Notes:

The Hit the Target Interactive is an adjustable-size file that displays nicely on smart phones, on tablets such as the iPad, on Chromebooks, and on laptops and desktops. The size of the Interactive can be scaled to fit the device that it is displayed on. The compatibility with smart phones, iPads, other tablets, and Chromebooks makes it a perfect tool for use in a 1:1 classroom.
 

 

Teaching Ideas and Suggestions:

This Interactive was created for our collection in late December of 2020. A few years earlier we had added two similar Interactives that had more of a storyline associated with them - Turd the Target and Turd the Target 2. The storyline centered around a flock of angry birds whose mission was to soil the football field with ... well ... bird turds. The principal had commissioned her Physics students to protect the turf and adjoining stadium from the ensuing mess using their knowledge of the Physics of projectile motion. While our goal was to add a little excitement to projectile problem-solving by doing a deviation from the Angry Birds theme, it seems that we only proved that we were better at Physics than we were at comedy. While many teachers and classrooms loved it (and still love it), we've heard from many more who wouldn't dare use it because of the ... well ... turds. And so this Interactive was born. There's no storyline. No turds. No drama. No possible embarassment in sight. Just good, old-fashion hit-the-target practice without any chance of a filthy mess. 

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
The fourth activity involves mixed practice, providing one of each type of problem. 

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. 




 

Related Resources

There are numerous resources at The Physics Classroom website that serve as very complementary supports for the Hit the Target Interactive. These include:
  • 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. Visit the Minds On Physics Internet Modules.

     
  • Curriculum/Practice: There is a single Concept Development think-sheet at the Curriculum Corner that would be very useful in assisting students in cultivating their understanding. It is named
