1.	I have reviewed this report on Form 10-Q for the quarter
ended September 30, 2013 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;

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.
