1. Witch’s Brew: This is a fun activity to do any time of year, but most specifically around Halloween time. The lesson learned is about the density of liquids. Here are the steps of the activity: 1. Get a large clear jug so that the children can see the liquids. 2. Get liquids of different density and color. 3. Tell the children that you are going to pour all the liquids into the jug. 4. Before you do, ask the children what they think will happen 5. Pour the first liquid which should be water into the jug.  Add food coloring to make the contrast of the liquids better and to add some fun to the activity. 6. Next add a liquid that you know will stay on top such as corn oil 7. Ask the children why they think the corn oil stayed on top and did not mix with the water. 8. Pour in the densest liquid. (In my case I used left over sun screen from the summer) 9. Ask the children why they think that liquid went to the bottom. 10. End the activity by talking about the different densities of the liquids. Note: the picture to the right shows an example of a Witch’s Brew with random things floating on top that the children put in to see if they would sink or float.

 

2. Temperature Graph: This is a good activity to start late February or early March. The teacher creates a large temperature graph. Once a week, the class will check the temperature and document the date and temperature on the graph. Explain to the children that when the graph bars go higher that means the temperature is higher. Ask the children to guess what will happen with the temperature the next week and record the children’s guesses. The following week compare the guesses with the actual temperature.

3. Balancing Act: Get a simple old fashion scale where you put objects on each side and see which object weighs more. Get 2 objects at the time and have the children guess which one weighs more and have the children explain their guesses. After the children guess put the objects on the scale to see which one weighs more. Then have a discussion on why an object weighed more. I.E.  discuss which object was bigger, what the objects were made out off etc.

4. Sink or Float: Get a bucket filled with water and a group of objects. Ask the children whether they think each object will sink or float and why. Then put the objects in the water to see if they sink or float. Afterward discuss why certain objects floated and why other sank.

4a. Sink or Float Boats:

Instead of just putting the objects in the water, have the children use tin foil to make boats and see how many objects (Lego people, or the picture example below Dinosaurs) they can put in their boat until it sinks.

5. Melting Ice: This is a good experiment to due in the when it is cold or hot outside and in conjunction with the aforementioned temperature graph. Overnight, freeze 2 cups of ice. At circle bring out the Ice. Tell the children we will keep one cup of ice in the classroom and put one cup of ice outside for an hour. Ask the children what they think will happen to each cup of ice and why. An hour later bring the 2 cups together and compare and contrast. Then hold a discussion about at what temperature ice melts at.

 

6. Pulsating Popcorn Kettles: Get a large cup of water and fill it about ¾ to the top.  Mix in 4 tablespoons of Baking Soda. Add in about 10-20 kettles of popcorn and some vinegar and wait a few minutes. The Kettles should start moving around in the cup.

 

7. Food Group Sorting

This is a fun hands on activity for circle time when learning about the food groups. You may either get pictures of various foods, or use food toys if available for the activity. Place all of the food pictures or toys in a bag in the middle of circle. Then have 5 boxes all around the circle each labeled with the name of one of the 5 food groups. Have the child pull out a picture of food from the bag then place it in the corresponding food group box. After all the food has been sorted, have each child create a meal for themselves by picking one food from each food group.

 

8. Alka-Seltzer Explosion

Materials: Test Tube, Cork, Water, Alka-Seltzer tablet, Paper , Crayons

Procedure:  Show the children the test tube filled with water. Tell them that you are going to put the Alka-Seltzer in the test tube and then put the cork on top of it. Ask the children to draw what they think is going to happen. Have the children tell the class what they drew and why they thought that was going to happen. Then put the Alka-Seltzer in the test tube and quickly put the cork on. The bubbles from the Alka-Seltzer should cause the cork to pop off. After that happens, ask the children why they thought that happened. Explain that the Alka-Seltzer caused a reaction that created a gas. The gas wanted to escape the test tube so it had to push the cork from the top of the test tube.

Goals: Have the children to use their fine motor skills to draw what they think will happen. Have the children understand that the gas caused the cork to pop off the beaker.

 

9. Eye Drop Art

Materials: Eye droppers, small bowls filled with different colored food coloring, construction paper.

Procedure: 1. cover the table with newspaper and then put all the materials on the table. 2. When the children come over, demonstrate how you fill and squirt with an eye dropper. 3. Tell the children they can use the different colored food coloring to decorate their piece of construction paper. 4. Ask them what will happen if they mix 2 different colors on the paper. 5. Then ask what other uses their might be for the eye dropper. 6. Use a blow drier to quickly dry the art work 7. Ask the children why the blow drier makes it dry faster?

Goals: 1. For the children to increase their fine motor skills and learn to fill and squirt and eye dropper. To have the children learn what happens when you mix certain colors together. For the children to have fun and be proud of the art work they created. Understand that the heat from the blow drier makes the picture dry quicker.

 

10. Magnifying Rocks

Materials:  Magnifying glasses, Discover Kids Rocks Alive Kit, and rocks found around town, paper, and pencils.

Procedure: 1. put out magnifying glasses and rocks from Discover Kids rock kit and other interesting rocks on the table 2. Have children examine the rock and try to find the type of rock in the Discover Kids booklet. 3. Ask the children differences that they see in the rocks. 4. Have the children draw what the rocks look like under the magnifying glasses.

Goals: 1. Have the children understand what magnifying glasses do. 2. Have the children use their words to describe differences in the rocks.  3. Have the children learn the names of some of the rocks. 4. Build the children’s fine motor skills and visual discriminations skills during the drawing of the rocks.

Possible Follow Up Activity: When the weather is warmer, go on a nature walk and collect interesting rocks to look at under the magnifying glass.
