What experiments can you do with plants?
Plant Project Ideas
- Do magnetic fields affect plant growth?
- Do different colors of light affect the direction of plant growth?
- Do sounds (music, noise, etc.)
- Do different colors of light affect the rate of photosynthesis?
- What are the effects of acid rain on plant growth?
- Do household detergents affect plant growth?
What is the best plant to experiment on?
Some of the fastest-flowering garden plants include sweet peas, marigolds, nasturtiums, nigella and sunflowers. The father of modern genetics, Gregor Mendel, used garden peas (Pisum sativum) for his experiments because they were easy to hand-pollinate.
What is the experiment of plant growth?
The plant-growth experiment is an example of a factorial experiment. A factorial experiment consists of several factors (seed, water) which are set at different levels, and a response variable (plant height).
How do different liquids affect plant growth experiment?
after giving plants different types of liquids for 5 days, the results show that the plants that were given water grew the tallest. The average height of the plants given water exceeds even the tallest height of the plants given milk and orange juice.
How does a leaf get water experiment?
Procedure for Leaf Experiment
- Start by taking a walk outdoors and collecting various leaves.
- Snip off the bottom of each leaf stem. Then place each leaf in a glass filled about a third of the way with water.
- Add red food coloring to the water.
- Observe the leaves closely.
- Observe them for the next two days.
How does light affect plant growth experiment results?
Plants deprived of light will lose their color and die. The shoots exposed to “limited/no” sunlight had a yellow/white color due to the fact that photosynthesis could not occur. The lack of sunlight stunted photosynthesis and therefore the sprouts were not able to produce the chlorophyll needed to create a green color.
What are variables in a plant experiment?
In science, there are three main types of variables: independent, dependent, and controlled. Think about variables for a question such as, “Does a bean plant grow best in sun or shade?” First, identify the variable that will be changed. In this case, the amount of light that the plant receives is changed.
What is the control in a plant experiment?
So what is being changed is the independent variable and the result or outcome is the dependent variable. The control variable is a variable in the experiment that is not changed and kept constant between the two groups.
What liquid helps plants grow best?
What Kind of Water is Best for Your Plants?
- To give your plants the absolute best, rainwater and bottled spring water are your best options.
- While distilled water won’t actually harm your plants, you will notice that your plants won’t grow as quickly or as tall as plants watered with rainwater or bottled spring water.
Why do bubbles appear in the leaf?
If you look closely at your leaves that were in the sunlight, you should see lots of very tiny bubbles. These are the escaping oxygen atoms which form bubbles since they are under water.
How do plants grow in preschool activities?
Make Science Exciting with These Plant Activities for Your…
- Record Appearance of the Green Bean. Each green bean is unique in appearance.
- Measure a Green Bean.
- Count the Seeds.
- Green Bean Taste Test.
- Plant a Seed in a Pot.
- Observe Sprouts in a Plastic Sandwich Bag.
- Plant a Seed in a Bag.
How do different colors of light affect plant growth experiment?
The plant under the green light actually grew the slowest. The plant that grew the fastest was the plant under the red light. The results of this experiment show a slight preference for growth for the red light followed by white or blue and then green light.
What are the dependent and independent variables for the plant experiment?
In this experiment, the addition of fertilizer is the independent variable manipulated by the scientist. Plant height is the dependent variable that responds to the change in the independent variable. Each plant is exposed to an equal amount of sunlight, so sunlight is the control variable.
What is the independent and dependent variable in a photosynthesis experiment?
Independent variable – the light intensity (how close the light is). Dependant variable – the number of oxygen bubbles given off (the rate of photosynthesis).
