Evaluate Other's Work Lab Report
Question 1: Evaluate Other's Work Mrs.Leonardos' conclusion and her overall experiment has some limitations.For example, she doesn’t have a hypothesis or a clear independent variable that was supposed to be in her question.According to her chart, the densities of the 2 clays are not different by about .2 g/cm3 which means that the kind of clay that she is using might be different which can make the experiment have 2 independent variables (size and the type of clay).This will make the experiment uncontrolled which will not yield any reliable data.Also, according to her conclusion, she has no evidence from text and/or her data table.
Question 2: Formulate a Testable Question How does the size of the pieces of modeling …show more content…
Question 4: Procedure
Materials: Graduated Cylinder, Red Modeling Clay, Triple-beam Balance, Calculator
1)Cut the red modeling clay into 3 pieces with different sizes (small,medium,and large)
2)Create a data table that includes 4 sections (Clay size,Mass,Volume,Density) and it needs to include trials (1,2,3)
3)Measure the small piece of clay's mass using the triple-beam balance,and record the result on the data table for small sized clay, and use units to the tenth place.
4)Measure the volume of the small piece of clay using the graduated cylinder and record it under the volume section for small sized clay (record to the tenths)
5)Then, use the calculator and find the density of the small clay by using the formula D=M/V,and record on the data table (unit is g/cm3 and also to the nearest tenth)
6)Repeat 3 to 5 with medium and large …show more content…
The one isolated variable in the experiment is the size of the clay pieces while all other variables like the color of the clay were all kept constant. According to Mrs.Leonardos' data table, the 2 densities does not have similar densities which means that something in her experiment is affecting the density of the different sized clay pieces (like kind of clay which can be one of the factor that is making her experiment uncontrolled). In her question, the independent and the dependent variables are not clear. She had no hypothesis or rational and her procedure didn't include materials needed for the experiment. Another negative factor of her experimental design is her conclusion, she didn't use evidence from her chart or textual evidence from the article either. In my experiment, the densities were close together, I had clear independent and dependent variable in my question which is the size of the modeling clay and the densities of clays. My experiment also has a hypothesis and a vaild rationale, in my conlusion, I had textual evidence and details from my data
