Math Strategist
I have finally completed the Math Lab, done all without air-conditioning. I am scheduled to run a pilot group of student through this week. The lab features the Promethean Board and hands-on-activities releated to this 9 week TEKS. I hope to have a schedule posted for all classes to sign up soon.

Tigers
Tigers are not only related to lions, cougars, and jaguars- they are related to other wild cats. Tigers have black stripes and some have white stripes. Some tigers are black and white. They have sharp teeth and sharp claws.

Frogs
First frogs turn in to baby tadpoles. Then they grow when they eat. Then when they’re done with tadpoles, they
turn in to kids. Then when they’re done
with kids, they turn in to adults. That’s
how frogs grow. The end.

The Planets
Mercury is the closest planet to the Sun and the eighth
largest. It is many ways similar to the
moon because its surface is cratered and very old.
Venus is close to earth.
Its clouds reflect sunlight so it appears to be the brightest planet in
the sky.
Earth is an ocean planet, home of water and life. It is the third planet from the sun.
Mars is a cold, desert world. It is half the diameter of Earth and has the
same amount of dry land like Earth.
Jupiter is the most massive planet in our Solar System with
four large moons.
Saturn is made mostly of hydrogen and helium. It is the sixth planet from the Sun.
Uranus is the seventh planet from the Sun. It is one of the two ice giants of the outer
solar system.
Neptune is the ice giant.
Neptune was the first planet located through observation in the sky.
Pluto is much smaller than any of the official planets and
is now known as a “dwarf planet.”

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.
