Seventh Grade Bundles

Matter & Its Interactions

Pure substances have identifying characteristics that are used to identify them. Using models, students should comprehend that substances are made from different type of atoms and that atoms form molecules ranging from small to very complex structures. If a chemical reaction occurs, the parts that make up the original substance is regrouped in a new way that makes a new substance with new properties. The students’ understanding should increase as they work with models to know that if atoms are rearranged, that the ending result is a different substance.  

 

Includes: MS-PS1-1, MS-PS1-2

Energy

Students will understand kinetic energy within a system. Energy is neither lost nor destroyed so that when energy in an object appears to leave the system, it actually is transferred to another object within a given system at the same time. 

 

Includes: MS-PS3-6

Biological Unity & Diversity

Within every population, there are variations of organisms. Some of these variations exhibit traits and behaviors that will favor the chance to survive and reproduce, while others will decrease the likelihood to survive and reproduce. Through technology, humans have found ways to enhance the rate at which some beneficial traits in some organisms occur. 

 

Includes: MS-LS1-4, MS-LS1-5, MS-LS4-4, MS-LS4-5, MS-LS4-6

 

Heredity

Within this bundle, students learn the difference between sexual and asexual reproduction. Sexual Reproduction is the production of new living organisms by combining genetic information from two individuals of different types (sexes). Genetic information is transferred to the offspring through egg and sperm cells. Variations of those inherited traits between the parent and offspring arise from those genetic differences. Using a Punnett square to show those differences would be beneficial. In asexual reproduction, the offspring results in identical genetic information. 

 

Includes: MS-LS3-1, MS-LS3-2, MS-LS4-3

Sensory Receptors

In response to environmental stimuli, signals are transmitted along nerve cells to the brain, which are then processed by the brain. The brain then produces memories and/or behaviors as a result of the processed stimuli. Students should be able to understand this process and explain that memories or behaviors are a result of sensory receptors responding to environmental stimuli by sending messages to the brain.

 

Includes: MS-LS1-8

 

 

Earth's Place in the Universe

Patterns in the motion of objects in the solar system can be observed, described, predicted and explained. These patterns are responsible for seasons, tides, eclipses, moon phases, day and night, and the apparent relative motion of objects in the sky. Even though the planets, moons, and the sun are vastly different in size and scale, each has its own gravity, which acts on all these objects. The sun’s gravity keeps all planets in a predictable orbit around it. The gravitational force of Earth acting on objects near Earth’s surface pulls objects toward the planet’s center.

 

Includes: MS-ESS1-1, MS-ESS1-2, MS-ESS1-3, MS-PS2-4

 

 

 

Weather & Climate

Weather can change in a short amount of time and factors such as, air pressure, temperature, humidity, precipitation, and wind can cause those changes. Weather can be predicted, but weather forecasting has not been perfected. Data from weather maps, diagrams, and other visualizations can be used to detect and predict weather patterns. The sun drives all weather patterns on Earth. Ocean currents can redistribute energy from the sun, which can affect regional climates. Your location on the planet (i.e. Latitude and longitude) will determine the weather and climate experienced. Large bodies of water can also affect the weather patterns in a given area.

 

Includes: MS-ESS2-5, MS-ESS2-6
