APES 9/28 & 9/29Log in to a computer and prepare for a warm-up!

Warm-Up 9/28 & 9/29

• Explain it to me like I’m 5:What is soil salinization?Why is it bad for humansin the long run?

Riverside, California!

Learning Targets

• I can design and carry out a valid experiment to test the effect of salinity on seed germination• Manipulated, Responding, and Controlled variables• Experimental Control/Standard

• I can correctly do math problems without a calculator!

Soil Salinization Lab

1. Compare procedures and data tables as a group.2. Decide on the perfect ones! Your group will only turn in one lab

report. 3. Proceed with your experiment (Set up? Data collection? Checking

on seeds and giving them more time?)4. Ignore the last page of the handout. See lab report requirements

on the next slide.Your lab will be due as one shared Google doc on Sunday at noon.

Lab Report Requirements

1. Testable Question including MV and RV2. Hypothesis3. Procedure detailed enough that I could do it without help4. Data table5. Graphical representation of effect of soil salinity on seed germination

(bar, line- whatever you like)6. CLEVR conclusion

1. Claim = what was your hypothesis? Was it correct?2. Evidence = at least 2 pieces of data to support your claim3. Reasoning = why did your data turn out this way? (i.e. why would certain

salinities affect seed germination in the way they did?)

APES Math Review

• Read each section and work through the packet• No calculators!• You only have to do the last 2 graphing ones (last page)• You will be given work time all 3 class periods this week for the packet

and/or the Chapter 2 Reading Guide.
