    Ask your child what they think Jell-O feels like in their hands. Then ask about liquid starch or thick liquid soap: maybe it is slippery or slimy or slick. Next ask what happens when the letters S and L meet? What are some other words that begin with the “sl” blend?


    1. Introduce that the letters s and l come together to make the “sl” blend which you say as one sound when you pronounce words.
    2. Brainstorm words that start with the “sl” blend. Draw from your child’s responses, but lead them in the direction of slime, slither, slide, slip, slick, sludge, sleep, etc.
    3. Ask them if they know what slime is.
    4. Introduce materials to make slime- cornstarch, water, green food coloring.
    5. Put an adult fistful of cornstarch a bowl.
    6. Add green food coloring to water. Caution: A small amount will go a long way.
    7. Pour a tiny bit of water into each bowl and let them mix ingredients together with their hands. It is much better to have them do the mixing with their hands than with utensils as the best part of slime is touching it.
    8. The slime will start to congeal and will seem rock hard. Have them pick it up and hold it in their hands. It will change from the solid, rock-like texture and ooze back into the bowl!!!
    9. The slick, sludgy slime will make them slither, slide and slip across the floor until they’re sleepy. (Or you are!) You should have already written out cards with each word on them. After they wash their hands, hold up a card and let them act it out.
    10. You could either storyboard the process using all the “sl” words you touched upon, or you could make up a “sl” book with drawings.


    Slime can also be made from green Jell-o. You could also use this as a “how to” and sequencing lesson with the “sl” words built in. Make green Jell-o as a class, but tell them it is slime. Something important to consider is that Jell-o has to be refrigerated for at least a few hours. I prefer to serve it in a somewhat half liquid/half solid form- it seems more like slime- but the solid Jell-o form would probably be equally exciting. They can either storyboard, write a recipe book, or an “sl” book for this. “Sl” charades and silly sentences are both great extension activities.

    For making Jell-o you will need:

    • Jell-o plastic cups
    • a big bowl
    • water
    • a hotplate
    • a pot
    • a refrigerator and/or ice

    *** Either of these are great for addressing forms of matter as well. Slime is a Non-Newtonian fluid meaning it is between a solid and a liquid. You can go over the differences between a solid, liquid and gas.
