Embryology+101

Show chicken dance video- hysterical! [] Techno chicken (just for fun) [] Brainstorm and create web “What do you know about chickens and eggs?” Example: (check out Bubbl.us.com for online mapping tool that is easy to use and project using 3M) Powerpoint from PSU 4-H club- Embryo development •Count the number of eggs set. • Guess how many eggs will hatch. • Count the number of eggs that hatch and create fractions to represent hatch. Convert fractions to percentages to determine percent of eggs hatched. • Break open an UNFERTILIZED egg (from the store) and point out major parts-use 4-H book as reference [] lesson plan for exploring parts of an egg • Draw an egg and label egg parts • Describe which parts of the egg we eat. • Explain why the eggs from the grocery store are not fertile. • Draw an embryo and label parts.

 * Embryology 101 by Kellie [[image:chick_peeking.gif]]**
 * Objectives:**
 * To increase knowledge and develop personal confidence and leadership ability through embryology project activities.
 * To develop youth interest in the science of embryology.
 * To provide learning experiences in incubation, hatching and brooding.
 * To provide opportunities to demonstrate skills mastered in embryology.
 * Introduction:** (optional)
 * Embryology Math Connection**
 * Essential Questions:**
 * What is in an egg? What is the difference between fertilized and non-fertilized?**

• Tell what each part does. • Tell how a chick gets its food while growing in the egg. Lots to do with an egg []

Know how to operate an incubator during incubation • Describe the functions of the hen. • Describe the function of the incubator. • Compare the hen and the incubator by explaining what they each provide for the egg and how. • Prepare an incubator for eggs. • Read a thermometer- (Can review temperature/thermometer lessons) • Set the thermostat to the correct temperature-( **100.5 degrees F**, up or down 1 degree is fine, under 98 or above 102 is NO good) • Turn the eggs three times a day, let them rest overnight on a different side each night. • Journal entry: Write down the number of eggs you expect will hatch and explain the hatching process [|**http://chickscope.beckman.uiuc.edu/explore/embryology/**] Each Day is a clickable link to show photo and info about that stage of development [|**http://urbanext.illinois.edu/eggs/res27-timing.html**] • Candle eggs each day during incubation beginning at Day 3. (candle means shine light through to look for dark shadow) the dark shadow is chick growth, the dark spot should be fairly large and continue to get larger each day if chick is developing. Eggs with no dark shadow usually don’t have chicks developing inside) • Write a list of things that would be good for a chick to eat. • What are some things that would not be good to eat and why? • Compare this list to things that are good for you to eat. • Describe how a chick lives and eats while still an embryo in the egg. • Draw the food pyramid showing the basic foods that children need. Try to eat one of each basic food every day and see how your body feels. Follow steps of scientific method to conduct an experiment HM reading books Scale to weigh one book (in my cabinet, its metric) Desk and newspapers to hold eggs and mess Have students make their hypothesis and write in science journals Then one at a time, have students place books on top of 4 eggs (evenly) keep counting until they crack Then add up # of books, multiply by weight of 1 book, then divide by 4= weight that one egg can hold • Keep a record of how many eggs were set, how many eggs were broken-out for study and how many eggs hatched. • Use My 4-H Record. Keep a record of incubator temperature and humidity each time the eggs are turned. • Keep a record of the weather, the high and low temperatures each day that the eggs are in the incubator. Record any unusual weather (incubator) conditions, problems, etc. • Write word problems about hatching and incubation. •Watch a chick hatch [] • Gently and carefully hold a chick in your hands.

 * What is an incubator and how does it work?**
 * What happens inside an egg?**
 * Understand changes that occur during incubation** (refer to poster chart of embryo development or website above**)**
 * PSU Powerpoint (embryonic development stages with lots of photos)-** [|**http://extension.psu.edu/4-h/projects/poultry/embryology/teacher-resources/powerpoints/embryonic-development/view**]
 * How does nutrition affect living things?**
 * Science Experiment: How strong is an egg?**
 * “How much weight can an egg hold?”**
 * Materials:** 4 NON-FERTILIZED eggs set in 4 soda bottle caps (in my sink drawer)
 * STEPS:**
 * Keeping records and a science journal**
 * Day 1- Embryology 101 “What does embryology mean and what will you be learning?”**
 * Day 2- Proper incubation methods “ Explain about proper incubation temperature, time,…”**
 * Day 3 Embryo growth “Describe what happens inside an each during incubation”**
 * Day 4 What do you expect to see on Monday? Predict hatch**
 * How does a chick hatches?**
 * How to make a brooder**
