THE AUTHOR

The author used the game of "Biological Baseball" many times in his over 15 years of teaching Biology in high school. The "game" may be used in other classes as well to stimulate interest and make reviewing more fun.


Biological Baseball

by Robert J. Boles

Baseball is often referred to as our national pastime. Almost all American boys and girls know the rules of the game, and many have participated in actual competition. This issue of The Kansas School Naturalist will explain bow the rules of baseball may be adapted to review the material covered in the course in biology. Past experience has shown that students enjoy and look forward to participating in a game of "biological baseball."

The game is played by dividing the students into teams, and, using questions rated as to difficulty ("singles," "doubles," etc.), the game is conducted much as in a regular baseball game.

The teacher should prepare a set of questions over the material that has been covered in class or in the laboratory. The questions should be "rated" as to difficulty. A question which a majority of the students should know would be a "single," or "one-base hit." A more difficult questions would be rated a "double." Questions with a rather high degree of difficulty would be worth three bases. Those questions requiring an excellent knowledge of the subject material would be designated "home runs" and would "clear the bases."

The teacher may want to have the students write some of the questions to be used in the game (e.g., ten questions per student).

It is usually best to type the questions on 3 x 5 cards, along with the degree of difficulty (how many bases?). The cards can then be shuffled as you would a regular deck of cards, in order that no one will know the order in which the questions will be asked.

You may wish to have a student draw a baseball diamond on a sheet of poster board. The drawing may then be placed on a bulletin board, and the runners' position shown by colored pieces of paper held in place with thumb tacks or map pins.

Teams

The simplest way to select teams is to divide the class into halves (e.g., East three rows vs. West three rows). The girls may wish to challenge the boys, or vice versa. One class may wish to schedule a "game" with another class (e.g., first hour challenge third hour). A "World Series" of "All Stars" between two neighboring schools is also a possibility.

Some of the best times to have a game of "Biological Baseball" are when reviewing the material before a major test, or when the students are restless, due to some distracting events, such as before a home athletic contest, or before the start of a vacation period.

The following rules will allow all participants to operate under the same set of guidelines, and will serve to keep down arguments and disputes during the game.

A rough sketch of a baseball diamond on the chalkboard will suffice. Runners may be indicated by an "X" by (he proper base, and the "X" erased when the runner is advanced or the team is out.

RULES OF THE GAME

Length of a game

Though a regular baseball game normally consists of nine innings, the length of a game of Biological Baseball will usually be determined by the length of a class period. A game may be "postponed because of the bell," and play resumed at the start of the next period, if the class wishes.

"At bat"

A team will be "at bat" until three "batters" have been retired. It will be agreed that:

a. Answering a "single" question correctly will send the batter to first base. A runner on first shall be advanced to third, and a runner on second will score.

b. A "double" or "triple" question will score a runner from any base.

c. A missed question is an "out."

d. A partially correct answer will be a "sacrifice" and advance a "runner" who might be on base, but the batter will be out. If no runner is on base, the batter giving the partially correct answer will be considered out.

baseball score board

A "score board" may be drawn on poster board, and tacked to the bulletin board. The number of runs each inning may be indicated by placing a card with the appropriate number of runs scored marked on it in the proper blank by means of a thumb tack.

An Inning

Each team will be permitted three outs per inning. All runs scored before three outs will be entered on the score board.

Interference

Should a student on the "at bat" side give any help by whispering an answer, or otherwise give some clue as to the correct answer, it shall be ruled "offensive interference," and batter declared out.

If one of the team members "in the field" is guilty of trying to distract the batter in answering his question, it shall be ruled "defensive interference" and the batter sent to first, and all runners on base advanced one base.

baseball scoreboard

A "score board" may be sketched on the chalkboard, and the number or runs each inning written in the appropriate blanks.

Pitcher

It is usually best if the teacher read off the questions to be answered, though he may sometimes select a student to be the "pitcher."

Umpire

Regardless of whether the teacher reads the question, or selects a student to do the pitching, it is best if the teacher assume the role of the umpire, to decide if an answer should be counted as correct or not.

