Ninth Grade, Chemistry Science Projects (40 results)

An experienced chemistry professor used to say that it took about one explosion per week to maintain college students' attention in chemistry lectures. At that rate, we'd get in pretty big trouble with a lot of parents and teachers! Don't worry, we still have lots of bubbles, fizzes, bangs, and color changes for you to explore.

Science Fair Project Idea
The makers of sports drinks spend tens to hundreds of millions of dollars advertising their products each year. Among the benefits often featured in these ads are the beverages' high level of electrolytes, which your body loses as you sweat. In this science project, you will compare the amount of electrolytes in a sports drink with those in orange juice to find out which has more electrolytes to replenish the ones you lose as you work out or play sports. When you are finished, you might even… Read more

Have you ever made your own ice cream? If you have, you probably know that you need to get the ice cream mixture really cold to freeze it quickly. Ice cubes alone will not do the job, but if you add chemicals, such as salt or sugar, to the ice cubes that surround the ice cream container, the mixture gets cold enough to freeze. Why does that work? How does adding salt or sugar affect the freezing point of water? Find out with this ice-cold science project and use your results to make your own… Read more

Which type of orange juice has the most vitamin C? In this science project, you will learn how to measure the amount of vitamin C in a solution using an iodine titration method. You will compare the amount of vitamin C in three different types of orange juice: homemade, premium not-from-concentrate, and orange juice made from frozen concentrate. Which do you think will have the most vitamin C? Read more

Watching a spacecraft launch is an amazing experience. It is thrilling to see it lift off and escape Earth's gravity. Did you know that it takes a chemical reaction to get a spacecraft into space? Every time you see a one blast off, you are watching chemistry at work. In this chemistry science fair project, you will also get to blast an object into the air. You will not be using the same fuel that NASA uses for the rockets that launch their spacecrafts; instead, you will use two simple… Read more

Do you read the list of ingredients in foods and drinks before you buy them at the grocery store? If you do, you may have noticed that many of the items, especially colored drinks, contain dyes with names such as FD&C Blue 1, Red 40, or Yellow 5. But how much dye is needed to create all these colors? In this chemistry science project, you will build a simple spectrophotometer that is able to measure the concentration of colored chemicals in solutions. You will test your device by measuring… Read more

Science Fair Project Idea
Solar cells are popping up on rooftops everywhere these days and are a model for clean, renewable energy. Did you ever look at those solar panels and wonder how we can get electricity produced by solar cells when the sun is not shining? It is a great question because solar panels do not produce electricity when it is dark outside. One strategy to overcome this challenge is to store the energy produced by solar cells during the day in the form of a fuel that can be used at a later time. In… Read more

Soap comes in many varieties and forms—from bars to bottles to boxes. The uses for soaps are just as expansive—from cleaning our hands, hair, and faces to a variety of household cleaning jobs, such as dishes or laundry. One thing all these different soaps have in common is their chemical origin; they were all made by mixing fat or oil with a strongly basic solution, such as lye. In this chemistry science project, you will carry out the chemical steps needed to transform coconut oil… Read more
