1. Cite evidence to support the statement that, "No matter how many parts of an object are assembled, the mass of the whole object made is always the same as the sum of the parts."
|
|
|
|
a. Use magnifying instruments to investigate samples of matter, such as a leaf, sugar cube, color photograph, and granite to describe the minute parts from which they are made.
|
|
|
|
b. Use evidence from investigations with a variety of materials, such as water to describe how matter can change from one form to another without the loss of any mass.
|
|
|
|
c. Describe the relationship between the masses of whole objects to the sum of the mass of their parts using appropriate tools to gather supporting data.

1. Provide evidence from investigations to identify the processes that can be used to change materials from one state of matter to another.
|
1. Provide evidence and examples illustrating that many substances can exist as a solid, liquid, or gas depending on temperature.
|
|
|
a. Observe and describe the changes heating and cooling cause to the different states in which water exists.
- Heating causes: ice (solid) to melt forming liquid water; liquid water to evaporate forming water vapor (gas).
- Cooling causes: liquid water to freeze forming ice (solid); water vapor (gas) to form liquid water.
|
a. Use evidence from investigations to describe the effect that adding heat energy to different types of matter has on changing matter from one state to another.
|
|
|
b. Based on data explain the importance of water's ability to exist in all three states within the temperatures normally found on Earth.
|
b. Based on data from investigations describe the effect that removing heat energy from different types of matter has on changing matter from one state to another.
|
|
|
c. Analyze data from observations to support the idea that when materials change from one state to another the amount of material stays the same.
|
c. Analyze data gathered and formulate a conclusion on the effects of temperature change on most substances.

1. Provide evidence to illustrate that when a new material is made by combining two or more materials, its properties are different from the original materials.
|
1. Cite evidence to support the fact that some substances can be separated into the original substances from which they were made.
|
|
|
a. Investigate and describe what happens to the properties of materials when several materials are combined to make a mixture, such as table salt and pepper; various kinds of nuts, chocolate pieces, and coconut; sugar dissolved in milk
|
a. Investigate and identify ways to describe and classify mixtures using the observable and measurable properties of their components.
|
|
|
b. Based on observations from investigations and video technology, describe what happens to the observable properties of materials when several materials are combined to make a new material, such as baking soda combined with vinegar
|
b. Based on data gathered, identify and describe various processes used to separate mixtures.
|
|
|
c. Share data gathered and construct a reasonable explanation of the results.
|
c. Use data gathered to provide a reasonable explanation for the idea that the mass of a mixture is equal to the sum of the masses of its components.
