Sizing Up Hail
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 measurements.
Bean BugsAdd to list Details
In this outdoor biology and math activity, learners estimate the size of a population of organisms too numerous to count.
Mega BounceAdd to list Details
In this outdoor activity (on page 2 of the PDF under GPS: Baseball Activity), learners will investigate the transfer of energy using sports equipment.
Counting With QuadrantsAdd to list Details
Millions of organisms can live in and around a body of water.
Super BounceAdd to list Details
In this activity (on page 1 of the PDF under SciGirls Activity: Soccer Ball Kick), learners will investigate the transfer of energy using sports equipment.
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 labels
Special Snack: Budgeting for HealthAdd to list Details
In this activity, learners will plan a snack within a budget. With a $20 limit (theoretical) to spend on snack for everyone, learners look over grocery store circulars and make their shopping lists.
Clam HoopingAdd to list Details
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.
Is It Possible: Estimating MeasurementAdd to list Details
In this activity, learners will decide together on a question about how far, long or high the group could reach together.
Mystery Jars: Estimate ContentsAdd to list Details
This activity puts a mathematical twist on the familiar “guessing jar.” No guesses allowed, estimates only.
Tree TallyAdd to list Details
In this outdoor activity and fun race, learners first find the most common type of tree in a forest site.
Make a Snake String & Snake Survey
In this activity, learners will construct a measuring device (snake "string") to improve their observation skills.
Mystery Jars: Make Your Own: Estimating and CountingAdd to list Details
Learners make a counting/estimating jar to exchange with friends or bring home.
In this "Sid the Science Kid" activity from Episode 103: Enough With the Seashells!, learners practice estimating numbers of objects (like shells) and then check their estimates by counting.
Counting Your Lucky Stars
In this activity, learners sample a star field to estimate the number of stars in the universe.
Fossil Age Estimation ModelAdd to list Details
In this activity (page 1 of the PDF under SciGirls Activity: Dinosaurs), learners will model how paleontologists estimate the age of fossil discoveries by extracting “fossil” playing cards from newspa
OBIS Oil SpillAdd to list Details
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.
Elephant FootAdd to list Details
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.
Piles of PenniesAdd to list Details
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.
Metric CapersAdd to list Details
In this outdoor activity, learners measure familiar objects in nature to practice working with the metric system.
