Science Fair - Kentucky Department of Education



Science Fair

Parents,

The third grade will be having a Science Fair the last week of March. The projects are due for Mrs. Gullett’s and Mrs. Newland’s classes on Monday, March 30th. They will be judged on the 30th and 31st, and will go home on the Wednesday, April 1st. This year, we are asking that each student base his or her project on the Scientific Method. A simple version of this follows:

1. Think of an idea.

2. Research your topic.

3. Plan your experiment.

4. Do the experiment.

5. Collect and record data.

6. Come to a conclusion.

The students should use a tri-fold poster to display their projects. Students do NOT need to write a report. The following information must be included on the poster

1. Project Title

2. The Problem or Question

This is what needs to be solved or answered. It is the reason that the experiment will take place. For example: Is a goldfish more active in cold water or warm water?

3. Hypothesis

The hypothesis is an educated guess that answers your question. For example, I believe that gold fish are more active in cold water.

4. Procedure

The procedure is a set of step-by-step directions to carry out the experiment.

5. Results

The results are what you find out. This can be shown in words or in a graph.

6.Conclusion

The students must decide if the results proved the hypothesis true or false.

I encourage students to receive help with their projects, but the student should do most of the work. The students should be able to answer questions about their projects. On the back is a list of possible topics. However, students are not limited to these.

• Do ants like sugar better than cheese?

• What type of birdseed do birds prefer?

• Does heart rate increase with exercise?

• Can objects be identified by the sense of smell?

• Does sound travel better through solids, liquids, or gases?

• How does water move in plants? ( Hint: Place celery in colored water)

• On what part of the tongue do most people sense a salty taste?

• On what part of the tongue do most people sense a sweet taste?

• On what part of the tongue do most people sense a bitter taste?

• What objects sink in water?

• What kind of cereal contains the most iron?

• What type of bubble gum makes the biggest bubble?

• Which brand of paper towel is the strongest?

• How long does it take for one cup of water to evaporate?

• How much salt must be added to a glass of water for an egg to float?

• What objects float in water?

• What type of cereal gets soggy first?

• How much juice does an orange hold?

• What happens to an egg stored in a container of vinegar?

• Does a small ball roll a greater distance than a large ball?

• How does a cooked egg differ from a raw one?

• How many marshmallows are in a box of cereal containing marshmallows?

• Does a ball roll the same distance in dirt as it does in grass?

• How far can a water balloon be rolled before it bursts?

• How much liquid does a Popsicle contain?

• How many times can a piece of paper be folded in half?

• What type of juice best cleans coins?

Students can choose one of those topics or come up with their own. The most important thing is that they choose something they are interested in.

Thanks,

Mrs. Newland

Mrs. Gullett
