Young scholars investigate materials that emit light. In this deep ocean instructional activity, students compare and contrast materials that emit light under certain conditions and infer the light-producing process. They explain three...

Students investigate the hardness of different water samples using the conductivity meter. In this chemistry lesson, students build their own meter following specific procedures. They identify an unknown sample of water.

Young scholars investigate osmosis and diffusion in a liquid environment. In this osmosis lesson plan, students use dialysis tubing made into bags and filled with 3 different solutions. They observe the movement of water molecules into...

Third graders explore the relationship of mass to volume. In this physical science instructional activity, 3rd graders participate in an investigation with a several materials and measure the mass and volume using scientific tools....

Students research and demonstrate volcanic activity. In this volcanism lesson, students research the types of volcanoes and define related terms using the Internet. They demonstrate volcanic activity with water, corn syrup, and flour.

Students explore the porosity of soil. In this soil lesson, students conduct an experiment which shows the porosity of different types of soil. They use sand, silt, and clay to see how soil particles are more or less aerated and thus...

When making sweet tea, why do people dissolve the sugar in hot tea instead of cold tea? The class discusses the previous lab and builds upon it. Working in groups, they design an experiment to determine how temperature affects the...

How much time does it take to jump over three balloons? Pupils calculate the speed of tasks that require different motions. They determine motions for tasks such as walking, skipping, hopping, and jumping before creating a...

There's more to fluids than meet the eye—they include gases, liquids, and polymers, too! Scholars complete three hands-on activities exploring different properties of fluids. They explore viscosity by measuring the resistance, or...

What is a reasonable percent yield in the manufacturing process? Scholars develop a process for producing chalk in the third lesson of a six-part series. Then, they must determine the theoretical and percent yield. Discussions about...

Students investigate scientific measurement. They use a variety of scales to do the job and communicate the results correctly. The teacher uses socratic questioning throughout the lesson checking for comprehension. Students measure some...

Third graders explore and identify the tools that can be used to measure length, mass/weight, and volume. They discuss how things are measured using different units, and observe the difference between the English and the Metric systems....

Fourth graders identify characteristics of a simple physical and chemical change. They describe objects by the properties of the materials from which they are made and that these properties can be used separate. Students describe the...

Fifth graders complete measurement problems where they use powers of ten, read metric measurement tools, estimate measurements, and more. In this measurement lesson plan, 5th graders complete 10 problems.

In this DNA worksheet, students access a website to determine the information that was used to understand DNA replication. Students compare the difference between observations and opinions. This worksheet has 7 short answer questions and...

Students stack several different colored marshmallows-one on top of the other-in the tall cylindrical container. They ct a cardboard disk to fit snugly inside of the container on top of the marshmallow stack using a compass if necessary....

Students use specific dimensions to create a box. In this geometry lesson, students analyze the different properties of two and three dimensional shapes. They make conjectures and use it to solve problems.

Set up stations around your science lab to introduce youngsters to different equipment. They examine a beaker, graduated cylinder, ruler, balance, and thermometer. The said worksheet is not included, but you will find a few useful tips...

Young scholars divide into groups of three or four, elect in their group who they think has the biggest mouth. This question will be followed by Mrs. Peters' joke about big mouths and frogs. Students then be asked how they could prove to...

Students investigate the potential toxicity of water samples using California blackworms to test water quality. They observe the worms' behaviors in different water samples and determine which sample has the highest toxicity. At the...

Students define density in their own words. In this physics lesson, students calculate density using mass and volume. They explain why some objects sink and some float.

High schoolers calculate the volume of scale model dinosaurs using a water displacement method. They use formulas to calculate the live mass each of the species of dinosaur. Then they complete and discuss a series of questions.

Young scholars estimate the live mass of dinosaurs. Using dinosaur and modern animal models, students use simple displacement methods to calculate the volume of the models. They calculate the masses of each model. Young scholars...

Students examine why having standardized units of measurement is important. They investigate the use of non-standard measure, twigs, while measuring the piece of tape. Next, they experiment with straws, paper clips, and rulers before...
