Planned Read-Alouds: • Color Kittens by Margaret Wise Brown • The Lion and the Little Red Bird by Elisa Kleven • Mouse Paint by Ellen Stoll Walsh • Little Blue and Little Yellow by Leo Lionni

Activities:

Mixing Colors
Materials:
-Mouse Paint by Ellen Stoll Walsh - White paper - Paint palette (tempera paint/ finger paint) for each student - paint brushes for each student 1. Read the book Mouse Paint by Ellen Stoll Walsh 2. Ask children what happens when the colors mix together. 3. Ask, “How do you think the colors would change if we mixed our paint?” 4. Give each child their own paper, paint palette, and brush. 5. Explain to children that they all have their own paintbrush, paints and paper, and can use their paintbrush or fingers to mix their favorite colors on their paper 6. Encourage them to mix the colors while predicting and describing what happens. “Which two colors will you start with? What do you think will happen when you mix those two colors? Tell me what you see.” 7. Talk with children, and encourage them to talk with each other, about what they are doing and their resulting colors. Make references to Mouse Paint as appropriate: “The way you are using your paintbrush reminds me of the mice’s footprints!” 8. Give children a 5-minute warning for clean-up. 9. Remind children how to clean up and put away the brushes and paints. 10. Take dictation on pictures or on an index card, and when dry, display at children’s eye level. 11. During center time, make sure blue, yellow, and red paint are available at the easel, with large brushes and easel paper.

Water Markers
Materials:
- Markers and paper - ABC stencils (if available) - Water (in spray bottles or in bowls with paint brushes, so children can paint it onto their paper) - Smocks - Newspaper/ other protective covering for tables 1. Tell them that today they will get to use markers and water together and will investigate what happens when we mix the two together. Show them the materials. Tell them they can draw or write with the markers and then they will get to see what happens when they spray it with water. Ask for predictions.

2. Pass out materials and encourage children to begin drawing. Encourage children to write letters and words that they know, or use stencils to trace letters. Talk to them about their work and be sure to point out whenever you notice any letter-like symbols. Encourage children to explain what they are making: “What did you write?”; “Tell me about your picture”; “What do you call that?” You can reinforce color names as you comment on their pictures, but be sure not to ask close-ended questions about colors. 3. Allow children to add water (spray bottle or paint brush in water) to their picture and ask them to explain what they are observing. If students are having trouble describing what they see, you might ask “How are the colors moving? What do they look like now? Is this what you expected? Why do you think this is happening? Tell children that sometimes when you add water to something like markers; it makes the colors run or bleed. “Those are silly words to use for something like that! Why do you think we say that?” 4. Encourage children to write their names and see what happens when they spray water on it or when they write on wet paper. 5. Give children a 5-minute warning for clean-up time. 6. Look at each other’s pictures and notice what happened in different pictures. Ask children to describe if the same things happened to all the different colors. 7. Have children hang pictures to dry and wash hands.

Activities:

Making Oobleck
Materials:
- one bowl per child (can use aluminum pie plates, etc.) with 1/4 cup of cornstarch in each - water in small pitchers - 1/8 c. measuring cup or tablespoons (2 Tbs. = 1/8 cup) - smocks are optional since the oobleck cleans off easily once it is dried - newspaper for table to make clean up easier - “Science journal” for each child – fold a few pieces of paper in half and staple together in the center to create a book with multiple pages (or give each child a notebook if available). - Colored pencils, crayons or markers - Large paper & marker if desired to chart children’s predictions - Write recipe (including pictures) on chart paper in advance and hang where children can see it 1. Tell children that today they are going to be scientists. Show children their science journals and tell them they will record their observations (things that they notice) in their journals, just like real scientists do. Tell them that they will continue to use these journals for different experiments. 2. Have children observe and make comparisons between the cornstarch and the water. • Hold up one bowl with cornstarch in it. Make sure they can all see it. Each of you will get a bowl full of this white substance. What does it look like? How do you think it will feel? Demonstrate scooping up some cornstarch and letting it sift through your fingers. This is called cornstarch. Sometimes people use it for cooking.

• Hold up one of the water pitchers. Don’t refer to it as water yet. Do you know what this is? How is it different from the powder? If needed, point out that the water is wet but the cornstarch is dry. 3. Explain the activity to children while referring to the recipe chart. We’re making something called oobleck. We’re going to mix one small measuring cup [or 2 tablespoons] of water into the cornstarch. What do you predict will happen when we pour the water in? How will the cornstarch change? (Probe: What will it look like? How will it feel?) 4. Give each child his/her own bowl of cornstarch and help (only if needed) each one pour 1/8 cup (or 2 Tbsp.) of water into the cornstarch. Children can use fingers to mix. 5. Talk to children about what is happening. What happens when you stir the oobleck with your fingers? How does it look . . . feel . . . smell? What will happen if you squeeze it? What about when you let it go? Have bowl of your own and in addition to asking questions, make comments about what you are doing with your own oobleck. 6. Give the children a two minute warning. Two minutes is enough time to try one more prediction or Experiment if you are quick. 7. Move several containers of oobleck into the Discovery Area for children to continue exploring during choice time. (Do not stack bowls, or you may get mold!) 8. Give each child a science journal and put out something to write with. Have the children draw a picture of what they observed. Encourage them to add details to their drawings. “How did you make oobleck? What ingredients did you use? How much? What happened when you mixed the cornstarch and water? How did you mix them?” 9. Keep their science journals in the Discovery Area so that children can access them and encourage them to add observations during center time. Quick Reference:
Making Oobleck:

