11 First Grade Science Projects to Pique Everyone’s Interest

Teachers

1. Sink or Float Experiment: Fill a tub with water and gather various objects like a ball, paperclip, and toy car. Have the students predict whether each object will sink or float, then test their predictions.

2. Plant Observation: Give each student a small plant and have them observe and document its growth over a few weeks. They can record the changes in a journal or create a visual display.

3. Magnetic or Not?: Provide a variety of objects, some magnetic and some not. Have the students use magnets to determine which objects are attracted and which are not.

4. Shadow Exploration: Take the students outside on a sunny day and have them observe and measure the length of their shadows at different times. They can create a graph to show the relationship between the time of day and shadow length.

5. Oobleck Investigation: Make a batch of oobleck (a mixture of cornstarch and water) and have the students experiment with its properties. They can try to make it solid or liquid by applying different amounts of pressure.

6. Rainbow Eruption: Fill a jar with water and have the students add a few drops of food coloring to represent different layers of the Earth. Then, add baking soda and watch as a colorful “eruption” occurs.

7. Balloon Rocket: Inflate a balloon and attach a string to it. Set up a straw track and have the students release the balloon, observing how the air pressure propels it forward.

8. Lemon Battery: Cut a lemon in half and insert a copper coin and a zinc nail into each half. Connect the two metals with a wire and watch as the lemon produces enough electricity to light up an LED.

9. Rainbow Milk: Pour a shallow layer of milk into a dish and drop food coloring on the surface. Then, add a drop of dish soap and watch as the colors swirl and mix together.

10. Dancing Raisins: Drop a few raisins into a glass of carbonated water and observe as they dance and move around. This demonstration shows the effects of carbon dioxide gas.

11. Color Changing Flowers: Place white flowers (such as carnations) in jars filled with water and food coloring. Over time, the flowers will absorb the colored water and change their appearance.
