What Color is Your Air Today?
Learners develop awareness and understanding of the daily air quality using the Air Quality Index (AQI) listed in the newspaper or online.

Diatom Ooze: Ooze Clues
Source Institutions
In this activity, learners will plot the distribution of various oozes using information from sediment maps.

Number Sense and Computation: Food For Thought
Source Institutions
In this math lesson, learners identify and compare unit costs of given items. Learners use computation skills, problem solving and number sense to find the cost of an ounce of cereal.

How Long Can You Hold Your Breath?
Source Institutions
In this activity (on page 142 of the PDF), learners will compare breathing rates before and after hyperventilation to explore how reduced carbon dioxide levels in the blood lower the need to breathe.

Classroom Dinosaur Dig
Source Institutions
In this activity, learners participate in a simulated dig to discover fossilized dinosaur bones. Learners take notes, make a map and propose theories about dinosaurs.

Geometry and Spatial Relations: Tessellations WOW!
Source Institutions
In this math lesson, learners explore tessellations through literature, music, writing, and art activities.

How Fast Can a Carrot Rot?
Source Institutions
Learners design their own experiment to determine conditions that either help or hinder the decomposition of carrots by soil microbes.

It's all Done with Mirrors
Source Institutions
This fun and simple hands-on astronomy activity illustrates the path of light as it reflects off of mirrors and how this is used in telescopes.

Conductivity: Salty Water
Source Institutions
Water, whether fresh or salty, serves as one of the best electrical conductors on the planet. Does salt effect its conductivity?

Invisible Sunblock
Source Institutions
This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.

Shapes and Colors and Textures, Oh My!
Source Institutions
This is an activity about discovering the colors and beauty of nature. Learners will spend time outdoors, matching paint chip samples, colored paper, or colors of clothing to those found in nature.

Why do Raindrops Sometimes Land Gently and Sometimes Land with a Splat?
Source Institutions
In this activity, learners examine raindrop bottles (prepared ahead of time) to observe in slow motion the behavior of falling droplets and explore concepts such as drag and terminal velocity.

Create a Pasta Population Map
Source Institutions
Learners work as a group to create a map of their community. They use pasta to represent people, and glue the pasta on their maps to show areas of large population.

Particle Detection
Source Institutions
By tossing, collecting, and sorting beanbags, learners understand how the IBEX spacecraft uses its sensors to detect and map the locations of particle types in the interstellar boundary.

Leaf it to Me
Source Institutions
In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

Gene Switches
Source Institutions
In this activity, learners explore how genetic switches function and the role of genetic switches in the process of evolution.

Not Just A Bag Of Beans
Source Institutions
In this activity, learners count and measure kidney beans to explore natural selection and variation. Learners measure the length of 50-100 beans.

Magnifying and Observing Cells
Source Institutions
In this activity related to microbes, learners make slides of cells from an onion skin and Elodea (American or Canadian waterweed) to observe under a microscope.

Shoebox Dinosaur Dig Site
Source Institutions
In this activity, (on page 6 of the PDF under SciGirls Activity: Dinosaurs) learners participate in a hands-on fossil excavation.
