Homeschooling science made easy.

GENERAL SCIENCE

Mix baking soda and vinegar.  Observe.

EARTH SCIENCE

Sculpt a shield volcano out of modeling clay.  In crater, mix baking soda and vinegar.  Observe.

CHEMISTRY

Wearing safety goggles, add 1 mole sodium bicarbonate to 1 liter of a  five percent (by volume) solution of acetic acid.  Observe.

METALLURGY

Obtain a silver spoon, a stainless steel spoon, and an aluminum spoon.  Use each spoon to mix baking soda and vinegar.  Observe.

PSYCHOLOGY

Obtain an eight-ounce drinking glass.  Add one-quarter cup of vinegar and one-quarter cup of a solution of baking soda and water.  Is the glass half empty or half full?

PHYSICS

From atop the Leaning Tower of Pisa, let fall simultaneously a three-pound box of baking soda and a one-quart bottle of vinegar.  Observe.

THEORETICAL PHYSICS

Consider a box of baking soda and a bottle of vinegar located in a spacious chest or elevator in empty space, far from appreciable masses.   A rope is attached to the center of the lid of the chest, and an external being pulls on the rope, accelerating the chest upwards.  In the frame of reference of the vinegar and baking soda, how does this compare to remaining at rest in a gravitational field due to a massive body such as the earth?

ECONOMICS

If the demand for baking soda rises, what will happen to the supply of vinegar?  Explain.

MEDICAL RESEARCH

Add 1/2 teaspoon baking soda to 4 fl. oz. of water in one glass. Add 1/2 teaspoon vinegar to 4 fl. oz. of water in another glass.  Dissolve completely in water.  (Accurately measure 1/2 teaspoon.)   Give one glass to each of two research subjects complaining of sour-tummy every 2 hours.  Observe. 

CIVIL ENGINEERING

Build a balsa-wood model bridge capable of supporting a paper sack containing 200 grams of baking soda across the open span of a five-gallon bucket full of vinegar. Add baking soda, 100 grams at a time, until the bridge fails.  Observe.

HOME ECONOMICS

       1/2 c baking soda (packed)
       1 c vinegar
       1 tsp vanilla

       Preheat oven to 350 degrees.  Combine vinegar and vanilla in a two-cup liquid measure.  Whisk baking soda in a medium bowl.  While continuously whisking, slowly add vinegar mixture in a thin stream.  Observe.

ENTOMOLOGY

Design an experiment to answer the following question:  Can you catch more specimens of Drosophila melanogaster with baking soda or with vinegar?

MILITARY SCIENCE

Construct a trebuchet capable of lobbing vinegar-filled latex balloons over the battlements of the enemy’s strategic stockpile of baking soda.  Fire when ready.
