Biology Lessons: Preschool – 5th grade

STEAM (Science Technology Engineering Arts Mathematics) lessons are adaptable to various developmental levels of students. Grades noted next to descriptions are mere recommendations.

Amazing Food Race

Students will learn how food goes from farm to table through activities and games.

Preschool–2nd grade

Students will compare and contrast animals’ homes above or below the ground and construct an animal home.

Preschool–5th grade

Animal Tracks

Students will discover that through keen observation of our surroundings coupled with logical thinking we can draw a conclusion as to what may have taken place prior to our arrival.

Preschool–3rd grade

Antarctica Animals

Students will examine the habitats of Antarctica animals and their adaptations.

Preschool–5th grade

Ant Strength

Students will observe intricate images of ant colonies, learn about the body structure and unique characteristics of an ant and then implement the engineering design process to construct an ant capable of holding a designated amount of weight.

1st–5th grade

Bee Communication

Students will examine the geometry of a bee”s nest and discover cross pollination through a series of activities and participate in a bee dance.

Preschool–5th grade

Bones and Me

Students will participate in activities that teach about health and exercise and what makes our bone strong and able to grow.

Preschool–5th grade

Building Beaches

Students will build a model beach and see how waves affect the shoreline of the beach.

2nd–5th grade

Building Dams; Be a Beaver

Students will be introduced to some of the issues engineers face in building dams: they must be both waterproof and strong enough to withstand the pressure of water.

2nd–5th grade

Dental Health and Hygiene

Students will participate in a series of activities that teach them how to brush, floss and eat healthy in order to have a healthy mouth.

Preschool–1st grade

Designed by Nature

Students will discover how engineers can use biomimicry to enhance their designs. They learn how the careful observation of nature—becoming a nature detective, so to speak—can lead to new innovations and products. In this activity, students reverse engineer a flower to glean design ideas for new products.

1st–5th grade

Do Ptarmigans Have Snowshoes

Students will investigate whether the feathers of the ptarmigan have a secondary adaptation—whether the feathers increase flotation like snowshoes do.

Kindergarten–5th grade

Engineer a Seed

Students will handle and observe a variety of seeds, discover why some sink, float and are carried by wind, then construct a seed from found objects that mimics a seed in nature.

Prekindergarten–5th grade

Environmental Interactions

Students will create a “web” to identify and demonstrate the interactions among the living and non-living parts of an environment.

Prekindergarten–5th grade

Fossil Formation

Students will explore real fossils, learn about how fossils are made and make a fossil to bring home.

2nd–5th grade

Fresh Water Animals

Students will learn the characteristics of salamander and turtles through hands-on activities.

Prekindergarten–3rd grade


Students will handle real animal furs, study animal habitats and learn the difference between true hibernation and torpor and classify animals accordingly.

Prekindergarten–5th grade

Human Brain

Students will discover the power of the human brain and the function of four main lobes through activities and projects.

Prekindergarten–5th grade

Let Your Ears Do the Walking

Students will experience a simulation of echolocation, using the sensory method to walk along a path while blindfolded.

Prekindergarten–5th grade

Live Like a Cactus

Students will be introduced to water conservation by learning about plant drought tolerance, how cacti have adapted to the desert environment and come up with some of their own designs based on these observations.

1st–5th grade

Loco Beans

Students will handle real jumping beans and learn the life cycle of the moth.

This activity is seasonal for the fall.

Prekindergarten–5th grade

Mystery Senses

Students will engage in mystery challenges that highlight their five senses.

Preschool–5th grade

Oil Spill Clean Up

Students will examine the environmental effects of oil in a lake and shoreline, then perform and oil spill clean up.

2nd–5th grade

Owl Pellets

Students will dissect owl pellets, classify bones and understand what owls eat.

Prekindergarten–5th grade


Students make snot and learn how mucous in our bodies helps to fight germs.

Preschool–5th grade

Something About Seeds

Students handle a variety of seeds, dissect seeds and discover how seeds are transported in nature.

Preschool–5th grade

Sound Mapping

Students will use their sense of hearing, students will discover the range of activities and inhabitants that occupy the space around their school grounds or nearby areas. The purpose of this lesson is to teach students how to draw and read a map using symbols and legends. It also helps them learn how to observe their surroundings thoughtfully using their senses, as well providing an introduction to categorizing species.

Prekindergarten–5th grade

STEM a Bird Beak!

Students will comprehend that birds have physically adapted in relation to their type of food supply and deduce what beaks are most efficient for given foods by experimenting with imitation beaks and creating beaks out of supplies.

1st–5th grade

STEM Nest!

Students will observe a variety of nests then put their engineering skills to the test. Finding inspiration in nature, students will design and construct a nest.

Preschool–5th grade

Super Stomach - Slurp, chomp, toot!

Students will learn about chemical and mechanical digestion through hands-on activities.

Preschool–5th grade

The Effects of Acid Rain

Students will conduct a simple experiment to model and explore the harmful effects of acid rain on living and non-living objects.

2 class periods approximately 4 days apart preferred.

2nd–5th grade

This Land is Your Land

Students will consider the environmental effects of the different types of land use. Students will act as community planning engineers to determine where to place a new structure that will have the least effect on the environment.

2-3 class periods recommended.

3rd–5th grade

To Be a Tree

Students will play a game to learn about the lifecycle of a tree, how trees impact our everyday lives and adopt a tree for the seasons.

Preschool–5th grade

Ugh a Bug

Students will go on a bug hunt, observe the difference between a bug and an insect, learn about predator and prey and make an insect to bring home.

Preschool–5th grade

Velcro Case Study

Students begin with a Case Study of biomimicry focused on Velcro technology, then construct physical replicas of burrs (the design inspiration for Velcro) and work in teams to run a relay race where they pick up and drop off their burr models using a ball of string.

3rd–5th grade


Students will handle ostrich and bison bones, observe animal x-rays from animals around the world and compare and contrast vertebrates and invertebrates.

Preschool–5th grade

Wiggle Worms

Students will handle earth worms and red compost worms as they make observations about the worm habitat and lifecycle.

Preschool–5th grade
