• Lawrence Hall of Science
Using a real-size sketch of a baby elephant's footprint, learners estimate, measure and record the width (diameter) and outside edge length (perimeter or circumference) of the footprint. Then...

1 cent - \$1 per group Ages 4 - 11 30 to 45 minutes
• Lawrence Hall of Science
In this coin math activity, learners sort and stack 100 (one hundred) pennies into piles of 5 pennies each, 10 pennies each, and 20 pennies each. Learners count and measure the stacks and record...

1 cent - \$1 per group Ages 6 - 11 10 to 30 minutes
• NSBRI
In this nutrition and estimation activity (page 12 of PDF), learners estimate serving sizes of different foods and compare their estimates to serving size information provided on nutrition food...

\$5 - \$10 per group Ages 8 - 14 45 to 60 minutes
• Lawrence Hall of Science
In this outdoor activity and fun race, learners first find the most common type of tree in a forest site. Learners use a "transect," a kind of sampling technique, to estimate the number...

\$5 - \$10 per group Ages 8 - 14 45 to 60 minutes
• Lawrence Hall of Science
In this two-part outdoor activity, learners conduct a population census of squirting clams on a beach or mudflat, and investigate the clams' natural history. During the Clam Hooping activity,...

\$5 - \$10 per group Ages 8 - adult 1 to 2 hours
• Lawrence Hall of Science
In this outdoor biology and math activity, learners estimate the size of a population of organisms too numerous to count. In a process similar to that used by real field biologists, learners count...

\$10 - \$20 per group Ages 8 - 14 45 to 60 minutes
• Lawrence Hall of Science
In this outdoor activity, learners measure familiar objects in nature to practice working with the metric system. The goal is for learners to develop their "metric senses" by measuring...

\$10 - \$20 per group Ages 6 - 14 45 to 60 minutes
• Lawrence Hall of Science
In this outdoor activity, learners simulate an oil spill using popcorn (both oil and popcorn float on water), and estimate the spill's impact on the environment. Learners role play...

\$10 - \$20 per group Ages 8 - 14 45 to 60 minutes
• NASA
In this activity, learners sample a star field to estimate the number of stars in the universe. This activity simulates how astronomers use sampling instead of census (counting) to more easily...

free Ages 8 - 14 45 to 60 minutes
• NOAA
In this activity, learners will estimate the sizes of balls to learn how to estimate the size of hail. Learners will compare their estimates to the estimates of their peers and the real...
