In this activity, learners use food scraps from the kitchen to grow new vegetables.

In this physics activity, learners build their own rockets out of film canisters and construction paper.

The goal of this activity is to build a miniature bobsled that is either the fastest or the slowest. Learners use recycled materials to design, build, and test their bobsled on a bobsled track.

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

Learners make a skydiver and parachute contraption and launch it. They see that the drag created by air resistance slows the descent of skydivers as they travel back to Earth.

In this activity, learners recreate a method of detecting and correcting errors in computers called 'parity'.

In this activity, learners will build a design and build a place for pollinators to drink from.

This fun and simple hands-on astronomy activity lets learners make 3-dimensional models of the Earth and Moon.

In this activity, learners make a model of a one-way heart valve to investigate how a heart controls the direction of blood flow.

Doctors often send a sample of blood to a lab, to make sure their patients are healthy.

In this activity, learners manipulate paper to build original 3-dimensional sculptures. Appropriate for any age, learners can use fingers to tear, crumple, or fold, and if available, scissors to cut.

This activity is about the mural making process done about 9,000 years ago in Catalhoyuk, Turkey.

In this geology activity (page 3 of the PDF), learners simulate an earthquake with little more than an elastic band and drinking straws.

In this activity, learners will create their own simple shadow puppets, and experiment with light and shadow while playing with them.

In this activity, learners explore and compare the buoyant properties of materials found in nature and in human-made materials.

In this activity, learners will reuse plastic bags in an interesting way.

In this activity, learners will dissect a pumpkin or winter squash to learn the parts of the plant. This activity gets your learner hands on with every part of the plant and will be messy.

Many people get water from a source deep underground, called groundwater.

In this activity, learners construct speedy vehicles made out of paper plates and powered by twisted rubber bands.

In this tabletop board game, players will represent a team of scientists and engineers sending a spacecraft on a mission to space.
