While this activity is based on the Bruchid beetle, the focus is on conducting a scientific investigation. Ecology explorers vary the temperature or the type of leaf that Bruchid eggs are laid on and test for effects on the development...

Although the worksheet for the lab activity is not included, this is an activating activity for your class to do when learning about the greenhouse effect. They lay three thermometers underneath a lamp: one out in the open, one under a...

Learners examine pollution and how it affects the environment. They discuss how human activities lead to more pollution. They talk about the importance of recycling. There is a skit, resource links, and activities provided to make this a...

The central video for this lesson is not available through the included resource link. However, the activity that simulates the passing of a virus through a population is impacting and the other resource links are invaluable. Use this...

Students participate in an activity in which they investigate the scientific method and seed germination as well as practice graphing and metric measuring skills. Students examine toxicity by exposing Wisconsin Fast Plants seeds to toxic...

Beginning biologists place a drop of food coloring into water of differing temperatures to observe the effect on the diffusion rate. They remove the shells from raw eggs and then experiment with osmosis over the remaining membranes....

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.

Students Explain how an increased level of activity translates to cells needing more oxygen and how the lungs supply this oxygen by entering the blood stream. They also can explain that the heart is responsible for moving both oxygenated...

Very simply, pairs of learners construct a model of the tetrahedral silica structure using raisins and toothpicks. They dip it into a soapy solution and then blow a bubble "atom" into its center. The lesson plan gives instructions that...

A simple activity goes a long way in demonstrating the property of porosity to your rock hounds. They will mass a specimen of dry sandstone and then soak it in a pre-measured amount of water. After seven minutes, they once again measure...

Students build a scaled model of the solar system. In this space science lesson plan, students arrange them according to their distances from the sun. They analyze each planet's unique features such as density and relative gravity.

Elementary schoolers identify the three methods of heat transfer: conduction, convection, and radiation. The lesson is mostly lecture-based. When the teacher has finished the presentation, groups of pupils get into teams and they must...

Immerse your young marine biologists in the world of marine animals. The instructional activity includes several activities that are age-appropriate for preschoolers and kindergartners, including coloring pages, gluing feathers and sand...

New Horizons began its journey to Pluto in 2006. Ten years later, it continues its mission. In that time, scholars have surely grown, but how much more will they grow by the time New Horizons reaches its destination? Find out with an...

Here is an interesting science lesson/activity which has learners working in groups in order to simulate experiments done at the Jefferson Science Lab. In this one, groups use a pie tin, a Hula Hoops, a marble, and a magic marker to...

Third graders make alphabet cards that depict the wide variety of life forms found in the Sonoran Desert. A terrific lesson that combines language arts, visual arts, and life science all into one wonderful package. Each of the cards has...

Young scientists explore the world of dinosaurs. They engage in a variety of activities designed to help correct misconceptions about dinosaurs, and which help them to determine which animals are dinosaurs and which are not. There is a...

High schoolers determine the normal behavior of California blackworms. They determine how various concentrations of assigned toxicants affect the worm's behavior. Students are introduced to testing of potential toxicants, an important...

Requiring more than one class period, this resource takes earth science learners on a journey through a watershed. Using ArcGIS Explorer, an online geographic information system, they view maps of watersheds and surrounding landscapes....

Pupils complete various activities to investigate growing apples. They examine words related to apple growth and write the words on apple shapes. They also take a vocabulary quiz and complete an apple concentration game. Next, they watch...

Students study cloud data and weather maps to explore cloud activity.  For this cloud data lesson students locate latitude and longitude coordinates and determine cloud cover percentages. 

Students examine how living cells reproduce to make new cells.  In this cell reproduction lesson students complete a lab activity and answer questions. 

Rally your administration and facilities manager to let your class examine the water flow rates in different areas of the school. After the audit, the class researches opportunites for conserving water and writes a report or develops a...

Teams of electrical engineers work together to develop plans for increasing electricity to a fictitious, but growing community. They consider different sources of electricity, both renewable and nonrenewable, the cost of building and...
