Los Primates

Readers may never expect that they might free fall to Earth, but if they have ever dived into a pool, that's exactly what they've done. This book shows readers how Newton's three laws of motion affect divers, skydivers, and mountain climbers' movements. Readers discover who uses gravity, and who works against it, and all other forces that contribute to a successful dive or climb. After reading this book, readers can decide if they will ever be interested in engaging in one of these extreme sports.

Even as the world changes, skilled labor will always be needed. There's nothing quite like the ability to create things with your skills and your own hands. Carpenters use their skills to build things we use every day, including items such as furniture, buildings, and bridges. They read building plans, choose materials, design, and create. This book teaches kids that to become a carpenter, you have to use a lot more than a hammer and nails; you need your brain too. Photographs and diagrams enable readers to make key connections with the text.

Charles Dickens escribió la primera novela que tuvo a un niño como protagonista. En sus relatos describía las duras condiciones en las que vivían los niños hace poco más de un siglo. También fue el escritor más famoso de la lengua inglesa en su tiempo: reunía multitudes en cada aparición pública. Todo esto nos lo cuenta un pequeño vendedor de periódicos un día de junio de 1870. Charles Dickens acababa de morir.
