Students Make Rockets At Annie Sullivan Elementary


Sioux Falls students are celebrating National Science Week. This year’s theme is ‘out of this world.’

These AP Chemistry students from Washington High School are teaching these Anne Sullivan 1st graders about the importance of oxygen.

“We were talking about how astronauts need oxygen in space since there’s no oxygen,” junior Jasmine Johnson said.

Using antacid tablets and water inside a small canister, the students are creating their own rocket ships.

“When we added the Alka Seltzer tablet to the water and we put the cap on it, it kept all the gases, which is CO2, or carbon dioxide from going out of the canister,” junior Jack Glenn said.

And after a few seconds…

“When it exploded it shot up in the air,” 1st grader Yohana Muluget said.

“If you put more water and less Alka Seltzer, the less gas is going to be produced and less of a reaction is going to occur, so the rockets won’t shoot up as far, but if you put less water and more Alka Seltzer, which we learned last year in accelerated chemistry then it will shoot up farther,” Johnson said.

Leaving these students taking their learning to new heights.

“I think they had fun because we were there to help them and they could learn from it and they were starting to understand what we were teaching them,” Glenn said.

The students also did an experiment called ‘elephant toothpaste’ where they showed a reaction using hydrogen peroxide, dish soap and sodium iodide.
