Design a Bobsled

3rd - 8th

Students apply their knowledge of friction, drag, mass and gravity as they design, build, and test mini-bobsleds.

Inquiry-Based Learning

Force and Motion

Students experiment with force and motion. In this force and motion lesson, students test gravity using a variety of objects. Students rotate through a series of stations which use force, motion, friction, and inclines. Students predict outcomes and compare to results.

Frictional Forces

Students explore friction.  In this middle school science/mathematics lesson, students collect and analyze data as they investigate the role of frictional force on motion.  Students examine their results to see when more force was needed to move the block and note the corresponding surface. 

Force and Motion - Part 2

Students test different objects such as dominoes, marshmallows, slides, and more to test their force, motion, gravity, friction, and the concept of matter. In this force and motion lesson plan, students understand that the force an object has relates to it's matter and gravity pull.

Playing with Parachutes

This lesson certainly will not be a drag! Little engineers design parachutes that make use of air resistance and, as a result, slow the descent of the payload as much as possible. It is an opportunity to teach about many motion concepts: air resistance, drag, gravity, Newton's laws of motion, etc. Primaries can simply design and test, while older learners are provided with background reading, a planning page, data tables, and evaluation questions to stimulate critical thinking. This resource will inspire your learners to reach new heights!

Investigating Friction

Young learners explore friction. They view a video or DVD (bibliography provided) and define terms related to friction,and work in groups to experiment with the effects of friction on speed and motion using ramps and toy cars.

Straight Line Motion

Students examine gravity, mass, and friction. In this speed and motion lesson, students investigate how straight line motion is impacted by gravity, mass, and fiction as they participate in a hands-on activity.

Marbles in Motion

Fourth graders explore how to play marbles while learning the scientific concepts of force, motion, mass, acceleration, friction, and inertia.

What a Drag

Young scholars learn examples of friction and drag, and suggest ways to reduce the impact of these forces. The equation that governs common frictional forces is introduced, and during a hands-on activity, students experimentally measure a coefficient of friction.

What a Drag!

Students demonstrate how drag affects falling objects. They create a variety of shapes out of paper, conduct an experiment in which they observe how size, shape, and weight affects the speed with which their paper shapes fall, and record the results on a worksheet.

Science: What A Drag

Learners calculate frictional force after examining the different types of friction and drag. Using a box, basket, and weights, they collect friction data and measure a coefficient of static friction. In teams, they answer questions based on the lesson.

Lesson Planet has helped me differentiate my classroom as needed. I always find it easy to adapt work for struggling learners but find it more difficult to adapt work for higher level learners. By using lesson planet I get great ideas to create fun, challenging work for my higher level learners.
