Mapping the Classroom
Source Institutions
In this activity, learners discover the importance of maps and scale as they work together to create a map of the classroom.
Rate It: Working With Zero and Negative Numbers
Source Institutions
In this activity, learners will rate the day, a book, or something else on a scale from -2 to 2. This activity works well for groups of all ages.

Earth Walk
Source Institutions
In this hands-on and feet-on excursion, learners take a science walk to visualize the planet's immense size and numerous structures, without the usual scale and ratio dimensions found in most textbook

Make a Dinosaur
Source Institutions
In this activity, learners explore the size and scale of dinosaurs. Learners listen to "Dinosaurs, Dinosaurs" by Byron Barton to understand some background information about dinosaurs.

Probability: Chances Are
Source Institutions
In this math lesson, learners identify the likelihood of an event by using a walk-on probability scale.

Music and Sound
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Music and Sound) is a full inquiry investigation into sound frequency.

Size, Scale and Models
Source Institutions
In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.
Sea State: Forecast Conditions at Sea
Source Institutions
In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

Blazing the Trail
Source Institutions
In this math lesson, learners estimate distances between landmarks and use a map and scales to determine the actual distances.

Compare Dinosaur Body Parts
Source Institutions
In this activity, learners explore the size and scale of dinosaurs. Learners listen to "The Littlest Dinosaurs" by Bernard Most to learn about the different sizes of dinosaurs.

Incredible Shrinking Shapes
Source Institutions
In this activity, learners get hands-on experience with ratios and scaling while making their own jewelry out of recycled plastic containers.

Pennies for Pits
Source Institutions
In this math lesson, learners use fruit to learn about proportions and percentages. Learners compare the weights of the edible and non-edible portions of fruit.

Exploring Measurement
Source Institutions
In this "Sid the Science Kid" activity, learners use their bodies to measure a room. Instead of inches or feet, how many kids does it take to measure the length of a room?

The Search for Secret Agents
Learners tour their school or home looking for sources of indoor air pollutants (IAPs).

Shark Sizes
Source Institutions
In this graphing exercise (page 2 of the pdf), learners compare their own height to the length of various sharks.

Swing in Time
Learners build and investigate pendulums of different lengths. They discover that the longer the string of the pendulum, the longer the time it takes to swing.

Chew that Gum
Source Institutions
In this quick activity (page 1 of PDF under SciGirls Activity: Exercise and Memory), learners will investigate what happens to bubble gum when it is chewed for 5-10 minutes.

Small Snails, Enormous Elephants
Source Institutions
This activity (located on page 2 of PDF) introduces learners to the real size of animals using nonstandard measurement.

Atmosphere Composition Model
Source Institutions
In this activity, learners create a model using metric measuring tapes and atmosphere composition data.
