Matraca
Source Institutions
In this activity, learners create a traditional Mexican noisemaker (a matraca) using cardboard, craft sticks, and a wooden dowel.
Design a Microexpression Zoetrope
Source Institutions
In this engineering design challenge, learners animate a facial expression and make a machine (zoetrope) that plays the animation back.
Lever Cowboy
Source Institutions
In this activity, learners build a figure that moves and "comes to life" when they pull its string.
River Catcher
Source Institutions
In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.
Sniffing for a Billionth
Source Institutions
This is an activity (located on page 4 of the PDF under What's Nano? Activity) about size and scale.
How Does Water Climb a Tree?
Source Institutions
In this activity, learners conduct an experiment to explore how water flows up from a tree's roots to its leafy crown.
Fuel for Living Things
Source Institutions
In this activity, learners observe what happens when yeast cells are provided with a source of food (sugar). Red cabbage "juice" will serve as an indicator for the presence of carbon dioxide.
Leaves: Designing Leaf Arrangements on a Branch
Source Institutions
In this hands-on activity, learners investigate the functional design of leaves on a tree.
Is It Alive?
Source Institutions
What does it mean to be alive? Is a cactus alive? Is a seed alive? Is the air we breathe alive? What are the necessary characteristics?
Control a Bird’s Flight
Source Institutions
In this engineering design challenge, learners make a bird and then control its flight with attached strings.
Paper Chromatography with Leaves
Source Institutions
In this activity on page 5 of the PDF (Plants—The Green Machines), learners use chromatography to separate and identify pigments within various leaves.
Trash Talkin'
In this activity, learners collect, categorize, weigh and analyze classroom trash and discuss ways that engineers have helped to reduce solid waste.
Earth Atmosphere Composition
Source Institutions
In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.
Gravity and Muscles
Source Institutions
In this activity about center of gravity (page 23 of PDF), learners investigate how the body adjusts to the force of gravity to remain balanced.
Lungometer
Source Institutions
In this environmental health activity, learners investigate their own vital lung capacities.
Oil Spill Cleanup
This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.
Popsicle Bridge
Source Institutions
In this activity, learners explore how engineering has impacted the development of bridges over time, including innovative designs and the challenge of creating bridges that become landmarks for a cit
Recycling Rules: Understanding Recycling and a MRF
Source Institutions
In this activity, learners simulate the separation techniques that materials recovery facilities (MRFs) use and then design their own series of recycling techniques.
Round, Light and Hollow
Source Institutions
In this activity about bones (page 12 of PDF), learners investigate and compare the weight-bearing capacity of solid and hollow cylinders.
Born of Blood: Craft Stick Chromosomes
Source Institutions
In this activity, learners work in groups to match craft sticks that represent chromosomes. Learners must define critical attributes of their chromosomes as they look for matching chromosomes.
