GREEN and SUSTAINABLE Science Fair Projects

This year all our Science Fair Projects will be GREEN and SUSTAINABLE


The following videos offer an overview on how to conduct an investigation:








What type of investigation will you be conducting for your Science Fair Project? Explain

8th grade Heredity: Investigating Human Traits

How much variation is shown by the students in our class?

In class we looked at six different human characteristics-eye color, tongue rolling, finger crossing, PTC tasting, height and arm span-in oder to study human variation.

finger crossing

measuring arm span using a meter stick

measuring height

PTC tasting

sharing data

recording data

If a trait is not inherited, what else might cause it? Explain

7th grade Geology: Landforms

Identify the following landforms:

A.
B.

C.

D.

E.

F.

How do different landforms affect the economic development of a community?

Buliding our own ocean: Investigating currents and circulation

Does salt water float or sink?

Does cold water float or sink?

Water density is important for ocean circulation because dense water sinks.

Where is the Gulf Stream?
How does wind influence surface currents across the globe?

SUPER SLIMEY POLYMERS


What is a polymer? and How can we change the properties of a polymer?

Materials: glue, borax, and water

ICKY......

CHEMISTRY DEMONSTRATION

Polyurethane foam

Elephants' Toothpaste (hydrogen peroxide + potassium iodide + dish soap)

Chemiluminescient: hydrogen peroxide + chlorine

Magnesium buring in dry ice (carbon dioxide)

This energic reaction produces magnesium oxide and elemental carbon

PHYSICS DEMONSTRATION

50 pound pendulum

Air hose and ping-pong ball

Rotating Platform: inertia

Electricity

Hot and cold

Heating an object causes it to expand

Cooling an object causes it to contract

How many balloons can we fit in the bucket?

14 balloons!!!!

Bridge to Candybithia

Ojective: design and build a bridge using marshmallows and toothpicks that will be tested for the amount of weight it can support.

Beam, arch, or suspension bridge?

Which bridge was the strongest?

Mealworm Madness!!

Mealworm locomotion.

What type of surface will a mealworm prefer? sandpaper or cardboard?

What is a mealworm's habitat preference? light or dark areas?

Columbia University's Morningside Campus

Chemistry Buliding


Around campus......

Rose frozen in liquid nitrogen

Hydrogen gas is highly flammable!!!

Bottle Rocket Science

The amount of energy in a Gummy Bear!

Converting bond energy from a glucose molecule to heat/light energy using a Gummy Bear.
