Astronomy
AstroTides
- AstroTides is a lesson which describes
how students can use the Law of Universal Gravitation, F = G*M1*M2/d*d
to calculate the tidal force. After performing the calculation
students will learn that the gravitational force between the Earth and
the Sun is much larger than the gravitational force between the Earth
and the Moon. Students are then encouraged to calculate the gravitational
force differential between the center of the Moon and the near and far
sides of the Earth to explain why the moon plays a greater role in the
earth's ocean tides.
Reasons
for the Seasons
- In this activity students simulate
the sun - earth system using a globe and a bright light source.
Then with the aid of a light intensity probe the students measure the
light intensity at varying degrees of latitude. As the light probe
approaches the north or south pole of the globe the measured light intensity
decreases. This observation illustrates how the incident angle
of the sun's light affects temperatures on the earth's surface.
Student's can then better understand that it is the tilt of the earth's
axis which causes seasonal variation in our weather patterns.
- StellarEvolution
This activity allows students
to compare stars according to their characteristics. Students
will classify stars by using standard criteria.
Tides
This activity allows students to explain
the positions of the sun, moon and earth by using orbital and physical
characteristics. Applications of Newton's
law of gravity prove the forces of the tides caused by the moon and
are compared to the gravity of the sun.
Seasons
This activity uses data collected by
a temperature probe to explain the angle of the sun's rays on the earth
and the effect these changing angles have on our seasons.
Anatomy
and Physiology
Artery
and Vein Construction
- Students construct a model of an artery
and vein using household products.
Brain
Areas and Functions
- This activity allows the student to
design their own clay model of the brain.
Cardiac
Output and the Heart
- Students will construct a paper model
of the hearts anatomical parts and make a blood flow diagram.
- Do
Cows Eat Burritos?
- Cooperative anatomy and digestive processes
are demonstrated between ruminant and non-ruminant stomachs.
- Digestive
Travels of a Burrito
Understanding the sequence of events:
Where are which nutrients digested and what order of organs are involved
are demonstrated by the use of cut-outs.
How
Does Swallowing Effect the Burrito?
Esophageal peristalsis demonstrated
by a human wave and swallowing upside down.
- How
Many Burritos Does a Stomach Hold?
- Mechanical and chemical gastric action
in digestion is demonstrated through a chemical experiment.
Lymphatic
Trivia
- Students will make a body cutout game
board using the lymphatic system as a travel path.
Reaction
Time
- This activity allows the student to
design their own experiments to test and compare reaction times using
different stimuli.
Taste
- This activity allows students to test
and map the different taste regions of the tongue.
What
If That Burrito Was Bad?
How physical rejection and the body
deal with foods that may threaten health.
Where
Does a Burrito Go First?
Understanding the first digestive steps
involving mechanical and chemical digestion in the mouth.

Conserving
Fossil Fuels
- This lesson allows students to explore
steps that could be taken to reduce fossil fuel consumption.
Designing
Uses for Radioactive Isotopes
- Students apply their knowledge of half-life,
and types of radiation in selecting an appropriate radioisotope to solve
a problem.
Energy
Conversion
- This lesson gives students the opportunity
to calculate and compare fuel costs for different types of vehicles.
Science,
Technology and Society
Desirable
properties for Biodegradable materials - mechanical properties
- This lesson plan introduces students
who are learning about biodegradable packing materials/ technology to
the concept of packaging strength and durability. They investigate
the strength of various materials and then make and test various percents
of gelatin squares for durability and strength.
Comparing
Different Concrete Formulations
- Students will make different mixtures
of concrete using formulations given by the teacher. By sharing class
data, students will be able to see that by mixing different formulations
the concrete is used for different purposes. They will perform strength
and density tests.
Comparing
Different Kinds of Cement
- Students will mix up various combinations
of cement, water, salt, sugar and limestone to observe what happens
to the concrete as it hardens. Plaster of Paris and water will also
be used. Students will observe the time frame and the temperature changes
that take place while concrete is hardening.
Treasure
Hunt for Concrete Samples
- Groups of students will go on a treasure
hunt around the school grounds to find objects made of concrete. They
should discover that concrete can be made into many shapes and sizes,
and consist of large rocks and small pebbles. Afterwards, the class
will have a discussion and realize that concrete can be used for more
than sidewalks and roadways.
