Expository Essay- Science Fair Project.(One page essay)

Students are expected to explain the process of a Science Fair Project,

as published in Teaching ESOL Through Science Fair Experiments, by Judie Haynes.

Structure Expository Essay, published on student’s weblog (including all prewriting).

Procedure Students log on to class weblog/ formative page and download the following files: EXPOSITORY SCIENCE FORMATIVE SCIENCE PROJECT

The EXPOSITORY SCIENCE FORMATIVE file should be immediately published onto the student’s weblog.

The above files contain all the information needed to complete this exercise.

Students’ production

By Wednesday 8 th December, 2010, students will have completed their work.

Students are required to publish updates of their file, progressively.

Teacher will then comment on individual student’s 9. PUBLISHED WORK- ORIGINAL and email it to them for pasting to the final page of their file;11.PUBLISHED WORK - TEACHER’S COMMENTS

Objectives

Students will display knowledge of the elements of an Expository Essay by explaining the process, in logical order, for a science fair experiment.

http://www.writingcnep.weebly.com PROJECT EXAMPLE Question: Why do Diet Coke and Mentos react like they do when put together?

Hypothesis: Explore the wonders of the Mentos and Diet Coke geyser.

Materials: 1) Mint Mentos (candy mints) 2) Large bottle of Diet Coke 3) Test Tube (or some creative insertion device)

Variables: When Mentos and Coke mix the result is volcanic!

Procedures: 1) Unwrap the Mint Mentos, 2) Put them into a tube of any sort, 3) Uncap the diet coke, and 4) Dump them in and run.

Results: When you drop the Mint Mentos candy into the Diet Coke it starts to foam and erupt into the air.

Conclusion: There are many factors that cause the physical reaction. Ingredients contained in the Diet Coke (Carbon Dioxide gas, benzoate, caffeine, aspartame, potassium) and Mentos mints (gelatin and gun arabic) react when combined together. However many scientists think the primary cause of the eruption reaction may be attributed to the physical makeup of the Mint Mentos candy itself and the nucleation on the surface. Nucleation on the surface of the mint Mentos is evidenced by all of the tiny little holes found there. These small nucleation holes permit Carbon Dioxide bubbles to form very fast and grow rapidly when the Diet Coke is added.

ORIGINAL DRAFT

Have you ever try experiment of mixing diet coke with mentos? It’s amazing to know that the drinks we used to drink like coke and the candy which named mentos can cause eruption. In this science experiment we will explore the wonders of the Mentos and Diet Coke geyser. We will also attempt to explain why and how it works. When Mentos and biggest dropCoke mix the result is volcanic! Other carbonated soda drinks can be used as well but Diet Coke seems to produce the best reaction. Experiment with different types of sodas and log your results to see which makes the big reaction.

Other people prefer to make the bottle go like a rocket by first putting the Mentos inside the Diet Coke and then screwing the cap back on. After which they slam the bottle into There hard ground cap first. It takes off like a rocket!

Their are many factors that cause the physical reaction. Ingredients contained in the Diet Coke (Carbon Dioxide gas, benzoate, caffeine, aspartame, potassium) and Mentos mints (gelatin and gun arabic) react when combine together. However many scientists think the primary cause of the eruption reaction may be attributed to the physical makeup of the Mint Mentos candy itself and the nucleation in the surface. Nucleation on the surface of the mint Mentos is evidenced by all of the tiny littles on combined holes found there.

When you drop the Mint Mentos candy into the Diet Coke it starts to foam and erupt into the air. Dont use the fruit Mentos because they have a smoother surface that will produce a small or no reaction at all. The Mentos and Diet Coke experiment is an example of a physical reaction.

The reaction can be used to demonstrate how a Volcano or Geyser erupts. Other people prefer to make the bottle go like a rocket by first putting the Mentos inside the Diet Coke and then screwing the cap back on. After which they slam the bottle into hard ground cap first. It takes off like a rocket!
