Five-Layer Density Column
Source Institutions
In this activity, learners can create five-layer density columns by employing one of three (or all) methods.
Workin' It Out
Source Institutions
In this activity, learners explore how to stay fit the fun way. Learners participate in three physical activities.
Mix and Match
Source Institutions
In this optics activity, learners explore color by examining color dots through colored water and the light of a flashlight.
Beginning Statistical Inquiries into the Scientific Method: Jelly-Side-Down
Source Institutions
This activity allows learners to explore the scientific method in an open-ended fashion, using the 4-P Approach to Science Inquiry developed by the University of Wisconsin, Beloit.
Natural Selection in Protected and Unprotected Populations
Source Institutions
In this simulation, learners model two elephant seal populations and how they change over time. Learners start with cards representing a variety of seals.
How Big is Small
Source Institutions
In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.
Transformation of E. coli Using Green Fluorescent Protein
Source Institutions
In this activity related to plant biotechnology, learners transform a strain of E. coli using green fluorescent protein from a bioluminescent jellies.
Living Bones, Strong Bones
Source Institutions
In this activity about engineering, nutrition, and physical activity, learners design and build a healthy bone model of a space explorer which is strong enough to withstand increasing amounts of weigh
Insulation Station
Source Institutions
In this physical sciences activity, learners explore insulation. Leaners investigate how insulation can be used to slow down the conduction of heat from one side of a wall to the other.
Scaling an Atom
Source Institutions
In this activity, learners make a scale model of an atom to see how big or how small an atom is compared to its nucleus. Learners will realize that most of matter is just empty space!
Handwashing Laboratory Activities: Bowl Technique
Source Institutions
In this lab (Activity #2 on page), learners compare bacteria growth on two petri dishes containing nutrient agar. Learners touch the doors, faucets, etc.
A Swell Activity with Beans
Source Institutions
In this combination chemistry and physics activity, learners explore water absorption in dried beans or peas and learn how this affects their physical properties.
Bloomin' Bud Glyph
Source Institutions
In this math lesson, learners practice reading charts and graphs by creating and interpreting glyphs.
Eatem Up
Source Institutions
In this math activity, learners use gingerbread cookies to collect and organize simple data. First, learners read "The Gingerbread Boy" by Paul Galdone.
Salts & Solubility
Source Institutions
In this online interactive simulation, learners will add different salts to water and then watch the salts dissolve and achieve a dynamic equilibrium with solid precipitate.
Playing with Parachutes
Source Institutions
In this activity, learners explore how parachutes are used to slow down moving objects. Learners work in teams of "engineers" to design and build their own parachutes out of everyday items.
Does Sunscreen Protect My DNA?
Source Institutions
In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.
Rock Pioneers
Source Institutions
In this outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.
Measuring Your Blind Spot
Source Institutions
In this activity, learners calculate the width (horizontal diameter) of the blind spot on their retina. Learners make a blind spot tester using a piece of notebook paper.
Dr. Vet: Noses, Ears, Legs and Eyes
Source Institutions
In this activity, learners practice counting and multiplication as they figure out how many animal body parts they have to examine as "Dr. Vet."
