Is your class ready to size up the topic of diffusion? Help them get cell shape savvy with a well-written handout. The resource covers how substances such as oxygen passively move through the cell membrane and how cell size and shape...

Get a surprised reaction from trying out the chemical reaction. Scholars conduct a chemical experiment by adding yeast to hydrogen peroxide and dish soap in a plastic bottle. They learn that yeast contains a catalase enzyme that releases...

Add a little heat to your science lesson. Young experimenters work to understand the chemical reaction taking place when a candle burns. They experiment with both oxygen and carbon dioxide to make conclusions about the reaction.

Most fish freeze to death when the water is too cold, yet some fish live in the Southern Ocean where the water is often below freezing. Scholars use two models representing the blood from most fish versus the blood from Antarctic fish....

In session one, demonstrate for your class how a flame eventually goes out when enclosed in a jar in order to teach that oxygen is required for combustion. In session two, class members then burn sugar in a spoon to observe how it...

Act out the circulation of blood in the body with an innovative activity. Kids act as either body parts or blood, and carry necessary nutrients and waste throughout different stations to represent the way that oxygen circulates. 

Provide your class with the opportunity to view our carbon cycle close up. Young scientists research the cycle of oxygen as it completes the tasks of photosynthesis and respiration. They explore the importance of carbon in an ecosystem...

Electrify your science class with this simple electrolysis experiment. After first reading about hydrogen and its potential as an alternative energy source, a demonstration is performed showing young scientists how water molecules can be...

Substances that decompose with the help of living organisms do so at different rates. Scholars experiment with Winogradsky columns to determine the rate of decomposition, the oxygen and sulfide content changes, and bacteria levels. The...

Is your class in the dark about photosynthesis? Shed some sunlight on an important biological process with a thoughtful activity. After answering questions to help determine their level of knowledge, learners work with chemical equations...

Give your class a colorful and tasty representation of the components of the mixture that we call air. Pop a few batches of popcorn in four different colors, one to represent each gas: nitrogen, oxygen, argon, and carbon dioxide. The...

How does energy from the sun make plants grow? Scholars move step by step through the processes that promote plant propagation during a detailed lesson. The resource illustrates ADP production and hydrolysis, then allows learners to...

Science teams make models of four different hydrocarbon compounds that we commonly use for fuel. Then they demonstrate chemical reactions that result when energy is produced. This can be used as an enrichment when your class is studying...

Young botanists examine the different parts of tress and then draw parallels between the functions of these parts and the function of parts of the human body. 

Young scientists know that water is H2O, but can they prove it? Through a simple electrolysis of water demonstration, scholars see the two gases produced as a result of a chemical reaction. Because this reaction doesn't happen...

How can the circulatory system compare to a city map? Pupils distinguish the "roadways" and "vehicles" of the cardiovascular system, compare the anatomy and function of veins and arteries, and review different types of blood cells with...

What is biogas and how is it made? After examining background information about the sources of biogas and biogas generators, class members follow the provided information and build a biogas generator that can be used in the...

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.

When an organism eats, how does food become energy? Young biologists follow glucose through the process of cellular respiration to the creation of ADP using a discussion-based activity. The resource also highlights conservation of mass...

Every muscle movement requires energy, but where does that energy come from? Scholars answer this question and more as they complete a worksheet. By following the directions, completing research, and discussing it as a class, they begin...

It's not easy to measure the weather. Pupils learn about what all weather has in common—the atmosphere. Scholars discover how a meteorologists must be able to measure aspects of the atmosphere and decipher the data. They then create a...

Engage in a shady activity to practice measurement techniques. Classes venture outside to collect measurements of various trees, using different strategies to measure the height, trunk circumference, width, and crown size. Then they...

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...

Take time to appreciate the beauty in the anatomy of animals with this cross-curricular art and science activity. After viewing examples of fish-themed artwork, children complete the included instructional activity by...
