Curated OER
Walking on Water
High schoolers use this problem to help them to relate to force vectors: Suspend a meterstick horizontally between two tables. Place a 1kg mass in the middle of the meterstick. Notice the bend of the meterstick. Explain why the...
Curated OER
Waterskiing in Circles
Young scholars discuss and give examples of Newton's three laws. They then answer questions in reference to Newton's three laws. One example of the questions that students answer is: A water-skier typically uses a 75 foot tow rope. The...
