Students explore the impact of changing river volumes and different floodplain terrain in experimental trials with table top-sized riverbed models. The models are made using modeling clay in aluminum baking pans placed on a slight incline. Water added "upstream" at different flow rates and to different riverbed configurations simulates different potential flood conditions. Students study flood dynamics as they modify the riverbed with blockages or levees to simulate real-world scenarios.

In a quiet forest in central Florida, a mysterious pond filled with warm clear water hides a secret at the bottom. In this video, Jonathan explores the pond to find a spring which leads into a cave. As Jonathan travels underground, he meets unexpected marine life in the dark depths and learns how water travels through an aquifer from the underground world to the surface. Please see the accompanying study guide for educational objectives and discussion points.

In this lesson, we learn how insects can fly in the rain. The objective is to calculate the impact forces of raindrops on flying mosquitoes. Students will gain experience with using Newton's laws, gathering data from videos and graphs, and most importantly, the utility of making approximations. No calculus will be used in this lesson, but familiarity with torque and force balances is suggested. No calculators will be needed, but students should have pencil and paper to make estimations and, if possible, copies of the graphs provided with the lesson. Between lessons, students are recommended to discuss the assignments with their neighbors.

Samples and ProbabilityType of Unit: ConceptualPrior KnowledgeStudents should be able to:Understand the concept of a ratio.Write ratios as percents.Describe data using measures of center.Display and interpret data in dot plots, histograms, and box plots.Lesson FlowStudents begin to think about probability by considering the relative likelihood of familiar events on the continuum between impossible and certain. Students begin to formalize this understanding of probability. They are introduced to the concept of probability as a measure of likelihood, and how to calculate probability of equally likely events using a ratio. The terms (impossible, certain, etc.) are given numerical values. Next, students compare expected results to actual results by calculating the probability of an event and conducting an experiment. Students explore the probability of outcomes that are not equally likely. They collect data to estimate the experimental probabilities. They use ratio and proportion to predict results for a large number of trials. Students learn about compound events. They use tree diagrams, tables, and systematic lists as tools to find the sample space. They determine the theoretical probability of first independent, and then dependent events. In Lesson 10 students identify a question to investigate for a unit project and submit a proposal. They then complete a Self Check. In Lesson 11, students review the results of the Self Check, solve a related problem, and take a Quiz.Students are introduced to the concept of sampling as a method of determining characteristics of a population. They consider how a sample can be random or biased, and think about methods for randomly sampling a population to ensure that it is representative. In Lesson 13, students collect and analyze data for their unit project. Students begin to apply their knowledge of statistics learned in sixth grade. They determine the typical class score from a sample of the population, and reason about the representativeness of the sample. Then, students begin to develop intuition about appropriate sample size by conducting an experiment. They compare different sample sizes, and decide whether increasing the sample size improves the results. In Lesson 16 and Lesson 17, students compare two data sets using any tools they wish. Students will be reminded of Mean Average Deviation (MAD), which will be a useful tool in this situation. Students complete another Self Check, review the results of their Self Check, and solve additional problems. The unit ends with three days for students to work on Gallery problems, possibly using one of the days to complete their project or get help on their project if needed, two days for students to present their unit projects to the class, and one day for the End of Unit Assessment.

Students are introduced to our planet's structure and its dynamic system of natural forces through an examination of the natural hazards of earthquakes, volcanoes, landslides, tsunamis, floods and tornados, as well as avalanches, fires, hurricanes and thunderstorms. They see how these natural events become disasters when they impact people, and how engineers help to make people safe from them. Students begin by learning about the structure of the Earth; they create clay models showing the Earth's layers, see a continental drift demo, calculate drift over time, and make fault models. They learn how earthquakes happen; they investigate the integrity of structural designs using model seismographs. Using toothpicks and mini-marshmallows, they create and test structures in a simulated earthquake on a tray of Jell-O. Students learn about the causes, composition and types of volcanoes, and watch and measure a class mock eruption demo, observing the phases that change a mountain's shape. Students learn that the different types of landslides are all are the result of gravity, friction and the materials involved. Using a small-scale model of a debris chute, they explore how landslides start in response to variables in material, slope and water content. Students learn about tsunamis, discovering what causes them and makes them so dangerous. Using a table-top-sized tsunami generator, they test how model structures of different material types fare in devastating waves. Students learn about the causes of floods, their benefits and potential for disaster. Using riverbed models made of clay in baking pans, students simulate the impact of different river volumes, floodplain terrain and levee designs in experimental trials. They learn about the basic characteristics, damage and occurrence of tornadoes, examining them closely by creating water vortices in soda bottles. They complete mock engineering analyses of tornado damage, analyze and graph US tornado damage data, and draw and present structure designs intended to withstand high winds.

3) You will then explore trends on your data and create graphs/visual representations of these trends using MS-Excel;

4) Finally, you will compile all your conclusions, evaluate the accuracy of your prediction (hypothesis), and create a report of your findings.

Students learn about floods, discovering that different types of floods occur from different water sources, but primarily from heavy rainfall. While floods occur naturally and have benefits such as creating fertile farmland, students learn that with the increase in human population in flood-prone areas, floods are become increasingly problematic. Both natural and manmade factors contribute to floods. Students learn what makes floods dangerous and what engineers design to predict, control and survive floods.

Students learn about the water cycle and its key components. First, they learn about the concept of a watershed and why it is important in the context of engineering hydrology. Then they learn how we can use the theory of conservation of mass to estimate the amount of water that enters a watershed (precipitation, groundwater flowing in) and exits a watershed (evaporation, runoff, groundwater out). Finally, students learn about runoff and how we visualize runoff in the form of hydrographs.
