The color of food might affect just how much you want to eat them，but what about the birds in your neighborhood？Would they care what color their food is？Try this out for a science fair project，or just to learn something new while making your local birds happy.

Begin this experiment with the question“What color of birdseed（鸟食），if any，will birds like the most?”, and then make a hypothesis (假设) based on your question. An example might be“Birds will eat more green birdseed than other colors of birdseed.”

You should get several bird feeders. Purchase birdseed that is very light in color. To color the birdseed, pour it into a bowl and then add food coloring that you can purchase from the store. Mix them up well with a spoon and continue to add coloring until all the seed is colored. You should sample at least a few colors and have one feeder with seed that has not been colored—this is called the control and it will give you something to compare your results to. Now just hang them up outside in the same location，and wait for your feathered friends to show up. This works best in an area where birds are used to feeding from a feeder—it can take birds over a week to find new feeders.

Observe your bird feeders whenever possible，and keep track of how much seed is in each bird feeder each day. A ruler is helpful for this. You might also want to take pictures of the feeders and keep track of what kind of birds visit each feeder. Over time，you should be able to see if one color of seed gets eaten more than others.

Once your experiment is done，you will be able to go back to your hypothesis and see if it is correct. Remember, it’s not bad if your hypothesis was wrong. The main thing is that you’ve learned something from your experiment，and hopefully you had some fun doing it.

1.What’s the purpose of this experiment?

A.To see what color birds like most.

B.To make local birds happy.

C.To see if the color of food affects birds.

D.To find how local birds feed themselves.

2.What’s the second step for this experiment?

A.Observing bird feeders. B.Raising a question.

C.Collecting all the data. D.Making a hypothesis.

3.The underlined words“feathered friends”in Paragraph 3 refer to　　　　 .

A.feeders B.birds

C.neighbors D.locals

4.What is the most important about the bird feeders?

A.They are filled with some water. B.They are placed in secret places.

C.They are painted in different colors. D.They are all the same size and type.
