Atoms contain three types of subatomic particles: protons, which have a positive charge; neutrons, which have a neutral charge; and electrons, which have a negative charge. Electrons orbit the nucleus at extremely high speeds.
Water consists of a chemical compound formed between two hydrogen atoms and one oxygen atom. The atoms are connected to one another via a covalent bond.
Join an American Indian Interpreter as they share how the founding fathers looked to native governments when establishing their new republic.
In this optics activity, learners examine how polarized light can reveal stress patterns in clear plastic. Learners place a fork between two pieces of polarizing material and induce stress by squeezing the tines together. Learners will observe the colored stress pattern in the image of the plastic that is projected onto a screen using an overhead projector. Learners rotate one of the polarizing filters to explore which orientations give the most dramatic color effects. This activity can be related to bones, as bones develop stress patterns from the loads imposed upon them every day.
A ball and socket joint is made of a bone with a rounded end that fits inside a cup-like pocket of another bone, enabling bones to move in a circle. Hip joints and shoulder joints are examples.
Periosteum is a membrane that covers bones and plays a role in bone growth and repair. Beneath the periosteum is compact bone.
The skull protects the brain.
The heart consists of cardiac muscle.
Cartilage is a flexible tissue that covers the ends of many bones.
The circulatory system is composed of the heart, blood vessels, and other structures.
Gliding joints enable movement from side to side.
Ligaments are tough, band-like tissues that attach bones to each other.
Each muscle fiber in the body is a single, cylinder shaped cell.
Red marrow is extremely important in producing red blood cells.
The skeletal system, made up of bones and the materials that connect them, is the body's framework.
Depicts bones in the skull, which are attached to one another by immovable joints.
Smooth muscles are involuntary muscles. They can contract without us thinking about it. The bladder and intestines contain smooth muscle.
The knobs at the end of many bones are made of spongy bone, which contain many spaces.
This resource is a Nearpod lesson about the Bonney Butte HawkWatch site located in the Mt. Hood National Forest in Oregon. It was created as part of the Reimagine Teaching program by HawkWatch International. HawkWatch International is a non-profit organization in Salt Lake City, Utah that works to protect raptors and our shared environment through scientific research and public education.
The Great Salt Lake (GSL) is drying up and molecular biologist Bonnie Baxter’s message is the harbinger of environmental devastation to come. Her unprecedented research of the lake's two major food chains, brine shrimp and brine flies, shows that both are on the brink of collapse due to increased salinization as lake shorelines recede.
