Background:
Students need a basic background in lab procedures, the scientific
method, and cooperative team work.
(timekeeper, supplies, clean-up).
Time: (Total 3-4 45 minute class sessions)
Activity Lab Worksheet Criteria using "scientific method" approach:
Title of lab Problem/Question
Hypothesis/Prediction(s)
Procedure:
Materials List
Diagram (of lab set-up) *optional
Step-by-step Process
Observations/Discovery Task(s)
Results (graphs, charts, tables...)
Conclusion
Research material *optional
Bibliography
*optional
Skills:
Interpreting data, making inferences, making predictions, graphing,
math problem solving,
diagramming, timing an action, observation, sequencing
Communication of ideas: verbal and writing format
Computer literacy
Cooperative learning
Effective use of Internet resources
Assessment:
On the activity labs, a rubric can be used. Factors for consideration
are: labs reports are complete, the
scientific method is used, data is well organized, work is neat,
and accurate grammar and spelling is used
Student assessment and/or degree of engaged involvement may be used
on other "discovery tasks."
Enrichment:
ACTIVITY #1
Although we don't really notice it much, air is all around us and is
pressing on everything all the time. Air pressure is caused because
air has weight and it is pulled
down to Earth by gravity. As it is pulled down it squeezes against
things - creating AIR PRESSURE. Slight changes
in air pressure give us a clue about weather changes. We can measure
air pressure and predict the weather with an instrument called a
BAROMETER.
WEATHER FORECASTING - MAKING A BAROMETER
MATERIALS
| 1-new balloon |
1-clean glass jar |
1-drinking straw |
| 1-toothpick |
1-rubberband |
1- 9x18 piece of cardboard |
| a piece of paper |
|
|
PROCEDURES:
(1) Cut the neck off the balloon. Stretch the balloon over
the jar and hold it in place with the rubber band.
(2) Tape the toothpick to the end of the straw. Tape the
other end of the straw to the center of the balloon lid. Make a weather
picture
chart on the piece of paper, with "good weather "marked at the top.
(3) Make a 1/3 section fold on the piece of cardboard (and cut
a triangle to form a support on the back), set the glass jar on the cardboard,
position the weather picture chart centered directly across from
the end of the toothpick and watch to see if the pointer moves a little
each day.
DISCOVERY TASKS:
(1) Check the movement of the barometer with that day's weather
and determine if there is "greater or less" air pressure on a sunny
weather day versus an overcast or rainy day. DISCOVERY
= Sunny days require _________ air pressure. (greater/less)
EXPLAIN in your science journal how your activity proves your "discovery
"statement.
(2) Now go ahead and collect air pressure data for a week (or
month) and make a line graph with your results.
ACTIVITY #2
WARM AND COLD AIR COLLISIONS
MATERIALS: 2-quart (sized)
glass jars, 1-pan of hot water, hemp rope (or incense),
ice cubes (enough to fit on bottom of one glass jar) 1-flashlight, 1-match.
PROCEDURES:
(1) Put one jar upright in the pan of hot water.
(2) Have your teacher put smoke in the two jars.
(3) Then stand the second jar upside down on the first bottle
with the mouths of the jar together.
(4) Put several ice cubes on top of the upper jar.
(5) Darken the room.
DISCOVERY TASKS:
(1) Use the flashlight and observe the movement of the smoke.
DISCOVERY = The air in the bottom
jar being heated will ____. When it near the top of the second bottle,
it will cool and begin to ___________________.
Air currents will ___________________ in the two jars. (cool/rise/swirl)
