In this activity, learners will explore vegetative propagation while preparing food scraps to grow into plants.

This is a hands-on activity that uses bread and household materials to grow mold. Learners collect dust from a room, wipe it on food, and contain it. One to seven days later, mold has grown.

In this four-day activity, learners grow bacteria and/or fungi from a variety of locations and compare the results.

This activity helps the learner answer the question: "What environmental problems arise due to animal and human overpopulation and what might need to be done to combat these problems?" Learners play a

Learners make a "menu" of any plants in their lunch for Monday through Friday and draw the plants from their lunch.

Learners place cut flowers in colored water and observe how the flowers change. The flowers absorb the water through the stem and leaves.

In this activity, learners conduct a series of hands-on experiments that demonstrate how the working of plants' veins, known as capillary action, enables water to travel throughout the length of a pla

In this construction activity, students use a 2-liter bottle to build a fly trap.

Just like birds, some dinosaurs had air-filled (pneumatic) bones, which made the dinosaurs' skeletons lighter.

In this activity, learners build a model of a self-sustaining habitat (growing grass and beans from seeds).

In this chemistry activity (page 8 of the PDF), learners will identify the instances of physical change, chemical change, and solutions while making homemade soda pop.

In this environmental health activity, learners grow and observe bread mold and other kinds of common fungi over the course of 3-7 days.

This activity features two connected hands-on activities about dinosaur bones.

In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.

In this design challenge, learners will use microbes to design and grow a custom biomaterial at home and make something creative with it.

In this laboratory activity, learners design an experiment to evaluate how environmental factors influence the growth of molds.

In this activity on page 8 of the PDF (Behind the Scenes with Chemistry), learners make three of Harry Potter's essential school supplies: quills, ink, and color-changing paper.

In this four-part laboratory exercise, learners investigate properties of Tobacco mosaic virus (TMV) including (1) symptoms induced by the virus in susceptible plants at the macroscopic and microscopi
