Have you always wanted to take your science class on an amazing field trip they will never forget? Now you can! Observe the wildlife in an African savanna through trail cameras with a five-part data analysis activity. Learners analyze...

Should athletes carb load before an event or consume carbohydrates during the competition? Scholars discuss how to set up a hypothesis and experiment to answer a question relating carbohydrates and athletic performance. Then, they read...

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. 

The higher the number of letters in the final word for the National Spelling Bee, the higher the number of people killed by venomous spiders. Obviously, those two facts correlate, but no causation exists. Scholars view data based on...

Many variables impact your body mass, not just diet and exercise. Scholars collect and study data about body mass to better understand the complexity of a sensitive topic. They learn about leptin deficiency, the hypothalamus, and more.

How can you store lists in a computer program? The 16th installment of a 21-part unit introduces arrays as a way to store lists within a variable. Individuals program a list of their favorite things—adding interest to the activity.

Each of the Earth's spheres interacts with the other spheres in predictable ways. Young scientists explore these interactions through a hands-on activity, graphing, and watching a video. They summarize their knowledge in a video or...

Your class is asked to use inverse operations to solve eleven equations for unknown variables or to rearrange formulas to highlight a quantity of interest. By using the same reasoning as solving one- and two-step equations, algebra...

Don't cast a great hands-on resource aside! Scholars learn about the process of casting by actually trying out an example. Plaster of Paris and cookie cutter molds help them complete the activity.

Pupils often wonder how we know the distance to various stars. Starting with a thought experiment and progressing to a physical experiment, they determine the brightness and distance to various stars. The evaluation requires...

Can you determine how far down a rock drops without visual clues? Viewers observe a clip from a movie testing vertical distance only based on sound. They must determine if it is safe to drop down themselves or if it is farther than their...

Students consider what happens to herbicides or insecticides that are used in agricultural practices, especially herbicides that are used to control noxious weeds. They become acquaint with a chemical assessment method known as...

As an introduction to the skills required for and responsibilities of driving, pre-teens and teens engage in a series of activities, chart their response times, and analyze how variables effect these reaction times. Class...

Young computer scientists explore how to use the return command in computer programing by playing Go Fish. They learn about functions that return values and then write a turtle driver app using the return function. 

Here is a fun project. Sammy observes a chipmunk and a squirrel to see how many holes each needs in order to stash the same number of acorns.  Scholars could find the answer algebraically or create a table to analyze the...

How do scientists determine what questions to ask to meet their research goals? Help your class develop an inquiry mindset with a lesson based on studies in the Gorongosa National Park. Partners create their own research questions by...

Is it nature or nurture? In an easily adaptable kinesthetic activity to introduce genetics, learners group themselves based on a variety of categories. They will quickly find that some characteristics are easy to put in order, while...

Students conduct experiment with water striders by placing the insect in two different solutions and discuss their observations. They discover that weight and surface area are important factors in their experiment.

Students germinate seeds in unflavored gelatin to which liquid house plant food has been added. Students observe and record plant growth in this medium with a variety of variables in a number of experiments.

Students design investigations to test various materials to prevent heat gain in frozen water. The task assess students' knowledge of scientific inquiry including the following skills: observation, data collection, measurement,...
