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.
Lima Bean Bacteria DNA Extraction
Source Institutions
This laboratory exercise is designed to show learners how DNA can easily be extracted from lima bean bacteria. This experiment requires the use of a centrifuge (not included in cost of materials).
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
DNA Detective
Source Institutions
This activity is about collecting and analyzing DNA as part of a criminal investigation.
The Game of Life: Stem Cell Edition
Source Institutions
In this activity, learners play a game that models what happens as stem cells differentiate into different cell types.
Sound Dampeners
Source Institutions
In this activity, learners will experiment with water- and air-filled balloons as a way of dampening sound before it reaches their ears.
Amazon Water Cycle Roleplay
Source Institutions
In this creative roleplay activity, learners will explore the various processes of the water cycle using movement, sound, and props to aid in comprehension.
Gel Electrophoresis
Source Institutions
In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.
What is Light?
Source Institutions
In this four-part activity, learners will discover the exciting world of light--the most important form of energy in our world--and be able to identify and describe different types of light.
Why Are Bubbles So Colorful?
Source Institutions
In this activity, learners explore why they can see colors in bubbles and why they change.
Soap Film on a Can
Source Institutions
The beautiful iridescent colors of a bubble in a can! With this Exploratorium Science Snack, create beautiful soap films on the open end of a can to see beautiful rainbows of color.
Mirror, Mirror on the Wall: Angles of Reflection
Source Institutions
In this optics activity, learners work in pairs to explore how mirrors work. Learners use tape to mark the angles needed to see each other's reflection in a wall mirror.
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.
See It to Believe It: Visual Discrimination
Source Institutions
In this activity (12th on the page), learners investigate their ability to discriminate (see) different colors.
Dark Adaptation
Source Institutions
In this activity (6th on the page), learners investigate how photoreceptors in the eye (rods and cones) "adapt" to low light conditions.
Mystery Noises
Source Institutions
In this game (4th activity on the page) about hearing, learners test their ability to identify various sounds without looking.
Beam Me Up!
Source Institutions
This is a quick activity (on page 2 of the PDF under Stained Glass Activity) about the "Tyndall effect," the scattering of visible light when it hits very small dispersed particles.
How Loud is Too Loud
Source Institutions
In this activity (described on pages 39-42 of PDF), learners make a paper wheel (on pages 57-60 of PDF) that shows them the relative loudness of different sounds.
Clothespin Workout
Source Institutions
This is a great activity about human energy production. Learners will work out with a clothespin to investigate why hockey players jump on a stationary bike after an intense game.
Coral, Carbon Dioxide and Calcification
Source Institutions
In this group activity, learners act out key stages of the "ocean carbon cycle" (also known as the "carbonate buffer system") through motions, rearranging blocks and team tasks.
