If you could look at a single drop of your blood under a powerful microscope, you’d discover a miniature world of living organisms that help you live, grow, and stay healthy. Contained inside your body’s blood system are two special kinds of cells. Some cells are red and carry nutrients and gases throughout your system. Other cells are white, and, like soldiers, battle invading germs to keep you in tip top shape. When you get a shot at the doctor’s office, you may be “immunized” from certain diseases that may enter your blood stream. This issue tells you how that happens, and invites young readers to scour the news for health-related articles and advertisements. Meet the “polio police” and help them locate the unwanted invaders. Learn health vocabulary words in context, and understand why sometimes we need shots—even when we aren’t sick!
In this issue budding biologists will:
- Read informational text about blood cells, immunizations and germs
- Differentiate between the functions of red cells and white cells
- Understand how immunizations provide protection from certain diseases
- Use the newspaper and a tracing of your body to connect health articles in the news
- Read carefully to edit spelling and grammar errors
- Locate advertisements for health-related products
- Write rules to keep your classroom safe and protected
