Second graders in Ms. Czeczotka and Ms. Moran's class at Babylon Elementary School combined a literacy and STEM lesson to create their own Thanksgiving Day parade balloons on Nov. 18. A favorite picture book is Rosie Revere, Engineer. Favorite Series & Authors. Mr. Greg (who was wearing a green shirt this day…). With encouragement from her great aunt who applauds her efforts, Rosie learns to persevere and use failure as a learning tool during the design process. But how does the balloon inflate? Interest Level: Grades K-3. Turkey, stuffing and pumpkin pie are all wonderful traditions. With "Balloons Over Broadway" as our starting point for our unit, we have been able to integrate reading, research, science, technology, engineering, and math during the busy week before Thanksgiving. The big balloons used in the parade use anywhere from 300, 000 to 700, 000 cubic feet of Helium. Wit & Wisdom Collections. All him and his ideas! Fifty million television viewers tune in to enjoy everything from marching bands to Broadway show tunes, floats and the celebrated giant character balloons.
Follow these step-by-step instructions to engage your students in this real-world STEM challenge! This book tells the story of the Macy's Thanksgiving Day Parade. The permanent markers will smear if you touch it before it dries, but once it's dry, it will stay on the balloon. Rebecca Turner Elementary School hosts first Balloons Over Broadway parade. Before having students build get their creativity muscles going by having them brainstorm as many different balloon designs as possible in 3 minutes. The students have to read and follow the directions to draw the parade route as well as answer questions about the map. Next we head to our computers to conduct research on the parade and balloons.
Science of Reading Foundational Support. The vinegar and the baking soda, when mixed together, create an acid-base reaction. Elections, Parades, Football, Pumpkins, Thanksgiving, and Turkeys: we have all those topics covered for your classroom! I just blow up the balloons. This challenge can work with any robot. These STEM activities and Google Slides are connected to the book by Melissa Sweet. The M in STEM - Math. The economic sanctions and trade restrictions that apply to your use of the Services are subject to change, so members should check sanctions resources regularly.
As a global company based in the US with operations in other countries, Etsy must comply with economic sanctions and trade restrictions, including, but not limited to, those implemented by the Office of Foreign Assets Control ("OFAC") of the US Department of the Treasury. During the reading, we'll note how they're used in the context of the story and students will be expected to define them or use the terms appropriately in a sentence that shows their understanding of the word. Plus, I found it quite fascinating as an adult! Jennifer Serravallo Reading Collections. Those amazing balloons provide great examples for STEM lessons.
Start by pouring the flour and water in a large bowl and stir it well. Add as much water as needed to mix to make the mixture runny like white glue (make sure it is not thick like a paste). Eventually the puppets were replaced by large balloons. In addition to the regular literature curriculum that we have in our classrooms, we have been delighted by the recent surge of books with strong STEM and engineering connections. After we create the pictures, I print them at Walgreens.
A few of the student character creations included Shrek, Turkey, Baby Shark, Sonic, Dogman, Mickey and Minnie Mouse. Animals, superheroes, food, etc. Kelli swapped out the balloons for a green cup and a green popsicle stick. Student Mia Klein designed a gnome for her STEM balloon using pipe cleaners, a red balloon, paper, a coffee filter, and pom poms. STEAM Challenge: Can you create your own balloon parade? This is such a meaningful project for this time of year, where the students can be inspired to create and dream! They then utilize the mold to create a plastic balloon. Targeted Readers At/Above/Below Level. Please see my disclosure for more details. He then took his ideas and made a concrete plan. Tape a wooden paint stick or ruler to the back of your balloon. We hang a copy in our classroom and we send a copy home to the families! Here was his initial idea: So he went to work but found that when he just taped his straw legs on, they went in at an angle since the side of the balloon was at an angle: So he went "back to the drawing board" and brainstormed on a solution.
