In this activity, learners will explore how their own eyes work by experimenting with their photoreceptors.

In this physics activity, learners experiment with soap bubbles to see what variables affect their size. They explore how soap film and bubbles always seek the smallest surface area possible.

In this activity on page 3 of the PDF, learners investigate how much sugar is in a soda. Learners use sugar cubes to measure and calculate the amount of sugar in a bottle of soda.

In this introductory activity and demonstration, learners are introduced to the concept that different substances react chemically in characteristic ways.

Using information from the My Place in Space lithograph, learners write and/or draw a postcard to friends and family as if they had gone beyond the interstellar boundary of our Solar System, into the

In this math activity, learners observe and sketch cracking patterns in pavement.

In this activity, learners explore how polarizing sunglasses can help diminish road glare.

In this activity, learners work in partners to create and exchange messages written in Braille. Learners use a Braille key and thumbtacks to write their messages in Braille.

In this activity, learners cutout a set of shape finder templates to explore shapes in the world around them.

In this activity, learners will dip different items in paint and then roll those items down a ramp. Learners will use science process skills such as observations and experimenting.

This activity aims to stimulate discussion on the question of whether computers can exhibit “intelligence,” or are ever likely to do so in the future.

In this activity, learners test different food items by timing how long it takes each liquid to slide from the top of a ramp to the bottom.

In this activity on page 13 of the PDF, use a special plastic card that has been painted with a chemical that changes color when it is in UV light.

In this activity, learners make their own pinhole viewer in order to measure the size of the sun.

This game teaches ratio and proportion by having learners make "salads" that combine three types of beans in different combinations.

In this activity, early learners combine pre-cut recognizable shapes and their own abstract ideas to make representational pictures (e.g. houses, trees, shoes).

In this activity, learners model a population of deer and see how the number of deer changes over time.
