![]() ![]() It is a twist of the traditional memory matching game, replacing visual signals with sounds.Įach activity will get more difficult as the children play along, so kids are not going to be bored. Kids touch the turtles to listen to their songs, and put those share the same pitch together. Matching singing beach animals: a fun activity for auditory processing and memory skills. It is a good activity for response inhibition skills.Ĥ. Kids also need learn to avoid using water balloons, which will water down the castle they are building. Again the complexity level increases over the time. Building Sand castles: kids will use the sand buckets to build sand castles. Kids will be delighted to see that the underwater scene comes to life after they put in the colors.ģ. While kids play more, the complexity of the scene increases. Coloring the underwater sea life: a fun activity for fine motor skills. It’s a good activity for parents to talk with kids about sharing and interacting with others.Ģ. The characters are going to have different reactions depends on if they get the gear they want. Returning beach gears to the owners: kids have to watch the visual signs to decide which gear belongs to who, and take each gear to the right character. In this 2nd app of the series, kids will have 4 activities:ġ. The design ideas for the activities in the app are from research findings in child psychology, developmental neuroscience, and early education. It is free right now.Īs stated by the developer team, the LumiKids series is not intended to be brain training for kids, but instead aims to be a digital play space that challenges cognitive, motor and social-emotional skills through intuitive and adaptive activities. It is another wonderful early learning app for toddlers, preschoolers, and kindergarteners. I liked their first app LumiKids Park, so once the new app is available, I checked it out right away. It is a series of apps from Lumosity designed specially for kids age 5 and younger. In particular, by plotting a HR diagram for either a globular or open cluster of stars, astronomers can estimate the age of the cluster from where stars appear to turnoff the main sequence (see the entry on main sequence for how this works).LumiKids just launched their 2nd app LumiKids Beach. The Sun is found on the main sequence with a luminosity of 1 and a temperature of around 5,400 Kelvin.Īstronomers generally use the HR diagram to either summarise the evolution of stars, or to investigate the properties of a collection of stars. These stars are very hot but have low luminosities due to their small size. white dwarf stars (luminosity class D) are the final evolutionary stage of low to intermediate mass stars, and are found in the bottom left of the HR diagram.Stars enter this evolutionary stage once they have exhausted the hydrogen fuel in their cores and have started to burn helium and other heavier elements. They have low surface temperatures and high luminosities which, according to the Stefan-Boltzmann law, means they also have large radii. red giant and supergiant stars (luminosity classes I through III) occupy the region above the main sequence.Main sequence stars have a Morgan-Keenan luminosity class labelled V. ![]() It is here that stars spend about 90% of their lives burning hydrogen into helium in their cores. The main sequence stretching from the upper left (hot, luminous stars) to the bottom right (cool, faint stars) dominates the HR diagram.There are 3 main regions (or evolutionary stages) of the HR diagram: Also plotted are the Morgan-Keenan luminosity classes that distinguish between stars of the same temperature but different luminosity. The giant branch is also well populated and there are many white dwarfs. By far the most prominent feature is the main sequence, which runs from the upper left (hot, luminous stars) to the bottom right (cool, faint stars) of the diagram. This Hertzsprung-Russell diagram shows a group of stars in various stages of their evolution. The giant branch and supergiant stars lie above the main sequence, and white dwarfs are found below it. By far the most prominent feature is the main sequence (grey), which runs from the upper left (hot, luminous stars) to the bottom right (cool, faint stars) of the diagram. The Hertzsprung-Russell diagram the various stages of stellar evolution. ![]()
