Clyde notices that a television commercial he regularly watches advertises a laundry detergent for its ability to make white clothes brighter than when using any other detergent. How can Clyde determine if the laundry detergent being advertised is capable of making whites brighter?
Clyde needs to know that all information advertised on television commercials are true
There is no need for Clyde to test this claim because all brands of detergents clean the same
Clyde can compare different brands of detergents with the one advertised to see which one cleans whites best
Clyde can compare different pieces of white clothing after washing them with the advertised detergent

As Mollie prepared to place all her written parts on her science board, she noticed that one part was not labeled. Mollie could not use her science fair packet to determine which part of the experiment it belonged to because she had left it in her desk at school. Mollie then decides to call a classmate to read her the unlabeled part to see if she could help her determine where it should fit on the board.
Unlabeled part: Brand A diapers absorbed 10 ml more water than Brand B and 16 ml more water than Brand C diapers. It was interesting to see how Brand C diapers began to come apart after only a few minutes of soaking in the water.
The unlabeled part must be the conclusion
The unlabeled part is the results of the experiment
The unlabeled part must be a part of the materials
The unlabeled part is the hypothesis

3 different cities for collecting and measuring acid rain
The acid level of the rain collected in Phoenix, Arizona
The constant variables in an experiment are held the same throughout the experiment. For example, the constant variable may be the height and angle of a light source above plants being grown. Which of the following represents constants/controlled variables?
Selecting 3 different temperature settings during experimentation
Measuring blocks that have the same mass, the same wood type, using the same measuring device
Pennies collected from 2000-2009 and pennies collected from 190-1999
The time it takes for ice cubes to melt when left in an area with increased temperatures
Which of the following would MOST LIKELY represent a control group?
Group 1: Bean plants grown in soil used for many years

Group 4
A class made models of a graduated cylinder using plastic cups. Which of the following describes the first step the class can use to test the accuracy of the classroom models for measuring volume?
Pour 7 ml of water into a graduated cylinder & another 7 ml of water into the classroom models
Pour 7ml of water into a graduated cylinder and transfer the 7ml from the graduated cylinder into one of the classroom models
Pour 7ml of water into a graduated cylinder and transfer the water equally from the graduated cylinder into all of the classroom models
Pour 7ml of water into a graduated cylinder and different amounts of water into each of the classroom models
Seth designed an experiment to see if butterflies preferred a particular color while feeding. He used 4 different colored sponges, which he soaked with a nectar-like substance to attract the butterflies. Seth made the following observations for 3 hours each Saturday over a one-month period & recorded them in the chart. What conclusion can be made using the data collected based on Seth's observations?
Color does not matter to butterflies when they are hungry
Butterflies prefer blue while feeding
Butterflies prefer the colors red or green when feeding
Butterflies prefer yellow while feeding
Daniel learned that many ants feed on certain sweet liquids left behind by other insects called honeydew. Daniel decides to investigate ant food by conducting an experiment to see if ants are more attracted to honey than sugar. The results of Daniel's findings are listed. Which statement is the BEST conclusion to draw from Daniel's recorded results?
The ants are more attracted to sugar
The ants are more attracted to honey
The ants are not attracted to sugar or honey
The ants equally like sugar and honey
Marc's mother noticed that his feet seemed to be growing at one shoe size per year. Out of curiosity, she decided to record his shoe size each year on his birthday. What mistake did Marc's mother MOST LIKELY make in her measurements?
Marc's mother most likely measured his feet twice per year
Marc's mother made inaccurate measurements in the year of 2007
Marc's mother made inaccurate measurements in the year of 2008
Marc's mother stopped measuring her son in 2009
Chloe wants to know if caterpillars prefer eating decaying old leaves or new leaves just picked from the tree. She takes some cuttings of a plant and combines one set with new leaves and another set with old leaves. She then places the cuttings of the lant, combined with leaves, on opposite sides of a bed of soil. The caterpillars she has collected are placed in the middle of the soil bed, an equal distance from both sets of cuttings. In order to record the results, what should Chloe do next?
Research which type of food caterpillars prefer
Repeat the experiment with worms or bugs
Record the number of caterpillars that remain somewhere in the soil
Count & record the number of caterpillars that feed off of each set
The science lab for the week was to investigate the effect of color on heat absorption. The class decided to compare heat absorption using the color black as compared to the color white. The results of four of the five lab groups indicated that more heat is absorbed by the color black. What should the lab groups do to determine why one group got different results?
All groups should immediately try the experiment again
Compare the procedures of the one group to the other four groups
The group that concluded that white colors absorb deserve a failing grade
Change the data of the group that had different findings to match the others
Ava crated an experiment to see if apple cider vinegar, when added to baking soda, releases more gas bubbles than when added to white vinegar. Which statement BEST describes why Ava should write down her experimental procedure?

The result will help consumers decide which vinegar to purchase
To allow other researchers to understand why she selected her hypothesis
So that experimenters may repeat the exact scientific investigation
