Students measure their smile with a piece of string, which is then measured on a ruler (metric of course!). They take a piece of string and cut it to the length that matches their smile and then measure it with a ruler.

Students explore their feelings when someone smiles at them. In this smiles lesson, students practice listening skills while discussing what makes them smile with a partner.

Students examine the emotions behind different facial expressions. They explain how it feels when someone smiles at them and practice smiling and speaking to someone with eye contact. They also demonstrate the characteristics of active...

Middle schoolers investigate the structure of the atom through hands on activities. In this atomic structure lesson plan, students perform 4 activities showing indirect evidence of the structure of the atom and the parts of the atom....

Students observe obscertainers through indirect observations and make hypotheses about the internal wall structures of the containers. In this indirect observation lesson plan, students make observations of 4 obscertainers with a steel...

Students grow crystals in the lab using solutions. In this crystals lesson plan, students set up a crystal growing apparatus using a sugar solution with a thread attached to a piece of copper wire that is inserted in the solution....

Eighth graders investigate polymers and their structures. In this polymers lesson plan, 8th graders perform 6 activities to learn about polymers and their molecular structure. They categorize a bag of items as polymers and non-polymers...

Students prepare artificial flavorings and fragrances. In this esters lesson, students combine an acid and an alcohol of choice to make an ester. Water is released and they produce an artificial flavoring or fragrance. They answer 4...

Students investigate static and current electricity. In this electricity lesson plan, students observe 4 demonstrations and conduct 3 activities to explore the repulsion of electrons and the attraction of protons and electrons. They...

Students observe and collect data about the earthworm. In this observation of an earthworm lesson plan, students use an earthworm to determine the effects of light and incline on the earthworm's behavior. They practice making...

Students explore the concept of density. For this density lesson plan, students determine the density of a crown and a sample of clay. They hypothesize about the densities of 4 liquids they are given including molasses, cooking oil, a...

Students investigate gases and their properties by completing 4 activities. In this gases lesson plan, students perform activities to show that gases take up space, they diffuse, and that odors and vibrations pass through gases. They...

Young scholars investigate the acidity of foods using titration. In this acidity of foods lesson plan, students find the acid concentration of 4 fruit juices by titrating them each with sodium hydroxide and an indicator to find the end...

Students review telling time to the hour and half hour on an analog clock. For this time lesson, the students learn how to determine the time in each of the 4 standard time zones.

Students learn that vibration makes different types of sounds. In this sound lesson, students perform experiments to understand vibrations and high and low pitch sounds. Students learn that sound travels differently through different...

Students analyze the function of the lungs. In this lesson about the Respiratory System, students explore breathing and the movement of air through the lungs. Students perform an 4 part experiment to observe what it might look like for...

Young scholars explore the sense of taste. In this biology lesson plan, students consider 4 types of tastes, recognize the papillae or receptors on the tongue, and locate and label the different taste sense organs on the tongue.

Students explore Newton's 3rd Law of Motion. For this physics lesson, students participate in various experiments that demonstrate the idea of action/reaction, such as a balloon launch, a skateboard activity, and a spring scale...

Students consider how food is converted to energy. In this science lesson plan, students explore the importance of eating properly with a balanced diet as they study 4 food groups.

Students experiment with graphing. In this graphing introduction lesson, students complete four activities: 1) a bar graph based on class birthdays 2) an estimation graph of the raisins in raisin bread 3) another estimation example with...

Observe the stages of the water cycle by completing 3 activities. To help understanding of the water cycle your students can observe evaporation, the formation of frost, vapor and water and the process of distillation which is used to...

Children explore fractions on a conceptual level by making individual quilt squares. Each student works with small paper swatches to divide them into pieces that represent a given fraction. The class is then separated into groups and...

Students explore the realms of measurement. In this math lesson plan, students analyze and solve problems in which rectangles with identical perimeters are compared to maximize or minimize area. This lesson plan can be extended for...

Mixed numbers can be added conceptually, algorithmically, and physically. Have the class visualize mixed numbers by adding fraction bars together. They then discover the algorithmic process that simplifies adding mixed numbers. Finally,...
