Engineering Family Fun Day Promotes Interest In Math and Science
On Saturday, November 3rd, Seminole SECME will be participating in the fifth annual “Engineering Family Fun Day” in Dreher Park – Pavilion 3 (across from the Dreher Park Zoo) in West Palm Beach. The Society of Women Southeast Florida Section and the Palm Beach Alumni Extension of the National Society of Black Engineers are co-hosts.
The event will involve eight booths. Each sponsored booth presents a hands on engineering related activity by which the students, parents, teachers, councelors and engineers can interact with each other. For example, the Bottle Rocket involves aerospace engineering and Making Polymers involves science and chemistry. SECME will be presenting "Inspector Detector" from the upcoming Design Squad "Beyond the Moon" guide.
We challenge you to…
…build a device that can that you can pass above a surface and detect magnetic fields.
1. Brainstorm and Design
• How can you make sure that the metal shards stay in your detector and not fall off?
· How can you make it easy to see when the metal shards move?
· How will you hold the detector as you move it above the surface?
2. Build
Invent your own designs.
3. Test
· Try out your detector. At our booth, use the small magnet to test how well your detector works.
· Find the hidden magnets. Take your detector to the newspaper grid. (it represents a map of Mars' surface.) Find the magnets by slowly passing your detector over the grid, one section at a time.
· Map the magnets. Using the grid lines to identify the locations, mark each magnet with a dot on your map (NOT on the newspaper).
· Map the magnets. Using the grid lines to identify the locations, mark each magnet with a dot on your map (NOT on the newspaper).
4. Evaluate and Redesign
· If it’s hard to see the shards move… Design a window or remove parts that block your view.
· If your detector doesn’t respond… Check that you have enough metal shards and that nothing is interfering with how they move. Also check that you’re not holding it too far above the surface.
5. Go Further
- Upgrade your detector. Make it sensitive enough to work six inches above the surface.
- Magnet Treasure Hunt. You’re surrounded by magnets! Use your detector and see how many invisible fields you can find. Check things like speakers and electric motors.

20121018 Popfly Launcher
Pop-Fly Launcher.
http://teachers.egfi-k12.org/pop-fly/
Summary:
In this lesson, student teams in grades 3 – 12 will explore the engineering design process by building a device that can launch a ping-pong ball high enough for them to catch it. We challenge students to make something that launchs a ball high enough for them to catch it, using the materials and their feet.
Learning Objectives: After this activity, students will understand how levers convert a small motion into a large motion, and how engineers consider resource constraints and the laws of physics when developing and improving their designs.
Common Core State Standards
CCSS.MATH.CONTENT.HSG.SRT.D.11 Understand and apply the Law of Sines and the Law of Cosines to find unknown measurements in right and non-right triangles (e.g., surveying problems, resultant forces).
CCSS.ELA-LITERACY.RST.9-10.3 Follow precisely a complex multistep procedure when carrying out experiments, taking measurements, or performing technical tasks, attending to special cases or exceptions defined in the text.
CCSS.ELA-LITERACY.RST.9-10.6 Analyze the author's purpose in providing an explanation, describing a procedure, or discussing an experiment in a text, defining the question the author seeks to address.

(Click on the first picture to flip through a photostream of 2012 Raingutter Regatta)
Gotta Regatta Raingutter Race: Seminole Ridge HS physics students were challenged to make the fastest ferry for a Ping-Pong passenger. Using limited supplies teams had to design and build a boat that travels across a container of water.
Complete challenge is available here:

Mousetrap Vehicle Calculations for Design Excellence
Mousetrap Vehicle Calculations for Design Excellence
There are two main stages of travel for mousetrap vehicles (MTV). The first is the powered stage and the second is the coasting stage. There is a possible third stage that should be avoided by careful routing of the string – the breaking stage – since this will reduce distance but with no positive offsetting effect.
Since the powered stage accounts for the majority of the distance and the time used, it is wise to optimize this phase. To begin the design, we’ll ignore length and weigh considerations (but they should be evaluated as part of the final MTV design). Once the initial design is complete, trade-offs and improvements can be made.
To calculate distance under power for an existing MTV design, you determine how many times the wheel will rotate and multiply that by its circumference to get total distance. If the vehicle does not perform as anticipated then you can look for losses due to slippage and other factors, or perhaps a math error. Include units in all calculations to avoid use of conflicting units (dimensional analysis).

Can You KenKen?
KenKen is a logic puzzle that involves arithmetic. Similar to SuDoku, KenKen will exercise your mind as you fill in the blanks. KenKen is a game that helps students improve their calculation skills, logical thinking and persistence. The goal is to fill a grid with numbers so that no number appears more than once in any row or column. In addition, the numbers must combine to form a target number using a specific operation of addition, subtraction, multiplication and division.
KenKen logic puzzles were first invented in Japan by Tetsuya Miyamoto, promoted as “Kashikoku Naru Puzzle” or the "Makes You Smarter" puzzle. With the main goal to improve students’ cognitive abilities in mind, he developed a brain stimulating exercise that would be understandable, fun and challenging for students of all levels.
The puzzle is used to teach Common Core mathematical processes and is prominently featured on the National Council of Teachers of Mathematics' Illuminations website. (NCTM is the world's largest organization devoted to math education). KenKen puzzles can also be played for free at http://www.KenKen.com.
The KenKen Classroom Program (KKCR) is a weekly set of puzzles that range in size from 3x3 to 5x5 grids, with two 6x6 teamwork puzzles, sent as PDF to teachers once a week, usually on Sundays. The puzzle sets are carefully selected to ensure that they are fit for all class levels and skill levels, from gifted children as well as for students with learning disabilities!
Rules for KENKEN
1. Every square in the grid will contain one number. In a 4 x 4 puzzle, use the numbers 1–4. In a 5 x 5 puzzle, use the numbers 1–5.
2. Each row and each column must contain the numbers 1 through 3 (easy) or 1 through 5 (challenging). Do not repeat numbers in any row or column.
3. A cage is a heavily outlined set of squares. Every cage has a target number in the upper left corner. The numbers in the squares inside a cage must combine to produce the target number using the given operation in any order to produce the target numbers in the top-left corners.
4. Freebies: Cages with just one square should be filled in with the number in the top-left corner. This is a good place to start solving the puzzle.
KENKEN and the Common Core CCSS.Math.Content.HSA-CED.A.1 Create equations and inequalities in one variable and use them to solve problems.
CCSS.Math.Content.HSA-CED.A.4 Rearrange formulas to highlight a quantity of interest, using the same reasoning as in solving equations.
KenKen emphasizes logical thinking and problem solving in the context of basic operations. The math puzzle improves numeracy skills and logical thinking, and develops concentration, perseverance and stamina. The puzzle’s universality, with an array of difficulty levels and no language, gender or age requirements, allows all students the chance to participate.
