Click on a tab to view a listing of all the TryScience activities by type, topic, or age group, or to search the world of science centers.
|
The search engine on TryScience.org searches the websites of hundreds of
science centers around the world for you! One of them surely has what you
are looking for. Enter your query into the search box at the bottom of all
TryScience.org pages.
Didn't find what you wanted? Found too much? Try
narrowing your search:
-
Use quotation marks to group several words
into a phrase. Example: Canada "science center" finds documents
that contain either the phrase "science center" or the word
Canada.
-
To get the most relevant documents at the top
of the list, enter several synonyms for the topic. Example: space
rockets probes instead of just one of those words increases the
chance of finding documents about rockets.
-
Use a "Boolean" query by putting AND, OR, AND
NOT, NEAR between your keywords. AND, OR, AND NOT do what they
imply: Example: experiment AND biology will return listings with
both keywords, whereas experiment AND NOT biology will return all
experiment listings but no biology (and no biology experiment).
Using NEAR between keywords will literally search for those
keywords near one another.
-
A plus sign (+) in front of a word means that
word must be in pages for them to be a match. A minus sign (-) in
front of a word means that any page that has that word is excluded
from the list of matches.
-
If you type a word all in lower case,
AltaVista will search for both lower and upper case. But if any
letter is in upper case, AltaVista searches for the capitalized
version of the letter only. Example: TryScience will match the
keyword exactly.
-
At AltaVista, all punctuation is created
equal. It doesn't matter if it is a period, a comma, a slash, an
underscore, or a hyphen -- they are all the same. You get all the
results in spite of minor variations. Example: PDP-11/70 matches
PDP1170 and PDP/11-70 and PDP_11/70, to name a few.
-
You are probably used to using an asterisk
(*) as a wildcard that can stand for missing letters or words in a
search query - the asterisk can only appear after a minimum of
three characters and can stand for from zero to five
characters.
a.) For example, if you want to search for the English spelling as well as the American spelling of a word like color (colour), you can throw in an asterisk where the "u" would be. Or you could use an asterisk to stand for either "er" or "re" at the end of a word:
colo*r
theat*
b.)You can use an asterisk to stand for the plural, so you can search for both singular and plural at the same time:
dog*
bush*
c.)You can also use an asterisk when you are
uncertain about the spelling of a word, for instance about whether
a certain letter should be doubled: carib*ean
