A Natural Approach to Chemistry
The
central premise of A Natural Approach To Chemistry (NAC) is that chemistry is all around each of us,
every day. Chemistry is us. We eat chemistry. We drink chemistry. Chemistry is the complex choreography
of atoms and molecules that sustains life. Chemistry also shows us the details in the non-living world.
Chemistry is both how we create the materials of human technology, and also how the natural world builds
and renews itself.... |

EarthandYou™
Created by the American Geological Institute, the voice of the geoscience community, this DVD-based
package is an amazing resource for elementary school Earth System Science... |
 |
Investigating The Design & Output of Wet Cell Batteries
This kit introduces students to the concept of energy conversion through the study of a simple
electrochemical cell connected to an electric motor... |
 |
Density: Layers of Liquids
This activity
provides students with experiences that allow them to develop an operational definition of density.
Students are provided with liquids of different viscosity and density and asked to observe and predict,
based on their observations, the relative density of each... |
 |
Investigating Hydrogen Fuel Cells
This
module focuses on hydrogen fuel cell technology as one potential solution to energy concerns. Students
first consider some tradeoffs of using various fuels, including hydrogen, for powering vehicles then use
an electrolyzer to produce hydrogen and oxygen gas from water... |
 |
Elements and The Periodic Table
This kit
contains two activities. In Activity 1, students compare preselected data on physical and chemical
properties of 14 elements and sort the elements into groups based on common properties. Then they
compare their classifications with groups – or families – of elements as defined by scientists... |
 |
Modeling Chemical Equilibrium
Students use
an innovative LAB-AIDS® model to simulate the simultaneous occurrence of forward and reverse reactions
that helps develop the concept of chemical equilibrium and the equilibrium constant (Keq)... |
 |
Contaminants and The Water Cycle
In this
modeling activity, students follow a molecule of water as it
travels through the water cycle. The
activity can be used to model
both the basic water cycle and the water cycle with biological and
chemical contaminants that are picked up along the way... |
 |
Energy Transfer: Waves, Sound and Light
In
this series of activities students produce both longitudinal and
transverse mechanical waves and
compare their similarities and
differences... |
 |
Converting Gravitational Potential Energy to Kinetic Energy
This kit introduces students to the concepts of kinetic and
gravitational potential energy and the
conversion of one form
of energy into another. Students design and conduct an experiment to
quantitatively test how the variables of mass and height affect the energy carried by a metal
cylinder... |
 |
Energy Transfer: Motors, Generators and Sources of Electricity
Students explore the relationship between, and practical applications of, electricity and magnets. They
use a battery, a magnet and a coiled wire to build a simple electric motor and then use a pre-assembled
electric motor to generate electric current... |
 |
Investigating Photovoltaic Cells
Students
use photovoltaic cells to transform energy from sunlight into electrical energy as they investigate
solar energy as an example of a renewable energy source. They explore how to power a motor using the
photovoltaic cells and investigate some factors that affect the cells’ ability to transform light energy
into electricity. They then discuss the advantages and disadvantages of using solar energy... |
 |
Using Remote Sensing to Determine Topography
Students are introduced to remote sensing through a hands-on activity that allows them to collect data
about concealed landforms then use it to create visualizations of the landforms... |
 |
Weather Forecasting
Students work
together in teams to interpret weather maps from eight consecutive days. Each team initially interprets
the map for a single day and constructs a weather report for that day. Teams assigned the same day then
combine to prepare, and present their weather report to the class... |
 |
Photosynthesis, Plants and Food
In the
opening activity, student teams use LAB-AIDS® atom models to build carbon dioxide and water molecules
then “react” them to form sugar and oxygen molecules... |
 |
Investigating Selective Breeding
In this
series of two activities students explore inherited traits. They use LAB-AIDS simulated corn ears and
Punnett squares to gather data on, interpret, and predict the probability of traits being passed from
parent to offspring... |
