Matter and Its Interactions

1 ) Plan and carry out investigations to provide evidence that matter is made of particles too
small to be seen.


2 ) Investigate matter to provide mathematical evidence, including graphs, to show that regardless of the type of reaction or change that occurs when heating, cooling, or mixing substances, the total weight of the matter is conserved.


3 ) Examine matter through observations and measurements to identify materials  based on their properties.


4 ) Investigate whether the mixing of two or more substances results in new substances.


5 ) Construct explanations from observations to determine how the density of an object affects whether the object sinks or floats when placed in a liquid.


Motion and Stability: Forces and Interactions

6 ) Construct an explanation from evidence to illustrate that the gravitational force exerted by Earth on objects is directed downward towards the center of Earth.


7 ) Design and conduct a test to modify the speed of a falling object due to gravity.


Ecosystems: Interactions, Energy, and Dynamics

8 ) Defend the position that plants obtain materials needed for growth primarily from air and water.


9 ) Construct an illustration to explain how plants use light energy to convert carbon dioxide and water into a storable fuel, carbohydrates, and a waste product, oxygen, during the process of photosynthesis.


10 ) Construct and interpret models to explain that energy in animals' food is used for body repair, growth, motion, and maintenance of body warmth and was once energy from the sun.


11 ) Create a model to illustrate the transfer of matter among producers; consumers, including scavengers and decomposers; and the environment.


Earth's Place in the Universe

12 ) Defend the claim that one factor determining the apparent brightness of the sun compared to other stars is the relative distance from Earth.


13 ) Analyze data and represent with graphs to reveal patterns of daily changes in length and direction of shadows, day and night, and the seasonal appearance of some stars in the night sky.


Earth's Systems

14 ) Use a model to represent how any two systems, specifically the atmosphere, biosphere, geosphere, and/or hydrosphere, interact and support life.

15 ) Identify the distribution of freshwater and salt water on Earth and construct a graphical representation depicting the amounts and percentages found in different reservoirs.


Earth and Human Activity

16 ) Collect and organize scientific ideas that individuals and communities can use to protect Earth's natural resources and its environment.


17 ) Design solutions, test, and revise a process for cleaning a polluted environment.
