The math of Gardening!!! <ul><li>Liz Salois </li></ul>

Rototilling your Garden! <ul><li>Gardens come in all sorts of shapes! Squares, rectangles, triangles, circles and more! </li></ul><ul><li>I’m going to make mine a square! </li></ul><ul><li>I have to measure out four equal sides and measure the angle to make sure they are 90 degrees. These are called right angles. </li></ul><ul><li>We can also make rectangle and square beds in the garden for the seeds! </li></ul>* Geometry
3.
Putting up your Fencing <ul><li>I want my square to be 10 by 10 feet and to have a three foot wide gate on one side. This means that I need to measure out 37 feet of fencing. ((4 sides x 10 feet)-3)=37 </li></ul><ul><li>If I didn’t have enough fencing, I could use this equation to figure out what dimensions my garden should be. (4 sides x a ft)-3ft =Amount of available fencing or (Amount of available fencing+3ft)/4sides=a ft (where a =length in ft of sides) So if I had 21 ft of fencing, I could make a 6x6 garden. (21ft+3ft)/4sides=6 ft </li></ul><ul><li>We can also figure out the area of the garden by squaring the length of one side! So our 10x10 garden is 100 square feet!!! (10x10=100) </li></ul>* Algebra
4.
Buying the Seeds! <ul><li>Here is my shopping list for seeds: </li></ul><ul><li>A packet of zucchini seeds....$3.95 A packet of cucumber seeds....$3.95 2 packets of summer squash....$4.95 A packet of pumpkins....$3.95 A packet of carrots....$4.95 A packet of cauliflower....3.95 A packet of sunflowers...$4.95 2 packets of sweet peas....$4.95 A packet of mixed flowers....$3.95 A packet of snapdragons....$3.95 For a total of $53.40 </li></ul><ul><li>We can also use multiplication to figure out the total cost. (6($4.95))+(6($3.95))=$53.40! or 6($4.95+$3.95)=$53.40! </li></ul>*numbers and operations
5.
Planting Cauliflower! <ul><li>Each type of plant has to be buried at a specific depth, and spaced evenly along the row. </li></ul><ul><li>To make the rows we need to use string to make a straight line! </li></ul><ul><li>Then we have to dig holes that are 13mm deep and 15cm apart from each other. This is the same as about 1/2 an inch deep and 6 inches apart from each other! </li></ul>*Measurement
6.
Patterns with Bricks! <ul><li>I want to lay down a brick walkway so that the paths don’t get muddy! </li></ul><ul><li>There are so many patterns to chose from, but I’m going to try making the basket weave. I have to use sets of two parallel bricks which are placed horizontally next to a set placed vertically . You just repeat this pattern the whole time! </li></ul>
7.
Fractals! <ul><li>There are fractals everywhere in nature! </li></ul><ul><li>The type of cauliflower I am growing is a great example! When you zoom in on the plant, you see that it is made up of smaller patterns of the original shape of the plant. </li></ul><ul><li>You are growing complex geometric shapes and they taste great!! </li></ul>*Geometry
8.
Mixed Flowers! <ul><li>We have one packet of mixed flowers! </li></ul><ul><li>There are 12 seeds and 6 of them are poppies, 4 are violets and 2 are daisies. </li></ul><ul><li>If I planted only one seed, the probability of it being a poppy is 6 in 12 which is the same as 1/2, 50% or .5! </li></ul><ul><li>The probability of it being a violet is 4 in 12 which is the same as 1/3, 33% or .333! </li></ul><ul><li>And the probability of it being a daisy is 2 in 12 which is the same as 1/6, 16.6% or .1666! </li></ul><ul><li>I’m guessing it will be a poppy! </li></ul>*Data Analysis and Probability
9.
Plant Growth! <ul><li>Measuring your plant’s growth!!! </li></ul><ul><li>I’m going to make a chart where I can record the weekly growth of my plants!!! </li></ul><ul><li>I can measure in centimeters, inches, feet, popsicle sticks, hands or any other fun unit! </li></ul><ul><li>I might want to use smaller units like centimeters for tiny plants and larger units like hands for taller plants such as a sunflower! </li></ul>*Measurement
10.
Watering the Garden <ul><li>I water the garden twice a day! Once in the morning and once in the evening! </li></ul><ul><li>I water it for about 10 minutes each time and the hose pumps out about 9 gallons of water per minute. This means I pump out 180 gallons of water per day! (2(10 mins x 9 gallons))=180 gallons </li></ul><ul><li>That is 1,260 gallons a week! (180 gallons x 7 days)=1,260 gallons </li></ul><ul><li>And is about 5,040 gallons a month! (1,260 gallons x 4 weeks)= 5,040 gallons </li></ul><ul><li>That’s about 19, 708 liters a month, or 9,539 2liter bottles of soda! </li></ul>*numbers and operations
11.
sunflower seeds! <ul><li>I want to know how many seeds are on one sunflower! </li></ul><ul><li>There are too many to count so I am going to estimate how many there are! </li></ul><ul><li>I know that there are about 10 seeds in an area about the size of a quarter so I am going to estimate that I could fit about 30 quarters on my sunflower so I think I must have about 300 sunflower seeds on each flower. </li></ul>
12.
3D Shapes in the garden! <ul><li>There are all sorts of 3D shapes to be found! </li></ul><ul><li>Tomatoes are a great example of spheres! </li></ul><ul><li>Carrots are upside down cones! </li></ul><ul><li>Cucumbers are ellipses! </li></ul><ul><li>Another fun shape is the star found inside an apple but it is a 2D shape. </li></ul>* Geometry
13.
Salad! <ul><li>I am going to make a salad with all the vegetables I have grown! </li></ul><ul><li>I need half a cup of sliced carrots. (about 3 carrots) </li></ul><ul><li>1 cup of sliced cucumbers. (about 3/4 of a cucumber) </li></ul><ul><li>1 cup sliced tomatoes. (about 1 tomato) </li></ul><ul><li>1/2 a cup of sunflower seeds.(about 3/4 of a flower) </li></ul><ul><li>And 4 cups of lettuce. (about 2 small heads of lettuce) </li></ul><ul><li>After everything is washed and cut, toss it together and add some homemade balsamic vinaigrette! Yum!!!!! </li></ul>*Measurement
Clipping is a handy way to collect and organize the most important slides from a presentation. You can keep your great finds in clipboards organized around topics.
