  1. 1.  The mass of an atom consists of: Nucleus › Electrons- negative charge › Neutrons- neutral charge › Protons- positive charge Nucleus is made protons and neutrons Electrons orbit the Electrons nucleus
  2. 2.  Biology is the study of life and living organisms. › Plant and animal life › Structure and functions of living things › Classification › Life Cycles › Origin and Evolution through time › Reproduction
  3. 3.  Chemistry refers to:  The study of matter.  How atoms interact with other atoms.  How chemical bonds are formed.  The physical properties of matter.  Changes from one state of matter to another (ex. solid to gas).  Matter is organized by elements in the periodic table (see picture to the left).
  4. 4.  Discover is defined as „to make known or visible‟. Knowledge is constructed when students are provided the opportunity to discover the expected content or lesson. Science must be taught as an active process-as something we do. Science experiments allow for such discovery to occur within the classroom.
  5. 5.  States of energy: › Kinetic-energy due to motion › Potential-stored energy Forms: › Activation-the energy › Heat necessary to transfer or convert potential › Light energy into kinetic › Solar radiation energy. › Chemical  When kinetic energy is › Electrical greatest, potential energy is lowest. › Magnetic  Conservation of energy- › Sound The total energy within a › Mechanical closed system remains the same. Energy can not be created or destroyed, only changed from one form to another.

  7. 7.  Geology is the study of  Layers of the Earth: solid Earth, the rocks of › Crust-the outer portion which it is composed, of the Earth. It varies and the processes by from 3 miles to 40 miles which it evolves . thick. › Mantle-thickest layer of the Earth. It is located below the crust. It is made of mostly rocks and metals. Magma is formed in this layer. › Core-inner part of Earth. Solid inner core consists of iron and nickel and a liquid outer core.
  8. 8.  Human body has many systems › Immune System-defends against to help it function: foreign proteins and infectious › Musculoskeletal System-The organisms. human skeleton consists of more than 200 bones held together by connective tissues called ligaments. Skeletal muscles allow for movement of › Respiratory System-takes in bones. (2) oxygen by expanding the lungs. When the lungs contract, › Nervous system- carbon dioxide is released.

It then cycles back through meiosis. through the heart. (9)
  9. 9.  Inquiry model known as the learning cycle consist of three phases: Engage › Exploration › Concept invention › Application Evolved into the 5-E model › Engage-gain student‟s attention. Elaborate EVALUATION Explore › Explore-Student-centered, hands-on activity. › Explain-students present and share information with classmates. › Elaborate-students use the new concept they learned as it is Explain applied to new contexts. › Evaluate-the teacher uses authentic ways to measure learning in each phase.
  10. 10.  A journal is a scientific tool used to record data. Observations result in various findings that must be recorded for use in future experiments. Scientists use a journal to record sights, sounds, smells, textures, speed, mass, or temperature of outcomes from experiments. Scientists might also use journals to record predictions of possible outcomes to refer to after a test has been conducted.
  11. 11.  Knowledge is defined „as the acquaintance with facts, truths, or principles, as from study or investigation‟. It is best constructed though hands-on activities that engage the mind and link to new ideas to prior knowledge. (4)
  12. 12.  Life cycle of plants begins with a seed. Seeds begin to grow roots which extend through the soil. The roots allow for the plant to gather water and nutrients for the plant to sprout. The leaves that grow above the ground capture energy from the sun and convert it to chemical energy through a process called photosynthesis. A tree sprout becomes a sapling as it continues to grow. Once the tree matures, it may produce fruit or flowers that generate more seeds. Seeds are then planted into the soil to cause the life cycle of another tree. (10)
  13. 13.  Matter is defined as anything  Three different states of that has mass or takes up matter: space. › Solid- Properties of matter: › Physical-Color, density, hardness, and conductivity › Thermal-sensitive to temp › Liquid- changes › Electrical- acts as a conductor or nonconductor of electrical current › Chemical-chemical properties of matter will › Gas- react with properties of different types of matter. It will not react with the same type of matter.
  14. 14.  The common basic needs of all living things are air, water, food, and shelter. Living organisms need nutrients, the appropriate temperature, and a balanced ecosystem to survive and reproduce. The sun provides energy for plants; plants are consumed by animals, animals are consumed by other animals. When animals die, they become food sources for plants. An ecosystem must be balanced to exist. If it is disrupted by nonnative species or removal of organisms, animals and plants will either die or they must adapt to the change to survive.
  15. 15.  Observation is a key part of how science it developed. We study and observe other living things to learn about their manner of survival. We observe how elements react to each other to create new man-made elements. Such creations might lead to a cure for what are now considered incurable diseases.
  16. 16.  The moon completes a lunar  New moon (11)  Half moon (13) orbit around Earth in about 28 days. The moon‟s visibility from Earth is categorized in phases based on how much of the surface of the moon we can see.  Crescent moon › New Moon- no moon can (12)  Gibbous Moon (14) be seen in the sky. › Crescent moon- the shape of the moon is often compared to a banana. › Half moon-only half of the  Full Moon moon is visible. › Gibbous moon-3/4 of the moon can be seen. › Full moon- the whole moon is visible.

These answers will be recorded and distributed to fellow scientists and people around the world.

In this process, the cell another cell with the same DNA. divides twice causing the genetic This process is also referred to as material to divide in half. When asexual reproduction since no genetic materials from a male exchange of genetic material and female species combine, the occurs. Each offspring is identical DNA material from both cells join to the parent cell. (15) creating a new life form. This process is also referred to as sexual reproduction. It requires DNA from two organisms of the same species to create a new organism. (16)

  21. 21.  A synonym for understanding is comprehension. The most effective method to develop understanding for the student is to develop their science thinking skills. Table 4.1on page 265 of the TExES book lists all the steps necessary to develop understanding in the field of science.
