The Great Book of Questions 2007-2008
From the Editor Welcome to the ﬁrst edition of the Great Book of Questions! The questions throughout this book were generated by Churchill students, ages 6-13, and posted in the Science Room and ﬁrst ﬂoor hallway during the 2007-8 school year. The goal of this project is to honor the curiosity of our students and encourage scientiﬁc inquiry. Therefore, we have deliberately refrained from providing the “one correct answer”. In science, ﬁnding an “answer” means it’s time to ask a follow-up question! Throughout the book, you will encounter clickable links that lead to text, animations, videos, and interactive games that explore scientiﬁc concepts. Many of these resources require some reading and explanation, but are enormous fun to explore. Enjoy and thank you for reading! Lisa Fischler Churchill School Learning Specialist and Science Teacher

All chemicals are made from elements. This chart shows all the known elements in the universe. The elements can combine and make BILLIONS of different chemicals.
A substance is an acid when it breaks up in water and produces hydrogen ions. This causes it to have chemical reactions when it comes into contact with other substances.

Living Things: Animals
Across long distances, animals use sound to locate each other. Some species have speciﬁc calls between parent and baby. Close up, animals often use smell. Parents might “mark” their babies with a speciﬁc smell, or just learn to notice the baby’s smell. This is why you have to be careful not to touch or pick up baby animals - their parents might not recognize them again!
When sharks attack people, it is often by accident. In the water, a swimmer or surfer might have the same shape as a seal or other shark prey. Lifespans of Different Species of Shark
Most adult female mosquitoes live only 2-3 weeks. Some species that spend the winter Life Cycle of a Mosquito indoors (such as in garages) can live as long as 6 months.

Some poisonous animals get their poison, or venom, from what they eat. However, poisonous snakes make their own venom.
The stinger and venom sac in a worker honey bee are attached to its body. When it stings, the stinger and part of its abdomen is left behind.

Each of us has a unique brain. You don’t learn or think exactly like anyone else in the world. It’s interesting and fun to learn about how you learn. How do you like to learn? Lisa likes to listen and write, and she’s pretty good with music. But have you ever noticed that she can’t ﬁnd things that are right in front of her face? She’s not very good at drawing things the right sizes or ﬁnding her way around places, either. It’s not that she “can’t” do it. She just has to work really hard at it. Sometimes it’s frustrating when you have to work hard for a long time to get something that doesn’t come naturally. Teachers and parents can help you come up with strategies to make you the best learner you can be! Check out the Brain Learn about your amazing brain! Neuroscience for Kids Arcade on Sparktop.org!

How Spacesuits Work Toilets in Space
On airlines, there is a ﬂight data recorder that keeps track of what switches are pressed and what buttons are pushed. There is also a voice recorder that uses microphones in the cockpit. The recorders are stored in the back of the airplane and kept inside a very hard, tough box that won’t burn up or fall apart. People call these machines “black boxes” but they are actually orange! How Stuff Works: Black Boxes Ink is made from powder, water, and dye. The dye is made by mixing chemicals in the factory. Different chemicals are used for different colors. Also, washable markers use different chemicals than permanent markers.

An X-ray machine is like a camera. Instead of using sunlight or a ﬂash, however, it uses X-rays to expose the ﬁlm. X-rays are similar to light, but they have more energy than light. Light does not pass through your body, but an X-ray can. When an X-ray image is taken of you, the X-ray machine sends an X- ray through your body and that image forms on the X-ray ﬁlm. Scientists also use x-rays to look at black holes and other strange things in space. They use special equipment, such as the Chandra X-Ray telescope.