They've given me the original line's equation, and it's in " y=" form, so it's easy to find the slope. I'll pick x = 1, and plug this into the first line's equation to find the corresponding y -value: So my point (on the first line they gave me) is (1, 6). Then the full solution to this exercise is: parallel: perpendicular: Warning: If a question asks you whether two given lines are "parallel, perpendicular, or neither", you must answer that question by finding their slopes, not by drawing a picture! I'll solve each for " y=" to be sure:.. Since slope is a measure of the angle of a line from the horizontal, and since parallel lines must have the same angle, then parallel lines have the same slope — and lines with the same slope are parallel. That intersection point will be the second point that I'll need for the Distance Formula. Parallel and perpendicular lines 4-4. 99, the lines can not possibly be parallel. This is just my personal preference. So I can keep things straight and tell the difference between the two slopes, I'll use subscripts. If you visualize a line with positive slope (so it's an increasing line), then the perpendicular line must have negative slope (because it will have to be a decreasing line). It will be the perpendicular distance between the two lines, but how do I find that?
If I were to convert the "3" to fractional form by putting it over "1", then flip it and change its sign, I would get ". If your preference differs, then use whatever method you like best. ) Pictures can only give you a rough idea of what is going on. The lines have the same slope, so they are indeed parallel. Parallel lines and their slopes are easy.
Then my perpendicular slope will be. Hey, now I have a point and a slope! Yes, they can be long and messy. 7442, if you plow through the computations. Now I need to find two new slopes, and use them with the point they've given me; namely, with the point (4, −1). Equations of parallel and perpendicular lines.
There is one other consideration for straight-line equations: finding parallel and perpendicular lines.
Put this together with the sign change, and you get that the slope of a perpendicular line is the "negative reciprocal" of the slope of the original line — and two lines with slopes that are negative reciprocals of each other are perpendicular to each other. I'll find the values of the slopes. This is the non-obvious thing about the slopes of perpendicular lines. ) Here is a common format for exercises on this topic: They've given me a reference line, namely, 2x − 3y = 9; this is the line to whose slope I'll be making reference later in my work. Since the original lines are parallel, then this perpendicular line is perpendicular to the second of the original lines, too. 4-4 parallel and perpendicular lines answers. This would give you your second point. These slope values are not the same, so the lines are not parallel.
Clicking on "Tap to view steps" on the widget's answer screen will take you to the Mathway site for a paid upgrade. Then you'd need to plug this point, along with the first one, (1, 6), into the Distance Formula to find the distance between the lines. Here's how that works: To answer this question, I'll find the two slopes. You can use the Mathway widget below to practice finding a perpendicular line through a given point. This line has some slope value (though not a value of "2", of course, because this line equation isn't solved for " y="). So perpendicular lines have slopes which have opposite signs. With this point and my perpendicular slope, I can find the equation of the perpendicular line that'll give me the distance between the two original lines: Okay; now I have the equation of the perpendicular. For instance, you would simply not be able to tell, just "by looking" at the picture, that drawn lines with slopes of, say, m 1 = 1. It turns out to be, if you do the math. ] Since a parallel line has an identical slope, then the parallel line through (4, −1) will have slope. In other words, they're asking me for the perpendicular slope, but they've disguised their purpose a bit.
Try the entered exercise, or type in your own exercise. Here are two examples of more complicated types of exercises: Since the slope is the value that's multiplied on " x " when the equation is solved for " y=", then the value of " a " is going to be the slope value for the perpendicular line. Then I flip and change the sign. But how to I find that distance? The only way to be sure of your answer is to do the algebra. For the perpendicular slope, I'll flip the reference slope and change the sign.
To answer the question, you'll have to calculate the slopes and compare them. Note that the distance between the lines is not the same as the vertical or horizontal distance between the lines, so you can not use the x - or y -intercepts as a proxy for distance. I know the reference slope is. I'll solve for " y=": Then the reference slope is m = 9.
The other "opposite" thing with perpendicular slopes is that their values are reciprocals; that is, you take the one slope value, and flip it upside down. But even just trying them, rather than immediately throwing your hands up in defeat, will strengthen your skills — as well as winning you some major "brownie points" with your instructor. I'll leave the rest of the exercise for you, if you're interested. Remember that any integer can be turned into a fraction by putting it over 1. In other words, these slopes are negative reciprocals, so: the lines are perpendicular.
In other words, to answer this sort of exercise, always find the numerical slopes; don't try to get away with just drawing some pretty pictures. Content Continues Below. I'll find the slopes. I start by converting the "9" to fractional form by putting it over "1". Otherwise, they must meet at some point, at which point the distance between the lines would obviously be zero. ) The result is: The only way these two lines could have a distance between them is if they're parallel. I know I can find the distance between two points; I plug the two points into the Distance Formula.
