Remind students that using these process skills as scientists do will lead to the development of their scientific knowledge.

5 How do Scientists Make Observations?
Scientists at Work – They… look closely at something use any of their five senses to collect information make qualitative observations use measurement tools to collect information make quantitative observations Explain/Evaluate: Ask How do Scientists Make Observations? Have students share ideas. Students can list and take notes in their notebooks.

6 How do Scientists Make Observations?
Scientists use their Five Senses Sight - Looks Touch - Feels Hearing – Sounds when moving… Odor – Smells Tastes SAFETY FIRST!! Never taste anything or put anything in your mouth without permission! What do we call these observations? Qualitative Observations Explore: Ask the question. Discuss and click on hyperlink for content video: Five Senses . Ask: What do we call these observations? Qualitative Observations

7 How do Scientists get precise or specific size information about objects?
Scientists use measurement tools to make observations that involve numbers or quantities. We call these quantitative observations. Explain: Ask question - How do Scientists get precise or specific size information about objects? After students respond click and show Scientists use measurement tools… Then ask what tools do scientists use to measure length… (ruler, tape measure, meter stick) Click for clip art. What else can these tools measure? (width, height, volume) What metric units are used? (meter, centimeter, millimeter) Continue in same format for mass, weight (Newtons, grams), volume (liters), temperature(Celsius, Fahrenheit and time. Explore/Explain/Evaluate: Pass out the lab sheet for Measurement Stations hands-on activity.

8 Making Observations Lab
Need: Scientists at Work: Making Observations Lab A small object Your senses and Measurement Tools Explore/Explain, Evaluate: Pass out the Making Observations Lab directions. Students complete the lab in their notebooks. See lab sheet for materials needed. Candy can be a tootsie roll, caramel, Now and Later, Star Burst, etc. After students complete the lab, they make reflections. Click on the hyperlink: Observing a Tootsie Roll See next slide.

9 Making Observations Lab
Reflection Questions Which of the senses was best for making observations about the candy? Explain your answer. Is the sense listed above always the best one to use? Why or why not? Give reasons to support what you think. Use evidence to explain why using tools to make observations is useful to scientists. Based on your observations, write at least three new questions you could ask about the candy. Explain/Evaluate: Have students share reflections focusing on the new questions.

10 Practicing Science: Observing the Natural World of Matter
What Is Matter? Matter is the material or “stuff” everything is made of. What are you doing if you are observing matter? Observing matter means to carefully explore all of its properties. Look around the room using your senses to identify some matter. What did you observe? What are some physical properties matter can have? Color, texture, odor, shape… What states of matter did you observe? Were you able to observe some solids, liquids and gases? Explore and Explain: Ask the questions as you move through the slide and discuss students’ responses. Also click on hyperlinks for content videos: Matter, properties, and states of matter .

11 What is a Solid? A solid has its own shape.
A solid does not change unless you cut, bend, or break it. Solids take up space and have mass. Teacher: Ask the question, what is a solid? Before showing the properties of a solid allow students to answer the question in their collaborative groups, as a think pair share. Then discuss and clarify misconceptions. Have students take notes in their science journals.

12 What is a Liquid? Liquids do not have their own shape.
Liquids take the shape of their container. Liquids take up space and have mass. Teacher: Ask the question, what is a liquid? Before showing the properties of a liquid allow students to answer the question in their collaborative groups, as a think pair share. Then discuss and clarify misconceptions. Have students take notes in their science journals.

13 What is a Gas? Gases have no definite size or shape.
Gases take the shape of its container. A gas will fill all the space inside a container. Gases take up space and have mass. Teacher: Ask the question, what is a gas? Before showing the properties of a gas allow students to answer the question in their collaborative groups, as a think pair share. Then discuss and clarify misconceptions. Have students take notes in their science journals.

14 Practicing Science: Observing the Natural World of Matter
What are two properties that all matter share? All matter has mass and takes up space or has volume. Explore and Explain: Ask the questions as you move through the slide and discuss students’ responses. Also click on hyperlinks for content videos: mass and takes up space.

