In this activity, learners simulate a multistage rocket launch using party balloons, fishing line, straws, and a plastic cup.

This is a demonstration about how nature inspires nanotechnology. It is easily adapted into a hands-on activity for an individual or groups.

In this online activity about heart disease, learners will, with the virtual help of an actual surgeon, watch a virtual bypass surgery.

In this activity, learners conduct an experiment to find the volume of one mole of gas. Learners capture sublimated gas from dry ice in a ziploc bag and use water displacement to measure its volume.

In this activity, learners explore how eating unhealthy food can damage a heart and arteries.

This fun and simple hands-on astronomy activity lets learners experiment with a bucket, stretchy fabric, marbles, and weights to discover some basics about gravity.

In this activity, learners explore how sound travels through solid objects better than through air. Leaners attach a metal clothes hanger to a piece of string and hold it to their ears.

In this activity, learners conduct a simple experiment to see how electrically charged things like plastic attract electrically neutral things like water.

In this design challenge activity, learners explore the concept of biomimicry by using a natural organism's special features to design a new human object.

This fun and simple hands-on astronomy activity describes techniques scientists use to find planets orbiting other stars.

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

In this activity, learners interact with whale artifacts such as replicas of skulls, bones, teeth, and baleen (hair-like plates that form a feeding filter).

This activity lets learners participate in the process of reconstructing a phylogenetic tree and introduces them to several core bioinformatics concepts, particularly in relation to evolution.

In this activity, learners use molecular model kits to construct familiar molecules like lactose, caffeine, and Aspirin.

Learners construct a bracelet containing two strands of beads, which represents a double strand of DNA that codes for a gene. They match beads to the bases in a section of a chimp's DNA code.

In this activity, learners use basic measurements of the Earth and pieces of rock and iron to estimate the mass of the Earth.

Learners make a mobile model of a carbon atom using clay, wire, and pipe cleaners.

Spin a short piece of PVC pipe that's been marked up, and watch a triangle appear. Enjoy this optical illusion from the Exploratorium's Science Snack series.

In this activity, learners light an LED with five cents. Learners use two different metals and some sour, salty water to create a cheap battery.

In this activity, learners explore how engineering has impacted the development of bridges over time, including innovative designs and the challenge of creating bridges that become landmarks for a cit
