QR Challenge: Rainforest Fact Cards

Created using the ClassTools QR Treasure Hunt Generator

Teacher Notes

A. Prior to the lesson:

1. Arrange students into groups. Each group needs at least ONE person who has a mobile device.

2. If their phone camera doesn't automatically detect and decode QR codes, ask students to

• Download a QR reader (e.g. I-Nigma | NeoReader | Kaywa) onto their mobile devices
• Bring these devices into the lesson.

3. Print out the QR codes.

4. Cut them out and place them around your class / school.

---

B. The lesson:

1. Give each group a clipboard and a piece of paper so they can write down the decoded questions and their answers to them.

2. Explain to the students that the codes are hidden around the school. Each team will get ONE point for each question they correctly decode and copy down onto their sheet, and a further TWO points if they can then provide the correct answer and write this down underneath the question.

3. Away they go! The winner is the first team to return with the most correct answers in the time available. This could be within a lesson, or during a lunchbreak, or even over several days!

Questions / Answers (teacher reference)

Question	Answer
1. #1 Tropical rainforests are biomes. A biome is an area with very distinctive plants and animals that have adapted to life in that particular enviromnent.
2. #2 Rainforests have covered large portions of Earth for millions of years, and can have trees that are 1,000 years-old or more.
3. They are called rainforests because they are among the wettest areas on Earth. Nearly all rainforests get over six feet of rain per year. Many get more than sixteen feet of rain and some get as much as thirty feet!
4. #4 In most rainforests, the temperature ranges from 70 to 85 degrees Fahrenheit all year long. The air is almost always humid.
5. #5 Rainforests have four distinct layers of trees. They are the emergent layer, canopy, understory, and the forest floor.
6. #6 The emergent layer has giant trees growing from 100 to 240 feet tall. These trees have umbrella-shaped crowns that grow high above the rest of the forest and are home to many animals.
7. #7 The canopy has trees that grow up to 130 feet tall. They form a tight covering over the rest of the forest which allows very little sunlight to come through.
8. #8 About 90% of all rainforest animals live way up high in the canopy.
9. #9 The understory is very shady. About 15% of sunlight falls through the canopy to the understory. It tends to be very warm and humid here.
10. #10 Only trees and leafy plants that require little sunlight can grow in the understory. There are many smaller shrubs, vines, animals, and insects here, but little air movement!
11. #11 The forest floor is surprisingly dark because only 2% of the sun's light reaches this area. There is very little plant life on the forest floor. It's covered with fallen leaves, seeds, dead flowers, and fruits.
12. #12 Rainforests produce about 40% of the world's oxygen.
13. #13 About 25% of all medicines come from rainforest plants.
14. #14 One thousand four hundred plants in the rainforest are believed to offer cures for cancer.
15. The biggest tropical rainforest is the Amazon Rainforest in South America. The Amazon is bigger than the states of Texas, California, Colorado, Florida, Nevada, Arizona, Oregon, Minnesota, and Alaska combined!
