Heat and Ozone Guidelines
During the hot days of summer, early fall, and late spring, there are frequently ozone alerts. There will be no outside activity if the temperature humidity index is 95 degrees or greater, or when under Heat Alert, Red Ozone Alert, or Orange Ozone Alert.  It is acceptable for students to be outside on these days for 10 minutes or less if they have to go outside to get to the gym, check on a garden area, etc.  Parents should provide the school with written notice if they would like their child to not go outside on days other than listed above.
Cold Temperatures
Students will not be allowed outside for recess, PE or other activities of 10 minutes or longer duration when temperature and/or wind chill is below 32 degrees Fahrenheit.  Please be sure that students dress accordingly for outside temperature.The following suggestions are reminders to help students with comfort and safety during the hottest times of the year:
Keeping it Cool

       Drink fluids before, during, and after outdoor activities.

       If you feel thirsty, drink fluids!

       If you bring lunch, pack a "Gatorade-type" drink. Sugars decrease the absorption of water by the body.

       Wear loose-fitting, lightweight, light-colored clothing.

Block the Sun

       Wear wide-brimmed hats while in the sun.

       Use a sunscreen with an SPF 15 or greater.

       Stay inside when possible.

       If shortness of breath occurs during vigorous activity, stop the activity and rest in a cooler place.

       Use a buddy system in high-heat activities.

Heat Index - Heat Index (HI) or “apparent temperature” is an accurate measure of how hot it really fells when the relative humidity is added to the actual air temperature. Since heat index values were devised for shady, light wind conditions, exposure to full sun can increase HI values by up to 15 degrees.

Ozone – The “ozone season” runs from May 1 through October 31. Ozone alerts are issued as an “ozone watch”, usually the day before. If conditions actually reach hazardous levels at one of the many monitoring stations around the metroplex, an “ozone warning” is issued for that area. Unless an orange or red “warning” is issued for Collin County, the health of our students is not compromised.


With flu season upon us, it is important that we work together to keep our children and school healthy. By keeping our children flu-free, we benefit the community as a whole. Additionally, healthy students miss fewer days of school, which results in less stress on the family. Following are answers to frequently asked questions about the flu and how to help protect your child.


  • According to the Centers for Disease Control and Prevention (CDC), the best way to prevent your child from getting the flu is to take him/her to get a flu vaccine
  • You should talk to your child about practicing good health habits, such as:
  • Washing hands frequently with soap and warm water for at least 20 seconds
  • Covering mouth and nose with a tissue when sneezing or coughing, and disposing of the tissue in a proper trash receptacle
  • Avoiding sharing drinks, water bottles or silverware with others
  • You can help prevent the flu from spreading at home by disinfecting frequently touched surfaces, toys and other commonly shared items
  • Also, if someone in your household gets the flu, a doctor can prescribe a medication – called an antiviral – that can actually prevent other members of the household from catching the flu
  • Studies show that some antiviral medications are up to 89 percent effective in preventing the flu when taken once daily for seven days.


  • If you are concerned about your child’s flu symptoms, call your doctor early. Call your doctor immediately if your child has a chronic disease.  Some children may benefit from an antiviral medication, which can be prescribed by a physician and can help lessen the duration of the virus and reduce the risk of complications, such as pneumonia
  • To be effective, antiviral medication should be taken within 12-48 hours after flu symptoms begin
  • If your child has the flu, it is important for them to stay home from school, rest, and drink plenty of fluids
  • Additionally, notify the school nurse if your child has the flu. Monitoring flu incidence at Hart Elementary will help keep students, faculty and our community healthy.
