How to Choose a Science Fair Topic

I need a catchy title for my science fair project which is :The Science Behind Tsunamis: Study the Effect of Water Depth on Wave Velocity. Maybe “Making Waves: The Effect of Water Depth on Wave Velocity” or “Tsunami Tscience: The Effect of Water Depth on Wave Velocity.”

The number of possible titles for Science fair exhibits are as varied as the many projects in a science fair. A title should catch the eye of the judges, pique their interest in the experiment or model and draw them to it. Choose something you are genuinely interested in and wish to know more about.

Science Fair Ideas

• Does music affect on animal behavior?
• Does the color of food or drinks affect whether or not we like them?
• Where are the most germs in your school? (CLICK for more info.)
• Does music have an affect on plant growth?
• Which kind of food do dogs (or any animal) prefer best?

Does changing the height of a ramp affect how far a car will travel? Does the type of liquid affect how fast ice will melt? Does the type of shoe worn during a 20 yard dash affect the speed in which you can run? Does changing the size of a paper airplane affect how far it flies?

1. Interests. What are your child’s interests?
2. Research. There are lots of places to find age-appropriate science topics.
3. Teacher. Ask your child’s teacher for some good ideas.
4. “Monitored” Independence. Try to remember, this is your child’s project, not yours.

Choose a few of your favorites, and let the science fun begin!

• Crystallize your own rock candy.
• Repel glitter with dish soap.
• Blow the biggest bubbles you can.
• Build a Ferris Wheel.
• Learn about capillary action.
• Demonstrate the “magic” leakproof bag.
• Design a cell phone stand.
• Recreate the water cycle in a bag.

Best Science Experiments And Activities for Kids

• I am not kidding when I say these are the best science experiments for kids, and I have great reasons why! We do science and STEM year round here.
• Make Slime.
• Grow Crystals.
• Construct a Catapult.
• Dancing Corn.
• Balloon Baking Soda.
• Seed Jar Science.
• Frozen Dinosaur Eggs.

Examples of experiment in a Sentence Noun Students will carry out simple laboratory experiments. They did some experiments with magnets.

A good example would be an experiment to test drug effects. The sample receiving the drug would be the experimental group while the sample receiving a placebo would be the control group. While all variables are kept similar (e.g. age, sex, etc.) the only difference between the groups is the taking of medication.

Parts of a Controlled Experiment

• Independent Variable (IV)/Experimental Group (EG): The one part of the experiment that is changed/manipulated or given different treatment by the scientist (cause).
• Dependent Variable (DV): The part of an experiment that changes in response to, or affected by, the independent variable.

In a controlled experiment, an independent variable (the cause) is systematically manipulated and the dependent variable (the effect) is measured; any extraneous variables are controlled. The researcher can operationalize (i.e. define) the variables being studied so they can be objectivity measured.

Explanation: This is the best definition of a controlled experiment. A controlled experiment is a scientific test that tests the effect of a single independent variable at a time. This variable is usually adjusted to see its effects on the system that is being studied.

they are made of cells, they reproduce, they have DNA. Which of the following best describes a control group in an experiment? the control group is treated the same as the experimental group except for the one experimental variable.

The control group is composed of participants who do not receive the experimental treatment. When conducting an experiment, these people are randomly assigned to be in this group. They also closely resemble the participants who are in the experimental group or the individuals who receive the treatment.

A controlled experiment is a scientific test done under controlled conditions, meaning that just one (or a few) factors are changed at a time, while all others are kept constant.

Answer Expert Verified An alternative to a controlled experiment would be a correlation study. A correlation study is a research method in which two variables are compared (what are the similarities and the difference between them).

In Algebra, a constant is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number. Example: in “x + 5 = 9”, 5 and 9 are constants.

There must be an independent variable, which changes throughout the course of an experiment; a dependent variable, which is observed and measured; and a controlled variable, also known as the “constant” variable, which must remain consistent and unchanging throughout the experiment.

Examples of Controlled Variables Temperature is a common type of controlled variable. If a temperature is held constant during an experiment, it is controlled. Other examples of controlled variables could be an amount of light, using the same type of glassware, constant humidity, or duration of an experiment.

A variable that remains unchanged or held constant to prevent its effects on the outcome and therefore may verify the behavior of and the relationship between independent and dependent variables. Control variables are important in scientific experiments to test the validity of the results.
