A Chesapeake Watershed Education Program toEncourage Stewardship in Students

A Project of BioEYES&

BioEYES Science Outreach Program

The Mission of allBioEYES projects:

• to foster enthusiasmfor science

• to promote interest inbiology-related fields

• a hands-on, student-centered approach tolearning.

Why use Zebrafish?1. Genes and organs similar to

humans2. Larvae are optically clear

Adult females can lay manyeggs every week

3. Embryos develop very quickly4. Cost effective5. Not only good model for

humans, but also for smallwatershed fish

6. Incredibly compelling forstudents

Classic BioEYES Unit

• Five day hands-on program followingzebrafish development

• Students treated as scientists and areresponsible for all embryo care

• Culminating experience - seeing thebeating heart and circulatory system

Day 1:Observing Adult Zebrafish

Living organisms:• Capture attention• Increase interest• Engage imagination

•Increase ability to relateto self•Make lessons morememorable

Day 2: Embryo Collection andObservation

Yes! We haveembryos!

How many do you count?

Day 5:Seeing the Heartbeat!

Some Statistics -Since 2001 over 18,000students have participated!

Philadelphia• Started in 2001• Over 15,000 students• Over 200 teachers trained• 3 new projects added Baltimore

•Started in 2007 with 548students and 22 teachers

•This year over 1600 studentsand 33 teachers

•Next year without YWYBprojected over 2500 students

•With YWYB funded 3700students and 66 teachers!

South Bend - Notre Dame•Started 2007•Over 700 students and 28teachers

Teachers - Important Partners

• Teachers must attend training• Teachers co-teach the unit• After 3 years, teachers run the unit themselves• Carnegie’s Science Outreach will supply all materials• Carnegie Educator can add more teachers & students to the

program

BIOEYES NEWEST ADDITION:Your Watershed, Your Backyard

• Habitats, food chains, sourceand non source pollution

• Information on local streamprojects

• Websites• Watershed related science

careers

• Education and awarenesswhile they are young

• 6th and 7th grades• Hands-on, live organisms• Stewardship

Water Collection & Water Quality Testing

Field TripStudents will do on-

STUDENTS Wrote Lab ReportsHere are some of their comments:

YOUR WATERSHED, YOUR BACKYARD

YWYB could reach 1,200students and 30 teachers inits first year Second year 1,685

students, 30 returningteachers and 10 newteachers

Third year 2,174 students,40 returning teachers and 10new teachers

That’s over 5000 students in 3 years!
