Worksheet Make a Thermometer A thermometer is an instrument that measures the temperature. Temperature is measured in a scale called Fahrenheit (by most people in the United States) and in Celsius or Centigrade (used by scientists and by people in many other countries). The point where water freezes is 32 degrees Fahrenheit (F for short) and 0 degrees Celsius (C). The point where water boils is 212 degrees F and 100 degrees C. If you want to know how to convert from F to C or from C to F Material : 1. 2. 3. 4. 5. 6.

Tap water Rubbing alcohol (do not drink this) Clear, narrow-necked plastic bottle (11-ounce water bottles work well) coloring Food Clear plastic drinking straw Modeling clay

Procedure:

1. Pour equal parts of tap water and rubbing alcohol into the bottle, filling about 1/8 to a 1/4 of the bottle. 2. Add a couple of drops of food coloring and mix. 3. Put the straw in the bottle, but don't let the straw touch the bottom (DO NOT DRINK THE MIXTURE). 4. Use the modeling clay to seal the neck of the bottle, so the straw stays in place 5. Now, hold your hands on the bottle and watch what happens to the mixture in the bottle

Worksheet Objectives •

Practice measuring the length and width of objects around the classroom.

•

Create two bar graphs, comparing length and width.

•

Discuss why bar graphs are useful in displaying data.

Materials •

Length

•

weather

• Paper and pencils • Common objects: desk, chair, notebooks, textbooks • Rulers and tape measures • Graph paper (optional) • Colored pencils (optional) Procedures Tell students that they will learn measuring and graphing skills. Divide the class into 5 groups. Tell students that each group will measure the length and width of the objects listed below; they will draw one bar graph showing their lengths and a second bar graph showing the widths. 1.

Objects to Measure: •

desk

•

book

•

notebook

•

chalkboard

•

tissue box

2. Give students time in class to work on the activity. Remind them to measure accurately and record the width and length of each object. This will help them organize the data and have it available when it is time to create the graphs. (Be sure to tell them whether they should measure in inches and feet or meters and centimeters.) 3. Next, show students how to draw a bar graph. You may distribute graph paper, or have students draw the graphs on unlined paper. For the first graph, label the horizontal axis "Object" and the vertical axis "Length." For the second graph label the horizontal axis "Object" and the vertical axis "Width." Students may use a different color for each object.

4. Students have questions about how to draw a graph, show "Weather," Segment 2, which explains how to make bar graphs and why they are useful. 5. After each group has measured the objects and drawn the graphs, bring the students together for a discussion. Did the groups get similar results? What kinds of variations were in the results? What caused the differences? 6. Conclude by discussing why bar graphs are used to display data. Do students think it is easier to compare data looking at a graph or looking at a chart? Help students understand that a bar graph is a quick way to show results and compare data.

Instructional Process 1. Model : Discussion Cooperative learning Direct Instruction Task Assignment 2. Approach : Contextual Teaching and Learning Introduction 1. Motivate by asking the students how to make of purification of the water 2. The teacher tells the students that they will learn about mixtures which have various compositions and can be separated into their pure components by physical techniques. For example, a substance that is soluble in water can be easily separated. The teacher discusses with students how to filter dirty water using a simple technique, and then to identify the method of separating the mixture. Make sure that students understand the methods of filtering, distillation, evaporation, and sublimation. 3. Then, the teacher asks students to work it out through experiments. 4. Motivate and remind students to do activity. Ask the students about the relationship between of the physics and chemistry changes 5. State the objective of the learning. Main Activity Part 1. In this activity • Students are asked to take a spatula-full of powdered iron and put it on a piece of paper, and using the same size of spatula, to take copper(II) sulphate and to put it beside the iron. • The teacher reminds students that in each case, the iron and the copper(II) sulphate should be powdered, and to notice that the colors of the two substances are different.

•

The teacher asks students to mix the two substances and then asks: "Can you recognize the iron and the copper(II) sulphate?"

Part 2. In this activity: • Students are asked to put about 100 ml of water into a beaker glass, and to put the mixture of iron and copper(II) sulphate into the beaker. Then, the teacher asks them to stir the mixture for a few minutes using a glass rod. • The teacher asks students to observe accurately and see whether they can recognize the iron and the copper(ll) sulphate in solid phases. Part 3. In this activity: • Students are asks to prepare a filter paper and to put it in a funnel which is held in a stand. Then, the mixture is filtered through the paper in the funnel. The teacher reminds the students to be careful, so that they do not pour the mixture through the gap between the paper and the glass. • Students are asked to observe what happens when they pour the mixture. • The teacher asks students to look at the solid left on the filter paper, and tell them that the matter is called residue. • Students are asked whether they can guess what substance the residue is, and then, the teacher asks them to compare the color of the residue with those of iron and copper(II) sulphate. • The teacher facilitates the students to discuss about the blue liquid passing through the filter paper. • The teacher asks the students to think about what the blue liquid is. The expected answer is a solution. Then, the teacher asks them again what solution it is. The expected answer is that the liquid is a copper(ll) sulphate solution. Part 4. In this activity: • The teacher asks students to heat gently the solution they got from the filtering procedure, until the liquid becomes darker (saturated). • The teacher tells the students to allow the solution to settle for a few minutes and then ask them to observe the solution accurately. • Students are asked whether they find a blue crystal in the solution, and lets them discuss the crystal among themselves. • Students are asked to think about the whole process of separation they did. • The teacher asks the students to make a summary of all the processes and the results, and lets the students write their summary of the experiment from parts I to 4 in a systematic. Activity 5 Discussion: Separation of Mixture • The teacher facilitates a discussion on the separation of mixture on the basis of particle size and boiling point. • The teacher continues the discussion on the methods of filtering, distillation, evaporation, and sublimation.
