Students review the components of a cell and the differences between plant and animal cells by creating a three-dimensional model of each type of cell. In small groups, they use modeling clay and household object to construct their models.

Students experiment to determine if yeast is a microorganism. In this yeast blowup lesson, students mix yeast with other ingredients and observe the results by using a balloon. Students adjust the amounts of the ingredients and test...

Students study and examine crystal shape. They create the two basic unit cells (one a tetrahedron) out of pipe cleaners and dip them into soapy water to see if they can form bubbles to represent a silicon atom in the center of a...

Students investigate plant structure and the process of photosynthesis. Using everyday items, they demonstrate that the leaves and stems of plants can act like a straw. In addition, they identify plant structure.

Students explore the concept of graphing data. In this graphing data lesson, students determine the percentage of sugar in bubble gum. Students graph type of gum vs. sugar percentage. Students create a table of their data.

Seventh graders investigate the scientific methods of testing the effectiveness of soap use against germs. They study the history and chemistry of soap as it has helped control the spread of germs. They make bubble soap.

Create a little scientific magic within your classroom! Learners mix powders and liquids and identify chemical reactions. Based on the reactions, individuals determine the identity of various powders.

If you aren't part of the solution, you are part of the precipitate! Young chemists learn about single and double displacement reactions including precipitation reactions, neutralization reactions, and gas forming reactions. They perform...

The arctic seas contain currents that are both warm (with high salinity) and cold (relatively fresh water) that circulate throughout the year. Through discussion, a lab, and a web quest, participants explore the impacts of melting and...

When it comes to the carbon cycle, the sky really is the limit. The lesson begins with observing a closed ecosystem in a bottle. Then, scholars discuss and answer questions on the carbon dioxide and oxygen cycles. 

Don't let all your hard work go up in smoke. Pupils conduct an experiment to see the harmful effects of cigarette smoke. They observe how smoke changes the color of white wool and an indicator solution.

Students are introduced to the differences between acids and bases and how to use indicators, such as pH paper and red cabbage juice, to distinguish between them. They make predictions that can be answered through scientific...

Students measure the amount of surface tension using a balance scale after a classroom demonstration students diagram the appearance of several liquids and label them.

First-grade mathematicians are encouraged to draw pictures to help solve ten word problems. Each of the problems will require your young counters to employ counting on strategies. The resource can be used for independent practice or...

Students connect starch to sugar as the storage form of energy. They find that no starch is produced in the plant without light. Students perform the old favorite of looking at starch deposition in geranium leaves using Lugol's iodine...

Learners build an air cannon and study air mass.  In this air cannon lesson, students create and shoot an air cannon and observe what happens.  Learners answer critical thinking questions about air mass and air cannons.

In this chemical change worksheet, students conduct 4 experiments set up around the room. They follow the instructions at each station for each experiment and list the physical properties and observe any changes at each station. Students...

Sixth graders experiment with the froth flotation process to extract metallic ore by using basic chemicals and equipment in the science classroom.

Students are introduced to the concept of mixtures. They identify materials used to make mixtures and describe what happens to the individual materials when they are mixed. In groups, they make bubbles by mixing water and soap together...

In this presentation worksheet, learners answer questions about five different topics presented in class. These include acid rain, acid etching, pH testing, cave formation and kidney stones.

Students explore primary and secondary colors. For this lesson on light and color, students complete four different activities which include mixing colors, creating secondary colors from primary colors and observing the colors in a bubble.

Students study the structure of the lungs. In this lung structure lesson, students use lung models to study the structure of lungs and experiment to measure the amount of air in the lungs.

Third graders explore the characteristics of whales that defines them as mammals. Using the internet and Inspiration software, 3rd graders create and organize "idea bubbles" to organize facts about whales. They locate details to...
