|Rubber Band Roller
We held a design
technology competition to see whose rubber band roller went the furthest
and whose was the fastest. Dave J's went the furthest (about 45 feet)
and Bill's was the fastest (around 2 ft/sec or about 1.5 mph).
Despite the rain we managed to
dip our nets between the bullrushes and even caught a large green frog.
Exploring the 5 Senses with
We explored the properties and characteristics of the five
senses through activities at different stations.
Using Microscopes to
We used microscopes to
increase the powers of our
visual observation skills.
Ramps and Cars
We rolled small "cars" down
ramps to explore the relationship between
slope, weight and distance. The goal was to make the "car" stop 4 feet
from the end of the slope.
The Egg Drop
made devices to protect eggs from being
broken when dropped from a great height. All,
except one, worked well when dropped from 9
feet. How will they fare when dropped from 95 feet?
Design Technology, Lego and basic programming
made model cars using Lego blocks and sensors.
We then programmed the models to perform simple tasks
using a computer programming system and radio control.
Motors and Magnets
We used the
STC Motors and
Magnets series of activities to
explore the properties and power
Tower and Pendulum
We discovered the difference
between design technology and science by
constructing a tower using a copy of the local newspaper
(design technology) and then
used the tower to explore the properties
of a pendulum (science).
Drops of Water
We explored the properties of water drops using the
science process skills.
We made drops of water using
dropper and then moved them around,
colored them, tried them on different
surfaces, made large and small drops,
and found how many drops will fit on
a penny. We discovered that a meniscus can be more than
a torn cartilage in
A day for exploring,
experiencing, and constructing meanings of constructivist
Putting the floor
blindfolded enabled us to examine
some of the assumptions we make
about learning, the power of prior
knowledge, and the need to establish
a common language so we could communicate effectively. As "observers", we
experienced how important wait time is and how hard it is not to jump in an
"tell" or "show".
