Students examine Morse code and how it is used.  In this secret codes lesson students decode messages, make their own codes and have other students crack the code.    

Students work together to review the concepts of food webs and food chains. They describe the role of plants and animals when dealing with the cycling of energy. They identify any behavioural strategies to help the animals survive.

Students investigate techniques that can be used to observe the development of the chick embryo. They explore the environment in which the chick develops and how it can be manipulated.

Students use their senses to compare a frog and a hamster. In this animals comparison lesson plan, students get into groups and observe, smell, feel, and listen to what their animals are like, and classify them into categories.

Students identify different woods based on their density. In this density lesson, students use a triple beam balance to find the mass and a metric ruler for the volume. They look through various wood blocks and identify what type of wood...

Students observe and classify objects that float or sink.

Students examine the definition of species. Students complete a phylogentic tree of the Canidae family. They write an essay justifying why or why not wolves and dogs should be classified as different species.

In this biodiversity worksheet, students sort and classify animals by their observable features using a dichotomous key. Students then respond to questions about complete and incomplete metamorphosis.

Students explore different types of trees. In this tree lesson, students use a digital camera to photograph trees in their area and upload them to a computer. Students will share their findings by using their photos to make a booklet or...

In this resource lesson plan, students use non-fiction books to research ocean animals. Students discover the many features of non-fiction books and how to use these features to help them conduct research. Students then categorize...

Students distinguish between walking, jogging and running trackways in humans. They analyze the phylogenetic progression of the leg position as described by pace width and angulation, comparing amphibians, reptiles and mammals. Research...

Students investigate the basic characteristics of insect orders and develop short-cut techniques to identify insects into twelve of the most common orders. They use captured specimens and photographs to practice identification and then...

Young scientists use the Internet to evaluate how organisms are classified. They research the phylogeny of organisms and how they are linked in a certain way. Pupils hone research technology skills with their final presentations.

In this biology worksheet, students complete 19 short answer questions about biodiversity and information obtained during a class video.

Students examine photographs of closely related species found in the Gal??pagos environment, observe differences and similarities between species, and form hypotheses about species differences and the relationship to the environment of...

Students organize different species of plans and animals according to various characteristics. Students then determine what characteristics enable them to survive in their habitat. Game ideas and activities are included.

Students explore invasive species on an environment.  In this exploratory lesson students hypothesize why shrimp are on the decline and make a brochure or poster showing their results. 

Students identify characteristics of birds, name several species, and explain how birds fly. They make nests and give bird presentations.

Students compile baseline population information on a local species. They design and conduct a scientific investigation of a local species. Students interpret, analyze and communicate results based on sound scientific and mathematical...

Learners discuss ten important Pennsylvania hardwood trees, examine characteristics of each tree species, evaluate economic and ecological importance of hardwood trees, and recognize at least two characteristics of each species.

Students examine the effect of foreign species on various habitats. In groups, they identify the population dynamics of the zebra mussel. They calculate averages and graph data from Seneca Lake in New York. They develop hypothesis...

Students compile an extensive list of animal species seen throughout Tioga County. In this data collecting lesson, students report daily any animal species seen during the course of their travels and adventures outdoors in Tioga County...

Students examine the cell cycle and how its duration can vary.  In this cells lesson students complete a worksheet and answer questions. 

First graders compare and contrast adult and baby animals to identify similar characteristics shared by both.
