S&EP Test Regrade 8/25/27

Question #1:  In science class, a group of students builds prototype for a magnetic levitation train and then use it to explain how forces interact to keep the train elevated.
Correct Answer: Developing and Using Models

I understand that this is the correct answer because the group of students created a prototype for a magnetic levitation train. This is their model so that they can explain how forces interact. They created a model to understand and explain their idea.




Question #2: A group of 7th graders creates and analyzes graphs of the data from an investigation about the relationship between a ball's mass and its speed down a ramp.

Correct Answer: Using Mathematics and Computational Thinking

I know this is the correct answer because the group of 7th graders needed to analyze graphs of the data with mathematics and computational thinking to figure out the relationship between a ball's mass and its speed down a ramp. Mathematics and computational thinking is used for statistically analyzing data.




Question #4: After wondering about how the size of a magnet affects the number of paperclips it can pick up, a group of students develops a procedure that answers their question. They gather data and report back to the class.

Correct Answer: Planning and Carrying out investigations

I know that this is the correct answer because the students planned and developed a procedure that answers the question. They planned and carried out the investigation, or in their case, a procedure that answers their question.

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 vibrate, mak

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

Plant and Animal Adaptations (10/17-10/21)

Adaptations are things that help all living things be able to reach their ultimate goal. The ultimate goal for all living things is to survive to reproduce. There are things that animals and plants need to survive. Animals need: food water shelter air Plants need: sunlight water food air All living things change over time so it is easier for them to fit in their environment. For example, when wolves started being tamed, and allowed in houses, they started to change into dogs. Their teeth are not fit for hunting animals, or breaking them apart to eat. There are more things, but I have more to talk about. Do people ever tell you that you have the same eyes as your mom, or the same nose as your dad? Adaptations are inherited characteristics that help organisms survive long enough to reproduce. What
