Hit The Target Lab

My physical scientific discipline students actually enjoyed this "Hit the Target" Lab.  It's my commencement fourth dimension educational activity physical science, as well as I'm learning as well as then much every day.  When I typed upwardly this mini-lab sheet, I reckon nosotros would hold upwardly able to calculate the mistake as well as per centum error.  I didn't mean value through this really good because my students started having problem when they went to figure their per centum error.  Oops.  I LOVE this lab.  But, it needs some major editing for adjacent twelvemonth to arrive to a greater extent than effective.

Here's what nosotros glued inwards our interactive notebooks:

This gave me a adventure to debut my novel accuracy as well as precision posters.  I've blogged well-nigh these posters here.

I printed off some targets from this website.  The file suggested having students drib a colored marking onto the target.  I modified this past times laminating the targets using my trusty laminator.  Then, my students proceeded to crouch on their knees as well as drib a dry out erase marking on the target v times.  My favorite dry out erase markers to purpose alongside students are these pen agency dry out erase markers that are made past times Universal.  If you lot store roughly as well as toll depository fiscal establishment gibe alongside other sites (I've oftentimes establish them the cheapest at Shoplet or Zerbee), you lot tin become them for roughly $2.00/dozen!

When nosotros dropped the dry out erase markers, they actually did acquire out a dot on the target.  I was a fleck skeptical well-nigh this working, exactly it did!      

Here's a educatee well-nigh to drib his dry out erase marking on his target.  (Full disclosure: I insisted that he intermission patch I took a picture!)

After students had dropped their marking on the targets v times, students had to sketch the dots on their mini targets for their notes.

Next, students had to mensurate how far each betoken was from existence inwards the bulls eye.

This is in all probability the house inwards the lab where I messed up.  I had students mensurate how far the betoken was from existence inwards the bulls eye.  So, if a educatee had iii of their dots halt upwardly inwards the bulls eye, the distance for these points would hold upwardly 0 mm.

Students had to average their v distances from the bulls eye.  From this average, they were able to calculate their precision as well as their error.  The occupation arose when nosotros went to calculate per centum error.  The actual value nosotros were aiming for would hold upwardly 0 mm, exactly nosotros couldn't separate past times 0 mm without getting an undefined answer.

Should I bring had my students count how many landed inwards the bulls optic vs how many didn't?  I didn't develop the mini-lab this agency because

I dear the reckon behind this lab.  But, it needs a lot of operate to hold upwardly a to a greater extent than effective activeness inwards the classroom.  Hopefully this postal service gives somebody an reckon for their classroom.  Sorry I don't bring ALL the answers!  ;)

The notebook page I created for this activeness tin hold upwardly establish here.
