-African Delegate At Johannesburg,.  World Summit, 2002  (Rio +10)

Notes – You Can Use for All Science Units!

I. Claim Evidence Reasoning – CER With Reproductive, Behavioral and Physical Traits

II.  Types of Experiments!

A.  Control:

1. This experiment does not have any changes added.
2. This is the experiment that all others are compared to
3.  ex.:  think about the Flower Lab example we talked about in class.  The Control experiment was the flower placed only in water (no substances added).

B.  Independent Variable:

1.  The changed factor that you want to test
2.  The one change that is different from the control experiment.
3.  Change only one independent variable at a time.
4.  Equal amounts of the variable must be added
5. ex.:  think about the Flower Lab example we talked about in class.  The Independent Variable were the different substances added to the flower’s water.

C.  Dependent Variable:

1.  The measurable results
2.  These may change in each trial

III. Lab Safety –

STEM ENGINEERING!

IV. STEM – Engineering Design Process.

{The notes below – are short summaries of each section of the EDP. Students in each class referred to the “STEM EDP Box Paper” Students noted details on their paper. The entire process is detailed and described on the

STEM EDP page on this Blog.

ASK – State the key question or the key problem in the investigation. The Point or Purpose of the Experiment.

IMAGINE – Brainstorm solutions for the problem; form a Hypothesis; make a Claim

PLAN – Draw a diagram of the experiment or model; list Materials (use metric units); list a Method (Procedure)

 CREATE – Run Trials (tests); Record Data on Graphs, Tables or Charts; Data must be measurable

IMPROVE – Changes made to the Materials or Method or experimental set-up; run extra trials. May re-visit any of the previous steps.

SHARE & COMMUNICATE – talk and listen to other groups; talk /listen to your teammate; talk about Data/Results; ………. note how science concepts relate to data
