SSA Review Quarter 1

A swimming team needs to choose new swimsuits and they have three different designs to choose from. Each suit is made up of different material. The team decides to do an experiment to determine which material will dry faster. Jayden cuts different size pieces from each fabric, wet each piece with the same amount of water, place each piece in the sunlight and check it every 15 minutes. What did Jayden do wrong?

• Nothing, his experiment was perfect

• He should have cut the same size pieces

• He should have used the same amount of water for each trial

One way to analyze data from a study is to _____________

• make a graph

• develop a hypothesis

• recognize a problem

What conclusion can be supported by the graph

• as time decreases the plant height increases

• as time decreases the plant height stays the same

• as time increases the plant height increases

• as time increase plant height stays the same

A class is collecting data on the temperature change in water compared to different types of soil. Each group is observing the setup in the picture. Two of the groups data is shown. What went wrong with this experiment?

• One group used the thermometer wrong

• The groups were measuring different things for their dependent variable

• The groups did not agree on how to collect the data

Which is the best description of the dependent variable?

• the variable that is changed by the scientist

• the measurable variable

• the variable that does not change

Daniel and Alex are both scientists. Daniel conducts an experiment testing different fuel sources for cars in the future. Daniel conducts each test three times in order to compare his data. After he finishes the trials, Daniel shows Ales his results from each trial. Alex is confused about Daniel's results, so he decides to conduct the experiment for himself. Which scientific process did Daniel perform?

• observe

• repetition

• replication

• check for accuracy

Tanisha wants to learn about the behaviors of the birds in her neighborhood. Which method of investigation would be appropriate?

• observe and record the types of birds and their behaviors in her neighborhood

• research information on different types of birds in the library and on the internet and uses it to determine which birds are most likely to live in her area

• measure out different types of birdseed and place them in her backyard and record which type is eaten the most often

• compare birds in different areas by studying the behavior of birds in her friend's neighborhood and compare it to the behavior of birds in her own neighborhood
