Dinosaur Success - Weekly Blog (11/5-11/9)

Physical Features of Dinosaurs by Australian Museum

Summary

There are many factors that contributed to dinosaur success. Many of their physical features helped dinosaurs thrive for about 165 million years. As seen in the image above, the main characteristics shared by dinosaurs include a hole in the skull between eye socket and nostril, two holes in the skull behind the eye socket, an ankle that bends like a hinge, a hip socket with a hole in the middle, limbs held directly under the body, and three or more sacral vertebrae. 

Many of these characteristics are visible in other species. For example, dinosaurs were part of a group called archosaurs. Archosaurs share a hole in the skull. According to the article, 'What Is A Dinosaur?' by Fossil Facts and Finds, "Archosaurs all have a hole, called an antorbital fenestra, between the nasal hole (the Naris) and the eye socket hole (the Orbis.)" As well as archosaurs, dinosaurs were diapsids. Diapsids had two holes behind the eye sockets beside the skull. The holes contributed to dinosaur success because they helped the jaws to open wide and kill prey faster. All dinosaurs had a hip socket that had a hole in the middle. This trait helped support the weight of the body on the leg. Another trait that all dinosaurs shared are limbs that are held directly under the body. This allows for faster movement.

SP8: Obtain, Evaluate, and Communicate Information

This week, I obtained, evaluated, and communicated information about dinosaur traits and success. I researched from various scientific texts to find important. information, evidence, and ideas. I obtained information about the physical characteristics of dinosaurs, and how various shared traits helped make them successful. Next, I evaluated the information I had collected to come up with a hypothesis about dinosaur success. Finally, I communicated the information with others to share my discoveries and learn more about the topic. By obtaining, evaluating, and communicating information, I have learned a lot about dinosaur success and understand the topic more thoroughly. 

XCC: Structure and Function

This week, I observed a structure and function relationship between the structure of the dinosaur and the function. In this relationship, the structure is the structure of a dinosaur. This includes traits and characteristics. The structure then leads to the function of how it helps the dinosaur survive and be successful. For example, the structure that dinosaurs have limbs directly under the body leads to the function that it helps with faster and more efficient movement. However, the structure does limit various functions. For example, having limbs under the body only helps with walking in running, and does not allow various dinosaurs to fly.may not help dinosaurs fly. Understanding this relationship has helped me learn more about how various characteristics have helped dinosaurs become very successful.

Structure of the Periodic Table - 9/25-9/29

In the periodic table, the rows are called periods. Along the rows, the elements are organized by atomic number (the number of protons.) The rows also have the same energy level or the number of electrons. For example, in the first row, all of the elements' atoms have one energy level, and so on.The atomic mass is the number of neutrons plus the number of protons. The atomic mass can be a decimal, and it is ordered increasingly. The columns in the periodic table are called groups or families. Each family has a name. For example, group one is composed of alkali metals which is the family with Lithium, Sodium, and more. Each group also has the same number of outer, or valence electrons. The elements in group one ...

Musical Instruments and Sound- Weekly Blog (3/11-3/15)

Sound Energy - Musical Instruments by SolPass Summary We understand how sound is produced, and how sound waves can travel through different mediums, but how do musical instruments produce sound? There are hundreds of instruments in the world, producing various pitches, tones, and chords. There are three main types of instruments: wind, percussion, and string. The sound is produced differently based on the type of instrument. The first type of instrument is a string instrument. In a string instrument, the sound is created from the vibration of strings. For example, when you play guitar, you pull on the strings. As the strings vibrate, the air molecules start vibrating as well, producing sound. The next type of instruments are wind and brass instruments and are made when we blow sound into them. The shape and position of the instrument affect the overall tone and pitch. The most common kind of wind instrument is a reed instrument. Blowing on the reed causes it to vib...

Energy Transformations - Weekly Blog (1/28-2/1)

Types of Energy  by  Solar Schools Summary: You've probably heard the quote by Albert Einstein, "Energy cannot be created or destroyed, it can only be changed from one form to another." But what are the forms of energy? There are six general energy forms: chemical, mechanical, thermal, light, electrical, and nuclear. Any form of energy can be converted into another form. There are many examples of energy transformations that happen in our everyday lives. The first energy form is chemical energy. Chemical energy is a form of potential energy and is stored in chemical substances. An example of chemical energy is gasoline that is used to power a car. The next form of energy is mechanical energy. Mechanical energy is energy released by a moving object. For example, mechanical energy is the energy that causes a soccer ball to move when kicked. Another form of energy is thermal energy and is associated with the motion of molecules. This means that it is caused by f...
