Students collect DNA from cheek cells. They compare and contrast the processes of DNA replication and PCR. They discuss how this information can be used to determine guilt at crime scenes.

Fourth graders explore the plant life cycle. They discuss the sequence of events in the life cycle of the plant and illustrate how the life cycle never ends. Students explore the importance of water, sunlight, and nutrients during the...

In this science activity, students match each type of scientist listed in the left-had column to its correct description found in the right-hand column. There are 34 different scientists to match on the sheet.

Students investigate the characteristics of living things. In this life science lesson, students examine several living and non-living specimens. Students determine which things are living and non-living.

Students are asked how does odors move around without energy? They relate concentration gradients, diffusion, and equilbrium and predict water movement into and out of cells. Students are shown a demonstration where the teacher sprays...

Students explore nutrition. In this science lesson plan, students identify and describe the main nutrients in our diets that are needed by the body as a source of energy.

Students determine that waves carry energy and information from one place to another. They determine that wavelength, frequency and wave speed are related and describe that sound is a longitudinal wave whose speed depends on the...

In this science worksheet, students match each of the descriptions on the right to the correct scientist listed on the right. There are thirty scientists to identify and match on the sheet.

Students define the key terms that are the structure and function of DNA. In this genetics lesson students complete a lab activity in which they construct a model DNA structure.

In this layer of the earth worksheet, students label and color each layer of the earth. Then students are asked to describe each layer below.

In this worksheet on the life cycle of the butterfly, students look at 4 pictures representing the life cycle stages, and choose words from a word box that match each picture. Students then number the pictures in the correct order of...

Study everything about plants! The 12-part series of lessons continues with an examination of many aspects of plants. Components of the laboratory activity address the growth and structure of plants by evaluating familiar plants. The...

Starting with definitions and terms related to how electricity flows, these slides assist in understanding of displacement reactions. Some typical displacement reactions that occur with a flow of electricity through a solution are...

Classify living things with a set of worksheets that has pupils sorting and indentifying living and non-living things. Learners use the worksheets as a basis for finding their answers. 

Students are given the unique opportunity to see the contrast between parts of a leaf that have photosynthesized and parts of the leaf that have not. This visual image helps students see the results of this biological process. At the...

Ten reactions involved with the process of glycolysis within cellular respiration are summarized here. The aerobic stages and anaerobic interactions leading to fermentation are detailed and wonderful diagrams to support the information...

How does electricity work? Budding scientists explore the concepts of electrical currents and open and closed circuits with class discussion and a hands-on activity using a battery to turn on a light bulb. Learners also make predictions...

A fantastic presentation with great images should improve student understanding of lipids and their involvement in the body.  The chemistry of different fats, phospholipids, and steroids are explained. Additionally, the specific...

How do temperature changes affect ocean currents? Scholars explore convection currents by demonstrating the flow of water in a baking dish. They use ice, heat, and food coloring to see currents. Then, they draw conclusions about their...

Fifth graders work in small groups to brainstorm responses to a problem related to some disaster that wipes out half or all plant life on earth. Groups complete a graphic organizer to compare and contrast their ideas. Students select...

A mix of scientific details and background information about the well-known sites of radiation attacks or accidents. This topic may open up details that you may consider as sensitive, and could be upsetting to some pupils. This is a...

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!

This presentation begins with the many problems multicellular organisms which rely on diffusion encounter. There are many diagrams of mammalian organ structures, and they are labelled with their relevant functions. This an excellent...

Information about digestion of various food components is given in this PowerPoint. The diets of herbivores and carnivores are compared, and there are many diagrams giving details of their digestive system specializations. The...
