Certain crisis can affect the safety of the food you serve. Garbage container which is also known as a waste …. An imminent health hazard is a significant threat or danger to health that requires immediate correction or closure to prevent injury. This can result in the growth of pathogens.

So, let's talk about human population growth. How much does the population size vary? NGSS Life Science offers many great lessons. Using their clicker, they select from the following answer choices: A) site two has a greater abundance and density than site one; B) site one has a lower abundance but equal density to site two; C) site one has a lower abundance but greater density than site two; or D) the density and abundance are equal for both sites (Supporting File S1: Lesson Presentation Slides with Instructor Notes, slides 7-8).

Population Growth Worksheet Answer Key

Students were assessed using formative and summative questions aligned with the learning outcomes: quantifying population size, plotting and predicting population growth, calculating growth rate, and incorporating carrying capacity in logistic growth curves. Vocabulary/Definitions. Instructors will also benefit from basic knowledge about barnacles and the intertidal zone. What are some of the factors that have allowed for exponential human population growth? How would you describe human population growth in the next 5, 000 years represented in the graph? Much of this ability is related to human intelligence, society, and communication. This two and a half minute clip leads to great conversations about our growing human population. The activity takes a biological system and describes it as a mathematical process with manipulatable variables. STUDENT PERFORMANCE AND CONCEPTUAL DIFFICULTIES. The contents of this digital library curriculum were developed through the Bio-Inspired Technology and Systems (BITS) research experience for teachers program under National Science Foundation RET grant no. Speth EB, Momsen JL, Moyerbrailean GA, Ebert-May D, Long TM, Wyse S, Linton D. 2010.

Activity 1 - Modelling population growth. Wars between powerful nations, Pandemics, over population that is until new technology was invented that raised the population barrier, I forgot what the exact name is. Earth's human population is growing rapidly, to the extent that some worry about the ability of the earth's environment to sustain this population, as long-term exponential growth carries the potential risks of famine, disease, and large-scale death. Comparing Human Population Trends. Link to this Scatch project on the MIT site). The worksheet attached to this activity takes students through an introductory activity, but more is possible and this can be adapted to suit a class. While the growth rate has dropped from around 2. Many choose to have only one child, or none at all. Students observe a diagram and compare the density and abundance of barnacles. After discussing regulating mechanisms, the instructor shows students the logistic growth equation (Supporting File S1: Lesson Presentation Slides with Instructor Notes, slide 25).

We also suggest that instructors familiarize themselves with common and persistent conceptual difficulties related to population growth. Pre/post-test questions are included in Supporting File S4: Pre/Post-Test Questions and Student Responses. Overpopulation in The Gambia (Youthful populations) 5. The age structure of a population allows us to predict population growth. For example, beaver dams alter the stream environment where they are built.

Nie wieder prokastinieren mit unseren kostenlos anmelden. 4) At about 200 years BP to present, there's a very significant population explosion. Education Standards. The impact of microcomputer-based labs on children's ability to interpret graphs. Remind them to read all instructions carefully. If desired, the instructor can write these answers on a board and identify biotic versus abiotic factors. Sign up to highlight and take notes. To calculate the normalized gain for overall scores on the pre/post-test, we used the following formula (31): (% of students who scored correct on the post-test -% of students who scored correct on the pre-test) / (100% -% of students who scored correct on the pre-test). Earn points, unlock badges and level up while studying. Note: Before class, complete the following: 1) use the internet to obtain a reasonably accurate figure for the current human population of our planet, such as the U. S. Census Bureau's population clock at, and 2) write the following question on the board: "About how many people are on the Earth today? The instructor first introduces density and abundance, explaining that the choice of using density or abundance depends on the organism and study design (Supporting File S1: Lesson Presentation Slides with Instructor Notes, slide 6). In addition, because the available instructional materials on this topic are largely computer models and lab based activities, there is a need for tools that integrate quantitative skills in a lecture format. How systems, living or not, function often depends on many different factors. They have also incorrectly explained that competition only occurs between organisms of the same species (11, 12).

