Curated OER
Estimating Altitude of Water Cloud Base
Students conduct an experiment to determine dew point and use a formula to detemine altitude. They construct a chart and predict what altitude clouds would form, given the dew point on the ground.
Curated OER
Does Contact Area Matter?
Learners work together to design and implement an experiment on friction. They test to see if contact area affects the amount of friction. They discover how engineers use friction to make certain products better.

Raquel's Radishes
Sixth graders develop a reasonable hypothesis for a fictional science fair investigation. 'Raquel' is going to grow radishes and test for the best way to nourish them. They create a bar graph and write conclusions.
Curated OER
Cloud Shadows
Learners classify clouds as transparent, translucent or opaque. They conduct an experiment to determine the visual opacity of several classroom objects and then conduct further observations of clouds.
Curated OER
Icebergs: Relationship of Ice to Water
Students experience why ice floats and the differences in weight of frozen water to liquid water. Students explore why ice floats. They use math skills such as: graphing, applying procedures, weighing and measuring. Students also use...
Curated OER
Downhill Discoveries
Students are involved in hands-on activities to determine how course conditions affect bobsled, luge, and downhill ski races.
Curated OER
Block & Tackle
Learners participate in a lab experiment in which they discover the need for so many blocks and tackles on sailing ships. In groups, they make and test their predictions and practice measuring objects in various units. They record and...
Curated OER
Scavenger Hunt
Students collect data about lighting conditions around a room using a light sensor and RCX. They use software to upload and analyze the data in order to draw conclusions about light intensity in the room.
Curated OER
Animal Fractions
In this fractions learning exercise, students find the height of each animal before the growth chart experiment. Students subtract the growth of week 1, week 2, and week 3 from the final height.
Curated OER
Measuring the Diameter of Our Star
Students conduct an experiment to measure the diameter of the sun. In this astronomy lesson, students construct a simple equipment to collect scientific data. They calculate the sun's diameter using a given formula.
Curated OER
Sliding and Stuttering
Students measure frictional force existing between a moving cup and the surface it slides on. They conduct the experiment and answer discussion questions.
Texas Instruments
Circle Equations
Students explore the coordinate plane. In this secondary mathematics instructional activity, students follow a set of directions to plot points in the coordinate plane.
Curated OER
Let Your Ears Do the Walking
Young scholars examine the effects of bycatching on water environments. They discover how echolocation works. They participate in a simulation of the process to use it while walking blindfolded.
Curated OER
Making Paper
Students make paper from recycled paper. The student estimates, counts, and measures he amount of paper consumed in a classroom daily. They discover that if we use too much paper, it fills up landfills. Some activities they are doing...
Curated OER
Teaching The Scientific Method Using Adhesives
Young scholars use the six step scientific method to experiment with the differences in adhesives. Students test for tack, shear, and peel in these activities.
Curated OER
WHAT HOLDS US TO EARTH?
Students they imagine they are Galileo and try to duplicate Galileo's experiments and results.
Curated OER
Estimating Large Numbers
Learners experience large numbers by estimating the number of grass blades in a field. They work in small groups to determine numbers of blades of grass in a small area of a field and apply that to determining the total number of blades...
Curated OER
Water Density Boundaries
Students create observable layers in water that represent a separation based upon density differences. They model density boundaries using differences in temperature and salinity. They, in groups, perform a meaningful experiment...
Curated OER
How Electronics Come to Us: Distribution and Use
Students identify environmental challenges that can be solved throughout a product's life cycle. They experiment and examine how we can choose and use products in an environmentally responsible manner. Each student is also involved in...

Clean Sweep
Students organize and conduct a cleanup of a local beach, lake, or stream. They keep track of the types and amounts picked up and analyze this information in the classroom.
Curated OER
WHY DO SOME THINGS FLOAT WHILE OTHERS SINK
Students explore how density can cause things to sink or float by experimenting with a jar, oil and corn syrup.
Curated OER
Nuts & Bolts: is Classification, Arbitrary, Or Not?
Students, in groups, classify furniture, share their categories and rationales, then note how their different schemes vary, perfectly logical and useful, but completely arbitrary.
Curated OER
May The Fastest Toy Win
Students determine which wind-up toy is the fastest. However, they can NOT race the toys. They must find another way. On the first day of the activity, students work in pairs or small groups to develop and write a plan.
