Lava Layering: Making and Mapping a Volcano
Source Institutions
In this activity, learners discover how geologists use stratigraphy, the study of layered rock, to understand the sequence of geological events.
Lean, Mean Information Machine: Using a Simple Model to Learn about Chromosomal DNA
Source Institutions
Learners observe a model of a cell and its chromosomal DNA made from a plastic egg and dental floss. Use this model to illustrate how much DNA is held in one cell.
The Missing Link
Source Institutions
In this activity, learners collect, analyze, and interpret information about objects in order to classify them into a cladogram. Use this activity to talk about how scientists classify things.
Lichen Looking
Source Institutions
In this outdoor activity, learners search for lichen, a combination of a fungus and an alga living together. Lichen grow where most other plants cannot, on rocks, the trunks of trees, logs and sand.
Engineering For Earthquakes
Source Institutions
In this design challenge, learners will engineer a structure and see if it can survive an earthquake they create.
Fan Cart
Source Institutions
If a sailboat is stranded because there is no wind, is it possible to set up a fan on deck and blow wind into the sail to make the boat move?
Our Sense of Sight: Color Vision
Source Institutions
In this activity, learners investigate color vision as well as plan and conduct their own experiments.
Two Washers
Source Institutions
In this activity, learners create a mind and math puzzle that requires a three-dimensional solution.
Matraca
Source Institutions
In this activity, learners create a traditional Mexican noisemaker (a matraca) using cardboard, craft sticks, and a wooden dowel.
Solar Structures
Source Institutions
In this activity, learners explore how the power of the sun can be harnessed to heat and cool a building.
Working with Wind Energy
Source Institutions
In this activity, learners explore how wind energy can be generated on both a large and small scale.
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.
Toxic Popcorn Design Challenge
Source Institutions
In this activity, learners explore the engineering design process (EDP)—the process engineers use to solve design challenges.
Engineered Music
Source Institutions
In this activity, learners explore how musical instruments are engineered.
Make Your Own Slushies
Source Institutions
In this activity, learners will make their own slushies and learn some of the science behind how the process works.
Build Your Own Robot Arm
Source Institutions
In this lesson, learners develop a robot arm using common materials. Learners explore design, construction, and teamwork, as well as materials selection and use.
How Quick Are Your Responses?
Source Institutions
In this activity (on page 134 of the PDF), learners explore reaction time.
Catapult
Source Institutions
In this activity, learners construct their own small catapults using simple materials. Learners follow visual instructions to build their launching device.
Clean Water: Is It Drinkable?
Source Institutions
In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.
Get It Write
Source Institutions
In this activity, learners explore how pens have been engineered and re-engineered over time. Learners work as a team to develop a working pen out of everyday items.