15 What tools do scientists use to measure mass?
Balance & gram pieces Pan balance & gram pieces Triple Beam Balance Electronic balance Explain: Ask the question: What tools do scientists use to measure mass? Show students examples of any balances you have available and allow students to explore using small objects in the classroom.

16 Metric Units kg g What is mass?
Mass is the amount of matter in an object. The base unit of mass in the metric system in the gram and is represented by g. Metric Units 1 Kilogram (km) = 1000 Grams (g) 1 Gram (g) = 1000 Milligrams (mg) Click the image to watch a short video about mass. Explore and Explain: Have students measure the mass of a crayon and other small objects. . Find the mass of a crayon? What is it? About 5 grams Adapted from T. Trimpe

17 What is Length? Length- is the distance between two points.
How long is the screw in centimeters? It is 5.1 centimeters. Remember to measure to the smallest place value the tool allows and use decimals. What are the metric units for measuring length or distance? Units include the meter, centimeter and the millimeter. The basic unit of length in the metric system in the meter and is represented by a lowercase m. Explore/Explain: Ask the question: What is Length? What tools do scientists use to measure length? Show students tools to measure length you have available and allow students to explore using objects in the classroom.

18 1 centimeter = 10 millimeters
Measuring Length How many millimeters are in 1 centimeter? 1 centimeter = 10 millimeters What is the length of the blue line in centimeters? _______cm What is the length of the blue line in millimeters? _______mm HINT: Measure to the smallest place value the tool allows – use decimals. The line is 3.2 cm and 132 mm. Explore: Students explore the questions and measure a single marker and a crayon and compare. Crayola Marker 13.8 cm Crayon varies from amount of use: ≤ 9.1cm ≥ Measure the length of one marker. How long is it? Measure the length of a crayon?

19 What tools do scientists use to measure volume?
Measuring cups Graduated cylinders Beakers Measuring spoons Rulers or meter sticks or tape measures Explain: Show actual tools. Ask the question: What tools do scientists use to measure volume? Let students explore using measuring tools for volume (with water add food coloring for better view) and take notes in the science journals.

20 Click the image to watch a short video about volume.
kL Metric Units cL mL L What is volume? Volume is the amount of space an object takes up. The base unit of volume in the metric system in the liter and is represented by L or l. Metric Units 1 liter (L) = 1000 milliliters (mL) 1 milliliter (mL) = 1 cm3 (or cc) = 1 gram (with water) Explore: Demonstrate with a liter pitcher and liter measuring cups using colored water. Click the image to watch a short video about volume. *Which is larger? A. 1 liter or 1500 milliliters B. 200 milliliters or 1.2 liters Adapted from T. Trimpe

21 Measuring Volume Graduated cylinders are tools used to find the volume of liquids. Here’s how: Read the measurement based on the bottom of the meniscus or curve.* When using a real cylinder, make sure you are eye-level with the level of the water. What is the volume of water in the cylinder? 43 mL Explore and Explain Let students explore measuring water with food coloring added. *What causes the meniscus? The liquid in the graduated cylinder generally tends to stick to the sides of the cylinder. That is why for water and similar liquids we read the bottom. Adapted from T. Trimpe

22 Measuring Volume of Liquids
What is the volume of liquid in each cylinder? Explain/Evaluate: Ask students to find the volume of cylinders A, B, and C. C A B 22.5mL 52 mL 37 mL Adapted from T. Trimpe

23 Measuring Volume of Solids
What tool can be used to measure the volume of an object with the shape of a rectangular prism? We can measure using a ruler and the formula: length ___ x width ___ x height ___ = ______ cm3 10 cm 9 cm 8 cm What can be used to measure the volume of irregular shaped object (rock) ? water displacement using a graduated cylinder Explore and Explain Give each group a container of water and one small rock that will fit into the graduated cylinder available. Have them follow the steps to find its volume. Take notes on their science journals about their discovery. Amount of H2O with object = ______ About of H2O without object = ______ Difference = (rock) Volume = ______ Adapted from T. Trimpe

