Food Web

In my food web the sun provides the energy needed to run the process.
Lettuce is my producer.  It provides it's own food.  I picked lettuce to by my producer because it is eaten by a wide variety of animals.
Consumers do not produce their own food.  My primary consumers are mice, crickets, and groundhogs.  My secondary consumers are foxes, snakes, bobcats and owls.
My top predators are owls and bobcats.  A top predator is not eaten by any other animals.

Food Web

A food web always begins with the sun because it produces energy for all plants.  The small plants are producers, meaning it makes it's own food.  Then the fish eats the plants, leaving the fish an omnivore.  An omnivore eats plants and animals.  Next, the penguin eats the fish and is eaten by a Leopard Seal.  They are both carnivores, which means they only eat meat.  The Orca, who is also a carnivore, eats the penguin as well as the Leopard Seal.  This method will repeat itself over and over again.

Fractions

Fractions

There are three types of fractions.  The proper fraction has the smallest number on the top and the large number on the bottom.  There is another type of fraction called improper fraction.  In this case the large number is the numerator and the smallest is the denominator.  And the last one, a mixed fraction is a whole number and a proper fraction combined.

You change an improper fraction to a mixed fraction by dividing the numerator by denominator.  The quotient needs to be the whole number and the remainder is the new numerator.  And the denominator stays the same.

If you want to change a mixed fraction to a proper fraction you multiply the denominator by the whole number and add the numerator.  Then write your answer.  The total when you add the whole number to the numerator goes on the top and the denominator stays the same.

Solar System Model

 

In my class we are studying the Solar System.  I was very interested in the planets and decided to create my own model of the Solar System.
