Unit A Study Guide

This study guide will help you prepare for the assessment by focusing on the learning goals. It does not cover everything. Use your portfolio for help and ask if you need help. After, consider reviewing theentire portfolio too.

  1. Develop an understanding of ______group ______communication, and the benefits of working as a ______member.

Name 3 benefits to working as a team.

______

______

______

How have you contributed positively during class labs/activities? ______

  1. Compare/contrast science engineering, including the main ______of each.

Indicate Science (S), Engineering (E) or Both (B)

______a.Attempts to understanding phenomenon by asking questions about the world around us

______b.Attempts to solve problems to human needs

______c.Conducted through inquiry (observation and/or controlled experimentation)

______d.Emphasizes design &creativity

______e.Uses computational thinking

______f.Uses math

______g.Often has multiple solutions

______h.Biology, physics, chemistry, geology, botany, etc.

______i.Civil, aerospace, chemical, nuclear, software, biomedical, etc

  1. Provided a simple question or observation, design a ______experiment.

Watch Brainpop: Scientific Method

  1. Tim’s Main Question: ______

Recognize the problem & make observations

  1. Tim’s Hypothesis: ______

An “educated guess” to the main question, based on research & involves numbers

  1. Test the hypothesis through a Controlled Experiment

Tim’s Independent Variable: ______

  • Experimental/Changing, what “I” manipulate or change in the experiment

Tim’s Dependent Variable: ______

  • Measured, “depend” on the independent variable

Tim’s Control Group: ______

  • One group that does not receive the “independent” variable

Tim’s Controls: ______

  • Constants, everything else that remains unchanged during the experiment
  1. Analyze data

Do math, create graphs that visually answer the main questions

  1. Tim’s Conclusion:______

Use data to answer the main questions & readdress the hypothesis

Explain WHAT happened, and most importantly, WHY

  1. Make recommendations

Do you need to retest or not? What could be done differently?

Or, if everything went well, what could be tested further?

Tim knows how much water his plant requires, but he doesn’t know what type of soil (regular, potting soil, organic compost) will grow the best figs. In the space below, describe how Tim could test this new question. Be specific, state the variables & controls, be clear in how you would obtain data, and provide a concise description of the procedures.

  1. Conduct experiments & make accurate measurements using the ______system, with the understanding of its preference over ______units.

What are you measuring? / What measurement tool would a scientist use? / What unit(s) would a scientist use?
An object’s length
An object’s temperature
A liquid’s volume
A solid object’s volume
An object’s mass
An object’s weight

Make sure you know HOW to use the measurement tools listed above to find accurate measurements of various objects, as we did in the Notes: Metric System. Feel free to practice at the stations.

Convert150 cm = ______m0.90 dag = ______g8 L = ______daL

>, <, or =?520 cm ______52 dm480 mm ______0.5 m1.6 m ______16 cm

What are 2 advantages to using the metric system?

  1. ______
  2. ______
