What is a Good Party for a 11 Year Old?
A mystery party might be a better idea. It would be less violent. Kids of this age love to create things, so craft supplies or a science experiment are good ideas for a party. Make sure to choose activities that are more appropriate for their age, and look for crafts at craft stores. For more ideas, you can search online. You could also hold an obstacle course. Obstacle courses are fun for kids of this age, but you may want to avoid those that can be violent.
Obstacle courses
If your child loves sports, obstacle courses are a great party game for his or her next birthday. Set up the obstacles in the middle of the room or create a course in the backyard, and let the kids race to complete them in the time allotted. The course can be made to include sensory input such as music, sounds and snack stations.

Luau
A Luau party would be a great theme for a girl who loves summertime. It includes leis, coconut bras, and other tropical decorations. She may also enjoy a superhero party, with everyone dressed up as their favorite superhero. This can be very fun. You could even plan a superhero obstacle race with small gifts. There are many ways to have fun at a Luau-themed birthday celebration.
Camping
A camping theme birthday party is the perfect choice for your 11-year old if he loves the outdoors. The theme can be educational and fun and can include activities indoors and outdoors. Your guests can create a nature-themed Scavenger Hunt that they can complete in their spare moments. Print a free printable nature scavenger hunt list and attach it to blank note cards. The camping symbol signs can be attached to plastic binoculars or tin cups. It is easy to throw a camping party. The colors can be earthy and brown.
Science experiments
A great party for a child of this age is filled with fun science experiments. One science experiment involves water and light refraction. Two big arrows placed on large pieces of paper should point in the exact same direction. Slowly lower your arrows into a glass full of water. Watch the arrows floating in the water. Then, add sunscreen to the water and let the kids compare the results. This experiment is perfect for Valentine’s Day.
Outdoor activities
You can organize a field trip with your child if he is a big sports fan. You can also set up an obstacle course for the children and invite them to participate. Water bottles make a great party favor. Another great idea is to have a balloon bullseye. The kids can stick balloons to a vertical surface and attempt to hit the target using a dart.
