The 3rd grade is a great year for young scientists. During this year students are introduced to amazing science topics like dinosaurs, the life cycle, electricity and mechanics. This is also the year when students are first introduced to the scientific method. This is also the first year that many students are allowed to enter the school science fair. If you want to enter the science fair then the following tips will help you to develop an age appropriate science fair project that will impress the judges.
3rd Grade Science Fair Project Topics
There are a lot of great topics that you can use for your science fair project. The main categories that you can choose between include: biology, paleontology, geology and physics. From these main categories you can select from a number of great topics. For example, under the paleontology category you can select topics like fossilization, carbon dating, paleo-ecosystems and local climate changes.
Developing a Hypothesis
One of the most important steps in completing 3rd grade science fair projects is the development of a hypothesis. A hypothesis is basically just a statement that you need to prove or disprove with the data that you collect. A good hypothesis needs to examine the relationship between two very specific things. For example, if you are working on a fossil themed science fair project then your hypothesis can be, “fossilization is sped up when heat is applied.” In this hypothesis you are examining the relationship between heat and fossilization.
Conducting Background Research
You will need to conduct background research throughout the development of your 3rd grade science fair project. The first research that you conduct will be done before you even come up with a topic for your project. The next research that you conduct will be after your select your topic. This research will provide you with information about your topic and it will be used to help you narrow your topic down and to design a hypothesis. You will then conduct research as needed to help you explain or correct problems with your experiment’s design, or to help support your findings.
Designing an Experiment
The design of your experiment needs to focus on proving or disproving your hypothesis. This means that it will need to be set up so that it only manipulates one variable at a time. For example, if we look at the hypothesis mentioned earlier that “fossilization is sped up when heat is applied,” the variable that will be manipulated will be the heat that is applied to the test subject.
