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. Tap water
2. Rubbing alcohol (do not drink this)
3. Clear, narrow-necked plastic bottle (11-ounce water bottles work well)
4. coloring Food
5. Clear plastic drinking straw
6. 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

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.
1. 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.
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.

• 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.
• 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.
• 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.
