Number Patterns
Source Institutions
In this lesson, learners are challenged to discover the relationship among six numbers.
Dinosaur Breath
Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.
Catch a Wave: How Waves are Formed
Source Institutions
In this three-part activity, learners explore how waves are formed and why some waves are bigger than others. First, learners observe waves of water in a pan generated by an electric fan.
Nano Waterproofing
Source Institutions
This lesson focuses on how nanotechnology has impacted the design and engineering of many everyday items from paint to fabrics.
Elephant Foot
Source Institutions
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.
Safe Food Preparation
Source Institutions
In this activity about food safety and nutrition, learners investigate safe food preparation by making fruit ice cream.
What Color is Your Air Today?
Learners develop awareness and understanding of the daily air quality using the Air Quality Index (AQI) listed in the newspaper or online.
Food Webs
Source Institutions
In this activity, learners construct possible food webs for six different ecosystems as they learn about the roles of different kinds of living organisms.
Diatom Ooze: Ooze Clues
Source Institutions
In this activity, learners will plot the distribution of various oozes using information from sediment maps.
Piles of Pennies
Source Institutions
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.
Law of Conservation of Mass
Source Institutions
In this chemistry activity, learners explore whether matter is created or destroyed during a chemical reaction. They will compare the weight of various solutions before and after they are mixed.
Cold Metal
Source Institutions
In this activity, learners discover that our hands are not reliable thermometers.
How Long Can You Hold Your Breath?
Source Institutions
In this activity (on page 142 of the PDF), learners will compare breathing rates before and after hyperventilation to explore how reduced carbon dioxide levels in the blood lower the need to breathe.
¡Ventanas de Burbujas!
Source Institutions
En esta actividad sobre la exploración e investigación, los aprendices harán ventanas de burbujas.
Slide Projector Activities
Source Institutions
This resource contains several mini-explorations using a slide projector as a light source to investigate light and the properties of images.
Of Cabbages and Kings
Source Institutions
This lesson gives full instructions for making cabbage juice indicator, a procedure sheet for learners to record observations as they use the indicator to test materials, and extension activities to d
Classroom Dinosaur Dig
Source Institutions
In this activity, learners participate in a simulated dig to discover fossilized dinosaur bones. Learners take notes, make a map and propose theories about dinosaurs.
Using a Simple Astrolabe
Source Institutions
In this activity, learners use an astrolabe to measure the altitude of objects. Learners will first practice taking measurements by measuring the altitude of trees and buildings.
How Fast Can a Carrot Rot?
Source Institutions
Learners design their own experiment to determine conditions that either help or hinder the decomposition of carrots by soil microbes.
Convenient Carrier
Source Institutions
In this design challenge activity, learners invent a convenient way for someone using crutches or a wheelchair to carry small personal items.
