Rutherford performed his famous experiment in 1907 with Marsden, showing the true atomic structure. This interactive simulation compares Rutherford's historical experiment to the Plum pudding model of the atom. In both models, alpha...

Positive and negative numbers are everywhere in the world around us. Whether it's charged particles in atoms, a hot air balloon rising and falling in the sky, or a series of bills and checks being delivered in the mail, this...

Salmonella poisoning impacts over 200,000 people in the United States each year. Scholars learn about the growth of these bacteria using multiple approaches. Then they apply the same growth calculations to endangered species and think...

What do consumers need to know about overfishing before buying fish? Scholars consider the question as they prepare for their performance task, which is to create a consumer guide for people about purchasing fish responsibly. After...

How in the world can something as big as the solar system possibly fit in your pocket? Complete this simple modeling activity and find out, as young scientists gain an appreciation for the incredible scale of outer space.

Caterpillars' and moths' most obvious change is physical, but what happens to their nervous systems as they complete metamorphosis? Through a hands-on investigation, young scholars construct the nervous system of a caterpillar. They then...

The most important chemical process on Earth is photosynthesis. Scholars explore the changes in the gases in our atmosphere as life on Earth developed. They create a model of photosynthesis and consider simple questions.

One way to study the microscopic is to make it macroscopic. Each slide of the lesson presentation presents a different molecular model along with a brief description of the compound's function. Learners use the information to build...

Making connections between a function, table, graph, and context is an essential skill in mathematics. Focused on comparing linear and exponential relationships in all these aspects, this resource equips pupils to recognize and interpret...

Learners construct a model of an electromagnetic spectrum using play-doh and string. They use exponents and plot the radio/microwave, infrared, and visible bandwidths of the spectrum.

The procedure for constructing a working model of the respiratory system is revealed in this resource. A wonderful approach would be to have biology learners work in pairs to create a model and write the suggested paragraph explaining...

Students build a scaled model of the solar system. In this space science instructional activity, students arrange them according to their distances from the sun. They analyze each planet's unique features such as density and relative...

Here learners get to flex some serious algebraic muscles through an investigation of logistic growth. The properties of the constant terms in the logistic growth formula are unraveled in a short but content-dense...

Bring the concept of conditional probability alive by allowing your classes to explore different probability scenarios. Many tasks have multiple solutions that encourage students to continue exploring their problems even after a solution...

There are plenty of fish in the sea, but only a few good resources on regression. Young mathematicians first perform a linear regression analysis on provided weight and length data for fish. After determining that a linear model is not...

Show scholars the importance of recognizing a normal curve within a set of data. Learners analyze normal curves and calculate mean and standard deviation.

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...

Young mathematicians explore the maximun area for patio with the added complexity of finding the mimimum cost for construction. First, they maximize the area of a yard given a limited amount of fence and  plot width v. area on a...

Using toothpicks, marshmallows, and round colored sticky dots, physical science enthusiasts build models of an atomic nucleus. In this eighth grade chemistry lesson plan, they play an atom-naming game with the models that they have...

Visualize methods of finding percents. Classmates find a percent of a quantity using two methods including a visual model in the 26th lesson in a series of 29. By the end of the lesson, scholars find percents given a part and the whole...

High schoolers determine the surface area of the Luxor Hotel, using the square feet of the base, volume, and the volume formula. They create a scale model of the triangular/pyramid shaped hotel.

Small groups devise a plan to find the bag that contains the larger percentage of blue chips. they then institute their plans and compare results to the actual quantities in the bags. 

Investigate polynomial factoring patterns by finding a connection to volume. As learners build a three-dimensional solid from smaller solids, they convert the visual model to a mathematical expression. Their models represent the sum of...

It's time to put the plan into practice. Using their plans from the previous lesson, scholars create multimedia and visual displays for their opinion speeches. Next, they watch videos of speeches and use a presentation rubric to evaluate...
