A
SCIENTIST
A scientist is very curious.
A scientist
asks many questions and then tries to learn the answers by experimenting.
First, a scientist predicts what he thinks will happen.
Next, a scientist
makes a guess to explain how what he has predicted will happen.
A scientist
tries his ideas.
By observing and measuring carefully, a scientist collects
information.
A scientist must record all information carefully in an organized
way.
A scientist then must draw a conclusion from what has happened by comparing
and contrasting the information he has recorded.
Finally, a scientist writes
a report about his findings so that others may learn from his experiments.

Bad Science
Preamble
This page is maintained by Alistair B. Fraser in an attempt
to sensitize
teachers and students to examples of the bad science
often taught in schools,
universities, and offered in popular articles
and even textbooks.

Try
to be VERY clear when presenting information!
Kids interpret things in their
own manner!
5th and 6th grade responses to science
questions on tests:
*There
are 26 vitamins in all, but some of the letters are yet to be discovered.
*
Genetics explains why you look like your father, and if you don't, why you should.
*Vacuums are nothings. We only mention them to let them know we know they're
there.
*The cause of perfume disappearing is evaporation. Evaporation gets
blamed for a lot of things people forget to put the top on.
*Water vapor
gets together in a cloud. When it is big enough to be called a drop, it does.
*Mushrooms always grow in damp places, which is why they look like umbrellas.
*Momentum is something you give a person when they go away.
*A monsoon is
a French gentleman.
*To keep milk from turning sour, keep it in the cow.
*When
planets run around and around in circles, we say they are orbiting. When people
do it, we say they are crazy.
*For asphyxiation, apply artificial respiration
until the patient is dead.
*Thunder is a rich source of loudness.
*One
of the main causes of dust is janitors.

A
whole new way to use sandwich bags!
You will need:
One small zip-lock
bag - small freezer bags work best.
Baking soda
Warm water
Vinegar
Measuring cup
A tissue
What to do:
1. Go outside - or at least
do this in the kitchen sink.
2. Put 1/4 cup of pretty warm water into the
bag.
3. Add 1/2 cup of vinegar to the water in the bag.
3. Put 3 teaspoons
of baking soda into the middle of the tissue
4. Wrap the the baking soda up
in the tissue by folding the tissue around it.
5. You will have to work fast
now - partially zip the bag closed but leave enough space to add the baking soda
packet. Put the tissue with the baking soda into the bag and quickly zip the bag
completely closed.
6. Put the bag in the sink or down on the ground (outside)
and step back. The bag will start to expand, and expand, and if all goes well...POP!
Cool huh? Nothing like a little chemistry to to add fun to a boring afternoon.
What happens inside the bag is actually pretty interesting - the baking soda and
the vinegar eventually mix (the tissue buys you some time to zip the bag shut)
When they do mix, you create an ACID-BASE reaction and the two chemicals work
together to create a gas, (carbon dioxide - the stuff we breathe out) well it
turns out gasses need a lot of room and the carbon dioxide starts to fill the
bag, and keeps filling the bag until the bag can no longer hold it any more and,
POP!
Be sure to clean up well and recycle those plastic bags...have fun!
