The Eggciting Physics Egg Drop!

“Did it break?” That is the question of the day in Mr. Baxter’s Physics classroom, as students learn about momentum and impacts while designing egg drop contraptions.

 

The rules? Each team of students must design a vehicle that will protect a raw egg during two drops. The first drop is from the ceiling to the floor in the classroom. The second drop is a two-story drop in the front foyer of GHS. Materials such as cotton, bubble wrap, drinking straws may be used.

 

Students learned to work with key Physics ideas such as reducing speed, spreading the force of impact over as much of the egg as possible, and increasing the duration of the impact.

Will the teams crack under the pressure? Which teams would be beaten? The action is on the next page!

Students were really “egging” each other on! Stop yoking around!

With a Name Like Deoxyribonucleic Acid, It Has To Be Good!

What are all the strawberries for? Are Mrs. Buebe’s Biology students making strawberry jam or pie filling? Are they canning and putting up preserves just like Grandma used to do years ago? Nope! Instead, these Biology students have learned to use detergent and salt to extract DNA from strawberry cells.

Mass Extinction Blues

Earth Science students in Mrs. Buebe’s classroom are making posters and presentations to show what they have learned about mass extinctions that have taken place on the earth in the past.

Buebe’s students sure to find,

His-tor-y can be unkind,

Ice age, virus, meteorite,

Volcano turning day to night, ...


(C’mon, lemme hear you sing that chorus!)


I got d’em mass extinction blues, but I’m gonna leave some clues,

Let the fossil record show, that I didn’t want to go …

Karyotypes

Biology students in Mrs. Buebe’s Biology classes are learning to work with chromosomes, sorting them by size, form, and type. When an organism’s complete set of chromosomes is organized like this, it is called a karyotype. Now instead of asking someone, “Hey, what’s your sign?” they can ask, “Hey, what’s your karyotype?”
