Plant respiration can be a difficult concept for young biologists to grasp; with a hands-on lab, learners can collect and graph data, then calculate the metabolism rate for the plants they studied. If you do not have a respirometer,...

What happens in the muscles during anaerobic and aerobic exercise, and how does this affect the heart and our overall health? A cross-curricular lesson that introduces learners to the lifelong benefits of exercise, including the...

Equip young campers with important survival knowledge with a set of engaging lessons. Teammates work together to complete three outdoor activities, which include building a shelter, starting a campfire, and finding directions in the...

Which of the following can you survive without for the longest time: water, food, or a positive mental attitude? The answer may surprise you. Guide learners of all ages through games, activities, and discussions about surviving in the...

Tune in! Young scientists use an AM radio at home to monitor solar output. The long-term project would be ideal in a flipped classroom or as an out-of-class project. 

How can organisms light up in water? Bioluminescence is light produced in a chemical reaction that can occur in an organism's body. First, learners determine what happens to light/color as you move into the deep ocean. In groups, they...

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...

How do scientists prove tiny living things respire? Young scientists build a respirometer and measure respiration rates in living creatures. By comparing the measurements of both plants and animals, they understand the similarities.

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...

Students build plankton models and compete to see which sinks most slowly. They write, or orally present ,the adaptations they incorporated to slow the sinking rate of their organisms. Race results can be grounds for some prizes!

Middle schoolers gain understanding of several of the biogeochemical processes in microbial mats. They acquire knowledge of the different roles of organisms in a microbial mat ecosystem. They understand how microbial mat ecosystems...

Give young scientists a new appreciation of fresh, clean drinking water. After learning about the ways astronauts recycle their air and water, your class will work in small groups creating and testing their very own water...

Go on a moon mining expedition from the safety of your classroom with this space exploration simulation. Using simple models of the moon's surface prepared ahead of time by the teacher, young scientists are challenged with locating and...

Global warming isn't just an issue on land; deep ocean waters are also showing troubling signs. Young scientists learn more about deep water corals and the many recent discoveries researchers have made. Then they examine data related to...

One document contains five different worksheets for practice naming and writing formulas for ionic compounds. The first is particularly notable, as it systematically walks beginning chemists through the process of using the periodic...

We know about the light spectrum, the age spectrum, and sound spectrum, but do chemical reactions also occur on a spectrum? Young scientists experiment with partial reactions on a spectrum and observe the color changes. Then, they...

In this percentage worksheet, students calculate percentages given various types of problems. They calculate percent of compounds in a solution, they calculate mass of compounds given percentages of solutions, and they percentages of...

Prepare your class for a quiz with these physical science review questions. Learners respond to 7 questions about ionic and covalent bonds, oxidation states, and chemical and physical changes. In addition, they name compounds and balance...

Wouldn't it be great if you could produce your own food? Scholars learn about the processes of photosynthesis and cellular respiration in plants. They consider how to use photosynthesis as a model of an efficient system and how to apply...

High schoolers solve five problems including finding the cross sectional area of two bodies, determining the swept out volume of a moving body, finding the average particle volume of a body and determining the collision time for a body.

As the title suggests, this is a simple summary of fossil fuels. There are no questions or problems to solve or no notes about fossil fuels. The notes cover how fossil fuels are formed, how we extract them, what humans use them for, and...

Students explore decomposition and soil health by creating their own garden.  In this agriculture lesson, students build a "lasagna garden" with organic matter found in the area and plant perennials native to their region....

Explore informative and explanatory writing with this lesson. Using a cube labeled with directives to describe, analyze, compare, associate, apply, and argue the topic, middle schoolers work individually or in groups to answer questions....
