If you need an array of worksheets to augment your science lessons, peruse a collection of assignments that is sure to fit your needs. With topics such as metric conversion, the scientific method, textbook features, research skills,...

The sun sends the earth 35,000 times the amount of energy required by all of us on the entire planet, every day. The fourth lesson in the 10-part series looks at how light energy from the sun transfers into thermal energy. Scholars build...

Enzymes play a role in almost every function in the human body. Scholars explore three variables related to the use of enzymes. They observe a catalase reaction, experiment with substrates, and examine reactions rates. 

Is it easy to make snow? Scholars use critical thinking skills as they investigate the concept of polymers by making snow. The class tests several different variables and takes measurements over the course of several days. They then...

Time to come clean! Scholars continue preparing the shampoo they created in the previous two lessons. The purpose of this stage is to calculate the perfect amount of additive to make the shampoo lather. 

I heard that oxygen and magnesium were going out and I was like "O Mg."  Pupils experiment with adding food coloring to water of various temperatures in order to determine how temperature impacts molecular movement. This is the...

Help your class come up with a procedure for comparing the dissolving rates of colored candy coating in different temperatures of water. If you are placing importance on controlled variables with your class, make sure that they use equal...

You might not be able to learn through osmosis, but you sure can observe it! Scholars observe and measure osmosis using chicken eggs. They control for multiple variables to determine which variables have an impact and how the impact...

How does gravity affect the life cycle of a butterfly? Learn first-hand what types of investigations astronauts perform in space by following along with one of NASA's experiments. Create butterfly habitats in the classroom with specific...

Bring the resource out from the shadows. Viewers of a short video learn about drive-in theaters and how operators project images onto a large screen. They then perform an experiment to determine the relationship between the distance of...

Open this lesson by demonstrating the production of acidic carbon dioxide gas by activated yeast. Emerging ecologists then experiment with seashells to discover the effect of ocean acidification on shelled marine organisms. They measure...

Milk does a body good ... unless, of course, someone is lactose intolerant. Pupils play the role of pharmaceutical scientists in a guided inquiry lab about lactase. Lab groups collaborate to learn more about lactose intolerance, how...

Alia-Seltzer tablets cause a very obvious chemical change, but do they also cause a temperature change? Each class member explores hot/cold packs, discussing how these temperature changes occur. Groups then design and carry out their own...

How does radiation affect our daily lives? Answer that question and others with a lesson that discusses radiation and its use in thermal energy transfer through electromagnetic waves. Pupils investigate vaporization and...

What makes particles attract? Here, learners engage in multiple activities that fully describe colligative properties and allow the ability to critically assess the importance of these properties in daily life. Young chemists...

How can you describe heat of fusion in a way the class understands and relates the importance of this concept to present day issues? In this third lesson of the series, learners conduct an experiment, demonstrating the flow of heat...

It's time to increase the heat! Young chemists demonstrate heat transfer and heat capacity in an activity-packed lab, showing the transitions between solid, liquid, and gaseous phases of materials. Individuals plot data as the...

Which modification is the best? Using the scientific method, pairs determine the effects of each control surface on the distance of a glider's flight. The activity, section 16 in a 22-part unit on aviation, allows pupils to gain a better...

How does water pollution affect the environment? Provide your class with the resources to answer this question as they learn about eutrophication and ecosystem changes. Over two weeks, they simulate the effects of pollution on the...

Young scientists roll up their sleeves and get a little dirty in this three-day earth science investigation. Following the scientific method, children monitor the growth of algae in pond water samples in order to determine...

Lead your biology class on a cell-sized adventure! Emerging scientists construct models of prokaryotes, then design an experiment to properly grow a bacterial culture. They conclude the activity by viewing the culture under a microscope....

Searching for a relatively interesting way to demonstrate Charles' Law? Here is a lesson in which pupils heat air inside a flask and then cool the flask to quickly cool the air. They make observations about what occurs during the...

If I want to build up my heart, where should I start? Science scholars use statistics in a sports physiology setting during an insightful experiment. Groups measure resting and active heart rates and develop a scatter plot that shows the...

The scientific method keeps you from believing only what you want to believe — it expands your mind. The lesson introduces the eight steps in the scientific process and how to design an experiment to biology scholars. Live insects...
