Where does the mass for a growing tree come from? Scholars consider a few different hypotheses and guess which is correct. They then analyze data from different experiments to understand which concepts science supports.

An interesting series of puzzles and word games are available in this multi-page collection, which focuses on coal. Learners practice math and language arts skills as they solve the puzzles, and learn many facts about coal at the same time.

Students use S'COOL data to identify factors that affect cloud formation. They find a data set using the S'COOL database , and use Excel to manipulate the data. Student isolate relevant data, create meaningful graphs from a spreadsheet,...

Viewers learn how to identify the substances in a chemical reaction, how to balance it, and the different types of chemical reactions by watching a presentation that also includes a review of monomers and polymers. The presentation...

Students explore the differnences between food producers in food webs and food consumers in food chains. Behavioral choices of primary and secondary consumers such as herbivores, vegetarians, carnivors, and omnivors are analyzed.

How are chemical bonds similar and how are they different? Provide your young chemists with the resources to more thoroughly understand the concepts of ionic and covalent bonds. Pupils research these topics, diagram examples of each...

Energize biologists with colorful images in an activity that captivates the imagination while demystifying the subject of cellular respiration. Participants build comprehension skills and access core content knowledge by analyzing text...

As your class views each slide, they will be introduced to the organelles and structure of the cell.  Details about structure and function are given and also some trivia about their frequency and population. There is also some...

Students observe water birds feeding at a local wetland, record what they see, and construct an appropriate menu for a "Waterfowl Cafe." They also play a "flocking" game.

Providing an overview of photosynthesis, this presentation would be a quick and easy way to go over information learned in class. This attractive and clear presentation would be a great way to kick off an exploration of photosynthesis.

Anytime you make concepts clear with role playing or hands-on experience, it's a win for the whole class. Ping-Pong balls are used to represent carbon in a carbon cycle role-play activity. In small groups, children first discuss what...

Food always gets attention! Model atomic structure using fruit loops to represent the subatomic particles. After building models, scholars create ionic bonds using their models. Finally, they use these concepts to create a periodic...

Which food molecules must be present for cellular respiration to occur? Scholars view an informative presentation to better understand the process of cellular respiration. It details each step, focusing on the locations and the four main...

In the 19th activity of 22, learners determine if distance from a light source affects photosynthesis. Participants capture oxygen in straws and find that the amount of water the gas displaces is proportional to the rate of photosynthesis.

Blend chemistry with cooking in this exploration of polymers, carbohydrates, and food science. Experimenting with gelatin produces concrete examples of the bonding and ploymerization discussed in the lesson. Copious, comprehensive...

High schoolers investigate the reaction rate of iodine and soluble starch. In this rates of chemical reactions lesson plan, students study the effects of varying concentrations of reactants and varying temperatures of reactants on the...
