1. The first submarine was built in the year 1620 by Cornelis Drebbel, a Dutch scientist, to help exploration underwater and as a method for future combat underwater. 2. The largest island in the world is Greenland, having a surface area of 2.17 million km². 3. Canada has the
Biology
Chromosomes and Genes Every organism inherits traits from their parents. These traits can include how something looks, how it acts, and how likely it is to get certain diseases. The storage location for these traits are the genes. These are passed from the parent to the child. For example, if

Nemo, a captain, a navigator, an engineer, and an avenger, from the book 20,000 Leagues Under the Sea, is a very interesting character. The captain, is revealed to be a man of Indian descent who was fighting against the nation that killed his family while providing resources to oppressed
Biology
Ecosystems Ecosystems are dynamic, which means that they change over time, either for the better or worse. These systems can often times experience disruptions in either the living or non-living parts of the system. Every change can affect the populations of the system. * A change can impact the populations negatively,
Biology
Photosynthesis in Ecosystems Energy from the sun is converted into chemical energy by plants through the process of photosynthesis. Plants take water from the ground, C02 from the air, and energy from the sun's rays to preform photosynthesis. After preforming photosynthesis, the plants release Oxygen, which is then

Populations, Communities, and Ecosystems Populations are species in a community. Communities are groups of species that live together. Ecosystems are communities and non-living things in an area. In this image, we can see many populations represented, like the horse population, the llama population, the cow population, the pig population, the
Physics
Archimedes was a Greek mathematician, physicist, engineer, astronomer, and inventor who lived in the third century BC. He is well known for predicting the use of calculus, and discovering an approximation of pi. While he was in Syracuse, the city was attacked by Rome in the years 213 and 212
Biology
Every animal and plant needs food for energy. Plants get food by making it themselves, but humans and animals have to find food. Food is used in the human body as both energy and building blocks. Large molecules of food that contain mostly oxygen, hydrogen, and carbon are broken down
Biology
Photosynthesis is the process by which an organism makes its own food. Some organisms that can do this are algae and plants. The main factor in photosynthesis is sunlight. The other two components of photosynthesis are water and carbon dioxide. The energy from the sunlight is used to break down
