Provide a Hooke for a lesson on elasticity with an activity that has groups investigate a set of springs. They use a set procedure to collect data to calculate the spring constant for each spring using Hooke's Law. The groups...

Every year, the moon moves 3.8 cm farther from Earth. In the 11th part of 22, classes use the distance formula. They determine the distance to the moon based upon given data and then graph Galileo spacecraft data to determine its movement.

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

Students comprehend that ratios and fractions are interchangeable. They compare ratios using common denominators, cross multiplication, and intuition. Students find equivalent fractions. They comprehend that equivalent ratios do not...

Students solve the mystery of dead Mr. Potato Head using physics and algebra. They discuss Newton's Law of cooling as it applies to the mystery scenario involving a cooling baked potato as the "victim". They manipulate algebraic...

Learners calculate gas prices. In this transportation lesson, students tally the mileage and gas costs of their car for one months. They figure out how much was spent on gas and create a graph showing average gas prices over time. 

Students explore Newton's laws using CEENBoTs. In this physics lesson, students collect data and create tables and graphs. They calculate speed, acceleration and forces using mathematical formulas.

Students are introduced to Hardy-Weinberg Equilibrium without recourse to algebra. After participating in this activity, students gain a feeling for the significance of the Hardy-Weinberg Equilibrium without using algebra.

High schoolers explore the basic building blocks of our planet.  In this minerals instructional activity students begin the process of forensics on the basis of investigation and drawing conclusions from observations. 

Learners observe and/or conduct five experiments which address the Bernoulli Effect. In this conceptual lesson based on the Bernoulli Effect, the students construct atomizers, and make concrete observations and inferences in connection...

High schoolers view a video that reviews Mendelian genetics. They discuss the Hardy-Weinberg Law and use Popsicle sticks to simulate genetic variations and ratios in offspring.

Students visit a web page that gives a brief introduction to two color models and experiment with mixing different color intensities to create different colors. They visit links that give more detailed information on color.

Students analyze patterns of exponential models by collecting data in paper folding and M&M investigations. They use graphing calculators to create scatter plots that lead to equations for the exponential models. They then apply this...

Design and build a rover ... then eat it? This activity has groups of two design and build Mars rovers. The teams determine what instruments they want to include with their rover and plan a budget. They calculate the cost of the body of...

Students discover and discuss the differences between prokaryotes and eukaryotes. Using a microscope, they examine various prepared slides of prokaryotic and eukaryotic organisms.

Students identify oviparous animals. They brainstorm a list of animals that lay eggs, read "Chickens Aren't The Only Ones" by Ruth Heller and then add to the list. Students complete a booklet that shows an egg and an oviparous animal.

Eighth graders create their own cane flute. They use a model flute to gain the correct measurements and use the scientific method to construct the flute to have sound quality and pitch accuracy.
