How are skyscrapers built? What does it take to make a structurally sound building? How can one work within a budget to complete a building project? These guiding questions will be investigated and answered within a hands-on...

Hate to vacuum, but enjoy using a vacuum pump? Explore a instructional activity that starts with a demonstration of boiling water at various temperatures by using a vacuum pump. Then scholars design their own experiments to measure vapor...

A resource rich in information—and nutrients. Learners create agars for the purpose of cell cultivation in Petri dishes. The lesson provides instructions on how to create agars for the cultivation of different microorganisms.

Learners predict when an object will float or sink based on comparison of density of the object to the density of the substance in which it is placed. The access a website and sketch the object in the first column of their table and then...

In this Earth's environment worksheet, students complete a crossword puzzle given 35 clues about a variety of topics related to our Earth. Topics include ecosystems, precipitation, biomes, energy transfer, soil, weathering and rocks.

Learners explore the solar system. In this planets lesson, students learn about the other planets in the solar system. They watch a video clip from National Geographic on the solar system, compare and contrast the planets and create a...

In this chemistry learning exercise, students complete 12 short answer questions and problems on water vapor equilibrium. They calculate equilibrium concentrations of reactants and products.

Students explore the concept of density. In 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 red...

Students investigate why cells divide. In this cell size lesson plan, students observe how far a solution travels into 3 different size model cells of agar. They answer questions about the most effect movement of "nutrients" into the...

Students perform two experiments to show the properties of enzymes. They use pectinase to produce apple juice from applesauce to show enzyme action and then taste the difference between raw and boiled papaya seeds as evidence of enzyme...

Students explore the basic geometric shapes and geometric shape vocabulary through the use of geoboards and virtual geoboards. They create a variety of shapes with a partner, build ten different rectangles on their geoboards, and...

Learners investigate the gas laws and how they apply to changes in gases. In this gas laws lesson, students use Boyle's Law and Charles' law to show the relationships between pressure and volume and volume and temperature of gases.

Students participate in experiments at five stations to practice measurement. In this measuring lesson, students are presented different produce and objects and must measure with an appropriate tool. Students use metric and customary...

Students consider what happens to herbicides or insecticides that are used in agricultural practices, especially herbicides that are used to control noxious weeds. They become acquaint with a chemical assessment method known as...

Students examine the properties in oil in water. In this mixture lesson, students read about the Lophelia II 2010: Cold Seeps and Deep Reef Expedition and look at images of deep sea ecosystems. They experiment or participate in...

As your young learners develop into cooking enthusiasts, ensure their success in creating their next culinary masterpiece by preparing them to read and understand basic recipe terminology. 

Here is a good lesson which aptly describes how to do the classic "Oobleck" lab with your young scientists. Unfortunately, the "Oobleck Investigation Sheet" in the plan doesn't open. However, this is a very clear description about how to...

Third graders explore tessellations and the spatial concepts used in creating them.  In this tessellations lesson, 3rd graders rotate, reflect and transform shapes to create tessellations.  Students become familiar with the...

Students design a simple boat and predict how much weight it can carry. They should also discover why objects float or sink and how this can be determined experimentally. A great lesson on buoyancy!

In this experimental relationship worksheet, students read about direct and indirect relationships between variables in experiments. They answer three questions about relationships between variables.
