Sandusky County 4-H Family Newsletter

June 2018

Dear 4-H Family,

Summer is quickly approaching, and with it, many 4-H events, programs and

get out of it. Consider trying something new this year!

The 2018 Project Interview Judging Schedule is enclosed. Please help us to keep the

wait time as low as possible by coming during the time slot assigned. If you are

unable to attend judging at your club’s scheduled time, please contact the Extension

Office.

If you have questions, please call the Extension Office at 419-334-6340. We are

June 30th at Gibsonburg Saddle Club

July 14th at Gibsonburg Saddle Club

August 4th at Gibsonburg Saddle Club

4-H Judging - July 10 Pre-fair judging will be held on:

Tuesday, July 10th at Grace Community Church in Fremont.

Only members with non-livestock projects attend this event. Livestock projects are judged at the county fair.

Each club has been assigned a time session for judging. The schedule is included with this newsletter. Please do your

best to attend during your club’s assigned time if possible. It will reduce wait times for everyone.

If you are unable to attend regular judging on July 10th

you may schedule a time for your project to be judged

early. The comments made on your interview and project

will be given to the judge at regular judging so that you

may be considered for awards.

We will be holding early judging on July 2

at the Extension Office. Please call the

Ext. Office at 419-334-6340 for appointments.

Early Judging What to Bring? The requirements for judging vary based on the project.

The Sandusky County 4-H Handbook lists the items

needed for each project under the project description.

The items listed are considered minimum

requirements and members are encouraged to

bring any extra materials they may want to share

with the judge.

Can’t Make Either Judging Date? We encourage all members with non-livestock projects to complete their project by attending Pre-Fair judging.

However we also know that sometimes busy summer schedules, family vacations, and work schedules prevent

members from making it to Project Judging. Members can still complete their project by completing a project interview

with their club advisor. (However, youth must attend one of the events above to be eligible for prizes)

County Fair BBQ Cloverbud Fun Day! Wednesday August 1st at Misty Meadows

This one day event is a perfect fit for our youngest

members. Cloverbuds will explore S.T.E.A.M

(Science, Technology, Engineering, Arts, & Math)

as they rotate through short, fun sessions and

participate in game-style challenges.

Pre-registration is required. Registration

information will be sent to all Cloverbud

members in early June. For more information call

OSU Extension at 419-334-6340.

Come be a Super Cloverbud &

find your S.T.E.A.M power!!
