Activities & Resources

September= 8/9 Worksheet on metric system

Lab: Mass/vol= ume

Lab handout (mass)
Name _________________                                                              TMS

 

Sci= ence period ________                                                         Date

Lab: mass

 

The= teacher will demonstrate how to use a triple beam balance.

The= teacher will help students with 2  of the 10 problems.  Student will do the rested their own.  Students will find the m= ass of 8 items in group of 3-4 students.

Lab= : Mass
Material: Tri= ple Beam Balance
Procedure:
1. Zero the three slides, one on each rider, on the triple beam balance. 2. Place object gently on the center of the pan.
3. If an object might roll (ex. Marbles), place items in a paper cup and subtract the mass of the cup to find the items mass
4. Slides (largest values, medium values to smallest values)
5. Record the mass (Double check).

Lab: Volume=


Material: graduated cylinder
Procedure
1. Fill a graduated cylinder with 50 ml water   (Initial Measurement)

2. = Place irregular object into the graduated cylinder
3. Record the new measurement (ml) of the graduated cylinder.
4. Subtract the new measurement from the initial measurement and record.
