Baroreceptor Reflex Role Play
Source Institutions
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.
Spider Glider
Source Institutions
In this fun activity about spiders, learners build and design a spider from cardstock, straw, string, and pipe cleaners.
DNA Detective
Source Institutions
This activity is about collecting and analyzing DNA as part of a criminal investigation.
Paint by the Numbers
Source Institutions
In this pencil and paper activity, learners work in pairs and simulate how astronomical spacecraft and computers create images of objects in space.
Jumpin' the Gap
Source Institutions
In this simulation of synapses, learners act out communication at the neural level by behaving as pre-synaptic vesicles, neurotransmitters, post-synaptic receptors, secondary messengers and re-uptake
Spill Spread
Source Institutions
In this simulation, learners explore how ocean currents spread all kinds of pollution—including oil spills, sewage, pesticides and factory waste—far beyond where the pollution originates.
Why is the Sky Blue?
Source Institutions
In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.
The Carbon Cycle and its Role in Climate Change: Activity 1
Source Institutions
In this activity (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials.
Getting There!: Navigation and Trajectory
Source Institutions
In this two-part activity, learners map a navigation plan to get from Earth to Mars and back. In activity one, learners represent the orbital paths of Earth through dance and dramatic movement.
Rock Bottoms
Source Institutions
Learners add acid rain (nitric acid) to two cups that represent lakes. One cup contains limestone gravel and the other contains granite gravel.
High Rise
Source Institutions
In this design challenge activity, learners build a tower that can support a tennis ball at least 18 inches off the ground while withstanding the wind from a fan.
Close, Closer, Closest
Source Institutions
In this activity, learners perform an experiment that models a chromatography-like process called electrophoresis, a process used to analyze DNA.
Shadow Play
Source Institutions
In this three part activity, learners explore and experiment with shadows to learn about the Sun's relative motion in the sky.
Ocean in a Bottle
Source Institutions
In this simulation activity, learners observe what can happen when ocean waves churn up water and oil from an oil spill.
Microarrays and Stem Cells
Source Institutions
In this activity, learners use microarray technology to determine which genes are turned on and off at various points in the differentiation of pluripotent stem cells on their way to becoming pancreat
Do Sweat It!
Source Institutions
In this activity, learners explore why humans sweat. Learners compare the effects of heat on a balloon filled with air and a balloon filled water.
Seeing Is Believing
Source Institutions
This activity is designed to accompany the PBS documentary about African-American chemist "Percy Julian: Forgotten Genius." Learners look through two cups with small holes in them to simulate what it'
Four of the States of Matter
Source Institutions
This kinesthetic science demonstration introduces learners to four states of matter: solid, liquid, gas, and plasma.
Water on the Move: Wind and Waves
Source Institutions
In this simple activity, learners explore ocean waves. To find out if water moves forward toward the shore, learners create waves in a simulated ocean (small aquarium tank of water).
We Have Capture!
Source Institutions
Using simple materials, learners will construct the end effector (grasping device) of a robotic arm and use the device to capture and pick up an object.
