Grade 6 Science SPRING ENRICHMENT PACKET

What conclusions can be drawn about the results from Ms. Castillo’s investigation?

• The students should drink water before the test.

• The students should drink water with a peppermint before the test.

• The investigation yielded unreliable results because it had more than one independent variable.

• The investigation yielded reliable results because it had an independent variable and dependent variables.

You have run several trials in your experiment and gathered data from each trial. What will help you organize all the information from your experiment?

• develop a hypothesis

• create a table or a graph

• run some more trials

• draw your conclusion

Use the information below to answer Number 3. Students counted the number of chirps made at different temperatures in 13 seconds by the same group of snowy tree crickets. The students recorded the data in the table below. One student concluded that at 22°C there would be 39 chirps. The student’s conclusion is most likely invalid because:

• the investigation contains two variables

• the data does not support the reasoning

• the number of crickets studied was too small

• the species of crickets used is not usually studied

Use the information below to answer Number 4. In general, coastal dolphins seem to be adapted for warm, shallow waters. These dolphins frequently harbor, bays, lagoons, and estuaries. Dolphins that live near the Maryland coastline are often observed in water temperatures between 10° Celsius and 32°Celsius. The number of dolphins counted during several years is shown in the graph below. Which year most likely had temperatures between 10° Celsius and 32°Celsius for the longest amount of time?

• A. 2005

• B. 2007

• C. 2009

• D. 2010

The scientists working at the Integrated Ocean Drilling Program are most likely

• 1. researching the structure of the planet.

• 1. looking for more information about ocean food webs.

• 1. investigating how fish live in the depths of the ocean.

• 1. trying to understand how the ocean influences weather.

The Integrated Ocean Drilling Program scientists hypothesized that drilling at the Atlantis Massif would

allow scientists to collect rocks from the mantle of Earth.

Explain why scientists make a hypothesis. In your explanation, be sure to include:

• the importance of a hypothesis

• what might be learned from an incorrect hypothesis

• supporting evidence from this investigation
