Opti-Top
Source Institutions
In this activity, learners will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.

Static Water
Source Institutions
In this activity, learners will use static elecricity to bend a stream of water without touching it. Learners will explore physics and cause and effect through this activity.
Narrow It Down: Asking Yes-No Questions
Source Institutions
In this activity, the learner asks yes-no questions to identify a secret object (similar to Twenty Questions). This game is easy to adapt for different ages and different kinds of contexts.

Constellation Viewer
Source Institutions
In this activity, learners will explore what a constellation is and make their own.

Animal Guess Who
Source Institutions
In this game, learners take turns guessing toy animals from around their house based on the toy's characteristics.

Explore Like a Scientist: Fruity Observations
Source Institutions
In this activity, learners use their senses to collect information about a fruit and record their findings in a Science Journal.
Penny Jar: Estimating for Charity
Source Institutions
Learners will collect pennies to donate and will combine charitable giving with estimating and calculating with money. To start choose a charity or something to save up for together.

Atoms and Matter (K-2)
Source Institutions
In this activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.

Boats Afloat
Source Institutions
In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.

Chromatography Observations
Source Institutions
In this activity, learners will explore how water affects marker on filter paper. Learners will use science process skills such as making observations and predictions as they explore color.

Marine Skulls Cart
Source Institutions
In this activity, learners look at and touch marine animal skulls to compare them and think about what they eat.

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?

Creating a Soil Map
Source Institutions
In this activity, learners investigate soil conditions by creating a soil map. Learners record soil characteristics and compare the conditions of soil in different grid sections.

Clay Beams and Columns
Source Institutions
In this activity, learners make or use pre-made clay beams to scale and proportion. Specifically, they discover that when you scale up proportionally (i.e.

The Nose Knows
Source Institutions
In this activity (2nd activity on the page), learners explore how the nose is responsible for part of the flavor we taste in food.

Investigating Ice Worlds
Source Institutions
In this activity about the solar system, learners use various light sources to examine ice with different components to understand how NASA studies planets and moons from space.

Roller Coasters
Source Institutions
In this activity learners will build roller coasters and test them using small balls or marbles.

Animal Tape Rescue
Source Institutions
In this activity learners will "rescue" animals from tape and then sort the animals. Learners will use science process skills such as categorizing and making observations while they play.

Globe at Night
Source Institutions
In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

Wonderful Weather
Source Institutions
In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.
