How long would it take to hike the Trail of Ten Falls? © Matthew Kuhns/Tandem Stills + Motion Having this up as kids come in is a great settle down activity. You can start class by asking them for thoughts about the picture or about ideas on how they could solve the question of the day.

How long would it take to hike the Trail of Ten Falls? There are at least 17 named falls within Silver Falls State Park in Oregon. The North Falls, seen here, marks the turnaround point for the trail loop known as the Trail of Ten Falls. That 8-plus-mile hike starts at the fairytale-like South Falls, where hikers actually walk behind the cascading waters. (It’s one of four falls along the trail that hikers can walk behind.) Unsurprisingly, Silver Falls State Park is a busy spot from spring through fall. Most of the surrounding forests had been heavily logged by the start of the 20th century. And though many recognized the wilderness’ potential as a possible National Park, the Silver Falls region failed to gain that status. In 1933, it was established as a state park. Two years later, President Franklin D. Roosevelt declared Silver Falls a National Recreation Area, which meant federal funding for more land acquisition and restoration. By 1948, Silver Falls State Park had gained 5,000 additional acres of forest land, more than doubling the park’s acreage. Depending on time, you can either have students read this silently to themselves, have one of them read out loud, or read it out loud yourself.

How long would it take to hike the Trail of Ten Falls? 1 Web Search/Thinking What is the difference between hiking and walking? Why might the pace of the same person hiking and the same person walking be different? 2 Knowing the length of the Trail of Ten Falls, how could you create an equation to determine how long it would take to complete it? 3 This question involves distance, rate and time. What is the distance involved? 4 This question involves distance, rate and time. What is the rate involved? 5 This question involves distance, rate and time. What is the time involved? There are a couple of ways to use this slide, depending on how much technology you have in your classroom. You can have students find answers on their own, divide them into teams to have them do all the questions competitively, or have each team find the answer to a different question and then come back together. If you’re doing teams, it is often wise to assign them roles (one person typing, one person who is in charge of sharing back the answer, etc.)

How long would it take to hike the Trail of Ten Falls? 5 Minutes You can adjust this based on how much time you want to give kids. If a group isn’t able to answer in 5 minutes, you can give them the opportunity to update at the end of class or extend time.

How long would it take to hike the Trail of Ten Falls? 1 Web Search/Thinking What is the difference between hiking and walking? Why might the pace of the same person hiking and the same person walking be different? (Possible Search Queries: “for kids, what is the difference between hiking and walking?”, “for kids, what is hiking?”). From http://www.differencebetween.com/difference-between-hiking-and-vs-walking/: Dictionaries say that hiking is a long walk undertaken for pleasure. This definition certainly equates hiking with walking, but it does not make clear as to when walking becomes hiking. Is it just pleasure, walking in natural surroundings, carrying a backpack on your back that constitutes hiking or there is something more that makes walking hiking? Walking along a beach is still walking and walking on an inclined path in the city is also walking. It has to do with the trails that are unpaved and also with the fact that camping as an activity makes hiking much more interesting and exciting. In the end, it all boils down to the terrain where the person is spending his time that decides whether he is walking or hiking. Students should think about how, because hiking is usually on an incline, and is usually a walk for pleasure rather than to get to a specific destination, the pace at which a person hikes might be slower than the pace at which a person walks. They should keep this in mind as they do their research to arrive at an answer.

How long would it take to hike the Trail of Ten Falls? 2 Web Search/Thinking Knowing the length of the Trail of Ten Falls, how could you create an equation to determine how long it would take to complete it? (Possible Search Queries: “for kids, equations based on distance, rate and time”, “for kids, how to create an equation”). Students should either find an equation online or think logically about how they would create one. They know from the image description that the Trail of Ten Falls is 8 miles so this question is asking them to solve for how long it would take a person to walk 8 miles. Students should determine that if they know how long it takes a person to walk 1 mile, they could then multiple this by 8 to find the total. Exact answers will vary. For example: 8 miles x Pace it takes to Hike 1 Mile = Total Length of Time it would Take to Hike the Trail of Ten Falls. They can then fill in these unknowns with letters. For example: 8 miles x R = T

How long would it take to hike the Trail of Ten Falls? 3 Web Search/Thinking This question involves distance, rate and time. What is the distance involved? (Possible Search Queries: “for kids, equations involving distance, rate and time”, “for kids, distance rate and time”). Students should first search for an equation involving distance rate and time. For example, from http://mathforum.org/dr.math/faq/faq.distance.html: Distance = Rate x Time Rate = Distance / Time Time = Distance / Rate They should then figure out what the “distance” involved in this situation in. They should know from the image description that the Trail of Ten Falls is 8 miles long. This means our total Distance = 8 miles.

How long would it take to hike the Trail of Ten Falls? 4 Web Search/Thinking This question involves distance, rate and time. What is the rate involved? (Possible Search Queries: “for kids, equations involving distance, rate and time”, “for kids, distance rate and time”, “how long does it take a person to walk a mile?”). Students should first search for an equation involving distance rate and time. For example, from http://mathforum.org/dr.math/faq/faq.distance.html: Distance = Rate x Time Rate = Distance / Time Time = Distance / Rate Students should then search for how long it takes most people to walk 1 mile in order to determine what their rate is. For example, from http://www.wereyouwondering.com/how-long-does-it-take-to-walk-a-mile/: Obviously, the answer depends on how fast you walk, but the average person, walking without children can walk a mile in about 20 to 30 minutes. Students can then average this as 25 minutes. In other words, our rate in this equation is 25 minutes.

How long would it take to hike the Trail of Ten Falls? 5 Web Search/Thinking This question involves distance, rate and time. What is the time involved? (Possible Search Queries: “for kids, equations involving distance, rate and time”, “for kids, distance rate and time”, “how long does it take a person to walk a mile?”). Students should first search for an equation involving distance rate and time. For example, from http://mathforum.org/dr.math/faq/faq.distance.html: Distance = Rate x Time Rate = Distance / Time Time = Distance / Rate Students should understand that in this scenario, time is what we are solving for. In other words, we will want to use the following equation: Time = Distance / Rate. We’ll want to find how long it takes to hike a mile so that we can then determine how long it would take to walk the number of miles that make up the Trail of Ten Falls.

How long would it take to hike the Trail of Ten Falls? Students should pull together the information they have gathered to create and solve an equation. The total distance of the Train of Ten Falls is 8 miles and it takes the average person approximately 25 minutes to walk one mile. Therefore, they will want to solve the following: 8 miles x 25 (minutes per mile) = 200 minutes. Therefore, it would take 200 minutes to walk 8 miles (25 x 8). Students can then take this a step further and divide 200 by 60 in order to determine that 200 minutes is equal to 3 hours and 20 minutes. It would take approximately 3 hours and 20 minutes to hike the Trail of Ten Falls.
