Seasons
In the spring, leaves start to grow on the trees. In the summer the tree are filled out with their leaves. In the fall the leaves fall off of the tree and leaves change color. In the winter no leaves or few leaves are on the tree.

Benjamin Banneker
Benjamin
Banneker was born in 1731, [in] Maryland, America. When Benjamin Banneker was a boy he studied
math and a pocket watch.
Benjamin helped people by [making] a clock and it told the
weather [and] the seasons. Benjamin helped
by [making] the Almanac because it told them when to plant. Benjamin studied a watch and their parts like
the inside and the outside of the watch.
Benjamin knew stuff like multiplication, adding and subtracting and he
knew more than his teacher. Farming in
the past was done by hand and not tractors or farm machines.
Benjamin Banneker’s inventions [are] important because we
can tell time now!

George Washington Carver
George Washington Carver was born in Missouri [in]
1861. He studied plants and
farming. George studied even more about
plants.
He made
peanuts [into] peanut butter, ice cream, paper, ink, shaving cream, and
shampoo. George found that he could make
118 different products from sweet potato.
These included soap, coffee, and glue.
That he made over 300 different products from peanuts. George knew so much about plants that the
people called him the plant doctor.
[If] George Washington Carver did not make shampoo we could
not wash our hair.

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.

Measuring Capacity
The "G" stands for gallon, "Q" for quarts, "P" for pints, "C" for cups and little dots for ounces. This is good to go back and look to remember the gallon.

El Sistema Solar
El Sistema Solar
El Sistema Solar se compone de
objetos como asteroides, planetas, el Sol, meteoritos, órbitas, y cinturón de asteroides.
Un planeta está hecho de masa y
gases. También está hecho de rocas que
orbitan alrededor del Sistema Solar.
Una órbita es donde los planetas
rotan alrededor del Sol. Porque si no
van en una órbita chocan.
El Sol es una bola gigante de
gases, y los planetas rotan alrededor del Sol.
El Sol también es brillante como una estrella.
El cinturón de asteroides es un
grupo de rocas juntas en medio de Marte y Jupiter también se le puede llamar que
está entre medio de los planetas interiores y exteriores.
Los planetas interiores son frÃos,
pequeños, y rocosos. Los planetas exteriores
son grandes, gaseosos, y tienen color.
The Solar System
The Solar System consists of objects like asteroids, planets, the
Sun, meteors, orbits, and asteroid belt.
A planet is made of mass
and gases. Also it’s made of rocks that orbit the solar system.
An orbit is where the planets rotate around
the sun. Because if
they are not in an orbit, they will collide.
The Sun is a giant ball of gas, and planets
rotate around the sun. The Sun is also a shining star.
The asteroid belt is a group of rocks together in the
middle of Mars and Jupiter. Also you
can say it is between the interior
and exterior planets.
The interior planets are cold, small and rocky.
The exterior planets
are large, gaseous, and have color.

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.
