But how can we be sure that this history really happened? The story was “in theTimes. Tomorrow morning,” the parent says,  “I’ll read it to you.

Who would Win

Who Would Win? Killer Whale vs. Great White Shark.  This is a non-fiction book written by Jerry Pallota and illustrated by Rob Bolster. It was published in 2009 by Scholastic. One of the creatures is known for being a “gentle giant”; the other is known as the most feared predator of the ocean. But, in a 1 on 1 battle, who would win? This book gives readers all the information they need to know in order to answer that question.
The author increases your curiousity and knowledge page by page with both scientific facts and fun “did you know” facts. The language used in the book is easy to understand and the text changes often, this helps to keep the reader interested.  The facts that the author wants to highlight are surrounded in comic style boxes and bubbles. The illustrations are both realistic pictures or diagrams and fun cartoons.
In the beginning of the book, each page lists a fact along with a picture or drawing.  The reader is told about things like the size of each animal, the speed that each animal can swim, the size of each animals jaw and teeth. The author uses everyday objects for the reader to compare sizes to, this helps to create a picture in your mind of what these animals actually look like. The reader also learns about the habits of each of the animals, what they like to hunt, or where they live.
Towards the end of the book, the author has activities such as checklists for the reader to do.  The author reminds the reader that if you keep reading, you will learn the answer to the questions.
The last few pages of the book ask the reader to make a choice as to who would win the battle.  Finally, on the last page of the book, the reader learns that the Killer Whale would win if the two animals were to get in a fight.
I think the author did a great job of making this fact-filled book exciting and fun to read. (Maya in grade eight)


Toxins in the Food Chain

Toxins in the Food Chain by Sarah Levete (Crabtree, 2010) made me aware of the impact of toxins on our planet. Toxins are endangering our wildlife, harming our environment and maybe even destroying our future. Did you know that the global warming is spreading toxins into new environments? In Costa Rica, the unusually warm weather has increased the strength of toxins from the chemicals used on crops in the low lands. Warm air always rises, and the warm air containing concentrated toxins has reached cloud forests and is poisoning both animals and plants. Chemicals sprays used to protect our food are entering our food chain and causing long-term effects on our body. The frothy scum you find on rivers or beaches is actually detergents and chemicals found in cleaning products that are washing up on our shore. The chickens that we buy at our local food stores could be the chickens that have been given growth hormones, been crammed in small sheds and fed many antibiotics, which enter our bodies when we eat them causing our bodies to not respond to antibiotics when we need them. This book is full of information that everybody should know and be aware of. (Natalie)

Supply and Demand

Supply and Demand by Gare Thompson (Crabtree, 2010) is full of information about taxes, goods and services, trade, importing and exporting, insurance, mortgages, loans, credit work and supply and demand.
Have you ever wondered why there are not many expensive sports cars at local car dealerships? One reason is that manufacturers create a shortage of sports cars to keep both the demand and the price high. When demand is high and supply is low, prices generally go up.
Bikes have also became more popular nowadays as people try to save money on gas and stop pollution. An increased demand for bikes has increased the prices.
As prices continue to rise for all products and become less affordable for consumers, a black market has been created. People illegally buy and sell goods without paying taxes. This illegal buying and selling of goods usually takes place out of sight or sometimes under the cover of dark.
A free market economy is when a country buys and sells things without interference in the form of taxes and tariffs from the government or outside sources. Canada has a free market economy for its sale of goods, such as oil, to other countries.
These are a few interesting facts that I learned from this book. I recommend all teens and parents read this book to learn more about economics and economies. (Natalie in grade eight)

Why Should I Bother to Keep Fit?

Why Should I Bother to Keep Fit? by Kate Knighton and Susan Meredith (2008, Usborne) is an interesting and informative book about how to stay healthy and fit using fun and creative ideas.

Exercise is any kind of physical activity – vigorous, moderate or light. But, remember to always warm-up and stretch properly before doing any strenuous exercise. Try to do activities that help improve you stamina, strength and suppleness. This book is full of important information that I think all teens should know! (Natalie in grade eight)


Beavers, by Deborah Hodge, is full of lots of interesting facts about beavers. Some of the facts I already knew, but others surprised me. For example, did you know beavers are rodents?!? They are related to the muskrat, the nutria and the capybara. This book also states where beavers live, how they make their homes and dams, how their body works, how they are born and much more.
Beavers have very powerful jaws. Their front jaws are used to protect themselves from predators such as bears, coyotes, wolves, cougars, foxes, lynx and their main enemy, the otter. They also use their front jaws to chew the bark off twigs and branches. Beavers use their back teeth to grind up the bark once they chew it off. They have a gap between their front and back teeth which is used for carrying twigs.
Beavers have webbed feet to help them swim, but that makes it hard for them to walk on land, although their tails help balance them. They can swim underwater for fifteen minutes because their heart slows down so they need less air.
Beavers make dams from five to thirty metres across. They make them by wedging sticks into a stream bed in a row. Next, they put mud and rocks on the sticks to keep the sticks down. They put branches and grass in between the sticks and put mud everywhere to stop the water from passing through. Beavers can finish a dam in two to three days, then they have a deep pond.
Beavers also make homes, called lodges, using sticks, rocks, and mud. The lodge helps keep them warm throughout winter. Some lodges can last for 30 years. When a mother beaver gives birth, the family cleans the lodge, and the mother has three or four babies. When the kits are born, they can already hear, see, walk, and swim. Every spring, beavers have a litter of kits! They leave home and find their own mates at two years of age.  I found this book full of interesting facts. I couldn’t believe how much I could learn about beavers. This book expanded my knowledge, because before I just thought they made dams, but there is much more to their life. (Sydney)


I read Space by Ruth Owen (Crabtree, 2010). I chose this nonfiction book because I wanted to know how astronauts get ready to go to space. Before I even started reading, I already knew that astronauts preserve their own food before going out to space. I also knew that astronauts need to have their space suits to survive in space. Another fact I knew was that astronauts must train hard to be able to go to space. Reading this book, I learned a lot more: astronauts take a medical training session; NASA astronauts sometimes fix their spacecrafts; astronauts sometimes have to leave the safety of their spacecrafts and go on space walks or EVA; space suits have 14 different layers including visors covered in thin layers of gold to protect astronauts from the Sun¡¯s harmful rays. Now I wonder, can people ever live in space? This book started me thinking more about space and how astronauts train to go to space. (Da Eun)
