Noel Stu­dents Com­plete Sci­ence Fair Projects

McDonald County Press - - COUNTY - Rachel Dick­er­son

Noel Ele­men­tary and Ju­nior High School had its an­nual sci­ence fair on April 12. Some stu­dents shared their projects in ad­vance of the event.

Eighth-graders Mar­i­ana Salas and Moosay Raysoe stud­ied the growth of bac­te­ria on dif­fer­ent sur­faces.

Raysoe said they used cot­ton swabs to swab dif­fer­ent sur­faces, such as a sink, chairs, a hand, a toi­let han­dle and the in­side of some­one’s mouth. Then they swabbed them on a Petri dish, closed and taped the lid, put the dishes un­der a warm light and waited a few days for bac­te­ria to grow.

“We found out the sink had the most bac­te­ria,” Raysoe said.

Their sci­ence teacher, Mr. Boet­tler, gave them the in­struc­tions for how to do their ex­per­i­ment, they said.

“We were sur­prised. And we’re proud,” Raysoe said.

Eighth-graders S.J. Joseph, Amy Mon­toya and Julis Quet­ze­cua did a pro­ject about how mu­sic af­fects the mem­ory.

Mon­toya said they set out to de­ter­mine which genre of mu­sic would help them con­cen­trate more.

The stu­dents said they played a match­ing game while lis­ten­ing to dif­fer­ent gen­res of mu­sic and tried to see how many puz­zles they could com­plete.

“We found that rock mu­sic helped us way more than any other genre,” said Mon­toya.

Both groups pre­sented their find­ings on boards at the sci­ence fair.

Noel prin­ci­pal Sa­man­tha Buck­ridge said, “We just want stu­dents to en­gage in hands-on sci­ence projects where they can, from start to fin­ish, go through the sci­ence in­quiry process and then cel­e­brate their work with the rest of the com­mu­nity.”
