1. Topic-
|
|
2. Content-
|
Investigating the heat mechanical and electrical machines produce
will demonstrate that heat is produced in motion |
|
|
3. Goals: Aims/Outcomes-
|
1. Observe simple objects and report observations.
2. Conduct a simple investigation when given directions.
3.Pose questions about objects, events, and processes. |
|
|
4. Objectives-
|
1. Students will observe machines and report in journal.
2. Students will be told to go around school and get temperature of
machines.
3. Student will answer questions about their predictions and findings. |
|
|
5. Materials and Aids-
|
Thermometer
Graph paper
pencil
magazines
scissors
glue
crayons
markers |
|
|
6. Procedures/Methods-
|
A. Introduction-
1. Lesson will begin with reviewing where heat comes from and how
it is produced.
2. Students will talk about ideas of what makes a machine hot? And
what machines would be hotter and not and why?
|
|
|
B. Development-
1.Students will walk around school finding mechanical and electrical
machines that they think produce heat when operating
2. When getting back in classroom students should draw in science
journal what machines they saw and divide them into mechanical and
electrical
3. Have the students decide on three machines from each category
4. Students should then predict the temperature of the machine
|
|
|
C. Practice-
1.Students will then go around and get temperatures of the machines
2.Class will have discussion on if their predictions were right and
discuss what machine had the coolest and hottest temperature and why?
3.Also talk about how long machines were running and if the machine
had a light too?
4. Together in small groups graph on a large piece of paper mechanical
and electrical that are found out of magazine. |
|
|
D. Independent Practice-
Students will then graph results
|
|
|
E. Accommodations (Differentiated Instruction)-
1.Student that would have trouble walking around school would be
with teacher
2. Students that have trouble working in group will work independently.
|
|
|
F. Checking for understanding-
Have student draw 2 mechanical and 2 electrical machines in their
science journal and check for accuracy. |
|
|
G. Closure-
Display charts in classroom and discuss as a class their findings
|
|
|
7. Evaluation-
|
Demonstrate that mechanical and electrical machines produce heat
and sometimes light.
