Mountains in the Sea
Source Institutions
In this 6-7 day investigation, learners begin with an introduction to seamounts that are present in the Gulf of Alaska.

Properties of Dust
Source Institutions
In this activity, learners carry out a scientific investigation of dust in their classroom. Learners produce an analysis on graph paper of the dust they collect over the course of a few days.

Reason for the Seasons
Source Institutions
In this activity (on page 6 of the PDF), learners plot the path of the sun's apparent movement across the sky on two days, with the second day occurring two or three months after the first.

Plant Piping
Source Institutions
Learners build models to learn about the special cells and structures that plants use to move water from their roots up through the stems and leaves.

Create a Food Diary
Source Institutions
In this nutrition activity (page 3 of the PDF), learners will record their food consumption for one day, and then evaluate how their actual diet matched up with the recommended diet.

Using a Sundial
Source Institutions
In this activity (on page 12 of the PDF), learners make a sundial (shadow clock) appropriate for their geographic location in the northern hemisphere and use it to tell time.

Microbes are Everywhere
Source Institutions
In this four-day activity, learners grow bacteria and/or fungi from a variety of locations and compare the results.

When Pigs Fly
Source Institutions
In this math lesson, learners explore probability.

Gummy Growth
Source Institutions
In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.

Traveling Nanoparticles Model
Source Institutions
This is an activity (located on page 3 of the PDF under Nanosilver Activity) about diffusion of small molecules across cell membranes.

Diffusion of Water with Gummy Bears
Source Institutions
In this activity, learners investigate the movement of water into and out of a polymer. Learners test the diffusion of water through gummy bears, which are made of sugar and gelatin (a polymer).

Recycle Your Own Paper!
Source Institutions
In this activity (page 2 of PDF under GPS: Garbology Activity), learners will prepare sheets of homemade recycled paper from several different source pulps.

Wild Sourdough
Source Institutions
In this activity, learners explore chemistry and the microbial world by making their own sourdough starter and bread at home using only flour and water.

Construction and Destruction
Source Institutions
In this three/four-day lesson, learners calculate perimeters and areas and draw the castle plan to scale.

Backyard Biodiesel
Source Institutions
In this activity, learners make a small batch of biodiesel that will work in any diesel engine. Learners use an old juice bottle as a "reactor" vessel to chemically process vegetable oil into fuel.
Hexagon Hunt
Source Institutions
This activity gets learners looking at 6-sided shapes in nature, including the cells of a beehive, as well as other shapes.

Handwashing Laboratory Activities: Bowl Technique
Source Institutions
In this lab (Activity #2 on page), learners compare bacteria growth on two petri dishes containing nutrient agar. Learners touch the doors, faucets, etc.

A Swell Activity with Beans
Source Institutions
In this combination chemistry and physics activity, learners explore water absorption in dried beans or peas and learn how this affects their physical properties.

Pesticides and Eggshell Thinning
Source Institutions
This lab activity is about toxic substances like pesticides and their effects on biological systems. The activity starts with an introduction of how birds sequester calcium to make an egg.

Percentage of Oxygen in the Air
Source Institutions
In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.
