OUR 5TH GRADERS ARE STARTING WITH

CONTROLLED STUDIES

************************************************************

5 - Muldoon/Strang

"Alka Seltzer"

  

 

                   

            Ms. Muldoon's class did a controlled study with Alka Seltzer.

 

      

                 

   They measured the dissolving rate in different temperatures of water.

 

 

               

               They used hot, room temperature, and cold tap water.

 

       Which do you think dissolved the Alka Seltzer tablet the fastest?

5-Qui

Sets up a Controlled Study

 

             

                           Ms. Quinones' class set up their own

                           controlled study using a ball and ramp.

   

                 

                         What effect will the height of the ramp

                      have on how fast the ball will travel down it?

   

            

                                    Every group did three trials.

 

           

 

Do you think the height made a difference on how fast the ball went down?

Ms. Reid/Livermore's Class

 

        

      Ms. Reid's class has been looking at slides under the microscope.

 

       

                              They made their own cheek cell slides.

 

      

 

            They looked at their cells under low power and high power.

                                          5 GRAF/LIVERMORE
                           INVESTIGATES A MYSTERY POWDER


         
                          OUR STUDENT SCIENTISTS HAD A CHANCE TO 
                                          NVESTIGATE A MYSTERY POWDER.

        
               FIRST THEY MEASURED 1.2 ml OF THE MYSTERY POWDER
                                              AND PUT IT IN THE BEAKER.

       
                     THEN THEY MEASURED 30ml  OF TAP WATER AND 
                       ADDED IT TO THE MYSTERY POWDER AND STIRRED.
                              THEY RECORDED THEIR OBSERVATIONS.

        
         AFTER THE INVESTIGATION, THEY ADDED 60ml OF WATER  TO THE
                                        MYSTERY POWDER AND STIRRED.
                                 THEY RECORDED THEIR OBSERVATIONS. 
      THEY KEPT ADDING 6Oml OF WATER UNTIL THEY REACHED 270 ml.
 
                                

                            THEN THEY RECORDED THEIR CONCLUSION.
