Pg. 12 RTW: Do you know what KHDMDCM means?
Objective: I will be able to measure different objects using a variety of different tools.
Agenda:
TURN IN TURTLE GRAPH
Measurement Lab
Homework:
None 
DO NOT TOUCH MATERIALS ON THE DESK. BAGS UP FRONT DURING LABS! You will need your notebook and a pen/cil

2. How many jumps does it take?
Ladder Method 1 2 3
KILO 1000 Units
HECTO 100 Units
DEKA 10 Units
DECI 0.1 Unit
Meters Liters Grams
CENTI 0.01 Unit
MILLI Unit
How do you use the “ladder” method?
1st – Determine your starting point.
2nd – Count the “jumps” to your ending point.
3rd – Move the decimal the same number of jumps in the same direction.
4 km = _________ m
Starting Point
Ending Point
How many jumps does it take? 4. 1
__. 2
__. 3
__.
= 4000 m

3. Conductivity Station For Conductivity station:
Measure conductivity of salt water
Measure conductivity of the fresh water
*If the number doesn’t stabilize quickly count to 5 and record that number*
**Remove probe from the beaker before leaving the station**

4. Temperature #1 Station For Temperature probe:
To change the units, use the stylus to click on the number, click “Change Unit”, and choose the appropriate unit
**Remove probe from the beaker before leaving the station**

5. Temperature #2 Station For the Temperature #2 Station:
Use the IR thermometer “gun” to record the temperatures of the items listed
You can change the units using the button below the screen
Be sure to write down what unit you use
**DO NOT POINT LASER INTO EYES!**

6. Volume Station For Beaker and Graduated Cylinder:
Measure from the bottom of the meniscus
Is one method more precise or accurate? Why or why not?

7. Density Station For the Density Station:
Use the equation given on the sheet
The mass of the book is 5.24 lbs
BE SURE TO WRITE THE UNIT OF MEASURE

8. Weight Station For the Weight Station:
Reset the station when you are done, removing the items from the scale and “zeroing” it out

11. ShORE Symposium If you’d like to present your proposal:
HONORS
ShORE Symposium
If you’d like to present your proposal:
SEE ME AFTER CLASS ABOUT DETAILS
I will be giving you the opportunity to come on a field trip to the ShORE Symposium to see current research being done in the Indian River Lagoon (FRIDAY, DECEMBER 1ST)
First come, first serve: those who don’t come will have an alternative assignment

12. Salinity Concentration
Nemo= Tap water
Marlin = 0%
Dory= 0.25%
Bruce = 0.5%
Gil = 0.75%
Gus = 1.0%
Sheldon = 1.5%
Peach = 3.5%

13. Mung Bean Experiment Read Australia’s Salinity Crisis
Set up experiment with assigned saline solution
You will need:
Rough Draft Lab Report
Petri dish
2 paper towel circles
Cup of 20 mung beans (make sure you count them)
Paper slip
Pen/cil

14. Salinity Concentration:
Procedure
Place the paper towels into the bottom of the Petri dish
Use the pipette to moisten the towels with your assigned saline solution
Arrange your mung beans on the paper towels so that they are evenly spaced out and not touching one another
Create a label
Place Saran wrap over dish and use tape to stick label to your dish
Place your dish on the counter on the right side
Name:
Date:
Salinity Concentration:

15. Rough Draft Lab Report Title : Background:
Write a brief statement or question that describes the main point of the experiment.
Background:
give the reader information about salinity and it’s affects on plants (refer to what you read in the article)
Experimental Question: Will mung beans sprout with various salinity concentrations?

16. Rough Draft Lab Report Hypothesis:
Write 2 sentences to a paragraph that includes (1) the hypothesis and (2) a justification of the experiment.
A hypothesis is an educated guess about how things work.
Most of the time a hypothesis is written like this: "If _____[I do this] _____, then _____[this]_____ will happen." ...
Your hypothesis should be something that you can actually test, what's called a testable hypothesis.

17. Rough Draft Lab Report Materials:
List everything needed to complete the experiment.
Mung beans
500 mL beakers
Paper towels
Petri dishes
Salt
Digital scale
Scissors
Labels
Pen/cils
Pipette 10 mL
Cups
Tape

18. Procedure: Describe the steps you completed during your investigation in great detail (more detail than here).
Count 20 mung beans
Measure salt in grams based off concentration calculations
Measure 500mL of water
Label each beaker with the concentration %
Pour salt into water and mix well ….
