  School Hours

Student Attendance: 9:00 - 3:30


Students/parents; find weekly assignments under newsletter section! As fourth graders I feel the students should be learning responsibility with their assignment notebook. Therefore, they are responsible for writing down their assignments and gathering their materials at the end of the day. I will not be checking and signing everyone's notebook. If you feel your child needs help with their organization, please contact me. John Buchanan Arbury Hills Elementary School 19651 Beechnut Drive Mokena, IL 60448 708 479-2106

Dear Students & Parents:

Welcome to fourth grade; I look forward to working with you!

ELA: Readworks has many great summer reads.

You can access them for free at

Give it a try; it's free!
***All students are expected to know all their facts when entering 4th grade! That includes addition, subtraction, and multiplication! Make it a part of your summer routine to practice daily for 10-15 minutes! 

Social Studies: 

Summary: The Lewis and Clark Expedition consisted of a select group of military men, called the Corps of Discovery and civilians, led by Captain Meriwether Lewis and Second Lieutenant William Clark to explore the US lands obtained in the 1803 Louisiana Purchase and the Pacific Northwest. The purpose of the expedition was both scientific (creating maps and documenting plants and animals) and commercial (establishing trade and identifying natural resources). They were helped by a female Shoshone guide called Sacajawea. The Lewis and Clark Expedition traveled along the Missouri River from St. Louis to the mouth of the Columbia River. The Lewis and Clark Expedition started on May 21, 1804 and ended on September 23, 1806.

Science: The English naturalist Charles Darwin realized over 150 years ago that physical features (structures) and how they are used (functions) took many generations to develop. He observed that those species of animals and plants that were able to survive and reproduce were those that had best adapted to the challenges of their environments. He called this process through which adaptation occurs “natural selection.Plants - In the rain forest with its heavy green foliage, the competition is not for water, but for sunlight and space. As a result, plants in rainforests grow taller and faster than neighboring plants to reach the sunlight. Those plants that are in deep shade areas will have darker green and red leaves to absorb as much light as possible. In Arctic regions, although there is plenty of sunlight during the summer, the wind blows unmercifully over the unprotected landscape. As a result, trees grow very low to the ground, sometimes no more than a few inches tall, to avoid the howling wind. The plants are also smaller than similar species at lower latitudes because of a shorter growing season farther north.Plants release moisture through their leaves. However, in the desert where water is scarce, leaves in plants like cacti have evolved to resemble sharp spines to protect the plant from loss of the water stored inside their stems. No transpiration occurs through the spines and photosynthesis is done in the stems of the cacti. Cacti can store gallons of water in their stems to be used sparingly during periods of no rain. Desert plants have roots that spread wide and extend deep into the ground to capture every valuable drop of water. Even a houseplant, when placed near sunlight, will grow toward the light source. Every part of a plant, root, stem or trunk, leaf, flower or fruit is vital to the survival of the plant.Students explore the relatively simple three-stage life cycle of plants, such as the radish and the lima bean. These plants change from seed to seedling, and finally to an adult plant with flowers that contain the seeds of the next generation. A plant sometimes protects its seed by encasing it in either a hard shell like a walnut or a soft, fleshy covering like a peach. When the walnut or peach falls from the tree, this protection gives the little seed a chance to begin to grow. Some plants use flowers to attract birds or insects in order to cause these creatures to carry their pollen to other plants for fertilization. In all cases, when the seed falls to the ground and is fortunate enough to settle into good soil, it will begin to grow into a seedling and the life cycle will be repeated. Animals - Animals are products of their environments as they must adapt to their environment or die. Many animals that live in an aquatic environment have webbed feet to aid swimming both in cold and warm water. Many waterfowl, such as ducks and geese, have webbed feet. Other animals, such as polar bears and otters, have webbed feet as well. The flaps of skin between the toes of webbed feet allow the animal to push against the water with greater force for faster swimming to catch food or to escape from predators. Sharp claws are a structure of many animals that need running speed, climbing ability, digging prowess, or hunting skills. Hooves on horses and antelopes allow them to run faster and more easily over hard prairie ground. A hoof is simply one large, modified toenail that supports the entire foot and leg. The sucker-like feet on a Gecko lizard allow it to cling to objects to hide from predators or to wait for food. The grasping feet of tree monkeys allow them to swing from limb to limb. Flippers on penguins and seals are structures that allow these animals to swim rapidly, either to find food or to escape a predator. The strong back legs of rabbits, kangaroos, and cheetahs allow the animals to leap and run long distances, either to escape predators or to catch prey. An animal’s teeth often indicate its source of food. Sharp teeth reveal a carnivore (meat eater), while broad, flat teeth for grinding food belong to an herbivore (plant eater). The beaks of birds vary according to diet. The crane has a long, narrow beak to reach deep into water for small fish, while a finch has a short, powerful beak for cracking nuts and seeds.Predators like eagles and hawks have curved, sharp beaks for tearing chunks of flesh from their prey. By having a color or shape which blends with the environment (camouflage), the organism is better able to hide from its enemies and stalk its prey. A lizard can change skin color to blend in with its environment. A baby deer has spots to hide it from predators. An arctic hare is white to blend in with the snow covered terrain. Sometimes an animal resembles another organism or its surrounding to better survive (mimicry). Some insects look like leaves, while other insects resemble a stick to hide themselves. The Dragon Seahorse resembles a leafy aquatic plant in order to hide from predators. Some animals try to appear larger to scare off predators like a cat arching its back. In the frigid regions of the North or South Poles, animals like the Polar Bear or seals have thick layers of blubber underneath thick skins to protect them from the ice and freezing water. In hot desert environments animals can be small, like the kangaroo mouse, or have thick skins, like scorpions, to prevent water loss.
