Diana Herrington• Teaches at Clovis High School

• Math & Physics Credentials –Loves to use science to teach math

–2011 CA State Science Fair Coach of the Year

–1999 PAEMST

–CalTAC member

Kendia Herrington• Teaches at Alta Sierra Intermediate

• Chemistry Credential

• Goal:

& enjoy the science around them.– Enable students to see

– Crazy enough to enjoy teaching 8th grade science

What do scientist do for today’s activity?

• Make observations– Look at the sand/geological surface

– Notice similarities and differences

• Ask questions– What do you wonder when looking at the sand/geological surface

or thinking about the investigation

• Make predictions– Based on what you already know about geology, what do you

observe?

– What patterns do you notice that lead you to make reasonable guesses about the sand/geological surface

35

What do scientist do for today’s activity?

• Conduct investigations– How can you find answers to your questions? – Use your senses, tools and conversations with others around you

• Record data– Draw, describe and organize your observations

• Analyze findings– What does your data mean? – What is your evidence to support your explanations?

• Communicate ideas– Share your ideas with others in your group. – Listen to their reflections

Find Your Beach• Adapted from MBA

– http://www.montereybayaquarium.org/lc/teachers_place/resources_teaching_activities.aspx

– http://www.montereybayaquarium.org/PDF_files/teaching_activities/Find_Your_Beach3-5.pdf

• Need some sand, containers, and measuring tools–Ziplock bags work for containers

• Goals–Learn how to measure & use tools

–Discover an average

35

Find Your Beach

Number of grains of sand

Average length of a

grain of sand

5 mm 15 mm10 mm 20 mm

35

Find Your Beach• Discover the average

• Now we get to use our data!Overall Average grain size by the

graph

35

Find Your Beach…Extension

• Time collection or walking–Measure how long it takes to get sand

–Student walking a distance

• Distance with a map–Use locations from river mouth

–Create a Grain Size-Distance Graph

–Create maps in Google Earth • Use walking time to make full story of the trip

35

NASA & Curiosity• Take knowledge from “Find Your Beach”

and apply to Mars

• THEMIS–Mars Thermal Emission Imaging System

• Mars Image Analysis (AMU & NASA)

Crater Canyon Layers

Faults Fissures Sand Dunes

Dust Devils Wind Streaks Channels

35

NASA & Curiosity• Observations on THEMIS images–Sunlight from left

–Scale to determine size (~ 18 km across)

–Geological sections

–Story of time

• Q2 Lab–Qualitative VS Quantitative Data

–End of year, what do they now see

35

End Effector

35

End Effector … Extension

• Measure for ratios–Circumference of effector–Mass of object picked up–Ratio …Circumference: Mass

• Change sections –Longer or shorter string–Thicker or skinner string–Different cups

• Ideas?
