Here are some Viking-themed activity ideas for high school students that are engaging and educational:

### **Outdoor Activities**
1. **Viking Obstacle Course**: Create an obstacle course inspired by Viking challenges, such as carrying “shields” (trash can lids), throwing “axes” (foam or cardboard axes), or navigating “stormy seas” (balance beams).
2. **Shield Painting Competition**: Provide wooden or cardboard circles and let students design and paint their own Viking shields.
3. **Viking Games**: Play traditional Scandinavian games like *Kubb* (a Viking lawn game) or adapt games like tug-of-war as a "Viking strength contest."

### **Indoor Activities**
4. **Rune Writing Workshop**: Teach students about the Elder Futhark alphabet and have them write their names or secret messages in runes on stones or paper.
5. **Viking Mythology Trivia**: Organize a trivia session focusing on Norse mythology, Viking history, and famous figures like Thor or Ragnar.
6. **Build a Viking Longship**: Use craft supplies (like popsicle sticks, paper, or cardboard) to build small Viking ships. Add a competition for the most creative design.

### **Creative Projects**
7. **Viking Storytelling**: Encourage students to create their own sagas or write a short play about Viking life, battles, or mythology.
8. **Viking Feast**: Have students research Viking food, then organize a potluck or cook Viking-inspired recipes like flatbread or stews.
9. **DIY Viking Costumes**: Provide supplies like fur scraps, felt, and rope for students to create Viking-themed outfits or accessories like helmets and arm rings.

### **Team Challenges**
10. **Treasure Hunt with Runes**: Design a scavenger hunt where each clue is written in runes or tied to Norse mythology.
11. **Viking Chess Tournament**: Introduce *Hnefatafl*, a Viking strategy board game. Teach students the rules and host a tournament.
12. **Build a Mini Viking Village**: Divide students into groups and assign them different roles (e.g., blacksmith, shipbuilder) to design a miniature Viking settlement.

### **Learning-Focused Activities**
13. **Norse Mythology Debate**: Divide students into teams to debate who the greatest Norse god or goddess was, using evidence from mythology.
14. **History Reenactment**: Reenact a historical Viking battle or raid, with roles assigned to students as warriors, villagers, or storytellers.
15. **Viking Weapons Demonstration**: Research Viking weapons and tools. Make foam replicas and discuss their design and use in battles.
