Beginning biologists demonstrate their grasp on cellular respiration, photosynthesis, and energy flow though ecosystems when completing this worksheet. Fifteen multiple choice and short answer questions test their knowledge. Because of...

After giving basic details about the properties of Carbon, some of the common functional groups and molecules are featured. There are some details about specific functions and impact on the human body. The diagrams are helpful and could...

Students examine the basics of starch and how it is used in food. In this photosynthesis lesson students experiment with variables that affect starch production in photosynthesis.

Delve into the differences among solids, liquids, and gases with this PowerPoint. It is both applicable and attractive. Large, colorful diagrams display the molecular arrangement of each state of matter and their properties are arranged...

Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...

Steel is an example of homogeneous mixture, also called an alloy, which is made of iron and carbon. The presentation introduces learners to elements, compounds, and mixtures. They explore their similarities and differences, and then take...

Measure the amount of energy in a peanut by igniting a chemical reaction. Classes use a laboratory setup to burn a peanut and measure the amount of heat it releases through a temperature analysis. They calculate the number of Joules of...

Carbon, the base for all organic compounds, exists in nature in its purest form as graphite or diamonds. The 25th lesson in a series of 36 teaches pupils the nomenclature of organic compounds. Learners read about how to use the IUPAC...

Learners explain historical findings such as Rutherford and Bohr's contributions, explain wave particle duality, and formulate Heinsenberg's uncertainty principle. They also draw s, p, and d orbitals, explain more historical findings,...

Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...

A fantastic presentation with great images should improve student understanding of lipids and their involvement in the body.  The chemistry of different fats, phospholipids, and steroids are explained. Additionally, the specific...

Students examine water's properties. They participate in hands-on activities to show the properties of water.

Learners perform a number of activities that mimic flamingo actions and displays. The class discusses why animals behave in certain ways, and how behavioral adaptations help animals to survive.

Here is an impressive and thorough lesson on estimation. Young mathematicians estimate how many kernels of popcorn can fit in a tablespoon, then how many tablespoons of kernels can fit in a baby food jar. The popcorn is then popped. All...

Stretch your teaching repertoire with an experiment on the elongation (stretching) and failure (break) of several materials. The point of the experiment is to design a composite material for chair webbing.

A great way to learn about molecular structures is to make a model. Gumdrops and toothpicks are used to construct crystal models. The models are based on theories of crystal shapes that occur because of positive and or negatively charged...

Young scholars treat a high molecular weight polyvinyl alcohol polymer with potassium periodate. They measure the viscosity of polyvinyl alcohols.
