                     CERTIFICATION

I, Helena R. Santos, certify that:

1.	I have reviewed this report on Form 10-Q for the
quarter ended March 31, 2015 of Scientific Industries, Inc.,
a smaller reporting company (the "Registrant");

2.	Based on my knowledge, this report does not contain
any untrue statement of a material fact or omit to state a
material fact necessary to make the statements made, in light
of the circumstances under which such statements were made, not
misleading with respect to the period covered by this report;

3.	Based on my knowledge, the financial statements, and other
financial information included in this report, fairly present in
all material respects the financial condition, results of
operations and cash flows of the Registrant as of, and for, the
periods presented in this report;

4.	I am responsible for establishing and maintaining disclosure
controls and procedures (as defined in Exchange Act Rules 13a-
15(e) and 15d-15(e) and internal control over financial reporting
(as defined in Exchange Act Rules 13a-15 (f) and 15d-15(f) for
the Registrant and have:

a)	Designed such internal disclosure and procedures, or caused
such controls and procedures to be designed under my
supervision, to ensure that material information relating to
the Registrant, including its consolidated subsidiaries, is
made known to me by others within those entities,
particularly during the period in which this report is being
prepared;
b)	Designed such internal control over financial reporting, or
caused such internal control over financial reporting to be
designed under my supervision, to provide reasonable
assurance, regarding the reliability of financial reporting
and the preparation of financial statements for external
purposes in accordance with generally accepted accounting
principles;
c)	Evaluated the effectiveness of the Registrant's disclosure
controls and procedures and presented in this report my
conclusions about the effectiveness of the disclosure
controls and procedures, as of the end of the period covered
by this report based on such evaluation; and
d)	Disclosed in this report any change in the Registrant's
internal control over financial reporting that occurred
during the Registrant's most recent fiscal quarter that has
materially affected, or is reasonably likely to affect, the
Registrant's internal control over financial reporting; and

5.	I have disclosed, based on my most recent evaluation
of internal controls over financial reporting, to the Registrant's
auditors and the audit committee of the Registrant's board of
directors (or persons performing the equivalent functions):

a)	All significant deficiencies and material weaknesses in the
design or operation of internal controls over financial
reporting which are reasonably likely to adversely affect
the Registrant's ability to record, process, summarize and
report financial information; and
b)	Any fraud, whether or not material, that involves management
or other employees who have a significant role in the
Registrant's internal controls over financial reporting.
