Multiple Choice

Based on this information, what is Kendrick's next step?

• share his results with other scientists

• analyze the data he has collected and draw conclusions

• conduct the investigation and collect data

• repeat the investigation to make sure his results are valid

Take a LOOK!

After creating a hypothesis, it is time to GET TO WORK!

Multiple Choice

The data that Kendrick collected is in the chart above. Now that Kendrick has collected the data, what is his next step?

• share his results with other scientists

• analyze the data he has collected and draw conclusions

• conduct the investigation and collect data

• repeat the investigation to make sure the results were valid

LOOK CLOSER!

After collecting all of the data, you need to ANALYZE that data...figure out what it all means!

Multiple Choice

Which answer BEST describes the discovery of safety glass?

• the discovery is not valid because the scientist was not originally investigating safety glass

• the discovery is valid because it was done by a scientist while working in a lab

• the discovery is not valid because the scientist did not use all of the steps in the scientific method

• the discovery is valid because the scientist made an observation, collected evidence, and conducted more experiments

Look HERE!

The scientist asked himself a question, and then used the scientific method to find an answer!

Multiple Choice

What does Collier Elementary's results indicate about Lee Elementary's results?

• Lee Elementary's results are valid

• Lee Elementary's results are not reliable

• Lee Elementary's results are correct

• Lee Elementary's results are accurate

Look a little CLOSER!

You can see that Collier replicated the experiment EXACTLY. The fact that they did not get the same results, and they repeated the experiment a number of times proves Lee Elementary's data to be UNRELIABLE!

Multiple Choice

How can Yolanda improve the accuracy of her results?

• Repeat the investigation again, but with different types of exercises

• ask a friend to do the same investigation and combine the results

• repeat the investigation but do each exercise for 60 seconds

• repeat the same investigation several times and average the results

Multiple Choice

Yolanda analuzed the results of her investigation and concluded that jogging in place for 30 seconds is the best exercise it increase your heart rate.

For Yolanda's results to be considered reliable, what needs to happen next?

• Other students need to replicate the same investigation and get the same results.

• other students need to jog in place for 30 seconds to compare their heart rate to Yolanda's heart rate

• She needs to jog in place several more times to be sure it is the best exercise

• she needs to tell her teacher

Multiple Choice

Based on the data in the chart, how are the temperature and rainfall data related?

• the data show that when the temperature decreases, there in an increase in rainfall

• the data show that when the temperature increases, there is a decrease in rainfall

• the data show that the temperature and rainfall both increase and decrease at the same times of the year

• the temperature and rainfall data don't seem to be related in any way

TAKE A CLOSER LOOK!

You can see the TEMPERATURE and RAINFALL increasing at the same time!

Multiple Choice

Using this data, students at Collier Elementary decided to conduct a controlled experiment to better understand the water cycle. Look at the four suggestions from students on what the class should do.

Based on the questions and processes each student described, which student's suggestion is the best example of a controlled experiment?

• Johnathan

• Elizabeth

• Manuel

• Joselyn

Let's take a CLOSER LOOK!

Elizabeth's is the best organized for a CONTROLLED EXPERIMENT!

Multiple Choice

Based on the data in the chart, which group MOST LIKELY put their ice cube in the shade?

• Group 1

• Group 2

• Group 3

• Group 4

TAKE A CLOSER LOOK!

It took Group 2's ice cube LONGER to melt...which means it must have been OUT OF THE SUN!

Multiple Choice

Based on the information provided, which class most likely has the most accurate data?

• Friedman's class because their data was the highest average

• Wasmer's class because their data was the lowest average

• Barrett's class because they conducted more trials that the other class

• Barrett's class because their data was in the middle

Take a CLOSER LOOK!

The more trials you have, the more accurate the information!

Multiple Choice

Based on the information, which statement is true?

• A mountain has a lower temperature than a tundra

• Swamps get the same amount of rain as a rainforest

• The amount of precipitation increases as the elevation increases

• The temperature decreases as the elevation increases

TAKE A CLOSER LOOK!

As elevation INCREASES, the temperature DECREASES!

The higher you go, the colder it gets!

Multiple Choice

Based on the information, which statement is true?

• The temperate zone has the highest temperatures

• The polar zones are cold because they are on top of mountains

• As the latitude decreases, the temperature increases

• As the latitude increases, the temperature increases

Let's take a CLOSER LOOK!

The closer that latitude is to ZERO, the WARMER it is!

Multiple Choice

Based on the information, which trial was the control groups?

• The trial with 8 tbsp. of salt

• the trial with 4 tbsp. of salt

• the trial with 2 tbsp. of salt

• the trial with no salt

LOOK!!!

Control groups are what you are comparing your results to!
