In this nutrition activity (page 3 of the PDF), learners will record their food consumption for one day, and then evaluate how their actual diet matched up with the recommended diet.

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.

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

In this yummy chemistry activity which requires adult supervision, learners use sugar and water to explore how crystals form.

In this activity, learners make their own rock candy. Crystals will grow from a piece of string hanging in a cup of sugar water. The edible crystals may take up to a week to form.

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 chemistry activity (page 3 of the PDF), learners will learn about crystals by growing their very own.

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 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 activity, learners discover the primary physical properties used to separate pure substances from mixtures.

Eggs are placed in vinegar for one or two days to dissolve the shells. Then, learners place the eggs in water or corn syrup and observe them over a period of days.

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, learners explore engineering package designs that meet the needs of safely shipping a product.

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 activity, learners explore how packaging engineers develop customized shipping and packaging containers to meet the needs of many different industries.

In this activity (on page 2 of the PDF), learners make a plastic protein polymer from milk. Adding vinegar to milk causes the protein casein to solidify or curdle.
