Young scholars review what the heart does and why the muscles in the body need oxygen. As a class, they measure their pulse rate while they are resting and after they have jogged for three minutes. They are helped by their teacher to...

Students feel and observe different types of materials. Using the internet, they sort objects based on the materials they are made from and justify their reasons for putting it in a certain category. They identify objects that could...

Students explore how a switch can be used to break a circut. Students construct a simple series circuit and use it for a purpose. Students read the "The Lighthouse Keeper's Lunch,or one of the "Katie Morag" stories which clearly shows...

Learners explore the effect of water, temperature and light on plant growth. Students are asked if they remember the LAW for plants. This is Light, Air(temperature) and Water, which all plants need for growth. Learners are divided...

Pupils identify and explain the parts of a flower and their role in the life cycle of flowering plants, including pollination, seed dispersal, and germination. Students recap the following information: that plants need light, warmth, and...

Learners identify how the pitch of an instrument can be altered. They complete a worksheet by labeling several images in order of pitch and then fill a bottle with water to create a sound that matches a pitch on a drawn card.

Pupils participate in a whole class discussion about solids, liquids, and gases. Students get involved in a teacher-directed experiment related to solids, liquids, and gases. Pupils complete worksheet, writing the names of the parts of...

Young scholars identify the changing states of water, water vapor and ice in the water cycle They investigate how each of these stages can be reversible. Students complete a worksheet describing the water cycle.

Learners predict the common classroom items, such as paper clips, chalk, keys, or erasers, that will be good conductors in a circuit. They build circuits using a variety of circuit diagrams to test their predictions.

Students explore animal diets and teeth. In this animal science lesson, students view photos of animals and their teeth. Students identify the type of diet the animal has based on the teeth. Students are introduced to the terms...

Students simulate block and tackles to lift heavy objects. They lift cargo by hand with the whip and the two-fold purchase to simujlate what crew members do aboard ships. They measure the effort and distance pulled for a gun tackle, luff...

The Thinking Fountain provides this simple experiment for understanding friction and it relationship to energy.

Forces are everywhere. Learn what they are, the characteristics of forces, different kinds of forces, and factors that affect them.

Explore the forces at work when you try to push a filing cabinet. Create an applied force and see the resulting friction force and total force acting on the cabinet. Charts show the forces, position, velocity, and acceleration vs. time....

Explore the forces at work when you try to push a filing cabinet. Create an applied force and see the resulting friction force and total force acting on the cabinet. Charts show the forces, position, velocity, and acceleration vs. time.

Explore the forces at work when pulling against a cart, and pushing a refrigerator, crate, or person. Create an applied force and see how it makes objects move. Change friction and see how it affects the motion of objects.

This Science Buddies project explains how to build a mechanism that will reproducibly swing a hammer so you can determine the amount of force needed to hammer a nail through various densities of wood. The Science Buddies project ideas...

This program gives students a visual representation of the forces on a block that is on an inclined plane. The students can watch how force gravity, force normal, and force friction change as the angle of the plane changes. Students can...

Learn about forces (push or pull), gravity, and friction in this module by training dolphins.

[Free Registration/Login may be required to access all resource tools.] In this module, students learn what causes friction, what factors affect friction, and how it is calculated.

Use your knowledge about friction to help Carrie get to the Invigatron before someone steals it. Following the activity, read more about friction and resistance, and then take a quick quiz to check for understanding.

Learn why every force is a push or a pull.

By the end of this section, you will be able to discuss the general characteristics of friction, describe the various types of friction, and calculate the magnitudes of static and kinetic frictional forces.

We all recognize what friction is, but do you really understand what causes it? This project focuses on friction, its causes and forces and specifically how it affects how fast you can slip down slides.
