In this activity, learners play a simple card game to learn the sequence of events in the transmission of nervous system signals.

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.

In this neuroscience activity, learners conduct a simulation to demonstrate how multiple incoming signals influence the action of neurons.

In this activity about the baroreceptor reflex (BR) arc (page 123 of the PDF), learners discover the importance of maintaining adequate arterial blood pressure through a role playing exercise.

In this activity related to plant biotechnology, learners extract DNA from fruit to investigate how it looks and feels.

This activity demonstrates the specificity of viral vectors for target cells in gene therapy delivery methods using two approaches: 1) STYROFOAM® models demonstrate viral ligand binding to receptor pr

In this biology activity (page 5 of the PDF), learners use yarn and sticky labels to build a model of a DNA strand. They discover that DNA is very long, very skinny, and packs well into cells.

In this activity, learners extract DNA from wheat germ. Use this activity to introduce learners to DNA, biotechnology and genetic engineering.

Using toothpicks, straws, or tubes of rolled up newspaper, learners create 3-dimensional models to illustrate the basic structure and function of the cell membrane, and place an object inside to repre

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.

In this activity, learners investigate color vision as well as plan and conduct their own experiments.

In this experiment with planaria (a type of flatworm), learners will investigate the capability of different body sections to regenerate.

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.

In this activity, learners play a simple card game to learn the sequence of events in the transmission of nervous system signals.

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

In this genetics activity, learners extract DNA from an onion, using detergent solution, a food processor, and rubbing alcohol. They will also discuss genetic engineering of plants.

In this outdoor activity, learners review the parts of the synapse and their functions by playing a game.

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.

Role-playing the parts of chromosomes and centrioles, learners use large chromosome models and nylon cords (spindle fibers and cell membranes) to walk through the processes of mitosis and meiosis.
