Elementary-aged scientists discover that all matter has mass. They are shown the difference between mass and weight, and learn how to calculate mass using the appropriate tools and methods. The scientific method is used while estimating...

High schoolers determine the linear equations of the density of water and oil by collecting data on the mass of various volumes of each liquid. They construct scatter plots from the data and use these to write the linear equations for...

Learners describe and classify rocks that they have chosen. They estimate and find the mass of their rocks.

Here is a lesson that rocks! Young scientists choose a rock and list words that describe it. They estimate the mass of their rocks and rank them within a group. They measure their rocks for volume and write a story that somehow includes...

Pupils, after identifying and examining the relationship of temperature and air masses in association with smog and pollution, create a temperature inversion in a long aquarium jar. They experience what happens when smog builds up and no...

Learners participate in a series of demonstrations about Bernoulli's principle. They explain how air pressure varies with air speed. They write a detailed lab report about the activity. This is a great way to explore this concept.

Students familiarize themselves, through teacher demonstration, with Gavendish's apparatus first used for experimentally determining the value of the Universal Gravitational Constant G, and calculate theoretical value of Earth's...

Scientists participate in a variety of hands-on experiments in this ten-day unit on the three states of matter. Lessons incorporate literature, a-v materials, and poetry to help students differentiate between solids, liquids and gases.

Students recognize the three main types of clouds. In this clouds lesson plan, students create a cloud mobile to understand clouds.

Students explore clouds.  In this weather lesson, students identify the steps in the water cycle, define condensation and evaporation, and relate this information to cloud formation.  Students perform a cloud experiment,...

Students investigate the life cycle of a star and make conclusions based on evidence, research, and observation.  In this lesson plan on space and scientific investigation, students describe the relationships between science and...

Students explain the components that make up a hurricane.

Students examine cloud types. In this cloud lesson, students identify cloud types, observe clouds and collect data, and analyze data to identify the most common cloud they observe overhead during the course of a month.

Students create a model of a glacier and observe how it moves. In this landforms lesson, students learn what a glacier is, build a model glacier and observe how it moves in a manner that more closely resembles a liquid than a solid.

Students use a thermometer to analyze soil temperature data to determine which soil sample is normal, and which one is permafrost. In this permafrost lesson plan, students participate in a hands on activity where they identify the active...

Students conduct an experiment that shows them how salt water allows things to float. In this salt water lesson plan, students mix ingredients together to create salt water and observe how it makes the oceans dense. They then interpret...

Young scholars, in small groups, research Eratosthenes and his calculations of the Earth's radius. They write a summary of the person, the experiments and his calculations to determine how accurate Eratosthenes was in his estimations of...

Students create a torn paper landscape and use it to study clouds. In this cloud study and art lesson, students make a background art image from torn paper. Students create a torn paper landscape and use cotton balls to illustrate...

Students study and illustrate clouds. In this cloud study lesson, students study clouds and then illustrate what they see. Students use their imaginations to interpret images from the cloud picture they drew.
