Learners examine the style of an 18th-century compound microscope and its case. In this scientific design lesson plan, students look at Jacques Caffieri's, "Compound Microscope and Case" before comparing the design to a modern...

In this mighty microbes worksheet, students read for comprehension assessment. In this fill-in-the-blank and true and false worksheet, students answer ten questions.

Each of the 9 slides have a list of possible careers within areas of the Health industry.  There are no explanations or details of any of the jobs and so this would be useful to introduce the areas and then let the students research...

In this muscles worksheet, students describe characteristics of the three types of muscle and the function of each. Then they describe the gross and microscopic anatomy of skeletal muscle. Students also describe the steps that occur in a...

Here is a lab activity adequate for use with any full lesson on environmental factors that shape animal adaptations or marine animal characteristics. Pupils will discuss the role plankton plays in the environment and filter-feeding...

Here is a lab that has teenage scientists examining samples of their own blood under a microscope. Learners carefully prepare slides, then make detailed observations and identifying different types of cells using a key. 

Here is a lab activity where teens experience the respiratory system first-hand as they dissect lungs and identify key structures within the system. Although the website is written in British English with some slightly different verbiage...

Students observe organisms found in pond water with a microscope. In groups, they discuss how single-celled organisms satisfy their needs for food, water and air. They compare and contrast the needs of macroscopic and microscopic...

Students explore biology by participating in a fun science experiment. For this DNA lesson, students discuss what DNA is and where it comes from. Students utilize two bananas, a blender and a microscope to view the DNA of a banana in class.

Complete with teachers' notes for most of the slides, this is a tremendous presentation of the four types of tissues: epithelial, connective, nerve, and muscle. Each is displayed with pertinent vocabulary and photos of microscope slides...

They're everywhere! They're everywhere! Prokaryotes cover the Earth! Biology buffs survey the microscopic world of bacteria, including their general structure, metabolism, commercial uses, and diseases caused by pathogenic varieties....

Solids, liquid, and gas, the three states of matter, are the subject of a cross-curricular reading comprehension exercise that asks kids to first read an article about these forms, and then to respond to a series of questions based on...

Students observe the effects of eutrophication and determine why it is harmful to aquatic ecosystems. They create mason jar ecosystems to observe the growth of algae in pond water. In addition, they observe the effect of introducing...

Humans have only inhabited the earth for a fraction of the time that life has existed. Young scientists explore the facts about the emergence of life on Earth with an interactive resource. While highlighting different types of life, the...

Students build plankton models and compete to see which sinks most slowly. They write, or orally present ,the adaptations they incorporated to slow the sinking rate of their organisms. Race results can be grounds for some prizes!

Students experience a "hands-on" activity to get visual evidence of the physical nature of DNA and the process of DNA purification. They explore one method of chromosomal DNA isolation and DNA extraction.

Learners conduct a simulation to explore how scientists estimate the size of animal populations. They analyze a random sample and then extrapolate those results to a larger population. Additionally, they will apply the principals of...

Explore the scientific method of classification. An interactive activity asks learners to create a classification system for a group of objects and develop a flow chart to communicate their systems. In addition, individuals use a...

Students prepare a slide of Paramecium cultures and observe (through a microscope) the organism's thin transparent membrane and what happens as they "feed" them stained yeast cells. They sketch the path the ingested yeast takes as it...

Students observe the reaction of living cells to mechanical and chemical stimuli by introducing different stimuli to an organism under a microscope and recording the response.

Students discover and discuss the differences between prokaryotes and eukaryotes. Using a microscope, they examine various prepared slides of prokaryotic and eukaryotic organisms.

Students isolate DNA from different food sources. In this biology lesson, students research DNA extraction. They analyze DNA stands collected from the lab, and compare the differences between each.

Students prepare successful wet mount slide of Elodea. They determine and identify environmental conditions that induce cytoplasmic streaming. They determine the positive aspects of cytoplasmic streaming. They illustrate knowledge and...

Young scholars observe the wealth of living organisms in a drop of water from our freshwater ecosystems. They classify the types of organisms observed as single-celled or multi-cellular and use a key or chart to identify and name the...
