Carnation Experiment Day 1

Transcription

1 Carnation Experiment Day 1 Foss CA Science Standards: Life Sciences 2 Different types of plants and animals inhabit the earth. As a basis for understanding this concept: o C Students know how to identify major structures of common plants and animals (e.g., stems, leaves, roots, arms, wings, legs). Investigation and Experimentation 4 - Scientific progress is made by asking meaningful questions and conducting careful investigations. As a basis for understanding this concept and addressing the content in the other three strands, students should develop their own questions and perform investigations. Students will: o A Observe common objects using the five senses. Lesson Goals: Student will be able to name and identify all four parts of a plant (Flower, stem, leaves, roots). Student will observe each part of a plant. Student will name and identify what a plant needs. Student will use their 5 senses to describe plant processes. Student will communicate observations through verbal communication. Materials: Carnations, Water, Plastic Cups, Food Coloring (blue, green, yellow, red), Sharpie Pencils, spacemen, observation papers, crayons, boards Preparation: Buy carnations and plastic cups Label cups with student names Directions: Anticipatory Set: Sing the Flower, Stem, Leaves and Root song. As an introduction to how stems work. Introduce Experiment: o Ask students what plants need to grow. Follow up with Where does the water go? o Put water in a plastic cup and add drops of food coloring. o Ask, What do you think will happen if I put the flower in this water? o Put carnation in the water. Pass out first sheets. Model how to do it on the board. Show the example. o Students will date and draw the white flower in the color water they want.

2 Then they will write the set up. o I put a while flower in colored water. Pass out prediction sheets. Model how to do it on the board. Show the example. o Students will date, write and draw their predictions. o Sentence Frame: I predict the flower will. o Students will color the water the same color they chose. If they think it will change colors, they will color the flower that color too. One by one call students up to place their carnation and food coloring in the water. Assessment: Formal Summative: Students will write the set up and predictions on their worksheet and draw a corresponding picture.

5 Carnation Experiment Day 2 (takes place a few days after day 1) Foss CA Science Standards: Life Sciences 2 Different types of plants and animals inhabit the earth. As a basis for understanding this concept: o C Students know how to identify major structures of common plants and animals (e.g., stems, leaves, roots, arms, wings, legs). Investigation and Experimentation 4 - Scientific progress is made by asking meaningful questions and conducting careful investigations. As a basis for understanding this concept and addressing the content in the other three strands, students should develop their own questions and perform investigations. Students will: o A Observe common objects using the five senses. Lesson Goals: Student will be able to name and identify all four parts of a plant (Flower, stem, leaves, roots). Student will observe each part of a plant. Student will name and identify what a plant needs. Student will use their 5 senses to describe plant processes. Student will communicate observations through verbal communication. Materials: Worksheets, pencils, spacemen, crayons Carnations from the day before Directions: Anticipatory Set: o Show flowers. Ask students what they notice. o Stretch Answers (Do flowers turn any color or the color of the water?) Observation Journal Part 1: o Pass out writing supplies and share ideas of what we could write. o Write the date. o Directed writing of: I observed the flower changed colors. It is the color of the water. o Students then draw a corresponding picture and color the water and flower the same color (same color as they used). Observation Journal Part 2: o Pass out second sheet. o Write the date. o Discuss how the water got to the flower. Stretch student answers.

6 o Directed writing of: We learned the stem drinks the water. o Color the water and color the flower the same color as the water. Draw arrows to show the water going up the stem. Assessment: Formal Summative: Students will complete two observation journal entries about their carnations.
