Students participate in two hands-on demonstrations to explore how friction can make objects hard to push.

Students investigate the sense of touch. In this senses lesson, students use their sense of touch to predict what objects are inside of a bag by feeling them with their eyes closed.

Students examine how dance steps can be done with different qualities. students perform their dance movement pattern with their choice of movement qualities.

Learners explore the 5 senses. In this biology lesson plan, students demonstrate the ability to identify objects through the use of the five senses as they complete 5 activities.

In this reading comprehension worksheet, young scholars read several short selections at 3rd grade level. Each selection is followed by 1-2 multiple choice questions. An answer key is given at the end of the set. 

[Free Registration/Login may be required to access all resource tools.] Overview of the structure and role of the endoplasmic reticulum, Golgi apparatus, vesicle, vacuole, and centriole. This tutorial also helps students distinguish...

Find out about the rough and smooth Endoplasmic Reticulum, and their functions inside a cell.

Students use a dichotomous key to sort materials into natural and man-made and sort further using the adjectives rough and smooth; this activity builds both science and language skills as students classify materials and build deeper...

In this lesson, students use previous knowledge about friction to formulate hypotheses concerning the effects of weight and contact area on the amount of friction between two surfaces. In the Associated Activities (Does Weight Matter?...

This lesson will discuss the structure and function of both rough and smooth endoplasmic reticulum. It is 3 of 6 in the series titled "Endoplasmic Reticulum."

This lesson will discuss the structure and function of both rough and smooth endoplasmic reticulum. It is 1 of 6 in the series titled "Endoplasmic Reticulum."

The endoplasmic reticulum is found in eukaryotic cells. The characteristics and functions of the smooth endoplasmic reticulum are described and it is then compared with the rough endoplasmic reticulum.

The difference between the smooth and the rough endoplasmic reticula is described, as well as the functions of the smooth endoplasmic reticulum. These functions include the synthesis of carbohydrates and lipids, protein transport, and...

Discover the organelles of a cell, and how their structure contributes to the cell's function.

Provides a labeled diagram of a plant cell and descriptions of the characteristics and functions of many of its organelles.

This lesson will discuss the structure and function of both rough and smooth endoplasmic reticulum. It is 4 of 6 in the series titled "Endoplasmic Reticulum."

In the first of two lessons of this curricular unit, students are introduced to the concept of friction as a force that impedes motion when two surfaces are in contact. Student teams use spring scales to drag objects, such as a ceramic...

This site provides information on the schematic and electron micrograph of endoplasmic reticulum function of both smooth and rough endoplasmic reticulum.

A good introduction to the structure and function of this cell system.

This Cells Alive page contains both schematic and description of endoplasmic reticulum.

[Free Registration/Login may be required to access all resource tools.] Considers the reflection of light from both smooth and rough surfaces and the law of reflection.
