Students make simple observations and identify relevant variables, such as frequency and diameter. They then discuss the relationship between variables. The task assesses students' abilities to make simple observations and make...
Curated OER
Threads
Learners group observed data, filtering from all their observations the similarities between burring threads. In the second part they make a comparison of a chosen attribute between the two threads.
Curated OER
Magnets
Learners investigate the magnetic attraction of different materials by observing a demonstration, and review the words "attraction" and "materials." Next they conduct exploration of a number of materials which have different properties...
Curated OER
Boyle's Law
Students work in small groups and use a hand-held vacuum pump with a balloon under the dome with some air. Another deflated balloon is attached to the end where the air goes out. As the air is drawn out of the dome the first balloon with...

What Are Ecosystems?
Third graders recognize and examine ecosystems. They observe and describe habitats within ecosystems and observe and identify organisms with similar needs that compete for resources.
Curated OER
Energy Conservation
Students complete a variety of activities as they examine forms of energy, use of energy, different technologies to harness energy and the ethical implications of these sources and technologies.
Curated OER
Observing Objects
Students observe the motion of both a pendulum and a spring pendulum . They then explain the differences and the similarities between the two types of motions.
Curated OER
Colored Drops
Students examine the properties of a liquid that contains water and food coloring and a liquid that contains water, food coloring and a liquid detergent. They interpret their data, describe properties, and make reasonable explanations...
Curated OER
Sundials: Keeping Time Like Native Americans
Learners explore the use of sundials. They observe the shadows cast by the sun and record the times at various points throughout the day. They create sundials and record the location of the shadows and the time of day. They view a...
