HANDS-ON LAB SKILLS/SCIENCE INQUIRY Science Inquiry Scientists use the scientific method when they conduct experiments and investigations. Scientists may use all or only some of the steps in scientific method as they work. Steps to Using Scientific Method Step 1: Ask a question about something you observe. Step 2: State your hypothesis, which is a possible answer to your question. Step 3: Identify your control variable, which is the part of your experiment that is not and is used for comparison. Step 4: Test your hypothesis by conducting an experiment. Step 5: Collect and record your data during your experiment. Step 6: Interpret your data check your notes and observations. Step 7: State your conclusion, which explains whether or not your results support your hypothesis. Lesson Checkpoint: What is a hypothesis? Lab Safety There are many important rules to follow and guidelines to keep in mind when conducting an experiment or investigation. Some of those include: Listen to all directions before beginning. Always wear goggles to protect your eyes. Clean up all spills. Never taste anything unless your teacher tells you that it is okay to do so. Handle all equipment carefully, especially sharp or breakable tools. If something doesn’t look or smell right, tell your teacher right away. Wash your hands thoroughly when you are all finished. © Copyright NewPath Learning. All Rights Reserved.

Lesson Checkpoint: What should you always do when you have finished an experiment? Tools Used in the Lab There are many tools that can be used to study and measure objects. Some of those tools include: A balance is used to measure the weight of an object. A hand lens (also known as magnifying glasses) and a microscope can be used to enlarge an object so you can study objects in great detail. Thermometers are used to measure temperature. Metric rulers are used to measure the length and width of objects. A camera can be used to document how an object changed over time. Funnels can be used to pour liquids or substances into a small opening. Filter paper can be used to separate a solid from a liquid.

Making Predictions and Drawing Conclusions When you conduct an investigation, you may make predictions, interpret your findings, draw conclusions, and justify your conclusions. When you conduct an experiment, you should collect data to help justify your conclusions. Charts and graphs help you organize your data. You may interpret your charts and graphs to justify the predictions you have made during an investigation. Measuring and Estimating During an investigation you may need to find the actual measurements of objects or you may be able to estimate a measurement. Cause and Effect During an investigation, you may formulate and justify your predictions based on cause and effect relationships. Cause and effect is a relationship between two things. A cause makes something else happen. An effect is what happens because of the cause. Example: Cause: Plant A was over-watered every day. Effect: Plant A died.
