The Current research aims to identify the effect of Brain Storming in the achievement The Biological Concepts of the Female Pupils at the Intermediate Stage.

and accordingly, hypothesis was formulated as following: - the null hypothesis: There is no statistically significant differences at the level (0.05) between the average degrees of the experimental group students who studied according to Brain Storming and the average degrees of the control group students who studied according to the traditional method in the achievement test .

The present study is limited to the first-grade intermediate female students in Misan Province in 2010-2011.

The researcher determined the material by the first three chapters from the first-grade biology textbook (2009).The research sample consists of (67) students ,which was divided to two groups ( 35 ) students for the experimental group and ( 32 ) students for the control group .

The two groups were equalized with some variables that might affect the independent variable : 1-Pre-achievement in the subject matter of biology .

2-Pre- knowledge of the scientific materials .

The Researcher put tool for the study: achievement test multiple-choice consists of ( 40 ) that measures the three levels of Bloom (remembering , comprehension , application).

, both face validity and content validity are verified.

By using the (K.R.-20) , the reliability of the test reached to (0,80).

After the experiment and data analyze the study arrived at the following results: statistically significant differences between the experimental group and the control group in achievement test on the behalf experimental group studied according to Brain Storming.
