Stick to It: Adhesion II
Source Institutions
Water sticks to all kinds of things in nature — flowers, leaves, spider webs - and doesn't stick to others, such as a duck's back.
Resistance is Useful
Source Institutions
Learners write or draw with white crayon on white paper. They look and feel to detect their marks on the paper. Then, learners paint over their paper with watercolor paint.
Apples with Appeal
Source Institutions
In this activity, learners investigate why apples turn brown. Learners discover that lemon juice interferes with the reaction that causes the browning.
Seeds: Roots and Shoots
Source Institutions
In this indepth hands-on activity, learners build a structure that allows them to observe the growth of roots and the correlation between root growth and stem extension.
Changing the Density of an Object: Adding Material
Source Institutions
Learners see that a can of regular cola sinks while a can of diet cola floats. As a demonstration, bubble wrap is taped to the can of regular cola to make it float.
Butterflies in Space
Source Institutions
The Butterflies in Space Teacher's Guide uses "life in space" to encourage learners to conduct their own open-ended scientific investigations.
What's in a Penny?
Source Institutions
In this chemistry activity, learners use chemical reactions to observe the composition of an alloy.
Water Ways
Source Institutions
In this activity (on page 2 of the PDF), learners explore surface tension by adding pennies to cups which are "full" of plain water or soapy water.
Blowin' in the Wind
Source Institutions
In this weather activity, learners build their own wind detector and test for the presence of convection currents in their indoor location.
Milk Carton Boats
Source Institutions
This activity (on page 2 of the PDF SciGirls Activity: Milk Carton Boat) is a full inquiry investigation into boat hull design.
How Might Elevated CO2 Affect Plants
Source Institutions
In this activity, learners conduct an experiment to investigate the effect of elevated levels on CO2 on plant growth.
Balloon Impacts
Source Institutions
In this activity, learners measure the diameter of their water balloons, model an impact, measure the diameter of the “crater” area, and determine the ratio of impactor to crater.
The Old White Sheet Trick: Light and Insect Behavior
Source Institutions
In this outdoor, nighttime activity, learners gather around a brightly lit, white surface and study the behavior of nocturnal animals attracted to the light, particularly night fliers.
Push Me a Grape
Source Institutions
In this physics activity, learners experiment with the attractive and repulsive power of magnets.
Sand Dunes
Source Institutions
This outdoor activity (on page 2 of the PDF under SciGirls Activity: Sand Dunes) is a full inquiry investigation into how the amount of moisture in a sand dune relates to the number of plants growing
Off Base
Source Institutions
In this activity, learners explore the factors that tend to resist changes in pH of the ocean and why the ocean is becoming more acidic.
I Can't Take the Pressure!
Learners develop an understanding of air pressure in two different activities.
Delicious Smelling Chemistry
Source Institutions
In this activity, learners use household materials to investigate and explore their ability to smell an odor.
What's Hiding in the Air?: Rubber Band Air Test
Learners build devices from rubber bands to test for invisible air pollutants.
Biomimicry: Synthetic Gecko Tape Through Nanomolding
Source Institutions
In this activity/demo, learners examine a synthetic gecko tape with micron sized hairs that mimics the behavior of the gecko foot.
