7th Grade Science- Mrs. Gomula

Extra help is available before school and during recess. Students should make arrangements for specific days due to meetings and lunch coverage. 

MAY: Almost over! Just a few weeks more until finals and the end to a great year. Students will begin work on their Ecology unit and are researching specific Biomes. Their project will include a shoebox diorama along with their research information and a poem. Can't wait to see how creative they are.Image result for free clipart ecology biomes

APRIL: OLM students are awaiting the Risen Lord and will enjoy a week's vacation this month. Students continue to explore topics such as Human Body Systems and are looking forward to their chicken wing dissection activity.

MARCH: Students completed their Unit exploring Life Over Time. The students created a geologic time line out of toilet paper which will be put up around the classroom. Students will move on to study organisms on earth and their characteristics that help them survive.



FEBRUARY: Students began work in their Diversity of Living Things workbook this month and have been investigating Darwin's theories. Students will investigate Darwin's studies on the evolution of bird beaks from his studies on Galapagos Island finches before heading off to a week of rest and relaxation. Enjoy the Winter Break!


Thanks to all of our students at OLMS for their hard work on the Mercy Contraption. What an amazing accomplishment. It was great to see our students applying science concepts, helping with the design, and working as a team. Congratulations on a job well done.


CATHOLIC SCHOOLS WEEK BEGINS JANUARY 28 - invite your family and friends to visit Our Lady of Mercy School in Hicksville to see the wonderful programs available that "challenge each student intellectually, motivate each student in the pursuit of academic excellence, and prepare each student for further educational opportunities."    (OLM School Philosophy)


JANUARY:Students are investigating Heredity and cell division in Mitosis and Meiosis. The students are working on a Stop/Motion project on the I-Pad to create the stages of cell division in a movie format. Links to videos for cell division are posted under "Useful Links" in the upper left corner of this page. Work will begin on building a DNA strand during our visits to the Discovery Room this month. Students are discussing projects for possible submission in the Nassau County Science Fair in June and are looking forward to more STEAM challenges.

HAPPY NEW YEAR AND WELCOME BACK!
  Thank you to everyone for your wishes for a healthy and happy New Year and wonderful gifts.

DECEMBER:  Students will be completing their Unit on Cells by exploring Photosynthesis and Cellular Respiration. The students completed a fun lab on Homeostasis and will be working on building a model of a DNA strand for the classroom. Up next will be learning why cells divide and the stages of Mitosis and Meiosis.

  Wishing everyone a very happy and healthy Christmas and New Year.

NOVEMBER
: An exciting trip to Philadelphia, PA has been planned for November 3. 7th grade students will be completing their Unit on Cells with investigations on Homeostasis, Photosynthesis and Cellular Respiration. 
     Students will complete their Pumpkin Lab and utilize the data they collected during October and will incorporate Math by graphing the data.
 
October: Technology Day is Thursday, October 12 at Adventureland. The first Quiz on Cells will be on Friday, October 6, 2017. Use workbook, notes and labs to study.
   Students were in the Discovery Room to study building designs. They created a prototype and are in discussion with their group members regarding any re-engineering that will be needed to improve the design.

SEPTEMBEROur 7th grade students began the school year by diving into Cell structure and functions. Today the students learned to prepare a microscope slide and were able to view the plant cells of an onion skin.

Welcome to another exciting year of learning. We’ll be collaborating with each other to analyze new concepts and exploring these concepts further through exciting labs. Challenges await you in our new Discovery Room that has been stocked with STEAM materials that will peak your curiosity and allow you to improve your problem solving skills. Look forward to a year of Science FUN!

               SOLAR ECLIPSE 2017


     A solar eclipse occurs when the moon completely covers the sun in the sky. The total solar eclipse will occur on August 21, 2017 and the path it will take stretches from Oregon to South Carolina. The event will last about 2 minutes and 40 seconds.
CAUTION: REMEMBER NOT TO LOOK DIRECTLY AT THE ECLIPSE WITHOUT SOLAR VIEWING GLASSES. SUNGLASSES ARE NOT TO BE USED IN PLACE OF THESE SOLAR VIEWING GLASSES.
     Check out the website Space.com for information on when, where and how to see the solar eclipse safely.
     NASA has a website dedicated to the eclipse. Check it out at eclipse.gsfc.nasa.gov.

                          

            SUMMER SCIENCE

School may be out but you can still study Science by doing experiments and STEAM challenges. Since we just celebrated the 4th of July, you can duplicate the colors of the fireworks in this experiment.

                                 FIREWORKS IN A JAR

MATERIALS:
1 clear jar (like a mayonnaise or mason jar)
warm water
plastic disposable plate or a pie pan (should have a rim so oil won't spill out)
different colors of food coloring
4-tablespoons of cooking oil (Canola, Mazola, etc.)
fork

PROCEDURE:
1. Fill the jar 3/4 of the way with warm water.
2. Put 4-tablespoons of oil in the pie pan or plastic plate.
3. Carefully put drops of different colors of food coloring in the oil in the pie plate or plastic plate. (It should look like dots of color. You should have about 10-12 drops.)
4. Gently use the fork to break up the dots of food coloring. (This should now look like small particles in the oil.)
5. GENTLY pour the oil and food coloring mixture into the jar. GENTLY! (It helps if you have someone help you and tilts the jar of water so you can gently introduce the oil mixture.)

WHAT HAPPENS? You should see the food coloring slowly sink out of the oil and into the water. When this happens, it will expand and begin to mix with the other colors.

WHY THIS HAPPENS - Food coloring dissolves in water but not oil. Since the oil is less dense than water, it will float on top of the water. The food coloring drops will begin to sink because they are heavier than the oil. Once they sink into the water they begin dissolving in the water. This will look like a tiny explosion of color. ENJOY!

Come back for another experiment or STEAM challenge over the summer.
