Hit the Target Notes
Notes:
Teaching Ideas and Suggestions:
The interactive is restricted to horizontally-launched projectiles. There are four activities. In the first three activities, students solve two similar problems of the following types:
- Activity 1: Given launch height and vox, solve for the horizontal displacement.
- Activity 2: Given horizontal displacement and vox, solve for the launch height.
- Activity 3: Given horizontal displacement and launch height, solve for the vox.
All numbers are randomly generated. Students enter their answer and tap on a Fire Cannon button. If solved correctly, the launched projectile will hit the target. If not solved correctly, then the projectile will miss the target and a screen outlining the problem-solving approach is displayed. Once the first problem is solved, a second problem is presented. Two successes returns the student to the Main Menu where he/she can procede to the next activity. Student progress is kept track of using a system of stars and trophies. Student answers are considered correct if they fall within 2% of the correct answer. Thus, students should avoid excessive rounding and use three significant digits in their answers.

- Minds On Physics Internet Modules:
The Minds On Physics Internet Modules include a collection of interactive questioning modules that help learners assess their understanding of physics concepts and solidify those understandings by answering questions that require higher-order thinking. Missions VP7, VP8, VP9, and VP10 of the Vectors and Projectiles module provide great complements to this Interactive. They are best used in the middle to later stages of the learning cycle.