TERMINOLOGY

Pitcher -- the person asking the questions.

Umpire -- the person making the decision as to the correctness of an answer. He shall also rule in cases of interference.

At bat -- the team whose turn it is to answer questions.

In the field -- the team awaiting its turn to be at bat.

Batter -- the student attempting to answer the question.

Hit -- a question answered correctly.

Sacrifice -- a partially correct answer. The batter shall be out, but any runners on base shall be advanced one base.

Interference -- to attempt, by sign or word, to help a batter give a correct answer (offensive); to attempt, by sign or word, to cause a batter to give an incorrect answer (defensive).

Out -- a missed question.

Game -- the number of innings that can be played in the time available. A game may be "delayed because of time," and continued at the next period, if desired.

Inning -- when each side has played until it has made three outs. If the bell rings during the inning, the score shall revert back to the last completed inning.

SCOREBOARD

Score may be kept by drawing a scoreboard on the chalkboard. Scores can then be written in in chalk, as can the number of outs. This is probably easiest when the teacher has several sections of biology.

Some student may want to make a scoreboard for his class from posterboard, and the score can then be kept with a felt-tipped pen, or the number of runs each inning indicated by using a card with the appropriate number, held in place by a thumbtack. Use of the felt-tipped pen makes it necessary to prepare a scoreboard for each class, but the scores can be kept for later reference, if needed.

BALL DIAMOND

A ball diamond may be drawn on the chalkboard. This permits the keeping track of where a player is on base by checking his position with chalk, and erasing the stranded players when the other team comes to bat.

A more elaborate diamond may be drawn on a large piece of poster board or pressed wallboard. Positions of runners may then be designated by a colored piece of paper held in place by a thumb tack.

TWENTY QUESTIONS
(Another "oldie-but-goodie")

Some of you teachers who have been in the profession for a considerable number of years may remember a TV program entitled "Twenty Questions." The rules of the program lend themselves well to creating student interest and getting the student to think in biological terms.

Rules of the game

a. Divide the class into teams.
b. Choose a structure, term, organism, or concept in the biological field.
c. Inform the team whose time it is to ask questions as to whether the item to be identified is in the plant or animal kingdom.
d. Let the other team know the item being identified.
e. A team will be permitted twenty questions to identify the item.
f. Questions should be asked so as to be answered by a "yes" or a "no."
g. The number of questions needed to identify the item will be charged against the team. If a team fails to identify an item in twenty questions, twenty points will be charged against it, and the other team then be given a chance to identify a new item. As soon as an item is identified, the other team will take a turn at identifying a new item.
h. The team with the fewest questions charged against it (as in golf) at the end of the game will be declared the winner.

Example I

Suppose the item chosen for identification is a whale. The team whose turn it is to ask questions is informed that the item is in the animal kingdom. Questions might procced as follows:

IQ. Is it a large animal?
A. Yes.

2Q. Does it live on land?
A. No.

3Q. Does it have to live in the water?
A. Yes.

4Q. Does it have gills?
A . No.

5Q. Is it warm-blooded?
A. Yes.

6Q. Is it a whale?
A. Yes.

Six points would be charged against the team, and the other team then be given a chance to identify a new item.

Example II

The item to be identified might be the word "stamen." The team to ask questions should be told that the item is in the plant kingdom.

1Q. Is it a large plant, such as a tree?
A . No.

2Q. Is it a flowering plant?
A. No.

3Q. Is it a part of a plant?
A. Yes.

4Q. Is it a part of a plant that is below the ground?
A. No.

5Q. Does it have something to do with the fruit or seeds of the plant?
A. Yes.

6Q. Is it a flower?
A. No

7Q. Is it a part of the flower?
A. Yes.

8Q. Is it a part of the male reproductive structure?
A. Yes.

9Q. Is it a pollen grain?
A. No.

10Q. Is it the structure that produces pollen grains?
A. Yes.

Ten points would be charged against the team, and the other team then given a chance to identify a new item.
