June/July 2014 5

The enthusiasm for science displayed by

students in early elementary grades is

unparalleled They’re eager to learn,

engage, and investigate They’re

moti-vated by their insatiable curiosity

And the earlier children are engaged in

science, the better Studies have shown

that early interest in science needs to be

ignited before middle school and is

instru-mental in motivating students to pursue

a career in science If not nurtured in

ele-mentary school, the spark for learning

sci-ence diminishes (Maltese and Tai, 2010)

Unfortunately, the amount of time

spent on science in Grades 1–4 has

steadi-ly declined since the passage of the No

Child Left Behind Act of 2001 Teachers

are spending an average of 2.3 hours per

week on science, compared with weekly

es-timates of 11.7 hours on English language arts and 5.6 hours on mathematics (Blank, 2012) However, the effects of quality sci-ence instruction in the elementary grades can be far reaching In 2012, the National Research Council cautioned that omit-ting science at any grade level potentially impacts student conceptual learning and places additional demands on teachers in higher grades

To address these concerns, I

participat-ed in a Jacob K Javits Giftparticipat-ed and Talentparticipat-ed Students Education program project (Uni-versity of Arkansas at Little Rock: STEM Starters) STEM Starters was developed

to target science learning in elementary grades (Cotabish, Dailey, Robinson, &

Hughes, 2013; Robinson, Dailey, Hughes,

& Cotabish, accepted)

Over a two-year period, STEM Starters provided 30 teachers with 120 hours of pro-fessional development focused on science content and inquiry-based instructional practices Additionally, STEM Starters used

a peer coach to assist teachers with imple-menting problem-based science curricula

in both regular and gifted classrooms After participation in STEM Starters, both teach-ers and students demonstrated improved science learning (Robinson, Dailey, Co-tabish, Hughes, & Hall, accepted)

As a member of the STEM Starters program, I served as a peer coach to 30 elementary teachers During this time

I often visited classrooms and provided instructional assistance to the teachers Students eagerly awaited my arrival and would clap and cheer when I entered the

“Think Like Scientists”

Gifted kids thrive when solving problems that are relevant to their own lives (Rogers, 2002) When kids are encouraged to “think like scientists” and engage in the practices of real science, they make some amazing connections

For example, during my work with STEM Starters, I helped 2nd grade students investigate weather

Students set up an authentic weather station where they monitored the daily weather and made predictions about future weather conditions As part of a culminating activity, students pretended to be weather

forecasters and delivered the forecast to their peers

A short time later, I received a follow-up text from one of the teachers She said that students from her

class approached her during recess and alerted her to the fact that the weather was changing They

explained that the air was very heavy so the humidity must be high They predicted that a low front was

approaching The most exciting thing about this scenario was the fact that students were relating their

science learning to real-life situations They were able to take their knowledge out of the context of the

classroom and put it in the real world

As parents and caregivers of gifted children, it’s important to always be on the lookout for ways to provide authentic, real-life, real-world learning experiences to ignite the young gifted mind

room Once, I overheard a child say, “Yay!

Our scientist is here!” They were excited

about the opportunities to actually “do”

science We conducted experiments and

even set up a working weather station (see

sidebar “Think Like Scientists” on page 5)

However, programs such as STEM

Start-ers are not options for most schools and

many students don’t often have

opportu-nities to cultivate their interest in science

during their school day (Banilower, Smith,

Pasley, & Weiss, 2006) Parents, too, can

help foster a love for science by encouraging

children to question, explore, and

investi-gate They can promote students’ curiosity

and provide multiple learning opportunities

by volunteering to lead simple experiments

as a classroom guest speaker; enriching their

child’s science learning through after school programs or summer camps; or simply using household supplies to conduct experiments

at home

Science also doesn’t have to be expensive

or be in the context of a costly kit

Heilbronner (2013) encourages parents

to provide opportunities for children to conduct scientific investigations and to explore through “science safaris,” where students investigate things in their own surroundings, whether it be at local museums or the nearby woods

STEM Starters also created a take-home activity booklet to assist parents in provid-ing science investigative opportunities for their children The booklet contains famil-iar, easy-to-do activities that uses

inexpen-sive materials found in most households

By doing these activities, I hope students are encouraged to question more and seek investigations beyond the prescribed activ-ity to spark their love of science

ele-Experiment 2

Title: Musical Rulers Problem: What causes sound to change?

Hypothesis: Increasing or decreasing the length of a ruler that

hangs off a table affects the sound made.

Materials: plastic ruler Procedure:

1 Place the ruler on the edge of a table so that half of it hangs off of the table.

2 Hold the end of the ruler flat against the table with one hand With the other hand, lightly snap the end of the ruler that hangs off the table Listen to the sound.

3 Push the ruler back, so that less of the ruler hangs off the table Repeat step two and listen to the sound.

4 Push the ruler so that most of it hangs off the table Repeat step 2 and listen to the sound.

Results:

Shorter

Longer

Conclusion: What caused the sound to change when the length of

the ruler was altered?

Experiment 1

Title: Hydrophobic Pepper Problem: How does soap act in the

presence of pepper and water?

Hypothesis: Adding soap to a container

of water and pepper causes the pepper

to react.

Materials: cup, water, pepper, liquid

soap, eyedropper

Procedure:

1 Fill a cup half full of water.

2 Sprinkle pepper on the water’s surface and observe what the pepper does.

3 Add a drop of soap to the middle of the water and observe.

Conclusion: What happened to the

pepper? Draw a picture of what the pepper looks like Why do you think this happened?

Experiment 3

Title: Raining Meteorites

Problem: Where can we find meteorites?

Hypothesis: Meteorites can be found in our own backyards.

Materials: paper cup, pencil, string, magnet

Procedure:

1 Poke three holes into the cup just below the rim.

2 Thread the string through each hole, leaving the string

long enough to reach from a child’s hand to the floor.

3 Tie knots to hold the strings in the cup, then pull the

strings above the cup and tie.

4 Place a magnet in the cup.

5 Take the meteorite finder outside and walk on the

side-walk holding the meteorite finder just above the ground.

6 Listen for small clinks.

7 Pieces of rock that the magnet attracts might be meteorites.

These rocks contain iron and nickel just like meteorites.

Conclusion: Describe what you found How do meteorites

get in our yard?

What is a Javits Grant?

The Jacob Javits Gifted and Talented Students Education Act (Javits) was originally passed by Congress in 1988 as part of the Elementary and Secondary Education Act to support the development

of talent in U.S schools The Jacob K Javits Gifted and Talented Education program is the only federal program that specifically addresses the needs of gifted and talented children, by offering competitive and discretionary grant funds for those expanding research, strategies, and activities for gifted and talented children The Javits Act does not fund local gifted education programs The purpose of the program is to orchestrate a coordinated program of scientifically based research, demonstration projects, innovative strategies, and similar activities that build and enhance the ability

of elementary and secondary schools to meet the special educational needs of gifted and talented students, especially those who are traditionally underrepresented in gifted programs Javits grants are managed through the U.S Department of Education

From 2011 to 2013, the Javits Act was not funded In 2013, however, the Javits Act received

$5 million for fiscal year 2014 Parents and educators should communicate with their senators and

representatives to encourage continued Javits funding Go to www.n agc.org for more information.
