Can you name the three planets with rings in our solar system? Everyone knows Saturn, many know Uranus, but most people are surprised to learn that Jupiter also has a ring. The third in a series of six teaches pupils what is around...

Huygens spacecraft landed on Saturn's moon Titan in 2005, making it the farthest landing from Earth ever made by a spacecraft. In this hands-on activity, the 12th installment of 22, groups explore how density affects speed. To do this,...

The density of the huge planet of Saturn is 0.7 g/cm3, which means it could float in water! In the second part of 22, science pupils explore the size and order of the planets. They then calculate weight and/or gravity and density of...

Explore optics using an inquiry-based experimental approach! Young scholars use a set of materials to design and build a unit capable of focusing a beam of light. They experiment with different lenses to determine the best approach to...

Twenty questions make up an assessment designed to test super scientists' knowledge of ecosystems. Scholars answer multiple-choice and short-answer questions about organisms, food chains, energy flow, and more.

Show us your moves. Using sensor equipment, scholars track the motion of different movements, such as jogging, skipping, or jump roping. They analyze velocity and acceleration and create graphs representing each movement.

First in a two-part instructional activity on the greenhouse effect, this instructional activity involves a classroom demonstration of the phenomenon, and a lab group experiment with color and absorption. Although there are easier ways...

We all know limestone weathers, but what affects the rate of weathering? Young scientists investigate the physical and chemical weathering of limestone (chalk) through experimentation. First, they conduct trials with different-size...

Young scientists participate in a hands-on experiment to explore Einstein's theory of relativity in a creative manner. They investigate various waves and compare their characteristics as they discuss how each wave is created....

Students review properties of matter and discuss how materials change when things are done to them. They observe how materials change as a reaction to temperature by following the procedure to make ice cream and recording the temperature...

Students use oranges to informally explore decomposition, dehydration, fermentation, the water cycle, bacteria, yeast, food webs, the needs of living things, and physical vs. chemical change over a period of three or more months.

Fourth graders make observations of the reactions that happens between calcium carbonate and various liquids. During the experiment the students determine if there is a chemical change, a physical reaction, or no reaction when they mix...

Elementary school physical scientists explore kinetic mechanical energy by dropping a golf ball on different surfaces. They discuss how human made materials might react to light differently from nature made materials. This lesson plan...

High schoolers explore and classify organisms found in a Rocky Mountain Ecosystem. Through discussions, students examine the effects upon an ecosystem if a component was removed or a new component was added. As a class, they survey...

In this matter worksheet, students write down 3 causes and effects of physical changes in matter. This worksheet is a graphic organizer.

Students explain scientists' ideas about the structure of the atom over the last century. They develop a pictorial history of the changing ideas about the atom and write a caption describing the scientific thinking behind the model.

Le Chatelier's interest in thermodynamics and building materials such as cement and plaster led to the Le Chatelier Principle in 1884. Activity 13 in a series of 36 extensively explores chemical equilibrium. Learners read about...

Students identify the characteristics and composition of emulsions. In this chemistry lesson, students classify household products according to emulsion type. They explain how to make the best emulsion.

For this science worksheet, students read 15 science definitions and determine which science vocabulary word fits  each definition. Students write their answers in the box that precedes each definition.

Students discover the history of hot air balloons by watching one ascent.  In this physics lesson plan, students utilize a Montgolfier Hot Air Balloon from an earlier lesson plan and record the temperature, rate of ascent and the...

Second graders look at different types of energy. In this energy lesson, 2nd graders define energy and the difference between kinetic and potential energy. They see examples with falling books and a slinky.

Starting with a simple food chain, young scientists interpret the difference and interrelatedness between herbivores, carnivores and producers. They answer questions related to cause and effect of food chain disruptions, including the...

In this matter worksheet, students complete a graphic organizer by writing in 1 thing that causes a physical change in matter and 3 effects this has on matter.

Students examine the differences between elements, compounds and mixtures. Using diagrams, they compare and contrast atoms and molecules and describe various chemical reactions. They distinguish the differences between ionic and...
