OBJECTIVE: Exploring tools of discovery, Identifying tools that help us observe

VOCABULARY: binoculars, camera, discovery, eyeglasses, hand lens, microscope, telescope (optional/we used pics off the computer)

MATERIALS: worksheet

Children "discover" by using all their senses.  Students have been introduced to the five senses of hearing, touching, smelling, seeing and tasting.

Scientists and inventors have invented “tools” that help us to experience each of the senses in more detail.

The sense of sight probably has the most tools to help us observe and discover new objects.  Telescopes help us see the rest of the Universe, that we cannot feel, smell or taste.  We have instruments that can detect sounds that might help us understand our Solar System or the inside of our Earth.  Microscopes help us look at little things that we cannot see with the naked eye.   

  1. Ask students how they can see better.  As students respond, draw or write the "tool" they mention.  Display pictures of the items. 
  2. The following is a guide to help direct students comments.  Make sure you draw a simple stick figure so students have a guide when they draw.  Reinforce the concept that tools of discovery help scientists to see the world better.  Have students draw a picture of each of the instruments on the worksheet.

eyeglasses          helps people see                            
hand lens enlarges things
microscope makes little things large 
telescope makes very far things seem near
binoculars makes far things seem near
cameras records what we see

Continuing from yesterday we finished up our three part study on magnification and using the sense of sight to discover new ways of looking at and through things. Of couse the boys mostly wanted to play with the microscope while Sweet Pea ran around with the hand lenses (the non-expensive equipment ;). We wrapped the study by using the worksheet to make our own drawings of each object. Surprisingly they drew the pictures well enough to tell what was what. Again find the lab and fun others at Applied Science.

Happy Science Study,

A Mother's Prayer

Lord bless my home and anyone who enters. Lead me daily so that I am always aware of You! Whether educating my kids, cooking or cleaning may my attitude always be that of a servant. Give me the words to guide my children to You, to know You, Your character and love You, Lord. Please teach to have patience and to always be learning. Lord mold me through each stage of life so I am continually growing and pursuing You no matter what. Lord I want to be a great mom and wife and I know that if I look only to You for help that I can accomplish this, the love for my family that I desire to show them. Lord I'm amazed by You and I love You. Amen.

Full of Life, Full of Love

"The spirited child-often called "difficult" or "strong-willed"--possesses traits we value in adults yet find challenging in children. Research shows that spirited kids are wired to be "more"-by temperament, they are more intense, sensitive, perceptive, persistent, and uncomfortable with change than the average child." It seems as though we have three, and they are very much like me. What does this mean? I need to be compassionate, consistent, confident, controlled, all with a gentle yet firm approach. Yes my plate is full.

Motherhood: A rigorous training ground

What an awesome responsibility mothers have to their children. Cultural stereotypes promote the idea that giving birth miraculously endows women with kindness, compassion, and goodness. But we all know better. Many of us can witness that we are made more aware of our weaknesses and impatience after becoming mothers than we were before. Godliness and generosity are not prerequisites of giving birth; they are characteristics that God hones and whittles into our character over time. Motherhood provides a rigorous training ground where we can display practice and model the disciplines of love, honesty, and compassion before our children. --Rebecca Laird
