Protocol

Materials

-wooden block with different surfaces

-Ramp

-String

-spring balance

Steps

1. Attach the block to the string
2. Attach the STRING TO THE SPRING BALANCE.
3. PLACE THE RAMP ON EITHER A FLAT SURFACE OR HAVE IT INCLINED AT AN ANGLE.
4. CONTINUE ADDING 10g weights until the wooden block move
5. record down the reading ON THE SPRING BALANCE  AND THE WEIGHT IN A TABLE
6. rEPEAT THE EXPERIMENT TWO MORE TIMES And find the average oF THE RESULTS
7. tHEN DRAW A CONCLUSION

- Do not type in CAPs. It's equivalent to shouting. Please control the font size as well

- There is no spring balance. The weights are already weighted and the mass indicated on them

 Aim: 

 Find out what is the minimum of force needed to pull the wooden block when it is placed on different surfaces.

Protocol:

1. Put a wooden block on top of the long wooden plank.
2. Attach a string  to the wooden block
3. Put the string over the pulley.
4. Attach weights onto the other end of the string until the block moves.
5. Record the amount of weights on the other end of the string in a table
6. Repeat steps 1-5 using other surfaces of the wooden block.
7. After doing steps 1-5 five times, conclude which surface needs the least amount of weights to pull it.

Materials:

Weights

Spring + Pulley

Block

Aim: To find out the minimum  amount of force (load) needed to overcome the inertia of the block.

Steps:

1. Attach the spring to the block. 
2. Place the block on the table and place the spring with the pulley.
3. Attach the weight to the other end of the spring. Start with 1 kg.
4. Repeat Step 3 and increase the weight by 5g/10g in succession until the block is just able to moves.
5. Count the number of weights and record it down.
6. Repeat the experiment 3 times to make sure the results are reliable.
7. Take the average number of weights (???) based on the results.
8. Well Done! You have just successfully complete the experiment.

Comments
- Do not use multiple colours in your report. Looks unprofessional. Max colour is 2. Praising is not part of protocol - protocols is a type of information report and must be kept at a formal tone 

Duncan, Ernie, Kelly and Yong Xuan.

Aim:
To find out the minimum amount of force (load) needed to overcome the inertia of the block.
Materials:
A load, a pulley, a surface and a block.
Steps:
1. Put the block on the platform.
2. Tie the string to the block.
3. Apply force to the wooden block by adding weights to the pulley.
4. Add more weight tot he pulley util the wooden block moves.
5. Record the minimum amount of weights needed to move the block.
6. Repeat the experiment a few more times to ensure its accuracy.
7. Draw a conclusion by finding the average of the results obtained in each experiment conducted.

Yong Fu, Yi Da, Ivan, Alison

Aim of experiment: To find out the minimum amount of force (load) needed to overcome the inertia of the block.
(Inertia or reluctance of the object to change its position)

Materials: Block, load, table, string and pulley

Protocol:

1. Connect one end of the string to the block by tying it around the block.

2. Put the block on the table.

3. Put the pulley on the table.

4. Put the string through the pulley.

5. Connect the weights to the other end of the string.

6. Increase the number of weights in 10g succession until the block moves.

7. Count the weights needed for the block to move at the end of the experiment.

8. Repeat the experiment three times to ensure the results are reliable.

9. Find the average of the number of weights needed for the block to move.

Our Protocol (Eason, Travis and Kang Yu)

   Materials

• A Block
• Pulley
• String
• Weights
• Table

     

  Aim/objective: To find out the minimum amount of force needed to overcome the inertia of the blocks.

Step 1 : Set the block on the table surface

Step 2 : Attach the block to the string.

Step 3 : Hang the string over the pulley

Step 4 :  This is the set-up. Attach weights to the string and see how many weights are needed to move it and calculate the total amount of mass

Step 5 : Repeat the experiment 5 times.

Science Protocol (Kee Chew,Jing Le,Yan Ji,Ranen)

The aim of the experiment:to find out the minimum amount of force (load)needed to overcome the inertia of the block.

Materials:

-Force meter

-pulley

-wooden board

-boxes with different surfaces

-weights(10g, 20g, 50g)

-weight hanger

-rope

Steps

1) Place a wooden board at the edge of the table.

2) Attach a pulley to the edge of the wooden board.

3) Hook one end of the rope to the wooden block and pull it through the pulley and let it hang.

4) At the other end of the rope, hang the weight hanger.

5) Continue placing 10g weights in succession at the weight hanger until the wooden block starts to move.

6) Count the mass of the weights.

7) Repeat step 5 and 6 twice more and calculate the average mass it takes for the block to move

8) Plot it into a table 

Science Experiment on Forces (Qin Ying, Amanda, Renesh and Rui Sian)

Aim:

To find out the minimum amount of force needed to overcome the inertia of the wooden block.

Protocol:

1. Place the ramp on the flat surface.

2. Place the wooden block just beside the ramp.

3. Hook the pulley to the block.

4. Add weights to the pulley till it is able to be pulled up the ramp by the force-meter. (Find out the least number of weights needed for each surface e.g. sandpaper, plastic sheet)

5. Take 3 readings per surface.

6. Fill in the table on page 13.

7. Draw a conclusion from the table (also on page 13).
