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.
In this outdoor biology and math activity, learners estimate the size of a population of organisms too numerous to count.
In this outdoor activity (on page 2 of the PDF under GPS: Baseball Activity), learners will investigate the transfer of energy using sports equipment.
Millions of organisms can live in and around a body of water.
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
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.
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.
In this activity, learners will decide together on a question about how far, long or high the group could reach together.
This activity puts a mathematical twist on the familiar “guessing jar.” No guesses allowed, estimates only.
In this outdoor activity and fun race, learners first find the most common type of tree in a forest site.
In this activity, learners will construct a measuring device (snake "string") to improve their observation skills.
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.
In this activity, learners sample a star field to estimate the number of stars in the universe.
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
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.
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.
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.
