First graders access prior knowledge about pumpkins and read the story Pumpkin, Pumpkin. They will sequence the life cycle of the pumpkin through the use of picture cards and then sing a song about the life cycle of the pumpkin and plant...

Learners explore concepts of probability and independent events. They develop a formula for deviation percentage.

Set up a demonstration of how gravity can drive the perpetual flow of water during your hydro power unit. Science learners work in teams to make observations and formulate questions about how it works. They compare the model to what they...

Sixth graders discuss the crowding, loss of personal space, loss of home, loss of food, etc. that might occur at a developmental site. They witness, through an in-class demonstration, what happens when land is taken for development. They...

Fourth graders observe demonstrations how heated air rises and becomes a low pressure area. After watching several teacher-conducted experiments, 4th graders, in groups, discuss and answer questions in their journals. Finally, they...

Students estimate how many drops of water can fit onto the surface of a penny and then test their hypothesis to find out. They also experiment with bubbles.

Students visualize the relation between acceleration and velocity in 2 dimensions. They are introduced to Newton's first law,and Newton's second law. Students work on an exploration activity where they condsider an example of a...

Fourth graders discover earth's air pressure through observation of several experiments. In the "Experiment of the Leaky Bottle," they observe how air pressure forces water out of the lowest hole farther than the holes above it. In...

Students identify the control and the variables in the experiment. They describe the growth of plants with and without nitrogen fixing bacteria, then name the bacterium responsible for making nitrogen available to the plant.

In this reading comprehension instructional activity, 3rd graders read four different passages about Science News. They answer questions about each one. Students complete 4 comprehension questions.

Fourth graders create spreadsheets, explore patterns and make predictions based on the information. They select the appropriate graph to display the spreadsheet data. They search and sort prepared data bases to gain knowledge for...

Students hypothesize the location of the sun in the sky at diferent times of day and at different latitudes. They perform several experiments to provide evidence for their hypothesis. Experiments including observing the sun's position at...

Students discover how molecules are in constant motion. Through a simple experiment of water containing food coloring, they observe the drops of coloring move even though the water is still. Role-playing as molecules, students stand up...

Students assess how much harm UV radiation can have on your skin and how much protection is provided by sunblock, sunglasses and clothing. They experiment with UV index numbers and the amount of exposure risk of skin damage for any given...

Planning a party of 45 guests may be more complicated than it would seem.  Learners must design the space in accordance with these constraints about the space available in the room. They need to calculate area, circumference,...

There's a high likelihood for learner success in this set of probability problems and activities. From support activities that walk learners through joint and compound probabilities through the cumulative activity of planning to win...

Find out the characteristics that makes a bug an insect with a workbook designed to inform scholars about the crawly creatures that live around us. Scholars complete an ant-themed word search, answer questions using a solution key,...

Students explore how compass and Gauss meter detect a magnetic field. In this physics lesson, students build their own Gauss meter and sensor based on given procedure. They cite real world applications of magnetism.

Students explore the concept that not all light is visible to the human eye. Although UV light is not visible, it can still be harmful, causing sunburns or skin cancer. They use special beads to detect UV light around the school....

Students build the Voyage scale model of the Solar System on a playground and "travel" to each planet. They recognize that the Sun and planets are tiny worlds in a vast space, giving them a new perspective on the Solar System, and...

Students experience and participate in a journey through a "Voyage" exhibition of the Solar System and the frontier it covers. They build a dynamic model of the Earth and Sun. Descriptions are given on the relative sizes of the Sun and...

High schoolers investigate oxidation-reduction reactions involving iron by conducting an experiment in which they expose iron filings to different atmospheric and ocean conditions. They relate the results to the oxidation banding...

Students understand how clouds are formed. In this cloud lesson, students participate in three experiments to make clouds. Students complete activity sheets for each experiment.

Students design an experiment for NASA's STEREO/IMPACT mission to measure the interplanetary magnetic field. This lesson includes 3 excellent hands-on and critical thinking activities in which students explore magnetism in the solar wind.
