The Revised Simpson-Troost Attitude Questionnaire (STAQ-R) is a revised version of the original tool – the Simpson Troost Attitude Questionnaire (STQ), a 58-item Likert type scale created by Simpson and Troost in 1982.  Used with middle school students, the STAQ-R is comprised of 22 items, and each is measured on a 5-point Likert scale.  

The Fennema-Sherman Mathematics Attitude Scale measures student attitudes towards mathematics. The survey consists of 4 subscales, each designed to measure confidence, math as a male domain, teacher perception, and usefulness.

The Draw-a-Scientist Test is an open-ended projective test that assesses children's conceptual images of scientists.  The DAST is evaluated using a 7-point scale based on the presence of the following components in drawing: lab coat, eyeglasses, facial growth of hair, symbols of research, symbols of knowledge, technology & relevant captions.

The Changes in Attitudes about the Relevance of Science (CARS) instrument was developed to measure (a) change of science-related attitudes over time among middle school and high school students, and (b) the effect of similar curricula on the attitudes of different classes.  This instrument uses 25 items, each using a 5-point Likert scale.  There are three forms of this instrument (A, B, and C); these forms share 8 items, and the other 17 items are unique to the form.

The Modified Attitudes towards Science Inventory (mATSI) measures students' attitudes towards science related to such factors as students' perceptions of the science teacher, anxiety toward science, value of science in society, self-concept toward science and desire to do science.  This 25-item inventory uses a 5-point Likert scale.

The linked website contains the mATSI as well as information and reviews about it.  

The Children's Science Curiosity Scale (CSCS) measures elementary school children's attitudes towards science in a learning context.  Originally used with 5th grade students, it is comprised of 30 items, each using a 5-point Likert scale.  Validity and reliability studies have been done on this scale.
