Overview

Skills and Processes is all about an understanding of what scientists do as they go about solving problems. Scientists often use a scientific method which is just an organized way of thinking and learning about the world around them.

In this unit we will be learning about scientific inquiry and some of the tools and methods used by scientists. Students should come to realize that science is something that is used by everyone!

Measurement Choice Work
Choice work is when you get the opportunity to make decisions about how you are going to learn.
Here are the guidelines:
  1. choose any combination of activities
  2. Your goal is to complete at least three of the choices
  3. be as creative as you like within the guidelines listed below
  4. turn in activities at any time during the working time period

Quick Steps for Metric Conversion
  1. Rewrite the problem
  2. Ask - Does the decimal move left or right?
  3. Count your jumps.
  4. Add your zeroes (placeholders) (if needed)
  5. Move the decimal.
  6. Rewrite the answer.





Liquid Volume Lab (aka - Rainbow Lab)
Purpose:
To develop the skill of measuring liquid volume using a graduated cylinder and metric units

Measurement
When we measure in Science we will always use the Metric System.

The following slideshow is an overview of the Metric System.

Click start and then follow the directions to complete the task. Make sure you read the directions!!!
After you have successfully completed the task, close the window and take the Self Test.








Metric Conversion and Types of Data Quiz

Click here to take a quiz about converting metric measurements and the difference between qualitative and quantitative data.







Grab It - Reflexes Experiment
Question - To what extent is there a difference between the reflexes of girls and boys?

Hypothesis - (in the form of an “I think ___ because _ .” statement)

Materials:
  • meter stick
  • girl and boy
  • data table

Procedures
  1. Read ALL procedures.
    Copy the data table (found below) to collect your data.
  2. Have the boy and girl hold out their dominant hand as you hold a meter stick up with the lowest numbers closest to the bottom. (use metric)
  3. Your partner should hold their hand out at waist height with the thumb and fingers making the shape of a letter U.
  4. Perform the experiment by dropping the meter stick for your partner and noting where they catch it. Record data. Perform this three times.
  5. Boys should test girls and girls should test boys.
  6. Submit your results here. Submit only the average number for each group member.
  7. Click here to answer some questions about the experiment.

Questions to consider:
  1. What was the one thing that you changed each time you performed the experiment? This is called the independent variable.
  2. What changed each time you performed the experiment? This is called the dependent variable.
  3. What were some of the things that you kept the same each time you performed the experiment? These are called the controlled variables.
  4. How could we make this experiment more accurate?

Global Precipitation Measurement

Globe Toss Activity
Materials:
  • Inflatable beach ball globe
  • Chalk/dry erase board, overhead or large paper and appropriate writing utensil
  • Open space in a room for students to form a circle

Procedures:
  1. Form a circle, leaving a little space between each person.
  2. Toss the beach ball globe around the room and catch it with both hands. It is important that you do not move your hands once you have caught the ball.
  3. Look to see what surface on the globe is under your right thumb, land or water? Use a chart to tally the results as you toss the globe. You can label two sides of a vertical line: landwater
  4. Toss the globe around the room at least 10 times. When you are done, find the average of each side. This will give you the percentage of land and water.
  5. You will find (unless you have a very unusual sample) that about 70% of the tosses result in a water location.

Egg Lab

Have you ever observed something and then had a question about why it happened? Perhaps you even had a guess as to why something happened. Once you start asking questions and making predictions, SCIENCE is happening!
In the Egg Lab, students will make observations of a hard boiled egg when they place it in two different liquids. You will start by making a prediction and then making observations. Finally you will begin to develop a plan for testing that prediction.

Key words
Definitions, facts, examples
Scientific Inquiry
  • Different ways that scientists study the natural world
  • Propose explanations
  • Based on evidence
Observing
  • Using your senses to gather data or information
Inferring
  • To come to a conclusion based on evidence
Hypothesis
  • A possible explanation or answer to questions
  • Educated guess
  • Must be testable
    • ask - Can you conduct an experiment?
Variables
  • Factors that can change in an experiment
Independent variable
  • The one thing that is changed by you on purpose
  • What is being compared?
Dependent variable
  • The factor that may change in the experiment
    • What happened in the experiment?
    • What was counted or measured?
Controlled Variables
  • controlled variables are things in the experiment that are kept the same
Controlled experiment
  • Experiment when only one variable is changed
  • Steps are taken to keep everything else the same throughout the experiment
Collecting data
  • Tables can be used to collect data
  • Graphs can help organize data to be analyzed
Two types of Data
  • Qualitative - data collected using words to describe something
    • examples - brown, white, big, tall, fast, slow
  • Quantitative - data collected using numbers to describe something
    • examples - 20 ml, 30 km, 18 vultures
Conclusions
  • A summary of what you learned from the experiment
Communicating
  • Sharing ideas and findings
  • Collaboration
Scientific theory
  • Well tested explanation for a wide range of observations or experimental results
    • Ex. Big Bang Theory
Scientific law
  • Statement of what scientists expect to happen every time
    • Ex. Gravity
