Liquid Lava Layers
Source Institutions
In this activity, learners explore the concepts of density and basic chemical reactions as they create a homemade lava lamp effect using water, oil, food coloring, and Alka-Seltzer tablets.
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.
Inverted Bottles
Source Institutions
In this activity, learners investigate convection by using food coloring and water of different temperatures.
Painting a Picture with Air
Source Institutions
Create a painting by blowing air out of a straw. Push liquid acrylic paint around on some watercolor paper by aiming short bursts of air onto the paint puddle.
Storm Water Runoff Pollution
Source Institutions
This activity (located on page 8 of the PDF) introduces learners to the concept of Non-point Source Pollution--what happens when rain washes garbage and other pollutants into rivers and lakes.
Who Eats What?
Source Institutions
This activity is on page 10 (continued on the right side of page 11) of the pdf, part of the Forest Animals Discovery Box. In this game, learners act out the food web.
Condiment Diver
Source Institutions
In this hands-on activity, learners make the world's simplest Cartesian diver, using only a plastic bottle, some water, and a condiment packet.
Using Different Models of Earth
Source Institutions
In this activity, learners explore how the shapes, sizes, and distances of land masses appear differently on two different models of Earth: an icosahedron and a flat map.
Paper Table
Source Institutions
In this design challenge activity, learners use tubes of newspaper to make a table that’s at least eight inches tall and strong enough to hold a heavy book!
Defining Dissolving
Source Institutions
In this introductory activity, learners discover that sugar and food coloring dissolve in water but neither dissolves in oil.
Cauldron Bubbles
Source Institutions
In this activity, learners mix up a bubbly brew and examine density. Learners explore how they can make different materials fall and rise in water using oil, water, and salt.
Pom-Pom Probability
Source Institutions
In this math activity, learners predict how many pom-poms they can toss inside a circle from three feet away. Use this activity to help learners explore probability.
Super Golf Tower
Source Institutions
In this engineering activity, challenge learners to build a tower out of 10 sheets of newspaper and 3 feet of masking tape, which can hold a golf ball balancing at the top.
Auditory Acuity
Source Institutions
This activity (8th activity on the page) tests learners' ability to identify things using only the sense of hearing.
Physics by the Fire: Matchstick Rocket
Source Institutions
Learners build a small rocket using a matchstick and a piece of aluminum foil. A second, lit match launches the match rocket. This activity involves fire; adult supervision required.
Two Sets!
Source Institutions
In this card game, learners make two sets of three cards that are alike. Learners must justify to the rest of the players why the three cards belong in each set.
How Fast Are You?
Source Institutions
This activity is designed to let learners measure their reaction time or response time to something they see.
Spots, Lines and Lasers
Source Institutions
Learners shine the light of a laser pointer through sheets of fabric that all have a different number of threads per inch.
Hot Potato
Source Institutions
In this health activity (page 7 of the PDF), learners will discover the importance of handwashing as a factor in reducing the spread of pathogens.
Gecko Feet
Source Institutions
This is an activity (located on page 3 of PDF under Gecko Feet Activity) about modeling a nanoscale phenomenon (gravity-defying gecko feet) with macroscale objects (shoes).
