Crossing the Synaptic Gap
In this neuroscience activity, learners conduct a simulation to demonstrate how multiple incoming signals influence the action of neurons.
DNA ExtractionAdd to list Details
In this activity related to plant biotechnology, learners extract DNA from fruit to investigate how it looks and feels.
Let's Clone a Mouse, Mouse, Mouse...Add to list Details
Somatic Cell Nuclear Transfer (SCNT) is a cloning method that involves transferring a nucleus from a somatic cell of the individual to be cloned to an enucleated egg.
Animal & Plant Cell Slides
In this activity, learners make slides of onion cells and their own cheek cells. Use this lab to teach learners how to prepare microscope slides and use a microscope.
Modeling Limits to Cell SizeAdd to list Details
This investigation provides learners with a hands-on activity that simulates the changing relationship of surface areas-to-volume for a growing cell.
In this activity related to the human circulatory system (on page 10 of the PDF), learners observe the dispersion of a drop of food coloring in water, draw conclusions about the movement of dissolved
Enhanced Water Taste Test
Learners conduct a "blind" taste-test of several types of enhanced or fitness water drinking water that has commercially added substances like vitamins, sugars, or herbs.
Make a big canvas of iridescent color with pvc pipe! In this Exploratorium Science Snack, you'll need to cut and assemble some PVC pipe, but the pay-off, the soap-bubble canvas, is big.
Giant Chromosomes: Fruit Fly DNA and YouAdd to list Details
Many of the genetic sequences found in the fruit fly genome are similar to those found in humans.
Transformation of E. coli Using Green Fluorescent ProteinAdd to list Details
In this activity related to plant biotechnology, learners transform a strain of E. coli using green fluorescent protein from a bioluminescent jellies.
This activity is about collecting and analyzing DNA as part of a criminal investigation.
DNA the Easy WayAdd to list Details
This demonstration can be used to help learners visualize DNA by lysing (breaking open) bacterial cells on a slide and “stringing up” the DNA with a toothpick in less than one minute.
Collaboration via Slime MoldAdd to list Details
In this highly collaborative activity, learners design and complete a controlled experiment which attempts to answer a simple question about the slime mold Physarum.
This activity was designed for blind learners, but all types of learners can use it to investigate how, in a one-celled organism such as a bacterium, the division of cells increases the number of cell
Pathways with FriendsAdd to list Details
Directed by instructional cards, learners kinesthetically model cell communication by acting as components in a cell signaling pathway.
DNA Extraction from Cheek CellsAdd to list Details
DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique.
Traveling Nanoparticles ModelAdd to list Details
This is an activity (located on page 3 of the PDF under Nanosilver Activity) about diffusion of small molecules across cell membranes.
Moving Molecules!Add to list Details
In this activity about molecular diffusion (located on page 2 of the PDF under Nanosilver Activity), learners will make predictions and move molecules of iodine through a seemingly solid plastic sandw
Make a DNA Model
In this activity, learners make a 3-D model of DNA using paper and toothpicks. While constructing this model, learners will explore the composition and structure of DNA.
Is It Alive?
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?
