in the cans.
Test out different lengths and thick-nesses to see which carries sound bet-ter.
Build a 3D Structure Materials:
Pipe cleaners and straws or mini marshmallows and toothpicks (or uncooked spaghetti)
Directions:
Thread the pipe cleaners through straws; straws can be cut with scissors to make various lengths.
Connect pipe cleaners to make a 3D Structure
Or Insert a toothpick (or uncooked
spaghetti) into a mini marsh-mallow
Continue to connect them to make a 3D Structure
How tall can you make it? What shapes can you make?
Buoyancy Experiments Materials:
12”x12” foil square Coins or small pebbles
Directions: Form the foil into a boat See how many coins or pebbles it
can hold while floating in wa-ter.
Experiment with different boat designs to see which holds the most weight.
