What are the steps of the Scientific Method?
Ask a question -- What do you want to learn
State your Hypothesis -- think of a statement about what you want to test to answer your question
Identify and Control Variables -- make sure you are testing only one variable at a time
Test your hypothesis -- conduct your experiments
Collect and Record Data -- write down all the information
Interpret your data -- read over and discuss what your data means
State your Conclusion -- determine if your data supports your hypothesis
Go Further -- Change your hypothesis, modify your experiments, and share your data

What phrase helps you to remember the scientific skills?
- Making and Using Models
- Making operational Definitions
- Estimation and measurement
What is the definition of observation?
Observation- to look at characteristics
What does it mean to classify something?
Classify- to put into groups based on characteristics and or behaviors.
What is the definition of estimation and measurement?
Estimation and measurement- Using different units like area, mass, temperature.
What is the process skill for infer?
Infer- Educated or reasonable guess about what is happening right now.
What is the science process skill for predict?
Predict- educated guess about what will happen in the future. ( weather forecast, support outcomes)
What are making and using models as a scientific skill?
Make a map or a drawing to help you plan in building. Easier to work with.
What is making operational definitions as a scientific skill?
Define an idea based on what you know, may change over time.
What are the tools for that help us see and hear better?
What are the tools of measurement?
- Stop Watch
- Metric Ruler
- Graduated Cylinder
- Spring Meter
What are the electric tools?
- Computer-Aided Models
What is the tool we'll use to find information of an area you are researching?
What is a hand lens and how do we use it in science?
A hand lens is a magnifying glass, a portable tool for examinating things. It makes things look larger, but not as much as a microscope does.
What is a microscope?
A microscope uses a series of lenses that make objects appear larger. You can adjust the position of the lenses to change the amount you magnify the object.
What is a stop watch?
A stopwatch is a watch with a hand that can be stopped or started. It is used for timing experiments.
What is a metric ruler?
A metric ruler or meterstick is used to measure length. A meterstick is one meter long. The stick is divided into centimeters and millimeters.
What is a graduated cylinders?
Graduated cylinders and beakers can be used to measure volume, or the amount of space an object takes up.
What is a camera?
Cameras can be used to take pictures of objects. Pictures help you record and compare objects and observe changes.
What is a thermometer?
A thermometer is used to measure the temperature of an object. The liquid (mercury) in the thermometer expands when both get warmer and contracts when both cool. This causes the liquid to move up and down the temperature scale. In the Celsius scale, 0° represents the freezing point of water, and 100° represents the boiling point of water.
What is a balance?
A balance is used to measure mass. To find the mass of an object, add standard masses to the pan opposite the pan holding the object. When the two pans are at the same level, the sum of the standard masses equals the mass of the object.
What are computers?
Computers are information and graphic machines. Scientists use computers in many ways, such as for collecting, recording, and analyzing data.
What is computer-aided design?
Computer-aided design is a way of using a computer to make plans such as drawings for a new machine or building.
What is a barometer?
A barometer measures air pressure, which scientists use to predict weather patterns.
What is a recording device?
Recording devices are used by scientists to record and learn about sounds made by organisms or objects.
What is a field guide?
Field guides are information books that provide helpful details while researching plants, animals, or stars in the field.
What is a calculator?
Calculators make analyzing data easier and faster.
What is a spring scale?
A spring scale is used to measure force in grams. Because the weight of an object is a measure of the force of gravity on the object, you can use a spring scale to measure weight.
What are binoculars?
Binoculars have two eyepieces that contain lenses that magnify objects. Binoculars allow you to see the details of objects like birds from far away.
What is a probe?
A probe is an instrument used for
investigating hard-to-reach objects or parts of objects.
A temperature probe is a sticklike tool inserted into an object to measure temperature. A space probe explores planets and other objects in space that people cannot reach.
What is a anemometer?
An anemometer measures wind speed and direction.
What is a voltmeter?
A voltmeter measures electric charge in a circuit. They are used to measure differences in charge between two points on a circuit.
What are the safety rules related to communication in science class?
Read the activity carefully before you start.
Listen to the teacher's instructions. Ask questions about things you do not understand.
Report an accident or anything you think is unsafe to the teacher immediately.
What are the safety rules related to materials?
Safety rules for materials:
- Wear goggles when instructed
- Use chemicals carefully.
- Handle sharp objects and other equipment carefully.
- Help keep plants and animals safe.
- Put tools and equipment away when you're done.
What are the safety rules related to habits?
Safety rules related to habits:
- Keep your area clean. Wipe up spills immediately.
- Never taste or smell chemicals that we are working with.
- Dispose of chemicals properly.
- Wash your hands when you are done.
