Measuring Your Breathing Frequency at Rest
Source Institutions
In this activity about the brain and sleep (on page 138 of the PDF), learners measure their resting breathing rates. Learners will discover that breathing frequencies vary amongst individuals.
Modeling Mendel's Pea Experiment
Source Institutions
This modeling activity allows learners to discover for themselves what Mendel uncovered in his famous pea experiments.
Modeling Limits to Cell Size
Source Institutions
This investigation provides learners with a hands-on activity that simulates the changing relationship of surface areas-to-volume for a growing cell.
Why Circulate?
Source Institutions
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
Now or Later: The "Recency/Primary" Effect
Source Institutions
In this activity (18th on the page), learners conduct an experiment to examine memory.
Aye-Aye
Source Institutions
This is an activity about the adaptations that allow the Aye-aye to survive in its habitat. Learners will explore how the Aye-aye collects food and how this is influenced by their specialized finger.
Counting With Quadrants
Source Institutions
Millions of organisms can live in and around a body of water.
Effect of Environment on Plant Growth
Source Institutions
The purpose of this plant biotechnology activity is to demonstrate the effect of changes in the environment on the growth and fertility of landscape grasses and crop grasses such as wheat and rice.
Workin' It Out
Source Institutions
In this activity, learners explore how to stay fit the fun way. Learners participate in three physical activities.
What Trickles Down?
Source Institutions
Learners design their own experiment to explore the permeability of different materials such as soil, sand, gravel, and marbles.
Get a Leg Up
Source Institutions
In this activity, learners experiment and collect data during a simulation of the fluid shifts experienced by astronauts' bodies in microgravity.
Altered Reality
Source Institutions
In this activity, learners discover that the human brain is highly adaptable. Learners try to toss beanbags at a target while wearing prism goggles.
Mapping Sea Level Rise
Source Institutions
In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.
Bones
Source Institutions
In this health activity (page 5 of the PDF), learners will explore a unique connection betweeen the bones of the body.
Neural Network Signals
Source Institutions
In this activity, learners create an electrical circuit and investigate how some dissolved substances conduct electricity.
Weighty Questions
Source Institutions
In this activity about humans and space travel (page 1 of PDF), learners compare and contrast the behavior of a water-filled plastic bag, both outside and inside of a container of water.
Visualizing How the Vestibular System Works
Source Institutions
In this activity (page 59 of the PDF), learners spin and observe false eyelashes in jars of water (prepared at least 1 day ahead of time) to investigate the effects of different types of motion on the
Muscle Fibers
Source Institutions
In this activity about human anatomy (page 20 of PDF), learners investigate the structure of muscles by comparing yarn and cooked meat.
This Bitter Be Good
Source Institutions
In this health and genetics activity, learners determine whether tasting the bitter compound PTC (phenylthiocarbamide) influences which vegetables a person likes.
Avogadro's Bubbly Adventure
Source Institutions
In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.
