Assignment Space Exploration Time Line Presentation
Total Score: of 60 points
For the presentation you will research and provide summaries for manned and unmanned explorations of your choice. The presentation should be about twelve slides in length. Your presentation will include:
• Title
• Introduction – gives an overview of the presentation
• Time line of missions – must include 3 manned and 3 unmanned missions
• Description of each of the missions in the timeline (1 mission per slide)
(a) Name and date of mission
(b) Purpose of missions
(c) Results or findings from missions
• Scientific advance – describe a scientific advancement that has led to an engineering improvement in space exploration
• Engineering advance – describe an engineering advance that has led to greater knowledge about the solar system
• Sources – list the websites and other sources you used
Remember to make a list (i. e., bullet points) on each slide. The slides should feature the highlights of the main idea. The bullet points should be short phrases (at most, one sentence) that highlight key points.

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
