Thanksgiving Lesson Plan Acrostic Poem

Thanksgiving Lesson Plan Acrostic Poem Are you in need of a quick and easy Thanksgiving lesson plan to share with your students in the week before Thanksgiving? Consider practicing acrostic poetry with your students. Acrostic poetry is great for building vocabulary and exercising creativity.   An acrostic poem uses the letters in a word to begin each line of the poem. All of the lines of the poem relate to or somehow describe the main topic word. Here are a few quick tips to consider. Model the format of acrostic poems with your students. Work together to write a collective acrostic poem on the whiteboard. You can use the sample below.Give your students a Thanksgiving-related word so that they can write their own acrostic poem. Consider: gratitude, thank you, Thanksgiving, thankful, blessings, or grateful. Discuss the meaning of these words and the true meaning of the Thanksgiving holiday.Give your students time to write their acrostic poems. Circulate and offer guidance as needed. Offer help but do not give students any phrases or sentences; let them do that on their own.If you have time, allow the students to illustrate their poems. This project makes a great bulletin board display for November, especially if you do it early in the month! Your students can even give their gratitude poems to family members as a creative way of saying thank you for all they do. Sample Thanksgiving Acrostic Poem Here are a few samples of Thanksgiving acrostic poems. Sample number three is written for someone. Sample No. 1 G - Giving me tasty food to eatR - Reading to me before I go to bedA - Always working hard for our familyT - Treating me sweetlyI - I appreciate you!T - Tucking me into bed at nightU - Understanding me when Im upsetD - Doing the right thingsE - Excellent parents! Sample No. 2 T - urkey time (I love the white meat!)H - oping the weather will stay coolA - untie’s pumpkin pie is my favoriteN -   ine plates around the family dinner tableK - eeping family traditions aliveS - tuffing my tummy with my nanas super stuffingG - iving thanks for my family and friendsI - nviting our elderly neighbors over so they won’t be lonelyV   - egetables that I love are corn and beansI - think I am about to burst from all of the foodN - aps for the babies, grandparents, and all of us!G - ames and laughter throughout the day! Sample No. 3 T - Thank you for alwaysU - Understanding. Thank you for alwaysR - Remembering to beK - Kind, helpful, generous, nice, and respectful ofE - Each other. That is why I am so happy and thankful everyY - Year for everything that you do for me.

What to Know About Zeta Potential

What to Know About Zeta Potential The zeta potential (ÃŽ ¶-potential) is the potential difference across phase boundaries between solids and liquids. Its a measure of the electrical charge of particles are that are suspended in liquid. Since zeta potential is not equal to the electric surface potential in a double layer or to the Stern potential, it is often the only value that can be used to describe double-layer properties of a colloidal dispersion. Zeta potential, also known as electrokinetic potential, is measured in millivolts (mV). In colloids, zeta potential is the electric potential difference across the ionic layer around a charged colloid ion. Put another way; its the potential in the interface double layer at the slipping plane. Typically, the higher the zeta-potential, the more stable the colloid. Zeta potential that is less negative than -15 mV typically represents the beginnings of agglomeration of particles. When the zeta-potential equals zero, the colloid will precipitate into a solid. Measuring Zeta Potential Zeta potential cannot be directly measured. It is calculated from theoretical models or estimated experimentally, often based on electrophoretic mobility. Basically, to determine zeta potential, one tracks that rate at which a charged particle moves in response to an electric field. Particles that possess a zeta potential will migrate toward the opposite-charged electrode. The rate of migration is proportional to zeta potential. Velocity typically is measured using a Laser Doppler Anemometer. The calculation is based on a theory described in 1903 by Marian Smoluchowski. Smoluchowskis theory is valid for any concentration or shape of dispersed particles. However, it assumes a sufficiently thin double layer, and it ignores any contribution of surface conductivity. Newer theories are used to perform electroacoustic and electrokinetic analyses under these conditions. There is a device called a zeta meter its expensive, but a trained operator can interpret the estimated values that it produces. Zeta meters typically rely on one of two electroacoustic effects: electric sonic amplitude and colloid vibration current. The advantage of using an electroacoustic method to characterize zeta potential is that the sample does not need to be diluted. Applications of Zeta Potential Since the physical properties of suspensions and colloids largely depend on the properties of the particle-liquid interface, knowing the zeta potential has practical applications. Zeta Potential Measurements are used to Prepare colloidal dispersions for cosmetics, inks, dyes, foams, and other chemicalsDestroy undesirable colloidal dispersions during water and sewage treatment, preparation of beer and wine, and dispersing aerosol productsReduce cost of additives by calculating the minimum amount needed to achieve the desired effect, such as the amount of flocculant added to water during water treatmentIncorporate colloidal dispersion during manufacturing, as in cements, pottery, coatings, etc.Utilize desirable properties of colloids, which include capillary action and detergency. Properties may be applied for mineral flotation, impurity absorption, separating petroleum from reservoir rock, wetting phenomena, and electrophoretic deposition of paints or coatingsMicroelectrophoresis to characterize blood, bacteria, and other biological surfacesCharacterize the properties of clay-water systemsMany other uses in mineral processing, ceramics manufacturing, electronics manufacturing, pharmaceutical producti on, etc. References American Filtration and Separations Society, What Is Zeta Potential?
