At the Mary McDowell Center for Learning science is defined as
the process of investigating the natural and built world in order
to understand it. We recognize that all children naturally attempt
to make sense of the world around them through observing, questioning,
hypothesizing, and experimenting. The purpose of the science program
is to support children in this endeavor and help them make sense
of what they see and experience. Through our science program, we
hope to foster childrens interest in and awareness of the
world around them, broaden their knowledge and deepen their understanding
of it, and strengthen their ability to investigate it. While developing
their science skills, the science program enables children to actively
construct their scientific knowledge through guided discovery. The
programs goals, content, and methodology are all aligned with
the National Science Education Standards.
At the Center children attend science as a whole class two times
per week for 45-minute sessions. Science classes are held in a separate
classroom where a variety of science-related materials are always
on hand. In addition, classes make use of other places in the school,
the neighborhood, and the city as necessary to the study of a particular
curricular area.
Goals
- Understanding of the natural and built world.
- Understanding of key scientific concepts and principles.
- Ability to use scientific processes.
- Awareness of the local environment and natural phenomena.
- Knowledge of other environments with distinct natural phenomena.
- Interest in pursuing scientific questions.
- Experience with technological design.
- Understanding of science as a dynamic discipline in which the
quest for knowledge is on-going.
Concepts
Concepts are ideas or principles that underlie and connect all
areas of scientific study. Concepts provide a framework for thinking
about and understanding any topic in science. Essential concepts
for students are:
- systems, order, and organization
- evidence, models, and explanation
- constancy, change, and measurement
- evolution and equilibrium
- form and function
Content
Traditionally, science is divided into three discipline areas:
physical science, earth and space science, and life science. In
addition to these, and to the unifying concepts described above,
there are four other important content areas in science. These are:
science as inquiry, science and technology, science in personal
and social perspectives (including environmental issues), and the
history and nature of science (which focuses on science as a human
endeavor). At the Center, three science units are usually taught
each year, one in each of the three disciplines. The other content
areas are then woven into one or more of those units. The chart
below shows how this works one example is given per content
area.

Unifying Concepts
Ex: Constancy, change, and measurement
|
The form energy takes can be changed, but the total
amount of energy remains constant.
|
Changes in the angle that sunlight hits the earth as
it revolves around the sun causes seasonal changes in
a predictable pattern.
|
A decrease in the amount of sunlight reaching the earth
causes some trees to lose their leaves, since the function
of leaves is to convert the light energy from the sun
into food.
|
|
Physical Science
|
Electrical circuits require a complete loop through
which an electrical current can pass.
|
|
|
|
Earth and Space Science
|
|
The earth rotates on its axis as it revolves around
the sun, causing day and night and seasonal changes.
|
|
|
Life Science
|
|
|
Trees, like all plants, have life cycles. They begin
as a seed, grow, produce more seeds, and eventually
die.
|
|
Science as Inquiry
|
Students explore how the brightness of a light bulb
is affected when additional batteries are added to a
circuit.
|
Students track the phases and rising/setting times
of the moon and search for patterns in their data.
|
Students observe and record the changes in a tree over
time through observational drawings.
|
|
Science and Technology
|
Students figure out how to make a flashlight.
|
Students use a compass to find out the direction of
the sunrise.
|
Students make recycled paper.
|
|
Science in Personal and Social Perspectives
|
Electric power must be converted from another energy
source, which can have environmental consequences. Conserving
electricity helps preserve the environment.
|
Not applicable.
|
People can use trees to meet their needs, e.g. for
fuel, housing, or paper. But people also need standing
trees to prevent mud-slides and erosion, and for absorbing
CO2 in the air.
|
|
History and Nature of Science
(Science as a Human Endeavor)
|
The ability to harness electricity is a relatively
recent discovery in science. Thomas Edison a
person with learning disabilities invented the
light bulb.
|
Our understanding of the universe has progressed over
time (Copernican vs. Galilean models). All kinds of
people become astronomers, e.g. Maria Mitchell, or Benjamin
Banneker.
|
The study of trees is a very new field in science.
An interview with an arborist introduces students to
this field and possible career.

Curriculum Topics
Curriculum is the vehicle for learning the content. While some
topics are developmentally specific, most can be adapted for any
age level. Therefore it is possible for seven-year-olds to study
the same topic as ten-year-olds, but the content learned could be
very different. As a result, students may return to a topic in science
class that they studied years before, this time drawing on their
prior knowledge but delving much deeper into the subject matter.
Conversely, it is possible for children to learn the same content
through different topics. For example, the transfer of energy through
food webs could be taught through any ecosystem study (such as wetlands)
or through an animal study (such as birds of prey).
A number of things are taken into consideration when choosing a
curriculum. When possible, topics are chosen that overlap with what
students are studying Social Studies, as this enhances childrens
understanding in both areas. Because first-hand experiences greatly
enrich students learning, consideration is also given to the
environment of New York City and the resources available here.
The chart below gives examples of topics that might be taught at
different age levels at the Center.

Process Skills
It is equally important for children to learn scientific approaches
to investigating their world as it is for them to learn science
content. This enables children to pursue their own questions independently
and prepares them for advanced scientific study. Since many of these
skills are things that children do naturally, the goal is to develop
childrens abilities in these areas. Most of the skills involve
specific areas of language so support childrens overall language
development as well. Essential science process skills include:
|
Questioning
|
Hypothesizing
|
Predicting
|
|
Fair Testing
|
Drawing conclusions
|
Reporting

Materials
The list of materials used in science is endless. Each curricular
area involves materials that are particular to it, and many curriculums
also make frequent use of everyday materials such as straws, cans,
or food coloring, that are too numerous to mention. The list below,
therefore, is designed to give an idea of the range of materials
used in science. In addition to the classroom materials, materials
are sometimes brought in on a temporary basis. The Brooklyn Childrens
Museum, for example, loans out "portable museum kits."
Kits borrowed in the past include: fossils, human bones, and African
instruments. Students themselves also frequently bring in objects
or books related to the field of study.

Assessment
Students are evaluated on their understanding of the content covered,
their use of science process skills, their approach to learning,
and their classroom skills.
Students progress is assessed through a variety of means,
including:
- Participation in discussions and activities
- Observational drawings and descriptions
- Projects
- Written assessments
- Portfolios