• Oobleck is usually a 2:1 ratio of cornstarch to water. Sometimes it takes a bit more of one ingredient; experiment ahead of time so that you know how it should act. • Over time the water will evaporate, so small amounts of water may need to be added as children play. • Don’t pour oobleck or cornstarch down the drain. The drain may block if oobleck solidifies inside it. Instead, pour or scrape oobleck into the garbage. If oobleck is on the tables, clothing or carpet. Simply let it dry. The water will evaporate and you will just be left with what is basically just cornstarch, which you can vacuum or wipe clean. Once most of the oobleck is scraped off hands it’s okay to wash them in the sink. Warm water will help get the oobleck off hands. • Do not stack bins or leave oobleck in closed containers. Oobleck will grow mold under these conditions. • Here are some interesting things to try with the oobleck while you are working with your bowl of the substance and modeling/describing for children: o Squeeze some oobleck to make a solid, then open your hand and watch the solid turn back into a liquid. o Create an oobleck ball and try to pass the ball to someone else before it liquefies. o Try bouncing an oobleck ball on the rest of the oobleck. o Measure how long it takes the strands of oobleck to drip into the container from a specific height once a ball has liquefied in your hand. o Rest your fingers on the surface of the oobleck and let them sink, then try to pull your fingers out of the oobleck quickly.

Activities:

Mystery Powder
- Baking soda and spoons - Water in child-sized pitcher(s) - White vinegar - Clear glass or large cup (for you to use to demonstrate) - 2 clear plastic cups for each child to view changes - Paper towels for clean-up - Science journals, colored pencils, crayons or markers

- Camera if available (can print photos to add to science journals later) 1. Tell them they are going to explore different liquids today and a special white powder. Show them their science journals and tell them that they are going to be scientists and record their observations (things that they notice). 2. Show children a pitcher of water and ask them what they think this liquid is. Let them smell it and describe what they see and smell. Show them the baking soda and allow them to smell and feel it and try to figure out what it is. Tell them that it is a mystery powder that their families might use when they bake. Have they ever seen a powder like this when they helped or watched their dad or grandma bake? Tell them it is called “baking soda.” 3. Ask children what they think will happen when they drop the baking soda into the water. Have them pour water into their cups and put baking soda in next. Listen for their comments or prompt them by asking, “What happened?” “What did you notice?” “What happened to the water/baking soda?” Do the experiment alongside them in the clear glass container, as they may have a better side view from your container. If a camera is available, take picture(s) to document what occurred in this part of the experiment. Have children draw/write in their science journals about what they observed; provide dictation. 4. Next have children look at and smell the vinegar. What do they notice? Have they ever smelled this before? When/ where? What do they think it is? What do they think it’s used for? Tell them it is vinegar. This can also be used for cooking (like in salad dressings or in special recipes) and sometimes people even clean with it! Ask children to predict what will happen when they put the mystery powder, baking soda, into the vinegar. Will it be like the water or will it do something different? 5. Help children pour a little vinegar in their second cup and have them take a little spoonful of baking soda and drop it in. Listen for their observations and comment on what they say. Match their enthusiasm, “Wow! What happened?! Did you think it would bubble up like that?” “How was this different from when we put the baking soda in the water?” If a camera is available, take picture(s) to document what occurred in this part of the experiment. 6. Give children a 5-minute warning for clean-up time. Before cleaning up, have children draw/ write in their science journals about what occurred. 7. Invite children to look at each other’s journal pages and comment on documentation. Remind them that they are scientists! Tell children that you are so happy they recorded what they saw in their journals, because if you forget what happened when the baking soda was added to the vinegar, you could pick up one of their journals, look at their observations, and remember what happened.

Color Creation
Materials:
chips/cards/swatches in varied colors, some cut apart into squares. Should be available free at a hardware store. - Paint in various colors including white and black - Small cups – Enough for 3children - Plastic lids or plates as mixing palettes - Paint brushes - Smocks - Large piece of white paper, divided into 4 sections 1. Show children paint chips from the hardware store. Hold up a paint card and ask children what they notice. “That’s right, these are all blue, but there’s something different about them … some are light blue and some darker blue [pointing]. Talk about how there are similar colors together but they are a different, some are darker or lighter. 2. “We are going to create our own paint chips. We are going to use paint colors that we already have and
- Paint

mix them to create new colors.” 3. Show children how their paper is divided into four sections. Explain that they will mix the paint on their palette (plastic lid/plate) and then paint the new color in one square of the paper. They can mix a new color to paint each section of the paper. 4. Have each child choose one paint color and one small cup of black and one small cup of white (so they have 3 cups each). “Which of these colors will you use? Oh, you chose red. I wonder if you are going to make it darker or lighter?”, “Oh look at that color you made! How did you make that? How much white paint did you add?” 5. Encourage children to explore, describe and compare the colors they are creating. Encourage them to be creative, thinking about objects or feelings that the colors remind them of. Model comparative language such as darker, lighter, brighter, similar, different, happier. Also model descriptive language like, hue, pale, tint, shade, excited, tired, bright, etc. Write their suggested color names in the section of the paper it is located. 6. Ask children to suggest names for the new colors they’ve created. Ask children to think about things the color reminds them of. “That color is dark like the sky at night.” “This one reminds me of the ocean.” “Look at this color Jason made. What does that remind you of?” 7. Give children a 2-minute warning before clean-up.
