Fourth graders study the properties of heat in this series of lessons. They discuss sources of heat and experiment to determine its properties. They identify insulators and conductors by measuring temperatures, and graphing their data....

Learners investigate buoyancy, displacement and density.  In this flotation lesson students study the Archimedes' Principle, analyze data and draw conclusions. 

Students investigate landforms by holding a class experiment. In this topography lesson, students define the word "karst" and discover why sinkholes are created on the surface of the Earth by completing worksheets. Students create a...

Students perform an experiment to find out if plants grow best when grown in soil with no fertilizer, with chemical fertilizers, or with compost that they have made themselves. Students discover how agriculture practices can benefit the...

Young scholars investigate the cooling and heating of water. In this online science experiment lesson, students work in groups to make predictions regarding freezing and boiling points and then test those predictions as they complete the...

Fourth graders determine, through laboratory activity, the presence or absence of glucose in a variety of plant leaves and stems. They work in groups and perform a three part laboratory which shows them how plants convert sunlighht to food.

Learners formulate their own hypothesis, determine which variables are important to test their hypothesis, design an experiment in which they collect data. They utilize instruments and tools to measure, calculate, and organize data.

Students complete activities to study wind intensity. In this wind study instructional activity, students discuss wind speed and direction. Students then build a kite and windsock to help them study wind intensity. Students learn to use...

Second graders become familiar with the lives of penguins including their life cycles, habitats and basic needs. Students will experience the lives of penguins through stories and video.

Learners predict the behavior of coffee in a cup while it is dropped during a demonstration. They relate their observations to the weightless conditions that astronauts experience in space and discuss the concept of free-fall.

Young scholars experience and practice compositing and recycling through hands-on-activities. They distinguish between which items from their trash can be recycled, composted and reused. The process for making recycled paper is also...

High schoolers design an experiment to see how wind, temperature, and salinity work together to influence ocean currents and present it in a report format. They explain to their classmates how experiment findings relate to ocean currents.

Students conduct an experiment to demonstrate that many of the enzyme systems needed to break down society's wastes exist in nature among the decomposers in a compost pile. They culture compost bacteria on starch agar to examine the...

Students demonstrate that many of the enzyme systems needed to break down--and therefore clean up-society's wastes already exist in nature among the decomposers. They select the best starch-munching organisms by altering the environment...

Students using experiments try to demonstrate how observations can be affected by the cycles of night and day.

Students use the scientific inquiry method to identify the changes in a plant's life cycle. In groups, they plant different types of plants and use a chart to compare and contrast their growth rates. They share their conclusions with...

Students participate in an experiment in which they test the growth of different types of plants. They discover how growth rates vary using inoculum. They draw pictures and are read books about plants to end the lesson.

Fourth graders investigate how weather influences shelter choices. They explore the concept of insulation and discuss some traditional Native American shelters. They discuss the shelters used by the Okanogan people during the various...

Students experiment with Drosophila to determine if density of female flies, food sources, temperature and light affect the population dynamics of growth. Students graph their data and compare their results to the number of human...

Students study how clouds form, what different types there are and what rain is.  In this atmospheric instructional activity students make a cloud and create evaporation.

Students investigate various chemical reactions when creating mixtures in ziplock baggies. In this chemistry lesson, students will recognize various chemical reactions and cite evidence. Safety and assessment strategies are included in...

Students seek scientific and technological solutions to envrionmental problems. They record class activities in a journal. They identify relationships among living things and their environments.

Students view a video and then complete lab exercises to help them explain marine communities and animals in them.

Young scholars examine how to conduct simple investigations and use simple equipment to gather data.  For this magnet lesson students decide what types of objects are attracted to magnets.