While there have been many controversial methods proposed to control the human population, many humane methods have been proposed. Source: United Nations Population Division. The activity makes extensive use of the publically available: World Population Prospects, 2015 Revision, Volume II: Demographic Profiles, United Nations, This publication contains demographic data for a considerable number of other countries that could be used to expand the activity. This is known as the Toba catastrophe theory. Sexual equality on a global scale has also been proposed as an effective method, since this lessens the regulations of traditional gender roles and allows a greater number of women to enter the workforce, rather than being pressured to remain at home raising children. The normalized change for the pre/post-test is =0. PRE-CLASS PREPARATION.

Human Population Growth Activity Answers

A constant slow increase with very little risk, vs a very large fast increase with a larger risk. Two pre/post-test questions (PPTQ4 and PPTQ5) asked students to determine how growth rate changes over time in exponential and logistic growth curves (Table 2, Supporting File S4: Pre/Post-Test Questions and Student Responses). Some students may draw curves onto graphs of similar shape to those produced during the activity, but with the carrying capacity from the question, not from something they did during the activity. Student performance increased following peer discussion of clicker questions and on post-test questions. For example, the instructor can highlight looking at the y-axis to determine if abundance or density is measured, the importance of considering population size and rate of growth separately, and the role of carrying capacity in producing the logistic growth curve. Mokros JR, Tinker RF.

Ask some leading questions. ) We also calculated normalized gain scores (31) at the individual question level and found a range from =0. Another zone is at around 900 to 500 years ago. Growth Patterns: Put a few example graphs on the board, some of which show unusual or "impossible" patterns (such as a graph in which the population is larger than the actual size of an average Petri dish, and a graph that shows the population is declining below zero; see Figures 1 and 2) and some of which show standard logistic growth curves. This latest movement in growth compared to earlier times, has been astronomical. What does it mean when r=1, or the intrinsic growth is 1?

As the density of individuals in a population increases, these individuals must begin competing for limited resources with each other (same species, or intra-specific competition) or with other species (inter-specific competition). The instructor can then request that students notice that the second part of the equation including K is (1-N/K). This is true for all animal species, human and non-human alike. The instructor first defines growth rate and then describes how it differs for the three growth curves (linear, exponential, and logistic), showing, but not yet explaining, the three mathematical equations (Supporting File S1: Lesson Presentation Slides with Instructor Notes, slide 17). An introduction to population ecology.. Accessed September 24, 2016. MAA-CIE Cooperative News. 100, 000-300, 000 people. Begin by making r=1. Be perfectly prepared on time with an individual plan. Experts would generally approach these questions by calculating density [density (D)= number of individuals (n) / unit volume (v)], and counting the number of individuals for abundance. I use this cartoon as an introduction and have students read it for bell work before we take notes on logistic and exponential growth, and carrying capacity. To provide students with the opportunity to think about the x-and y-axes on the graph, and also how barnacle populations might grow over time, the instructor next asks students to predict barnacle population size over the course of the experiment (Supporting File S1: Lesson Presentation Slides with Instructor Notes, slide 12).. TPSQ2. For approximately four minutes, students brainstorm in small groups and write (on their worksheet) the factors that they think might affect barnacle population size (Supporting File S1: Lesson Presentation Slides with Instructor Notes, slide 4). SYNTHESIS (~7 MINUTES).
Proceedings of the 9(th) Annual ACM International Computing Education Research Conference, San Diego, CA. The growth rate (or change in the population density) is: Students use a diagram of the three different growth curves (linear, exponential, and logistic) and infer how the growth rate is changing over time in each. There is no mention of immigration or emigration in these activities, and these terms are listed in the IB guide. It is important to note that simplified population models such as the Ricker model are extremely valuable for understanding and learning ecological processes involved in population dynamics.
