HELP ME OUT WITH THIS PROJECT PL For this assignment, your teacher will give you an egg and some building materials. You will use these materials to build a device that will keep an egg from cracking when it is dropped from a certain height. Then you will test the device, determine how well it worked, and make recommendations to improve its design. You will present your final design and the logic that supports it in a lab report. Your lab report should include a title, an initial design, observations from your experimental tests, and recommendations for a final design based on force and momentum concepts as well as observations from the tests conducted. To help you write your lab report, there is a Student Worksheet on the last few pages of this document.

Our planet has experienced five major extinctions in the four billion year history of life. the first, 450 million years ago, occurred shortly after the evolution of the first land-based plants and 100 million years after the cambrian explosion. the second extinction occurred 350 million years ago, causing the formation of coal forests. next earth experienced two mass extinctions during the triassic period, between 250 and 200 million years ago. the fifth mass extinction occurred 65 million years ago, ending the reptilian dominance of the earth. according to richard leakey, the sixth mass extinction is happening right now. leakey suggests that we, the human race, are the cause. each year, at our hand, approximately 50,000 species vanish from earth. he believes that man is destroying earth at a rate comparable with the impact of a giant asteroid. leakey's statistics indicate that 50% of earth's species will become extinct within the next 100 years assuming leakey's hypothesis of a sixth mass extinction to be true, how will we expect the model to change? a) a sharp spike in the graph approximately 100 million years from now b) a dip in the graph, followed by a sharp spike about 100 million years from now c) a sharp spike in the graph immediately following the "0" location of the x axis d) a plateau following the "0" mark on the x axis, followed by a gradual rise to a new peak
