Learners explore the concept of density and buoyancy. For this physics lesson, students discover the different factors that affect an object's density and buoyancy in water. Learners conduct several investigations to further...

Students examine why diffusion and osmosis happen in an egg cell.  In this diffusion lesson students demonstrate a semi permeable membrane.

Students calculate the surface area of cubes, solids and cylinders. In this geometry lesson, students define the surface area formulas for different prisms. They calculate the surface area with 100%, and 80% accuracy.

Students classify polygons by name and shape. In this geometry lesson, students identify the lateral surface of each conic. They differentiate between cones, cylinders and spheres.

In this algebra worksheet, students apply the properties of transformation as they solve equations. They identify which equation is true and similar. There are 20 questions with an answer key.

Learners define and discuss salinity, conduct classroom experiment to determine salinity of water sample by using hydrometer, record predictions, and demonstrate understanding of how salinity influences object's ability to float in water.

Students explore physics by conducting a class experiment. In this density lesson, students examine a list of items and discuss whether they will sink or float and then determine their density. Students examine the objects over five days...

Students investigate geometric shapes through volume and dimensions. In this geometry lesson, students measure, weigh, and calculate sizes and volume based on estimation and calculation. They review important vocabulary related to prisms...

Students explore the concept of density. They use the the formula Density = Mass/Volume, one can determine where certain liquids and objects will settle in a graduated cylinder. In addiiton, they design a process to separate the liquids.

In this scientific method worksheet, learners read about the steps of the scientific method, ways to measure mass and volume and how to read a meniscus. Students use the scientific method to determine if an object is a liquid or a solid...

In this math worksheet, students sketch the graphs labeling the point of intersection in the first quadrant. Then they find the area of Ω.

Learners explore sources of  pollution runoff and actions that can be taken to reduce runoff.  In this pollution lesson students complete a worksheet and see why bio-essays may provide a more realistic picture of toxicity.

In this math practice exam instructional activity, students solve a total of 16 problems, adding, subtracting, multiplying and dividing fractions, simplifying expressions, finding values of expressions, calculating volume, finding...

Learners collect as much information as possible about their egg and record the information in a systematic way. They prepare a description of the egg your team was given that enable you to distinguish your egg from everyone else's egg.

Students discover that scuba diving is more than a sport. It's a science that operationally integrates physics, chemistry, physiology, and oceanography. They perform a simple experiment which simulates the air tanks used in scuba diving.

Students discover how salt water makes a pencil float better than freshwater by measuring and comparing the lengths of the portion of the pencil that floats above the water surface. They then determine if an unknown water sample is...

Pupils perform simple experiments to show properties of enzymes through studying how apple sauce can turn into apple juice and experimenting with papaya seeds. Students witness how enzymes speed up reactions through witnessing the...

In this maximum and minimum problems activity, students solve and complete 9 various types of problems. First, they find two numbers with a given sum. Then, students find the maximum and minimum value of each equation. They also find the...

Students indentify and differentiate between transit and surface food systems. Students measure energy that is released by various foods. Students compare and contrast cooking with solar energy on earth and what they might have learned...

Students calculate evaporation rate using differential equations. In this calculus lesson plan, students explain how pan evaporation works. They complete a worksheet to sum up the lesson plan.

Young scholars study Archimedes' Principle, flotation and the reaction of buoyant forces and explain the relationship between density and flotation.

Students explain the importance of water in our daily lives. In this aquatic science lesson, students identify different ways to purify water and make it potable. They design and construct a water filter based on researched information.

Students listen to the poem "Shapes" by Shel Silverstein in order to accurately and specifically describe shapes' rules/traits in their journals. They illustrate the poem and take turns reading during a creative shared reading session.

Students examine a Webmath page, and demonstrate how to copy and paste. They create a computer-generated template page presenting the attributes of two- and three- dimensional shapes.