24 Temperature Degrees (°F)
Quantitative Temperature Degrees (°F) Fahrenheit is a unit used to measure temperature. Degrees (°C) Celsius is a unit used to measure temperature. Thermometer Teachers: Allow students to hold a thermometer in the their hand has you introduce the tool scientist use to measure temperature. Ask students to look carefully at the tool besides the numbers and ask: what else do you see on the thermometer? °C and °F yes, these are the units of measurement we use to measure temperature. Now look at the numbers under C=Celsius and now look at the numbers under F=Fahrenheit. What do you notice about those numbers? Students should notice that Celsius measures in smaller units, or numbers, while Fahrenheit measures in larger units or numbers. This is because Celsius belongs to the metric system which are small precise units which scientist use to measure. Fahrenheit measures belongs to the customary units of measurement.

25 Weight Ounces, pounds are units used to measure weight of an object.
Quantitative Ounces, pounds are units used to measure weight of an object. Personal Scale Explain: Ask the question: What tools do scientists use to measure weight? Show students examples of any scales you have available and allow students to explore using objects in the classroom. Spring Scale Single Pan Scale

26 Scientists Use Measurement Tools
Name of Tool Use of Tool (Quantitative Observation) Metric Units Ruler, tape measure, meter stick Explain/Evaluate: Students copy chart in their notebooks and keep a record of tools as they use them. (See slide for 4 for tool images.)

27 Scientists at Work: What do you see when you observe the apple?
Write in your notebook. Look over your list. Are they all observations? Remember, observations use the senses to gather information. Is there anything on the list that is what you think or infer? Engage: Show a model of an apple that looks real. Explore: Then ask them to write down their observations in their notebook. Explain and Evaluate: Have students share out their observations. Ask and discuss are the observations only observations or did they make any inferences and possibly an opinion. Why do think some of you were fooled? Why does being fooled by what you think is real affect what you think you observed?

28 Observations Compare and Contrast
Senses Inferences Observations Compare and Contrast Inferences Observation To observe is to look closely at something using any of the five senses and/or measurement tools. To infer is to use observations to reach a conclusion based on evidence. Opinion A personal belief that does not need proof. Explain: Compare and contrast observations, inferences and opinions. Students can give examples.

29 Observations Versus Inferences
Explore/Explain/Evaluate: Have students share observation lists after they’re finished. The class can check if anyone included inferences by mistake which will reinforce their observation skills. Next have students share their inferences and describe how the observations were used to support the inferences. Make Five Observations Make Five Inferences

30 Scientists at Work: Write one observation, one inference and one opinion about what you see in the photo. Explain/Evaluate: Have students write responses in their notebooks and share out their responses with the class. Remind students that making observations and inferences is commonplace in everyone’s life. In fact we make observations and inferences so readily that we seldom notice when we are doing so. In fifth grade we must learn to go beyond the casual observations of everyday life to move to more accurate and formal observations used in science. Review definitions of both (see slide 10) Evaluate: Ask students to describe an example of how scientists use observations and inferences to understand some aspect of the natural world.

31 Apply Concepts 1. Compare these two animals. List how they look similar and different. 2. Imagine you are on a camping trip. Upon waking up you notice a garbage can tipped over outside your cabin. Plastic bags are torn open. What could you infer? Explain and Evaluate

32 Scientists at Work: Classify Objects
Look at the shells in this photograph. What are some ways you could group them by their properties? Explore/Explain/Evaluate: First have students discuss with a partner, next within their group and last share out with the class.

33 Classify Objects 1. You and a partner get a set of objects.
2. Identify properties they share. 3. Organize them into categories by ways they are similar or related. 4. Share how your classification system with another pair of students. 5. Ask them to infer how you classified the objects. 6. Together, try other ways to classify the objects. 7. Discuss when each method could be useful. Explore: hands-on activity: Compare the objects and materials based on their physical properties including: Mass, shape, volume, color, hardness, texture, odor, taste, attraction to magnets.
