Dear Mr. and Mrs. Clark,
We are writing to tell you about a field trip for the students of Class 5B. On Friday, May 23, the class will visit the City Science Museum to learn about space and the natural world. We believe that this trip will be both fun and educational for your child.
The students will travel to the museum by bus. They should arrive at school by 8:30 a.m. as usual, and the bus will leave at 9:00 a.m. We expect to return to school by 3:00 p.m., so children can go home at the normal time. Please make sure that your child wears comfortable shoes and brings a packed lunch and a drink.
There is no charge for the museum itself, but we ask each family to pay $5 to help cover the cost of the bus. Please send this money to your child's teacher by May 16. If paying is difficult for your family, please contact us, and we will find a solution together.
Finally, please sign the form attached to this email and return it by May 16 to give permission for your child to join the trip. We also welcome a few parents to join us as helpers on the day, so please tell us if you are interested. If the weather is very bad, we may move the trip to the following week, and we will contact you straight away if this happens. Thank you very much for your support.
Best regards,
Ms. Hill, Class 5B Teacher
