What is a good recipe for making agar at home for a minimal cost? Are there materials that could be found in the kitchen cabinet?

Instructions 1 Place a coffee filter in a strainer and hang the strainer over the opening of the clear bowl.

2 Slowly pour the broth into the filter, making sure that the broth doesn't overflow from the sides of the filter. If the filter becomes clogged with particles, remove the used filter, replace with a clean filter and continue pouring the broth.

3 Remove the strainer and filter from the top of the bowl and observe whether the broth appears clear (i.e., there are no suspended particles in the liquid). If particles are floating in the liquid, repeat Steps 1 and 2 using a second clear bowl and a fresh coffee filter.

4 Place the pot on the stove and pour the clear broth into the pot.

5 Add 16 ounces of distilled water to the pot containing the broth.

6 Turn on the stove and adjust the heat to medium-low. Heat the broth to a simmer (i.e., small bubbles appear near the side of the pot).

7 Add 1 teaspoon of the agar-agar powder to the simmering broth (approximately 2.5 grams) and stir the mixture until the powder is dissolved. Make sure to stir the powder to dissolve and prevent the gelatin from sinking to the bottom of the pot (where it can burn).

8 Repeat Step 7 until all agar-agar powder has been dissolved in the broth.

9 Continue stirring the broth for about 1 minute to ensure that all powder is completely dissolved.

10 Turn off the stove, place the lid on the pot and let the liquid cool for at least 15 minutes.

11 Arrange the sterile petri dishes in a row for easy assembly, but do not remove the lids.If desired, place a trivet to hold the warm pot. If you're using lidded custard cups instead of petri dishes, sterilize the custard cups by placing the cups and lids inverted (upside down) on a foil-covered cookie sheet and bake in the oven for at least one hour at 375 degrees Fahrenheit. Make sure the sterilized cups and lids are completely cooled before use.

12 Carefully touch the outside of the pot to check that it is warm to the touch and place the pot on the trivet. If the pot is too hot to touch, wait at least 10 minutes to let the pot cool.

13 Remove the lid and set aside. Place the ladle in the pot.

14 Remove the lid from one petri dish and dispense nutrient broth to fill the dish halfway. Cover the dish immediately with its cover.

15 Repeat Step 14 for each of the petri dishes.

16 Allow the nutrient broth to solidify in the petri dishes for at least 1 hour, undisturbed.

17 Gently shake the petri dishes side to side to check that the nutrient broth has completely solidified. If the broth is not completely gelled, wait another 20 minutes before checking again.

18 Cover a table or flat surface with a roll of paper towels to create a sterile work area. Tear off a sheet of paper towel and fold it four times to create a thick, rectangular wad. Set this wad on one end of the work area.

19 Transfer one petri dish to the sterile work area and remove the lid. Carefully turn the dish over and place one end on the side of the folded wad, so that it lies inverted and slightly angled (with a slight gap by the paper towel wad).

20 Turn the lid over and place it above the petri dish on the sterile work surface. If water droplets appear on the lid, gently shake this moisture off before placing on the covered surface, but do not touch the inside of the lid.

21 Repeat Steps 19 and 20 for each petri dish, positioning one side of the inverted dish on the side of the previous dish rather than the paper towel wad. The dishes will appear as a staggered set, with gaps on one side so that excess moisture can evaporate.

22 Look at the inverted petri dishes to check whether the moisture on the sides of the plates evaporated. Once all moisture has cleared, turn the plates right-side up and immediately cover with the lids for use.

23 Inoculate the nutrient agar on the plate by wiping a swab containing the desired culture on the nutrient agar surface before covering with the lid. Turn the petri dish over so that the solid is on top. Store the inoculated petri dish with the solid on top for culturing and the lid on the bottom to catch any moisture, loose particles or growth.

10 Insanely Easy Ocean Science Experiments

Are you looking for some easy ocean science experiments? Don't want a ton of materials and spend tons of money and time gathering supplies for each experiment! Get excited, because we could be besties.

Here are the 10 ocean science experiments we did, for reals with our unit study.

Honesty time-- I lurv science and I lurv science experiments. I don't love getting them all together and buying the most random materials that I will NEVER use again, or have to specialty order and shipping costs more than the freaking product. And I'll NEVER use it again!! And we're eating beans for a month because we've blown our school budget.

So I love simple, easy, cheap experiments that teach the concept, let the kids learn and explore and get excited about the topic.

You'll see all the experiments we did, along with instructions, explanations, and pictures (when I remembered to take a few shots).

Like seriously, I forgot to take pictures of the density experiment, so I will re-do it just for you when the kids are sleeping. The sacrifices I make for those I love (that's you, in case you were wondering).

Skin Shield

The Science Lesson: How Your Skin Protects You Against Infection

So why exactly are we washing our hands so much? Our skin protects us from dangerous viruses, the COVID-19 virus included, so frequent hand-washing is important to stay healthy. In this experiment from Exploratorium's COVID-19 series, you'll poke holes in a tomato, then watch it for a week to see how bacteria and mold grow. The tomato will rapidly deteriorate for a dramatic lesson in just how helpful our skin is for protecting us. Best for kids ages 6-10 with parental supervision, and 11 and up independently.

Building in 1 Direction: The rods can be connected in-line without the intermediate need of a connector, almost reducing to half the quantity of parts required to build models.

Building in 2 Direction: While the assembled rod looks uniform with nothing protruding, it may provide building directions vertically and sideways by simply snap fitting another rod to one of the bi-directional side cavities. This innovative design allows snap assembly on both sides simultaneously and greatly enhances the expandability of the System.

Building in 3 Directions: The System is capable of tackling with the same ease as all the other building directions. All directions of the 3D space are accessible by combining the rods with the various types of connectors.

Connecting in Fixed Angles: This system makes it possible to build complex models that require connections of 45°

Triangulating: Structures Right angle triangles can easily be created, ideally with side lengths of 15 units. The advantage of the Engino System is that the 2D structure may at any time be converted to 3D without needing any additional connectors. The TEE and ELBOW connectors provide a change in the plane of building without having any elements protruding.

The model may be modified at any time and there is no need to substitute the connectors with different ones. This not only reduces the number of different parts required to make a model but adds to the simplicity and functionality of the System.

Connecting Everywhere: Engino rods can behave as bricks that achieve various lengths. What makes this System different than other building toy systems is that any length is possible with the patent-pending extendable rods.

This amazing feature, when combined with the pivoted joints, can lead to the creation of any triangular shape and construction that were previously inconceivable. The extendable rod replaces the need of numerous other components and maximizes the building capabilities of the System.

Connecting in Every Angle: The potential of the System is unleashed by “cloning” the innovative geometries to pivoted joints. A specialty designed component is free to swing around the pivot part allowing any angle of the 3D space to be created:

  • Expandable at any time, in any direction, in any angle
  • Rods are also connectors
  • All parts snap-fit and stay together
  • Any length is possible
  • Built “big and easy”
  • Simple to use
  • Maximized modification capabilities
  • Low number of different parts
  • Fewer components can build more models
  • Creative and educational

Building Machines: The optimized design of Engino components consists of only 18 different types of multi-functional parts. Yet you can build simple and complex machines. Following the same design principles of the basic system, a range of different types of gears, pulleys, axles and accessories make it the ideal constructional toy for home and school.
